Pruning a big leaf maple
The best clock time to prune a big leaf maple is during the abeyant time of year , which is typically late wintertime or early spring before the new maturation begins . This timing minimizes sap loss and allows the tree diagram to heal cursorily .
Before you start rationalise , take a pace back and tax the tree ’s overall shape and bodily structure . Identify any bushed , pathological , or damage branch that need to be remove . Also , look for branches that are crossing or fray against each other , as these can cause wounds that may go to infection .
Remove dead , diseased , or damage branch : begin by removing any dead , diseased , or damaged arm . thin out these branch back to the point where they get together a heavy offset or the trunk . Make the cut just outside the branch collar , which is the slightly swollen domain where the arm receive the automobile trunk or large branch . This collar control chemicals that aid the tree heal the lesion .
Next , thin out the canopy by removing some of the smaller branches grow within the tree ’s interior . This will increase gentle wind circulation and sunlight penetration , which can facilitate reduce the hazard of disease and promote healthy growing .
To defend the tree ’s innate shape , selectively prune branches that are mature out of proportion or detracting from the overall form . Make the cuts just above a healthy bud or sidelong limb .
sucker are small shoots that grow from the floor of the tree , while water sprouts are tight - growing upright offshoot that often initiate from the trunk or independent branches . Remove these undesirable growth by cutting them off as close to their point of origin as potential .
After pruning , clean up the area around the tree by bump off all the pruned branches and debris . Dispose of any diseased or infested cloth to prevent the spreading of disease or pests .
