Upon arrival

Open all cartons/crates immediately after arrival, as the plants need fresh air. Always check plants directly after arrival and take notes of possible problems. If there are any problems, be sure to contact your sales representative immediately. Plants should be planted as soon as possible after arrival. Growers should have greenhouse space, pots and planting medium ready. (Check bottom of confirmation for approximate arrival date). If plants cannot be planted immediately they should be stored in a cool location, preferably at a temperature around 35F. Also make sure that you keep the cartons out of the sun and from too much ventilation, plants dry out very quickly.

Do not store the plants in closed boxes, as this will create condensation and might cause the roots to start rotting. If you detect this problem, make sure you take these plants out of the boxes. You cannot store these roots any longer they have to be potted immediately.

General growing info

After planting a bare-root Papaver in spring, it will take about 6-8 weeks before the plant is ready to be sold. It will take 8-10 weeks after planting for the plant to flower. Soil Papaver prefers a pH range of about 5.5 to 6.2. We suggest using any bark-based, well-drained, commercial soil-less mix.

Planting and Maintenance

We advise using a 2Qt or gallon container.

Plant the crown/eyes at soil level.

Light Conditions

Provide moderate light intensity of 1,500-3,000 foot candles.


Maintain relatively dry conditions, allowing the medium to fully dry between irrigations. Always allow foliage to dry by nightfall to avoid disease.

Fertilization and growth control

Apply at every other irrigation with 75-100ppm of 15-0-15. Height can be controlled by withholding fertilizer.


Grow Papaver at 50-55 degrees F days and 55-60 degrees F nights.
