Pomegranate Houseplants – How To Grow Pomegranates Inside


By: Mary H. Dyer, Credentialed Garden Writer

If you think that pomegranate trees are exotic specimens that require a specialized environment and an expert’s touch, you may be surprised that growing pomegranate trees indoors is actually relatively easy. In fact, indoor pomegranate trees actually make great houseplants. Some gardeners enjoy growing pomegranate bonsai, which are simply miniature forms of natural trees. Read on to learn more about how to grow pomegranates inside, and specifics about indoor pomegranate care.

How to Grow Pomegranates Inside

Pomegranate trees reach mature heights of up to 30 feet (9 m.), which makes them too tall for most home environments. You can get around the size problem when growing pomegranate houseplants by planting a dwarf pomegranate tree, which reaches heights and widths of 2 to 4 feet (0.5-1 m.). Many people grow dwarf pomegranates strictly as ornamental trees because the small, sour fruits are loaded with seeds.

Plant your pomegranate tree in a sturdy pot with a diameter of about 12 to 14 inches (30-35 cm.). Fill the pot with a lightweight commercial potting mix.

Place the tree in a sunny spot; pomegranate needs as much sunlight as possible. Normal room temperatures are fine.

Indoor Pomegranate Care

Water your pomegranate tree frequently enough to keep the soil moist but not soggy. Water deeply until water drips through the drainage hole, then let the soil dry slightly before watering again. Never allow the soil to become bone dry.

Feed your pomegranate tree every other week during spring and summer, using an all-purpose liquid fertilizer diluted to half strength.

Repot the pomegranate to a pot just one size larger when the plant becomes slightly rootbound, but not before.

Prune your pomegranate tree in early spring. Remove any dead growth and trim just enough to remove wayward growth and maintain the desired shape. Pinch the tips of new growth occasionally to encourage a full, compact plant.

Indoor Pomegranate Trees in Winter

Pomegranate houseplants need at least four to six hours of bright light every day. If you can’t provide this naturally, you may need to supplement available light with grow lights or fluorescent bulbs.

If the winter air in your home is dry, place the pot on a tray of wet pebbles, but be sure the bottom of the pot isn’t actually standing in the water. Keep the soil slightly on the dry side and be careful not to overwater the plant during the winter months.

2. Propagating Pomegranate Tree

You propagate pomegranate tree from seeds or from seedlings. The propagation should take place between spring and summer when temperature degrees are about 68 F (20 C). If you are propagating from a seedling, it is recommended that you buy at least 2 years old cutting from your local nursery store.

  • Propagation by Cuttings: You should buy 8 to 10 inch-long cuttings. Plant each cutting in a good quality potting mix. The cutting should be placed in a warm humid place where the temperature degrees are above 20 Celsius. If you live in a hot climate, you can propagate any time in the year but for summer.

  • Propagation by Seeds: To propagate pomegranate tree from seeds, you should buy fully ripe seeds. Clean the seeds from dirt and pulp by rubbing them in a towel. Let them dry for a few days before you sow them. The seeds should be planted at least ¼ inches deep. It is also recommended that you wrap the container with a plastic wrap or place it in a greenhouse so it can maintain adequate temperature for the growth of your seeds. The seeds usually take from one to six weeks to germinate depending on their variety and climate.

3. Choosing a container

You can sow the seeds in a medium-sized pot. However, as your tree grows, you will need to transplant it into a larger pot. For seedling, it is highly like that you will need a large pot. Make sure the ^pot you choose suits the size of your tree and has enough holes to ensure proper drainage.

4. Growth Requirements of Pomegranate Tree

The growth requirements of the pomegranate tree are quite similar to those of citrus trees. These trees are cold hardy and easy to grow in containers. Below you will find everything you need about the growth requirements of the beautiful plant:

  • Location: Since these trees are native to Asia, they are tropical plants that require a lot of sunlight and war. Make sure that you place your pot in the sunniest position. Sunlight exposure is essential for your tree to grow healthy. Although pomegranate grows in a partially shaded location, you should place in a sunny position because the more sun it receives the more fruit it produces.

  • You should avoid using your garden soil because this exotic fruit tree requires loamy, loose, and permeable soil that is rich in nutrients and organic matter.

  • Watering: During the growing season, you should water regularly and deeply. The soil must be kept moist all the time but not waterlogged.

5. Pomegranate Tree Care

  • Fertilizing: All fruit trees are heavy feeder and pomegranate makes no exception. You should fertilize this tree regularly during the growing season. Apply liquid 8-8-8 fertilizer every two-three weeks according to the manufacturer’s instructions. In some cases, your tree will become zinc deficient. You can tell so if the leaves of your plants become yellow. You can cure your plant by spraying diluted zinc solution on foliage.

