Varieties of French marigolds (Tagetes patula), that suppress nematodes include ‘Nema-Gone’, ‘Golden Guardian’, ‘Petite Blanc’, […]

Question from Cindy: We are replacing some of our older roses and thought I’d ask your opinion on specific ones to buy! My thrust is fragrance and length of stem to use in arrangements (not floribunda.) I’m interested in fluted edges perhaps, I love a cabbage type of rose …. and really any color other […]

Question from Gayleen: There are a couple of palm trees growing in my patio on their own. I did not plant them. I know nothing about gardening, planting, etc. They have been thriving on their own without any care. Now I have received a letter from my homeowner’s association stating that I must remove them […]

Question from Robin: Was reading in your So. Cal. Organic Gardening about Wisteria. You mentioned cutting unwanted young shoots down to two buds from May onward. Is it to late to trim them now? I know Wisteria is a light feeder but yours look so glorious! Is it the soil and feeding regime or happy […]
