Japanese Maple – Acer palmatum: Sunburn Leaves.

Not enough water and sunburnt leaves

Not enough water and sunburnt leaves

Bonsai trees are grown in shallow pots, and because they do not contained a lot amount of soil, they will be easy to get dry especially in hot sunny days. I just repotted all my bonsai early spring this year and all of them were doing well. In the last few weeks, the temperature went up and down and few days reach above 25 deg. C. There were quite a bit of rainfalls that soaked the ground. Because of these rainfalls and only few hot days, I assumed that the bonsai trees would be alright without watering for several days. This assumption had proven to be wrong. It has damaged three Japanese Maple bonsai trees. I should have checked them to see that the soil was not too dry and I should have moved them in shady place.

Before and After the Damage

Before and After the Damage

Well, the damage is done. I stripped most of the dry leaves with the hope that new leaves will eventually grow. They have been moved to shady place with a lot of water to wet the soil. The branches are still green, so the chance of recovery will be high. The sign that maple leaves have sun burn damage is the dry edges of the leaves, especially the exposed outer parts of the foliage.

Ficus Bonsai – Drastic Pruning.

New Leafs on Shorter Branches

New Leafs on Shorter Branches

The largest and the oldest Ficus bonsai (Chinese fig) used to have long and lanky branches with only leaves on the tip/end. These long and bare branches make the bonsai looks less attractive. Early spring this year I dared myself to do a drastic pruning by shorten all the long branches. For some time it was almost completely leafless, but now it has started to grow new leaves all along the branches. The leaves are still small, imagine when they have grown bigger, the once scraggly looking tree will transform into a bushy one. I am quite pleased with the result.
