Calendula Farming in Papua New Guinea: A Guide to Growing, Harvesting and Selling Calendula Flowers

Introduction

Calendula farming could become an interesting small-scale agricultural opportunity in Papua New Guinea (PNG), particularly for farmers interested in ornamental flowers, dried botanical products, seed production and natural skincare ingredients.

Calendula, scientifically known as Calendula officinalis, is commonly called pot marigold. It produces bright yellow, golden and orange flowers that can make gardens, school grounds and farms attractive.

Beyond its ornamental value, calendula is cultivated for its dried flowers and petals, which are used in herbal teas, botanical preparations, cosmetics and other specialty products.

For farmers in Banz, Jiwaka Province, calendula could be worth testing as a new crop. However, its suitability for local conditions and the availability of reliable buyers must be established before investing in large-scale production.

This article explains how to grow calendula, harvest and dry its flowers, collect seeds, investigate market prices and develop a small farming business in PNG.

1. What Is Calendula?

Calendula is a flowering plant in the daisy family, Asteraceae. It is cultivated in many parts of the world as an ornamental flower and as a source of botanical ingredients.

The plant produces yellow or orange flowers and grows well in sunny locations with well-drained soil.

Calendula can be grown in:

Home gardens.
School gardens.
Flower beds and borders.
Smallholder farms.
Dedicated botanical flower gardens.

It is relatively easy to grow from seed, and established plants can produce flowers over an extended period under suitable conditions.

Calendula should not be confused with French marigold or African marigold, which belong to the genus Tagetes. Anyone purchasing seeds for commercial calendula production should look for the botanical name Calendula officinalis.

2. Why Consider Calendula Farming in PNG?

PNG farmers often grow food crops for household consumption and local markets. Introducing specialty flowers could provide another agricultural activity, particularly where farmers can access suitable growing conditions and buyers.

There are three potential business opportunities for calendula.

A. Ornamental flowers

Calendula can be planted around homes, schools, offices and community facilities.

For schools, it could improve the appearance of the grounds while providing practical lessons in agriculture, plant propagation, environmental care and small-business management.

B. Dried flowers

Calendula flowers can be harvested and dried for sale to botanical ingredient traders, herbal product manufacturers and specialty retailers.

Dried products may be easier to store and transport than fresh flowers, provided they are processed correctly and protected from moisture.

C. Seeds and skincare ingredients

Farmers can collect mature seeds for future planting. Once the plants are established, seed production may reduce the need to purchase new seed every season.

Calendula flowers are also used in skincare formulations, including infused oils, balms and creams. However, selling ingredients to cosmetic manufacturers requires suitable quality standards, and manufacturing finished cosmetics involves additional safety and regulatory requirements.

3. Can Calendula Grow in Banz, Jiwaka Province?

Calendula generally prefers full sunlight, moderate moisture and well-drained soil. It can tolerate some light shade, but deep shade may reduce flowering.

The Food and Agriculture Organization's Ecocrop database describes calendula as a crop suited to bright conditions and well-drained soils. Its listed optimal temperature range is approximately 16–26°C.

These characteristics make a small growing trial in Banz worthwhile. Nevertheless, local rainfall, soil drainage, sunlight and disease pressure will influence performance.

Recommended growing conditions

Sunlight: Choose a location receiving several hours of direct sunlight daily.

Soil: Use fertile, loose soil that drains well. Avoid places where rainwater collects around the roots.

Moisture: Keep the soil moderately moist while seedlings establish, but do not allow the roots to remain waterlogged.

Air circulation: Leave sufficient space between plants to help foliage dry after rain.

Weed control: Remove weeds regularly so that young calendula plants receive sufficient light, water and nutrients.

Because Banz can experience cool weather and heavy rainfall, it is important to test calendula before establishing a large commercial field.

4. How to Plant Calendula Seeds

Calendula is normally propagated from seed.

Step 1: Obtain the correct seeds

Look for packets labelled:

Calendula officinalis — Pot Marigold

In Lae, farmers can enquire with agricultural suppliers such as Chemica about availability or special orders. Stock must be confirmed directly with the supplier.

Step 2: Prepare the nursery

Prepare a clean seed tray or nursery bed containing loose, well-drained growing medium.

Avoid using soil that remains saturated after rain.

Step 3: Sow the seeds

Sow seeds approximately 0.5–1.5 centimetres deep, following the packet instructions. Cover lightly with soil and water gently.

Step 4: Allow germination

Under suitable conditions, seeds commonly germinate within approximately 5–15 days.

Keep the soil moist but not saturated while the seeds germinate.

Step 5: Transplant the seedlings

When the seedlings are strong enough to handle, transplant them into prepared beds.