  • Compost and manure: You should also apply compost and manure. They will help your plant to produce more flowers which in turn means more fruits.

  • Pruning: Pruning is recommended not only because it allows you to take control over your tree’s size and shape but also because it helps your tree produce more flowers and fruits. You should prune your tree between early and mid-spring when the danger of the last frost has passed. Remove all weak, dead and undesirable branches.

  • Repotting: When the roots are bound, that is a sign that you should re-pot your tree. Make sure that you carry out the repotting process when the tree is not bearing any flowers and fruits.

6. Overwintering

To grow pomegranate tree you need to overwinter it. Although this tree is cold hardy, it does not tolerate frost and extreme low-temperature degrees. When the temperature degrees are below freezing, the tree will likely shed it leaves and go dormant. There are some varieties that tolerate freezing temperature degrees though.

When it is too cold outside, make sure to place your tree in a warm place such as a greenhouse, a garage or a basement. The temperature degrees should not fall below 37 F (3 C) otherwise your tree will stop growing.

If you don’t want your tree to go dormant and shed its leaves, you should expose it to at least 4 hours of sunlight and place it in a location where the minimum temperature degrees are at least 7 C (45 F).

7. Diseases and Pests

To grow pomegranate tree, you should learn how to protect it from pests and diseases. As you know, this tree is sturdy and tough, yet it is still prone to many pests such as fruit flies, whiteflies and pomegranate butterflies. For diseases, the most common disease is fruit crack. It is caused by a lack of moisture. Keep your soil always moist and you will manage to avoid this disease.

8. Harvesting

If you are growing pomegranate tree from seeds, your tree will take at least 2 to 3 years to start producing fruits. You can start picking the fruits six months after the appearance of flowers. Simply cut the fruit with your hands or using a scissor or a sharp knife.

This is the best guide to grow pomegranate tree. This guide is provided by experienced gardeners. It will guarantee you a successful growth.


If you’ve grown citrus in a pot, growing pomegranates in a pot cannot 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.

Location

Choose the sunniest location to keep your pomegranate plant happy and healthy. The more sun it will receive, the more it will fruit. However, it also thrives in partial shade, but it makes the plant to bloom and fruit lesser. It is also possible to cultivate pomegranate tree near a windowsill if it receives full sun.

Soil should be loamy, rich in organic content, loose and permeable.

Watering

In the growing period, its water requirement is medium to high. Therefore, it should be watered regularly and deeply. Soil must be kept moist but not wet or waterlogged.

In the winter watering should be reduced.

Pomegranate trees (Punica granatum) are especially suited for growing in containers. The dwarf trees are easier to care for than a full-size tree, while still producing a good harvest of fruit. Full-size trees grow up to 20 feet tall. Dwarf varieties such as "State Fair" grow to be about 5 feet tall and "Nana" is only 2 to 3 feet tall when fully mature. They are suitable for outdoor growing in U.S. Department of Agriculture plant hardiness zones 7b to 10. Bring them indoors for the winter in colder climates. Expect your tree to produce fruit the second or third year after planting.

Allow the soil to dry slightly before watering your pomegranate tree. Water thoroughly, saturating the soil. Allow excess water to draing through the drain holes.

Fertilize the pomegranate tree in November, February and May with an ammonium sulfate fertilizer. Apply approximately 1 ounce per foot of the tree's height around the edge of the pot, keeping the fertilizer away from the trunk.

Prune the tree to remove dead and diseased branches and branches that rub or cross fruit or other branches. Shape the tree to a pleasing size and shape. Remove excess suckers, leaving a few only where you want new branches.

Place the pot in a place that gets direct sun for most of the day. Bring the tree indoors whenever temperatures drop below 40 degrees Fahrenheit. While trees in the ground can withstand temperatures much lower, container-grown trees are more susceptible to cold damage.

Dust the tree with sulfur in June and again in July if mites are present. Control aphids by spraying them with soapy water.

Bring the container indoors in the fall, increasing the time spent indoors by one or two hours daily. Transitioning the tree this way gives it time to adjust to lower light levels. Reverse the process in the spring, bringing it outdoors for a longer period each day.

Check the tree every spring for signs that the roots are becoming pot-bound. Repot the tree in a larger pot before the roots have a chance to out grow the pot. Place 1 inch or more of organic potting mix in the bottom of a pot that is at least 2 inches larger than the original container. Remove the pomegranate from its container and place it in the center of the pot. Fill in with soil around the outside. Tamp the soil down, making sure the trunk remains exposed.
