I recently bought a cherry tree called Kanzan. Holes have appeared in some of the leaves and other leaves have turned brown around the edges. Could this tree be diseased or is there a bug attacking it?
One of our Photinina Red Robin- X Fraseri, has two or three unusual growths at the base of the branches as they go into the soil. Look like 'barnacles' but quite big about half a tennis ball size. They are 'stuck' to the brances and when we try to pull off no luck at all. The plant itself is ok does not show any sign of growth retardation. We have several of the same shrub on our boundary and no others are affected at all.
A neighbour sprayed his grass verges on our boundary fence line with result we lost 2 perennials and our Joseph Rock Rowan tree was just bursting into leaf all healthy buds prior to the spraying. Result is that our tree has basically stopped growing the leaves and some buds have died, a few leaves have remained 'in limbo' so to speak. Is there any hope for the tree or will we have to replace it?
What do you recommend for killing widespread convolvolus without damaging plants it is growing on? Will Roundup work?
You have touched on mustard as a green manure. Are there others and which best for a veg garden in your opinion?
Can you recommend a variety of Florence fennel that will form proper bulbs instead of long thin leaf bases?
