Your questions with answers

Here are a few recent email questions I received with answers.

Disclaimer: There are many products that often work for various yard and garden problems including organic solutions. I can’t list them all here. The products listed are ones that I’ve personally used or know someone else has used and had good results. Always read and follow label directions.

Is it OK or is it harmful to weed the garden after a rain when the ground is soft?

It is really not good to be walking on the soil when it is moist as this leads to soil compaction, which can make it harder for plants to grow. If you are just reaching in and pulling the weeds from say your lawn or a path that it is fine.

I saw you on KSTP TV talking about killing crabgrass. You mentioned something about corn gluten. What is it I need to get to kill crabgrass that is already growing?

Corn gluten prevents crabgrass from germinating and is put on right now. Crabgrass that is growing already can be treated with Bayer Crabgrass Killer or Ortho Weed B Gon Max plus Crabgrass.

Help!! My trees are lumpy. Two summers ago I noticed small lumps or warts on the leaves of two of my trees. Last year they were on a few more trees and covered the whole tree. There were so many of these "lumps" on the leaves that most of them became a curled up balls. They did not die, but they look rather unsightly and I think it will stunt new growth. I fear this year it may continue to spread to more of my trees. I am not sure if it is a disease, fungus, insect or a harmless part of nature. If there is something I can do to treat or prevent this please let me know.

It is a plant gall. It does not hurt the plant at all, it's just part of nature. Treatments are mostly ineffective and since it does no harm, why bother.

How do we get rid of voles in our backyard? Not moles but voles.

Molemax Mole and Vole Repellent is probably the best thing to try.

What is the best way to keep the deer and rabbits out of my garden?

Both are very difficult if not sometimes impossible to keep out. Fencing with very small holes in it can help with the rabbits. A few products that will help with the deer include:
Liquid Fence
Shotgun Deer and Rabbit Repellent
Repellex Deer and Rabbit Repellent

Everywhere I have hostas I have moss all over the ground, how can I get rid of the moss without killing the hostas and other plants and flowers?

Personally, I love moss in the garden. The only place I don't like it is on walkways or stepping-stones because it gets slippery. Bonide Moss Max can be used to treat it. Even with treatment it will keep coming back if you don't change the conditions. You can't change the shade or usually the moisture that moss thrives on. Since it also likes acidic soil conditions, adding some lime to the soil and making it more alkaline may (I emphasize may) keep it from growing back.
