Garden Questions of the Week
“Are Gerbera Daisies and Caladiums deer resistant?“ -Anymore, I’m afraid to mention plants that appear to be deer resistant or low browse, as more and more gardeners disagree and tell us how the deer loved those plants! Anyway, I still like the list put together a few years ago by the Cincinnati Zoo and Botanical Garden – seems to be holding its own. Anyway, yes, both are generally referred to as low browse on the deer list. (Visit our website www.natorp.com for that list.)
“Is there a best time to apply a grub preventer?” -I would say to not apply it before May 15, and anytime thru June and July. In bluegrass lawns, mid to late May helps to control a few other pests as well.
“How often do I need to reapply a pre emergent herbicide to the landscape beds?” -For many pre emergent herbicides applied to landscape beds, they last about 90 days. So reapply at around the 75-80 day marker. For Corn Gluten Meal, it lasts about 45 days, so reapply around 30-40 days.
“I applied a weed killer to the lawn but it didn’t kill the weeds I wanted to get rid of! Now what?” -Make sure you read the label first. Not all weed killers kill all weeds! Although Weed B Gone Max (plus crabgrass) or Bonide’s Weed Beater Ultra cover a lot of weeds in the lawn, they may not list the one you’re trying to kill. Always identify the weed, and then make sure it’s on the label. By the way, if you’ve been getting slower results with Roundup so far, I think the temps just aren’t up there yet for it to work at its usual pace.
“What is the annual that looks like coleus but you use it for sunny locations?” -Don’t forget there are now many selections of coleus that will grow in the sun, but the annual I was talking about is Perilla – Magilla Perilla. Tough, durable, loves the sun but takes some shade, and seems indestructible in the ground or in pots.
“How long do I have to wait before cutting back my daffodils?” -Wait 6-8 weeks after they finish flowering, or until they begin to yellow, whichever comes first. Don’t forget – if they need to be dug and divided or transplanted, that would be a great time to do it. Same applied for spring bulbs growing in pots.
