What Happens to Trees During the Summer?

In previous posts, we’ve discussed what happens to trees during the Fall, Winter, and Spring but what about the Summertime? Let’s take a look.

Late Spring

Spring until to June: this is a period of growth

During this time, trees have their most intense growth phase, both in regards to their primary growth and their secondary growth. Wound reaction is best at this time of the year.

EARLY SUMMER

July, end of primary growth

During this time, the tendency of many trees to form new shoots and leaves is slowing down, and often completely stops. The volume of newly formed cells from secondary growth is also reduced, and there is less increase, which can be easily recognized in the growth rings.

SUMMER AND LATE SUMMER

August to September, maturity and stockpiling for Fall & winter

The major development phase is over. Trees have reduced their growth, some of them have even completely stopped and fruit is ripening; this does not require much energy (assimilates). The major part of assimilates produced in the leaves is used to create a winter stockpile as during the cold season, the tree has to live on what it has stored.
