Acer Drummondii

We planted an Acer drummondii in our garden about 7 or 8 years ago. During this time we have seen it grow and develop into a lovely tree and have had no problems with it until this year. The leaves have a sticky substance on them, and they (the leaves) are falling off (in the summer time). The tree itself is covered with aphids, greenfly and blackfly. Is this normal? We haven’t noticed anything like this before. Any help, suggestions or advice would be welcome.

No, it is not normal. I would treat the tree with neem oil, which is very effective for most insect pests and should take care of any fungal issues that may arise as well. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm ^[1]
