Help identify Discovery Tree problem
Cat 3 Posts: 107
i would appreciate if some one could help with my recent tree purchase of a discovery Apple. I noticed some grey powdery scales on the lower branches I managed to scrape these off but I also noticed that the whole tree trunk is covered in white patches a bit like impetigo. What do I need to do?
It looks very much like lichen in which case there is absolutely nothing to worry about whatsoever. Lichen only grows where the air is very clean.
Thank you. Is it the same for the tree trunk? Should I give the tree some sulphide of potash
Sulphide of potash will help the tree to fruit once it is established but I wouldn't give it any yet. What I would recommend is to widen the ring of removed grass around the trunk so that it is about 1 metre diameter. Grass will compete with the tree for food and leaving an area clear of grass and other plants will help the tree to establish a good root system. You could mulch that area with well-rotted manure (leave a few cm gap near the trunk though) and cover with bark chippings to prevent the grass recolonising the area. Spring bulbs could also be planted if you like as those do their growing while the tree is dormant.
I will remove the grass. Thank you,
