Green Mound Juniper Bonsai Care Sheet

General Description:

The Juniper Bonsai Tree from our wholesale nursery represents exactly what people think of when they hear the word “bonsai”. It represents the art of bonsai in a classic sense with the flowing grace of the trunk and branches against the vivid green foliage. The Juniper is a hardy conifer that is one of the easiest to care for. Originating in China, these trees are truly classics. They are slow growing tree that have the ability to live for centuries if properly cared for. Their foliage is dense and compact, and remains a dark green throughout the year.

Juniper Bonsai Trees prefer to get slightly filtered, but constant sunlight, such as a partially shaded area. We recommend that you avoid keeping them in direct sunlight during the heat of the day to avoid having them dry out, but they will grow best in bright, filtered sunlight.


Most likely, you will only need to water your Juniper every couple of days since they prefer to slightly dry out in between watering. We recommend that you check the moisture levels of the soil every day. To do this, gently push your finger into the soil about half an inch. If the soil is wet, wait to water. If the soil is dry – time to water! It is that easy. You do not want to let the tree sit dry for several days though as that can cause damage! As a supplement to watering, it is also a good idea to mist the foliage of the tree with a spray bottle to help create and maintain a humid environment around the tree. Keep in mind that you mist a bonsai in addition to watering, not instead of watering!


One of the most favorable aspects about the Green Mound Juniper Bonsai Tree is that it is very hardy, meaning that it can survive and thrive under many different conditions. These are outdoor trees and thrive in moderate warmth, but we do recommend that you protect the roots from frost during the cold winter by moving them inside your garage where these is still minor protection from the harsh outdoor temperatures. A huge mistake that far too many people make with these trees, and most bonsai trees in general, is that they do not allow the tree to enter its natural dormancy cycle in the winter. If you remove your tree entirely from the cold, it will never go dormant and will undoubtedly have serious problems down the road. Make sure your tree experiences the natural cold, but do not allow the roots to freeze. If you would like to read more about this, please read our article about dormancy.

Some people choose to keep their junipers inside. This can be done, but keep in mind that it is not the best environment for the tree and you could be setting yourself up for problems. They require a lot of sunlight so make sure that it is in a bright, sunny window!


We recommend that you begin to fertilize your Juniper using an organic liquid fertilizer in the early spring, and continue fertilizing every two weeks during the growing season, which is usually from spring to fall. This will help ensure that your tree remains happy and healthy throughout the year.


Green Mound Junipers tend to respond very well to reshaping or wiring – so shape away my friends! We recommend that you only do major trimming in the early spring, just before growing season so that the tree will heal faster. The bark on these trees is usually stiff, so be careful not to break the branches if you are wiring the tree. You can prune throughout the year, but again, only do the major pruning during the spring. If new shoots spring up in a spot that you don’t like, simply pinch them off with your fingers but always be careful not to damage the other branches on the tree.

*Note: Junipers have very prickly needles that irritate most people’s skin, so do yourself a favor and wear gloves if you are closely working among the needles!

We recommend that you repot your juniper every three to five years in the early spring, just before growing season. When trimming the roots, only cut off about 1/3 of the root ball. When you replant the juniper, used a well-draining soil and place it in a semi-shady location for 1 month afterwards to keep the roots from drying out. This allows for the tree to be protected while the new roots begin to grow.

Insects / Pests:

Unfortunately, Junipers tend to be prone to spider mites. Spider mites look like little specks of moving dirt that can suck the nutrients out of the foliage, making them slightly discolored. Spider mites rarely cause severe damage, but you will still want to take care of them if you notice them. It is best to visit a local store and pick up a pesticide that lists spider mites and after a few applications, you should be good to go!

Interesting Facts:
