Warmer weather is on the way, and that means it is time to postpone planting trees. The tree planting deferral season begins May 1st and ends on October 1st.
If you apply for a Tree Removal and Replanting Permit or a Tree Planting Permit after April 30th, your permit will indicate replanting should wait until after October 1st. This is to ensure the new tree will have time to adjust to its new surroundings before focusing its energy on new growth and staying cool.
It may seem strange for Urban Forestry to ask you not to plant trees when the weather is so nice, but there is a good reason! Trees planted during hot, dry weather are less likely to survive. During these warmer months the newly planted tree is working overtime trying to establish itself in its new environment and growing new roots while experiencing limited water. However, in fall, water requirements are lower, rainfall is more abundant, the temperature is cooler and roots grow best in cooler soils. The cooler temperatures allow the trees to focus energy on growing roots and becoming better established prior to spending energy on growing new leaves.
Remember to mark your calendars to plant your new tree beginning October 2nd, 2018!