A preliminary spacing of approximately 20–30 centimetres between plants can be tested, with wider spacing where airflow is particularly important.

For a commercial plot, record the spacing used so that you can compare plant health and flower production.

Step 6: Maintain the plants

Remove weeds, monitor for pests and diseases, and water during dry periods.

Avoid excessive fertiliser, which can encourage leafy growth without necessarily improving flower production.

Step 7: Encourage repeated flowering

Harvest flowers regularly as they open. Removing spent flowers can encourage further flowering.

Keep some healthy flowers on selected plants until the seeds mature if you want to produce your own seed supply.

Growing guidance from Utah State University Extension and the University of New Hampshire Extension provides additional information about calendula planting and care.

5. When Does Calendula Begin Flowering?

Calendula can begin flowering approximately 6–10 weeks after sowing under suitable conditions, although varieties and growing conditions affect the timing.

For planning purposes, farmers should allow approximately 2–3 months for an initial growing trial to produce useful observations about flowering.

Once flowering begins, the plants may produce flowers repeatedly rather than producing the entire crop at once.

This creates an opportunity for repeated harvesting, but it also means that labour must be available to collect flowers regularly.

For Banz, record the following:

Date of sowing.
Date of germination.
Date of first flowering.
Number of flowering plants.
Weight of flowers collected at each harvest.
Rainfall and any pest or disease problems.

These records will help determine whether calendula is suitable for commercial production in the area.

6. Harvesting Calendula Flowers

The flowers are the main product for farmers interested in dried calendula.

When should flowers be harvested?

Harvest healthy flowers when they are fully open and in good condition. Avoid flowers that are mouldy, damaged, dirty or deteriorating.

Choose a dry period for harvesting whenever possible. Wet flowers take longer to dry and are more vulnerable to mould.

Harvesting method

Inspect the plants and select healthy, fully opened flowers.
Use clean scissors or suitable harvesting tools.
Place harvested flowers in clean containers.
Keep the flowers away from soil and other contaminants.
Move the harvest promptly to the drying area.
Separate damaged flowers and unwanted material.

Calendula flowers can be harvested repeatedly throughout the productive flowering period.

Farmers should record fresh flower weights at each harvest. This information is essential for calculating dried production and determining whether the crop can generate a worthwhile income.

7. How to Dry Calendula Flowers

Correct drying is one of the most important parts of a dried-flower business.

Poorly dried flowers can lose their colour, develop mould or become unsuitable for commercial use.

Recommended drying procedure

First: Sort the flowers.

Remove damaged flowers, insects and foreign material.

Second: Arrange the flowers in a thin layer.

Use clean drying trays or food-safe mesh. Avoid piling flowers into deep heaps.

Third: Dry in a protected, ventilated location.

Keep the flowers away from rain, dust, animals and direct contamination. A suitable food dryer may provide better control than open-air drying.

Fourth: Monitor the drying process.

Turn or rearrange the flowers gently when necessary to promote even drying.

Fifth: Check the finished product.

The flowers should be thoroughly dry before packaging. Commercial buyers may specify a maximum moisture content or other quality requirements.

Sixth: Package and store correctly.

Use clean, moisture-resistant packaging and store the product in a cool, dry, dark place.

Do not seal flowers that still contain excessive moisture. Moisture trapped inside packaging can cause mould and destroy the entire batch.

For commercial sales, ask the buyer for written specifications covering moisture, colour, cleanliness, packaging and acceptable levels of foreign material.

8. How Much Fresh Calendula Is Needed to Produce Dried Flowers?

The amount of fresh flowers required to produce one kilogram of dried calendula depends on the variety, the condition of the harvest and the drying method.

For initial planning, a farmer might test a fresh-to-dried ratio of approximately 5:1 to 7:1. This is only a working estimate, not a verified yield for Banz.

For example, if the measured ratio is 6:1:

6 kilograms of fresh flowers would produce approximately 1 kilogram of dried flowers.
30 kilograms of fresh flowers would produce approximately 5 kilograms of dried flowers.
60 kilograms of fresh flowers would produce approximately 10 kilograms of dried flowers.

Actual results must be measured locally.

The correct method is to weigh a batch before drying and weigh it again after it has reached the buyer's required condition.

This conversion is important because international buyers generally purchase dried flowers by weight, not by the weight of fresh flowers collected from the field.

9. International Market Prices for Dried Calendula

Calendula is traded internationally for use in herbal products, botanical ingredients, specialty teas and cosmetics.

However, international prices vary substantially according to product quality, flower type, origin, certification, order size, packaging and delivery terms.

The following examples illustrate the difference between export-market quotations and retail prices.

