My hostas are being eaten by something unseen, they have tiny holes on the leaves. What can I add to them to stop this? Thanks.

Possibly slugs? Can you post a picture and post it under the Hosta forum:

Most likely they are being attacked at night by slugs. You can try slug bait and you can try dousing the plants and soil at the base with a mixture of 1 part ammonia-10 parts water. Better yet is to douse the soil area with that mixture in autumn when you do fall clean-up and again in early spring just as the hostas are emerging. For now, I've been known to make evening forays out into the garden with a headlamp and a spray bottle of the ammonia mixture.

I posted the hostas with tiny holes, as well as some healthier ones that are by some shade. Also, there is a Japanese maple tree I had found in my backyard under some azaleas which I replanted up front. Some leaves have white spots. Does this tree need fertilzer? I guess I can look it up but I also wanted to ask you avid gardeners as well. I also added some mulch around the bade, but not too close to the trunk stem itself, I heard that mulch should not be planted too close to trees. Thanks in advance!

It does look like slug damage, re the tree did you have a wet spring? Probable fungal disease which may look unsightly but probably will not hurt the tree. IMHO would not fertilize the tree while it is under stress, plus you said you transplanted them which will stress the tree for awhile.
Sure others can and will weigh in.

I transplanted it in early spring, yes. I guess the next best time to add fertilizer is in the fall then? Thanks so much.

You're right about not putting mulch too close to the tree. You never want to cover up the root flares. Also, if you ever need not want to water the tree, be sure to do it at the drip line. The tree looks small so that shouldn't be much of a concern.

I agree that you shouldn't fertilize the tree while it's stressed out. Not sure if you'd need to fertilize it in the fall. Others can address that. I think a good mulch is all it would need.
