Requirements for Growing Pomegranates in Potsgrowing pomegranate trees in pots_mini

If you’ve grown citrus in pot, growing pomegranates in pot can not be difficult for you. Moreover, pomegranate is more cold hardy and easy to grow. It requires a lot of water and fertilizer. It is also frost sensitive but after all of this care it rewards you with iron rich, fresh juicy fruits.

Pomegranate Tree Care

Application of compost or manure is also beneficial. Take care not to over fertilize it as it can cause the tree to produce lots of foliage and comparatively less flowers.

Overwintering Pomegranate

Overwintering pomegranate is similar to citrus. It is a deciduous tree that worships sun. Most of its species are sensitive to frost. But to low temperatures, the plant has developed a protective mechanism.

It sheds its leaves and become dormant below freezing temperature. There are only a few pomegranate tree varieties that survive really freezing temperatures with more than -10 C without damage.

If the pomegranate is cultivated in a pot in a cold climate below it is important to prune it in the fall. Best place to keep pomegranate plant in winter is the garage or basement that remains warm.

In spring, bring back the plant to a warm and bright place so that it’ll gradually acclimate the climate. A window that is oriented to South is good. Just when the plant show the first sign of growth and forms a few fully developed leaves, you can again start to fertilize it and give more water.
