Dried sprouts on the maple - What to do?
It can hit any maple. Apparently overnight, the hopeful leaf tips and buds are dried up. This guidebook highlights the common causes of shoot damage with tips for problem solving and prevention.
Cold air lake causes the budding to wilt
In spring, gardeners often complain of wilting, dead shoots on the maple. After the first warm sunny days sprout the tender, frost-sensitive leaves and buds. If late ground frosts occur overnight, the fresh shoots have nothing to oppose them. The danger is high until mid-May. After the Eisheiligen the situation relaxes.
Like liquid, the cold flows down into levels and valleys. There are veritable cold air lakes that take leaf and shoot tips in the frosty pliers. The sprouting of sycamore maple and field maple is less affected by frost damage than maple and maple.
Eliminate and prevent damage to the shoot - That's how it works
Damage to fresh maple shoots caused by cold air is not a threat to the existence of the tree. Nevertheless, you should not take the problem lightly. Through the path of frozen leaf tips and buds, diseases and pests find their way into the interior of the tree. How to act properly and prevent another shoot damage:
Are you unsure how far the pruning should go after a shoot damage? Then do the vitality test. Below the last dead buds and leaf tips scratch off the bark a bit. If green tissue appears, you are in the living shoot area where you can fix the scissors. Gray-brown to dark brown fabric indicates the deadwood area.
Potassium fertilization prevents frost damage during sprouting
By the way of a targeted nutrient supply in the autumn you strengthen the winter hardiness of your maple tree. In September, administer a potassium-fortified fertilizer such as comfrey or patent kali. Potassium strengthens the cell walls in the tissue and lowers the freezing point in the cell sap.
Tips
Partial damage from budding in maple trees is caused by a dreaded disease. The pathogens of the Verticillium wilt penetrate through the roots into a maple and clog the supply lanes. The results are partly withered, withered leaves and sagging stems.
