Houseplants don’t have to be small. There are trees that you can grow in pots indoors. A popular tree to grow as a houseplant is the ficus tree also known as the weeping fig.

What is a Ficus Tree?

There are many plants in the ficus family, which includes fig trees. The weeping fig is a popular one to grow indoors as a houseplant. They are native to Asia where they can grow as high as 50 feet tall. Here in the US, they are only hardy in zones 10 and 11 so most of us have to grow them in containers and bring them indoors in the winter or grow them as houseplants. They make good houseplants because they don’t require direct sunlight. Even if we have sunny windows, our homes are too dark for sun loving plants. The plants we call houseplants are usually shade plants in their native environments. A ficus tree will be happy either in front of a sunny window or in a corner of your room away for the window.

Do Weeping Figs Produce Figs?

Yes, weeping figs will bear fruit if grown outdoors. They will produce flowers which are then pollinated by wasps to produce the figs. The trees never bear fruit when they are grown solely indoors. They rarely flower indoors. When they do flower, there are no wasps to pollinate the flowers so the trees will not bear fruit.

How to Grow a Ficus Tree Indoors

Plant your ficus in a pot with standard potting soil that has perlite or vermiculate added for drainage. Drainage is important. The roots should never sit in soggy soil. They will rot and die. Water it well, until the water is running out of the drainage hole. Wait at least a week for the soil to dry out before you water it again.

If your tree is spending the summer indoors, place it in front of a sunny window. In the winter, move it away from the window to a spot where it will receive light part of the day. Remember to turn your tree every week so that the new growth doesn’t only happen on one side of your tree making it lopsided. You want it to evenly grow on all sides.

Another reason why you want to move your tree away from the window in the winter is the possibility of drafts during cold weather. Weeping figs will die in temperatures below 55⁰F. So it is best to keep your tree away from windows and doors when the outdoor temperatures fall below 55⁰F.

Add a slow release fertilizer to the container at the beginning of the summer when your tree will be actively growing. Do not fertilize it during the winter when it will be resting and not actively growing. Pruning should be done in late winter or early spring before any new growth appears.

How to Move an Indoor Weeping Fig Tree Outdoors For The Summer

You can grow a weeping fig tree outdoors in the summer and indoors during the winter. When moving your tree outdoors in the summer, wait until after your last frost. In my zone 6 NJ garden, I usually wait until Memorial Day at the end of May to move my houseplants and tender perennials outdoors. There is the occasional late frost but more importantly, the days may be warm in May, but the nights can become very cold.

Choose a spot outdoors that is not in direct sunlight. A north-facing location or a place in your yard that gets morning sun and afternoon shade is perfect. While your tree is outdoors, there is the temptation to water it using your hose because it’s more convenient, but that is not what’s best for your tree. Overhead watering encourages disease such as powdery mildew. Use a watering can and water your tree at the roots rather than from overhead which wets the leaves leaving your tree prone to disease.

I start thinking about bringing my plants indoors around Labor Day in September. Years ago, the temperatures would start to drop after that date but with climate change, the days and nights remain warm sometimes through the middle of October. Nevertheless, I start watching the weather forecast closely after Labor Day and when the nighttime temperatures start to dip into the 50s, it’s time for my plants to come inside.

Why do Ficus Trees Drop Their Leaves so Often?

Ficus Trees are very sensitive to their environments. Any change in their environment will cause them to drop their leaves. When you turn the plant so that it will grow evenly, the side now facing away from the sunlight, will drop its leaves. If you over- or under-water your tree, it will drop its leaves. If it is exposed to a draft, it will drop its leaves. When you move it away from a window in the winter, it will drop its leaves. The good news is that once it has adjusted to the change in its environment, it will grow new leaves.

Ficus Trees as Bonsai

Weeping figs have flexible branches when they are young, making them excellent candidates for things like braiding their trunks. There are miniature cultivars that are used in bonsai. Bonsai trees are kept small by pruning both the branches and the roots of the trees. Their unique shapes are created by bending, or “training” as it is known, the branches to create the silhouettes that are favored by bonsai enthusiasts.

How to Grow a Weeping Fig From a Cutting

Since weeping figs don’t readily produce fruit, gardeners propagate their trees through cuttings or air layering.

The most popular method is via cuttings. Choose a young, flexible branch that is not stiff or woody. This is an actively growing branch which will root more readily. Cut off 4 to 5 inches, including the growing tip. Remove the leaves from the bottom 2 inches. Dip the cut end in rooting hormone and push it into the soil up to the first leaves. Be patient. Cuttings made from trees and shrubs take longer to grow roots than cuttings from soft stem plants like flowers and herbs. You will know that new roots have started growing when you see new growth sprouting at the top of your cutting.


How to Propagate a Weeping Fig Using Air Layering

Air layering is more difficult. It should be done in the spring when the plant is actively growing. In this case, you want to use a woody branch that is approximately 12 inches long and ¼ inch thick. Choose a spot in the middle of the branch where there are leaf buds growing. You need the leaf buds because this is where the new roots will grow from. Scrape the leaf buds off, then score the surrounding bark and peel it off. Rub rooting hormone in the bare spot on the branch and wrap it in sphagnum moss which you have moistened ahead of time. Wrap plastic around the branch to hold the moss in place. Secure it at either end. You should see new roots forming within 1 to 2 months.

When the new roots appear, sever the branch from the tree below the plastic. Carefully unwrap the plastic and then just as carefully plant the roots in a container and water well. Congratulations! You have a new weeping fig tree.

Questions & Answers

Question: Is the fruit from the ficus tree safe to eat?

Answer: Yes, the fruit from the ficus tree is safe to eat.

Question: The new growth on my ficus is crinkly. I don't see any black spots or bugs. What is wrong?

Answer: There could be a lot of reasons. Have there been any changes in the plant's environment lately? Fluctuating temperatures could be a cause. Have you moved your plant lately? Changes in the amount of sunlight could be a cause. Have you been watering consistently? Too much or too little water can be a cause. Have you repotted your ficus? Damage to the roots could be a cause. Have the roots grown out of the drainage hole? Dry roots could be a cause. I'm sorry that I can't be more specific without more information on what has been going on with your plant recently.

I'm envious of you. I live up north in NJ where we have to grow many plants indoors.

Interesting information. Thanks for sharing.

I had a couple of ficus trees in my home years ago. They were easy to grow and added beauty to the home. Here in south Florida we see them around the area growing naturally within the landscaping. Thanks for the information on growing them indoors.

Peggy, thanks for sharing that wonderful memory.

We used to have a huge potted ficus tree in our home. It was about 8 feet tall. Years ago when we made a major move to a different state we gave it away to someone who would care for it as we had. It was a beauty! Your writing about this plant reminded me of ours. My hubby used to accuse me of growing so many plants that it looked like a jungle. Ha! Now I primarily grow things outdoors and only have a few plants indoors.
