japanese maple in container

(Question)

Can a small  Japanese maple grow in the large container on the balcony? I have east exposure (morning sun only) and if can, which soil can I use.

(Answer)

Yes you can grow a Japanese maple in a container but there are several things to consider. The first is that because it is a tree you are growing it should be a very large container (at least as wide as the ultimate width of the mature tree). You should also be aware of the weight of this container may not be safe on your balcony.   You don’t say what floor you are on, but this is an important consideration in your choice of plants. You should try to select a variety that is hardy to at least two zones colder than the one you are in. (e.g. choose a plant hardy to zone 4 or lower if you live in a zone 6 area). In the Toronto area (zone 6) this might be a problem because most Japanese maples are only hardy up to zone 6.   This is because the higher up off the ground you are the colder the winter winds are and because of the freeze/thaw cycles that containers inevitable undergo.  An east exposure is however one of the best because in Ontario we often get northwest winter winds which can severely damage plants. You might consider wrapping your tree with burlap in the winter months or if you have access to a garden digging a hole and sinking the pot up to the rim in soil for the winter.  You will find that the Acer palmatum varieties are the ones that have the lowest hardiness rating. Avoid those plants that have deeply dissected leaves as they naturally have a more delicate leaf structure which may not take the wind.

Japanese maples will grow in varying amounts of light from full sun to shade but do best if protected from mid-day sun. The eastern exposure that you have is therefore quite satisfactory for your tree.

You can use a bagged triple mix soil. To find more growing information click on this link
