Earlier in the season, around mid-March, I was encouraging you to plant your own onion transplants and grow your own onions. They are so much better tasting than store-bought onions. I gave the readers here and on my blog some varieties to choose from; many are available from seed, which should be started in about mid-October, the same time as you would plant garlic.
Question: I bought a house last December that has two large grape vines growing over a pergola that covers a hot tub. Last summer when the vines were producing grapes, the birds were unbearable.
Q: I have a saguaro cactus with three big arms growing from it leaning toward the west. On the east is my house; it shades the cactus from the morning sun. I also have been watering on the house side of the saguaro, the upslope side, and letting the water run downhill into the roots. I water about three or four times a year and water very slowly.
Question: I found a couple of beans in my garden that have been devoured at the base. Could it be some sort of soil-borne larva or possibly a virus?
Q: I have an African sumac that has sprouts coming up from the roots. Besides trimming them every time they get above the soil level is there anything I can do to stop these sprouts from popping up?
Question: Last fall, I pulled one of my cucumber plants. One of the plants definitely had strange roots, which I am almost positive were caused by root-knot nematodes. Are these nematodes harmful to humans and my dog?
Q: My hybrid Bermuda grass lawn is flat , yet it seems bumpy when I mow. Can I get it as flat and smooth as a putting green? Should I fill these low spots with sand or something else?
Question: What should I be doing for my lawn in March?
Q: Do you know anything about a grass seed called CanadaGreen I saw for sale in a magazine? It says it sprouts and covers the area in 10 days and can survive from 120 F to 40 below zero. Is it any better than selections available at stores here?
Question: I know that the fruit trees at the orchard are spaced closer together than what is normally recommended. With the way that they are pruned, it works out really well.
Question: Can eucalyptus leaves be used for compost or mulch?
Question: I started a new lawn last fall, and I am very happy with the results. I want to reseed the areas that came up a bit thin. When and how should I do that so I don’t damage the rest of it?

Question: What other landscape shrubs benefit from an application of iron chelate? I know bottlebrush and photinia. Others?
