Q. I have always heard that garlic planted near roses will deter aphids. Since we live in the Garlic Capital of the World, it only seems right that I plant garlic. Why not kill two birds and plant garlic next to my roses?
A. I've been maintaining the same thing about garlic for years and definitely go ahead and plant some next to your roses. But the fact of the matter is, there is very little hard evidence to support the idea of plants repelling insects, although there is plenty of folklore around. That said, many gardeners, me included, swear that certain plants do have an effect on insects. Besides garlic and onions near roses, it's said that ants will avoid the mint family and marigolds will reduce nematodes in the soil. Basically, I'm for anything that will help reduce the garden pest population without having to spray chemical insecticides. Go for it!
Q. I have hundreds of sweet alyssum volunteers coming up throughout my garden. Is there any reason it should not be used near my vegetable garden? They seem to attract a lot of beneficial insects. A. First of all, let me congratulate you for noticing that sweet alyssum does indeed attract beneficial insects, including ladybugs (lady bird beetles). Go right ahead and transplant those alyssum volunteers throughout your garden. This tidy, low-growing annual will cover your ground in clumps of white, pink or purple flowers and has the added attraction of a sweet, honey scent. Your biggest problem may be digging up and discarding too many volunteers that spread in your garden. Q. Our carrot seeds never seem to germinate even though we follow the planting instructions explicitly. What are we doing wrong? A. A crust will frequently form over the top layer of soil, making it impossible for the fine carrot seeds to break through. A trick is to mix radish seeds along with yur carrot seeds when you sow. Radishes germinate faster and they'll push through the soil, forging the way for the slower-germinating carrot seeds. Within three or four weeks, the radishes will be ready to harvest. You can pull any before that time if they are crowding the young carrots. Go To Page: 1
