“How do I stop those awful suckers my trees are sending up around the base of the trees?
It is simple. Spray those suckers with Bonide’s ‘Sucker Punch’. One-shot stops them from re-growing for the entire season.
“Can I cut off the foliage of my daffodils?”.
It depends, has it been at least 6 weeks since they stopped flowering? At least 6 weeks or they start to turn yellow, whichever comes first. By the way, that’s also the best time to dig, divide, or transplant spring-flowering bulbs.
“When is the best time to dig and divide perennials when they have gotten too large?”.
Yes, perennial gardens are always on the move. Most can be dig and divided spring or fall, and a general rule is late summer and fall bloomers dig and divide in spring/spring and early summer bloomers dig and divide in late summer/fall. There are exceptions and some that can be moved about anytime if needed…like daylilies! Peonies are late summer. A great reference book is ‘The Well-Tended Perennial Garden by Tracy DiSabato-Aust, Herbaceous Ornamental Plants by Steve Still, and the Herbaceous Perennial Plant books by Allan Armitage (www.allanarmitage.net)
“We have peach leaf curl on the peach tree. What do we spray it with at this stage?”
Thin the fruit and do all you can to keep the tree as healthy as possible. Then, in the fall, when 90% or more of the leaves have fallen, spray with Mancozeb, Fungonil, or Copper. Do it again as buds start to swell in early spring.
“Unfortunately, my shade Impatiens were hit by the Downey mildew last summer. What are my options for replacing them?”
Well, we all know that nothing flowers in a solid shade like shade Impatiens. And for those who didn’t get it last year, I say keep planting. Look at Coleus, Torenia, Caladiums, Wax begonias, Whopper begonias, Non-stop begonias, New Guinea and Sunpatiens (best in the filtered shade), Perilla, Nicotiana, Lobelia, Hypoestes, and don’t forget shade-loving perennials.

“I’ve read about the new blackberries that fruit on the new canes that grow that year. Do you have those?”
Yes, we have Prime Jim! And they actually flower on the first years’ canes, and then again in June. Just like Heritage Red Raspberry. And they flower and fruit for a longer period of time. Very cold hardy, self-pollinating, and are considered everbearing.
