SPRING TO EARLY SUMMER
From about April to June, period of growth
During this time, the trees have their most intense growth phase, both as regards their primary growth and their secondary growth. Wound reaction is best at this time of the year.
EARLY SUMMER
July, end of primary growth, flower buds differentiation to some extent
During this time, the tendency of many trees to form new shoots and leaves is slowing down, and is often completely stopped. 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, period of maturity and stockpiling
The turbulent development phase is over, everything has been sorted out and all goes well. Trees have largely reduced their growth, some of them even completely stopped growing. Fruit – if any – is ripening, just as the branches and buds. This does not require much energy (or assimilates). The major part of assimilates produced in the leaves can be used to create a winter stockpile. In winter, the tree has to live on what it stored. Now is the time to make provisions.
WATERING DURING THE MIDSUMMER
We recommend watering trees at temperatures around 30 °C once a week:
- young trees ca. 100 – 300 liters of water (15 – 40 mins*) and
- old trees ca. 300 – 500 liters of water (40 mins – 1.5 hours*).
