Remove downward growth, growth in the crotches of branches, small yellow foliage, and on pines all needles more than one year old. Wait until next month before rewiring your deciduous trees. However, there are two times a year when you can make major cuts in your deciduous trees without having major problems with bleeding. One time is the day of repotting when root pruning reduces the flow of fluids from the roots. The other time is while trees are still dormant.
Spring is icumen in.
