The quick and convenient step by step guide to growing your caper seeds!
Mature caper bushes require dry heat and intense sunlight to flourish, and cannot survive temperatures below 20 degrees F. If you live in an area with harsh winters, plan on bringing your caper plants inside during the winter or just grow them in pots in a greenhouse. Caper seeds are dormant and can be notoriously difficult to germinate. You can also just try planting the seeds, but the following these steps will give the best success (30-45% germination).
How to Grow Caper Seeds!
#1 | Soak your caper seeds in warm water for 24 hours, then place your caper seeds in a wet paper towel and place inside a plastic bag. Leave the bag in the refrigerator for 6-8 weeks.
# 2 | After 6-8 weeks have passed, remove your caper seeds and soak them again in warm water for 24 hours.
#2 | Plant your caper seeds 3/8 inch deep in a mixture of potting soil/perlite/sand (50/25/25%). Keep the mixture evenly moist and plant 5-6 seeds per pot. Seeds should germinate in 3-4 weeks.
#3 | Once your caper seedlings are 3-5" tall choose the strongest plant and cut the rest with a scissors. When transplanting, disturb the root as little as possible.
