September – Is it cold in here? Or is it me?Aug 20th, 2011 | By admin | Category: Monthly Care
Days are getting cooler but there are still hot days an it is still very dry (except during the state fair downpours!). The average high is 83 degrees; the average low is 56 degrees. The record high is 98 degrees; the record low is 32 degrees. If freezing weather is forecast, put the trees in the ground.
Watering: You may cut back on water depending of the temperature, but do not let them dry out completely.
Fertilizing: Half normal feeding. No nitrogen.
Trimming & Pruning: Long shoots on new bonsai should not be cut off completely, but slightly trimmed and only after shoot has matured. Some trees will go through a last spurt of growth before going dormant. Remove any wire that is cutting in to bark.
Winter Care: A cold frame is recommended for winter storage of bonsai that need a dormant period. An alternative method of winter care is planting the tree directly in the ground after gently removing it from its bonsai pot. A cold frame should be built on the north side of a building.
