Q: I’m trying to ship you an image of my angels trumpet after I took it inside. All of the leaves fell off, and a white mold-looking substance began to type. One trunk placed on new leaves and the “mildew” took over, and now the brand new leaves are falling off. Are you able to give me any recommendation?

A: Wow, that’s a formidable show of what seems to be a scale infestation — an insect that attaches itself to the plant and sucks out the sap. Minimize the plant again on the high the place it’s extra closely coated, throwing away all that you just prune off. Transfer the plant into your storage when you’ve got one. You need to maintain it as cool as potential and not using a onerous freeze. Brugmansia (angels trumpet) can survive gentle freezes, however the plant will freeze to the bottom and are available again from the foundation system. Since you might have moved it indoors, it will not do nicely outdoors now. However inside, in a heat house, the bugs will construct up extra rapidly. On a gentle day, transfer the plant outdoors and spray it with a dormant oil or Neem oil, totally protecting the plant to smother out the bugs. You can even discover houseplant spikes that comprise a fertilizer and an insecticide, which may even assist. Monitor the brand new development to ensure it’s clear.

Temperatures hit document lows in December, and even protecting them did not assist. For now, attempt to ignore it. If you happen to prune now, you expose much more of the plant to potential harm. We’re simply getting began with winter, and who is aware of what we have now to come back? Let’s hope we do not get a repeat of the current brutal chilly, however let all crops keep the best way they’re till spring arrives and we are able to assess what’s useless and what’s burned.

Q: I used to be anticipating to see some harm on my gardenias as a result of I do know they will get harm with chilly climate, however it is best to see my pansies. I’ve by no means had them freeze to loss of life earlier than, they usually look hideous. Even that 12 months we had 15 inches of snow, they pulled by way of. Is there any probability they will come again, or ought to I pull them up now? I’m not going to have any coloration this winter any all.

A: Once more, you aren’t alone. My pansies look fairly ragged too, however some may pull by way of. The flowering kale and cabbage are lengthy gone. We obtained colder than we usually do, plus the chilly lasted for days. Snow is definitely an excellent insulator and guarded the crops, which is why they bounced again.

Q: We purchased a brand new lake home this 12 months, and the earlier house owners planted Bradford pears within the again yard. They’re attractive bushes, however they block our view of the lake. How excessive up can I prune the limbs with out killing them, to permit for a greater sight line to the water? And when ought to I do it?

A: I do know many gardeners love Bradford pear bushes for his or her spring blooms and their crimson fall coloration, however they aren’t a favourite tree of mine, because the birds eat the fruit and drop the seeds all over the place. There are seedling pear bushes blanketing our state now. I’d take away them and plant one thing else. To reply your query, limbing them up is not going to kill the tree, however it may make it structurally unsound and never very aesthetically interesting. Bradford pear bushes are prized for his or her good teardrop form. This form alone causes them to be considerably top-heavy and due to this fact liable to storm harm. Limbing them up would trigger them to be much more top-heavy, and will damage their form, creating an eyesore within the garden.
