A: Not much can be done except to wait until the plants have used any excess nutrients in the soil. Eventually they will flower and you'll have lots of branches with lots of tomatoes on them.
Q: When and how far can you trim kiwi plants back?
Andy Johnson, email
A: They can be pruned much like muscadine grapes are pruned, typically in January or February. But the people I know who have kiwi vines usually let them grow unpruned and huge, if they have the room. This helps ensure some of the vine will survive a very cold winter.
Q: What do you think about using buffalo grass in a front lawn?
Nita Paris, Acworth
A: You can try buffalo grass in a small area but I think you'll be disappointed. This native grass doesn't compete very well with weeds, and the seed takes a while to become established. It turns brown whenever the weather is dry, and it's slow to green up in spring. Habiturf(tm) is a commercial buffalo grass seed mixture you can buy online but it costs $25 per pound.
Q: If goats eat poison ivy is the milk safe to drink?
Mary Boncek, Dacula
A: Goats enjoy poison ivy foliage very much. As happens with dogs and cats, if the goats brush against a vine you can get a rash after petting them. However, a study in California concluded that contact with their milk is safe. As with any life decision, I recommend you drink just a little of the milk first to see if you have a reaction.
