Caring for bonsai trees is becoming more popular with many hobbyists due to how calming yet fun it is. When it comes to boxwood, there are actually a number of types out there: specifically 40. Most of it is a variety of English boxwood (Buxus sempervirens); there’s also B. microphylla or Japanese boxwood, which in itself is also a great bonsai choice. 

The best one of them all, however, is Buxus harlandii. It has cork-like bark that’s fissured and quite attractive. This particular boxwood has leaves that are quite small, too. All of that said, it needs to be brought inside as soon as the temperature is 39 degrees Fahrenheit and below.

Read on to learn more about the best ways to take care of boxwood bonsai:


Pay Attention to Your Bonsai’s Fertilisation

If you’re fertilising weekly, use a liquid fertiliser. If you’re more into doing it on a monthly basis, make use of solid organic fertiliser instead. This is particularly crucial for the growing season. When winter dormancy is at play, make sure that the common boxwood isn’t fertilised.


Pay Attention to Your Bonsai’s Location

Where you put boxwood absolutely makes a difference to its growth and well-being. For the most part, it’s best placed outside in a place that’s semi-shaded or sunny. If you want winter protection for your bonsai, get a cold greenhouse going. Chinese boxwood can go indoors, but it may well be put outside during the summer since that’s where it tends to thrive. In wintertime, the Chinese boxwood needs to stay in a cool room with temperatures at 10 degrees Celsius/50 degrees Fahrenheit with proper lighting.


Pay Attention to Your Bonsai’s Pruning and Wiring

Remember that wires leave marks that will be there for quite some time. Make sure new shoots have a pair of leaves or two left after you prune them. A canopy that’s too dense needs to be addressed so that light can get in. This is best done by leaves being thinned, which helps to promote back-budding. It also has the additional benefit of keeping inner twigs alive. Rather thorough deadwood sculpturing and hard pruning are handled quite well by common boxwood. 

For the wired kind, however, take note that beige bark is delicate. In those cases, when pruning and wiring, you need to take extra care as you go along.


Pay Attention to Your Bonsai’s Watering

The boxwood needs a lot of water during the summertime. However, when short dry periods are unavoidable, boxwoods will be able to withstand those. On the other end of the scale, don’t drown the soil and have it be far too wet either. The key pH value for boxwood is around 7 to 8; that means general tap water can be used as is.



Bonsai trees have been growing in popularity over the years worldwide. There are about 40 types of boxwood out there. However, the most common one is easily English boxwood or Buxus harlandii. To ensure you give them the best possible care, pay attention to your bonsai’s fertilization, watering and location.