Indicative international prices

Product and market reference	Advertised or quoted price	Important qualification
Whole dried calendula flowers, Egypt, FOB export quotation reported in 2026	Approximately €0.86/kg	Indicative export benchmark for conventional whole flowers
Dried calendula petals, Egypt, FOB export quotation reported in 2026	Approximately €1.89/kg	Petals attract a higher quoted price than whole flowers in this example
Dried calendula flowers, Egyptian exporter listing	US$8/kg	Advertised price with a stated minimum order of 500 kg
Dried calendula flowers, Chinese supplier listing	US$30–38/kg	Supplier quotation for a particular packaged product; not a general bulk farm price
Dried calendula sold by a UK specialty supplier	From approximately £17.49/kg	Retail or small-wholesale pricing, depending on order size

Sources include the October 2026 market report from Commodity Board, the Freshdi supplier listing, the China Tea Leaf supplier page and the UK retailer Mimea Mauzo.

These figures are not directly comparable. Some are export quotations, while others are supplier or retail asking prices.

For the Egyptian quotations, FOB means the seller's price covers the product up to loading at the named port under the applicable shipping arrangement. It does not mean the buyer receives the product in PNG or that the farmer receives the quoted price.

A PNG farmer should therefore avoid using premium retail prices to estimate farm income.

What price should a PNG farmer expect?

There is currently no verified, established PNG farmgate buying price for calendula available in this assessment.

It would be misleading to promise that international buyers will pay a particular amount for calendula grown in Banz.

The practical approach is to obtain quotations directly from potential buyers and compare their requirements with the cost of producing, drying, testing, packaging and exporting the flowers.

Useful starting references include:

Commodity Board: https://commodity-board.com/egyptian-calendula-prices-edge-higher-on-firm-export-demand
Freshdi dried calendula listing: https://freshdi.com/product/Dried-Calendula-flower
Mimea Mauzo dried calendula petals: https://www.mimea.co.uk/product/marigold-petals-whole/

These are market references, not confirmed buyers of PNG-grown calendula.

10. Is There a Local Market for Calendula in PNG?

The local market needs to be investigated before commercial production begins.

Potential customers to approach include:

Florists and ornamental plant sellers.
Plant nurseries and garden centres.
Herbal-product businesses.
Soap and skincare makers.
Specialty tea businesses.
Craft businesses and gift shops.
Agricultural and horticultural organisations.

These are prospective market segments. Their demand for calendula in PNG has not been confirmed.

Selling fresh flowers locally

Fresh calendula flowers could be sold as decorative flowers or to customers interested in edible flower petals, provided the flowers are correctly identified and grown for food use.

Potential customers may include restaurants, event decorators, florists and individuals purchasing flowers for gardens.

However, the local demand and selling price must be established through direct enquiries.

Selling dried flowers locally

Small, properly packaged quantities could be offered to suitable herbal-product businesses, craft makers or skincare formulators.

Before selling dried flowers for food, tea or cosmetic applications, confirm the relevant product-safety and labelling requirements.

Selling ornamental seedlings

Growing calendula seedlings for resale may be another business opportunity.

Customers could include homeowners, schools, churches, offices, landscaping contractors and other institutions interested in flowering gardens.

This option may be easier to test than exporting dried flowers because it does not initially require a large dried-product inventory or international freight.

11. Calendula Seed Production and Seed Sales

Seed production could help reduce the cost of maintaining a calendula farm and potentially create another source of income.

Calendula seeds develop after the flowers mature.

How to collect seeds

Select healthy plants with desirable flower characteristics.
Leave some flowers on the plants instead of harvesting every flower.
Allow the flower heads to mature and dry naturally on the plant where conditions permit.
Inspect the mature seed heads and collect the seeds when they are ready.
Remove unwanted plant material.
Dry the collected seeds further if necessary.
Store them in clean, dry, labelled containers.

Keep records of the variety, harvest date and seed batch. For commercial seed sales, germination testing and correct labelling are important.

How can calendula seeds be sold?

Possible sales channels include:

Home gardeners.
Schools and educational institutions.
Plant nurseries.
Landscaping businesses.
Community gardening projects.
Smallholder farmers interested in flower production.

Seed sales will depend on demand, seed quality, germination and the availability of competing varieties.

Estimated seed prices

As a reference, Australian supplier Eden Seeds has listed a packet of 75 calendula seeds for A$3.90 and a 10-gram pack for A$7.00.

Another Australian supplier, The Seed Collection, has listed a 25-seed packet for A$1.50.

These are overseas retail prices, not PNG wholesale prices or guaranteed selling prices for seeds produced in Banz.

They demonstrate that calendula seeds are sold as a gardening product, but a PNG grower must investigate local demand and production costs before setting prices.

For seed sales in PNG, first establish whether local gardeners and nurseries want the product. If selling seeds commercially, confirm the applicable seed-quality, labelling and regulatory requirements.

12. Where Can Farmers Obtain Calendula Seeds in PNG?

Farmers in Lae can begin by contacting agricultural suppliers such as Chemica.

Chemica supplies vegetable, fruit, herb and flower seeds through its PNG branches. However, its current availability of Calendula officinalis seeds must be confirmed directly.

Farmers should ask for:

Calendula officinalis — Pot Marigold

The correct botanical name helps prevent confusion with other marigold varieties.

Chemica's seed catalogue and branch contacts are available at:

https://chemica.biz/seeds

Do not import seeds from overseas without first checking the applicable PNG import permit and biosecurity requirements.

13. Developing Calendula-Based Skincare Products

Calendula flowers are used as botanical ingredients in skincare products.

Possible products include:

Calendula-infused oil.
Botanical balms.
Creams and lotions.
Soap and other personal-care products.

For a farmer, selling clean, dried flowers to an established manufacturer may be a more practical starting point than immediately manufacturing finished skincare products.

Producing and selling cosmetics requires appropriate formulation, hygiene, stability testing, packaging, labelling and compliance with applicable regulations.

Avoid making unsupported medical claims about calendula products. The fact that a plant is traditionally used in skincare does not mean that every preparation is clinically proven to treat a disease.

14. A Simple Calendula Farming Business Plan for Banz

A sensible way to begin is with a small trial.

Phase One: Establish a trial plot

Obtain a small packet of correctly identified seeds.

Prepare a sunny, well-drained growing area and plant a manageable number of seedlings.

The first objective is to determine whether calendula grows well in the local climate.

Phase Two: Measure production

Record:

Germination rate.
Plant survival.
Days until first flowering.
Number of flowers harvested.
Fresh flower weight.
Dried flower weight.
Labour required.
Seed production.

These figures will provide the foundation for a realistic production budget.

Phase Three: Test local sales

Approach local nurseries, florists, gardeners and businesses that might use dried flowers.

Ask whether they are interested in fresh flowers, dried flowers, seedlings or seeds.

Obtain actual prices and estimated purchase quantities rather than assuming a market exists.

Phase Four: Approach international buyers

Contact companies that trade dried calendula flowers and petals.

Ask for written information about:

Minimum order quantity.
Required product grade.
Whole flowers versus separated petals.
Moisture specifications.
Microbiological and pesticide-residue requirements.
Packaging standards.
Sample evaluation.
Price and delivery terms.
Payment arrangements.
Required export and import documents.

Do not plant a large commercial field based solely on online asking prices.

Phase Five: Expand only when the figures support it

After completing a trial harvest and confirming buyer interest, calculate the amount of land needed to meet a realistic order.

Expand gradually and retain sufficient seed for future planting.

15. How to Calculate Potential Profit

The correct calculation is:

Gross sales = kilograms of saleable dried calendula × confirmed selling price per kilogram.

Then:

Estimated profit = gross sales − all production, processing, packaging, transport, testing and marketing costs.

For illustration only, suppose a farm produces 20 kilograms of dried calendula and receives a confirmed price of K10 per kilogram.

Gross sales would be K200.

If the total cost of producing and selling that quantity were K120, the remaining amount would be K80 before any other uncounted expenses.

This is a hypothetical calculation, not a forecast of calendula prices or yields in PNG.

For commercial planning, use actual harvest weights, actual expenses and written buyer quotations.

16. Risks to Consider

Calendula farming has several risks.

Climate risk: Heavy rainfall and poor drainage may damage plants and flowers.

Quality risk: Poor drying or storage can cause mould, colour loss and rejection by buyers.

Market risk: International prices may be lower than expected, and buyers may require quantities that small farms cannot initially supply.

Transport risk: Exporting a small quantity may cost too much per kilogram.

Seed risk: Purchased seeds may be unsuitable for local conditions or may have poor germination.

Financial risk: Retail prices are not the same as farmgate or export prices.

The best way to manage these risks is to begin with a small trial, keep detailed records and confirm market demand before expanding.

Conclusion

Calendula farming offers several possibilities for PNG farmers, including ornamental gardens, dried flower production, seed collection and supplying botanical ingredients for skincare products.

For farmers in Banz, Jiwaka Province, the first priority should be to test the plant under local conditions and establish whether it can produce good-quality flowers consistently.

International suppliers advertise calendula at a wide range of prices, but those quotations do not establish what a PNG farmer can earn. Local demand, product quality, processing costs and transport will determine whether the project is commercially viable.

A careful trial can help farmers learn how to grow calendula, measure yields, collect seeds and identify suitable buyers before making a larger investment.

Start small, measure carefully, confirm your market and expand when the business figures make sense.
