Japanese Weeping Willow Bonsai Tree Care Sheet

General Description:

The Japanese Weeping Willow Bonsai Tree from our wholesale nursery is known for its branches that droop downward from the trunk in a graceful and flowing manner. They are usually cultivated in Japan, but originally native to China and in the wild can grow up to 70 feet tall! These trees are exceptionally easy to maintain, and with its unique look and hanging branches they are sure to impress everyone who gazes at them. Because they are deciduous, they will shed their leaves during the winter, allowing you to fully appreciate the gracefully “drooped” branches. During the spring and summer, the tree will bud leaves that are vivid green and have a feathery effect to them when blown in the wind.

These trees love the sun! Keep your tree in a location with full sun during the day where it will grow and thrive.


In nature, Japanese Weeping Willows are usually found near ponds or river, so they like water. They are slightly drought tolerant, but you should not allow the soil to completely dry out. If you overwater or underwater your bonsai, the leaves will be droopy and most likely yellowish. When you properly water, the leaves will be healthy looking and crisp. Keep in mind that since these trees love the sun, the soil will be prone to dry out quickly if you live in a hot area, so be sure to check daily to see if you need to water it so it stays moist.


The Japanese Weeping Willow Bonsai Tree should be kept outside and because it is a deciduous bonsai, it needs to enter its natural dormant period during the winter. With that said, do not allow the roots to freeze. When the temperatures outside begin to dip be 40 degrees, you should move the bonsai into your garage where it will be protected from frost. Also, keep in mind that during the winter it will loose its leaves. Do not panic! This is normal and your tree is not dead! Once spring rolls around, it will bud and produce the green, flowy foliage yet again.


Weeping willows are different than most trees and do not respond well to being fertilized often. We recommend that you fertilizer only once every two months from spring to summer with an organic fertilizer.


Trim away any leaves that wither during growing season, which will promote more healthy growth as long as the overall health of the bonsai is good. We do not recommend that you trying wiring this tree, as the branches are incredibly delicate and can easily break. Plus, the tree will naturally grow to its “weeping” state, which is the desired style for this particular species.

Potential Pests:

There are a few pests that are relatively common to the Japanese Weeping Willow, so you need to be on the lookout for the following:

Caterpillars are actually quite common and can be incredibly destructive to your bonsai by eating holes in the leaves and continually eating new growth. They usually have fantastic camouflage and can be very hard to see without looking closely. So, if you notice holes in your leaves and suspect it is being caused by caterpillars, it is best to feel the foliage with your fingers to remove them by hand. Insecticides can be used, but overall we have found them to be ineffective. It is best to remove them by hand.

Scale Insects like to attach themselves to the outer bark of the bonsai tree and suck the sap from the inside. They have brown shell and are best removed by hand as most insecticides cannot penetrate their shell.

Aphids can be removed by cleaning the tree and leaves thoroughly with a solution of 1 quart warm water and 1 tsp dish soap.

*Always remember that bonsai trees will be much more resistant to pests if they are healthy in the first place!


We recommend that you repot your bonsai tree in the early spring every two years, while weather conditions are still cool and pleasant. Replace the soil with a well draining soil, and be sure to light pack the soil around the pot to help rid the possibility of air pockets, which could potentially lead to the roots drying out.

Helpful Comments:

As always, from time to time wipe the beautiful leaves of the Japanese Weeping Willow down so that they are free from dust, which will help promote proper photosynthesis and cell health. If you are interested in more information, please read about bonsai tree health.
