Now is the time that your trees need as much light as possible, and watering can be reduced greatly – weather permitting of course, protect delicate trees from excessive winds though as this could snap the branches.
Junipers and pines can be wired and pruned for shaping. Remove as much moss as possible from your pots as these harbour weed seeds and insects over the winter especially leather-jackets.
Sort your trees out for those to go for what you would like to keep or not the following year and start to think about winter protection of your trees.
This month could give you as much pleasure as in the spring with their leaf colourings before the trees go into dormancy.
