Trees coming into leaf
/The swelling of buds and coming into leaf is a chemical driven response to spring, warmer temperatures, longer days. It is not a good indicator as to the health of a tree. The real test is if the tree can support these leaves in the weeks following.
So please do not take a tree coming into leaf as it is doing ok. Especially with newly planted, transplanted and trees that were stressed last year, these should receive aftercare, primarily watering.
Whilst a newly planting/transplanted tree is extending a root system to that a of a natural tree, it will need assistance. This can be for upto 5 years as per BS8545:2014
