Roots And Cutting Substantial: If this is done the material ex¬cavated from the high ground will be avail¬able to fill the low places and purchase of fill made unnecessary or reduced. Preserve all topsoil and grade in such a way that when the job is finished there is an even layer over the whole area.
So far as humanly possible preserve all valuable trees. Consider this when decid¬ing what contours the ground shall have. Place substantial guards around endan¬gered specimens during bulldozer and
trucking operations. Instruct contractors and operators to exercise all possible care. Then pray for the best.
Scraping soil from over roots and cutting substantial portions off root systems, seri¬ously injures trees and may result in their death. Cutting roots too deeply and too close to the trunk on one side of a tree may weaken its hold so that it is likely to blow down in a storm.
Root cuttings are taken in the dormant season from young, vigorous roots. They are about a pencil thick.
The size of a root cutting depends upon the temperature of the environment it is left to grow in. Generally speaking, the warmer the environment, the quicker the cutting will grow and the smaller it can be. No cutting should, however, be less than I in.
An open-ground cutting should be at least 4in long as it will need to survive for some 16 weeks. A cold frame/cold greenhouse provides a warmer environment, and reformation will occur in about eight weeks; the cuttings need be only just over 2in long. In a warm (65-75°/FI 8-24°C) greenhouse or propagator regeneration time is reduced to four weeks, so root cuttings need be only about I in long.See Also Cutting Crosswise:Mow up and down sleep slopes. Cutting crosswise scalps the ridge and the weight of the mower bearing on its low side is likely to scar the lawn surface. •
For the best results, it is important not just to push a cutting into the compost. Always make a hole in the compost first, using a dibbler of a suitable size, and then plant the prepared cutting in that hole. A dibbler should be approximately the same diameter as the cutting that is to be planted.
On The Other Hand See Force In Cutting:Spot check by untwisting the lay to examine for interior sand that could be chafing the line. Do not use a pressure hose for wash¬ing since that might force in cutting grit.
