Q: I simply purchased a cherry tree and located it has pink shiny spots on most of its leaf stems. I sprayed with a fungicide however see no end result, these spots look everlasting. Are they OK? Is there some remedy I ought to do?
A: Scale bugs are generally discovered on stems and younger branches of fruit timber. Delicate infestations are normally not an issue. If the tree seems in any other case wholesome, I might take a “wait and see” strategy. Hold an eye fixed out for the presence of honeydew (a sticky substance exuded by scales and aphids) and ant exercise.
Scales are just like aphids in that they’ve a symbiotic relationship with ants. They suck the juice out of a plant and poop out sticky honeydew, which is sort of pure sugar. Ants harvest the honeydew and, in return, defend the aphids/scales from predators. When you can exclude ants from an infested plant, many predatory bugs will handle the pests.
Scale can be a favourite goal of parasitic wasps. In case you have a good-quality magnifying glass, chances are you’ll spot some holes or hollowed out scales nonetheless caught to your tree. Parasitic wasps are tiny and innocent to people, however they will hold scale populations beneath management in their very own, brutal approach.
In case your tree is exhibiting indicators of misery, corresponding to leaf yellowing, and has an out-of-control scale downside, software of horticultural oil ought to management them. Horticultural oil may be very particular to scale and aphids, and shouldn’t hurt helpful bugs. At all times observe package deal instructions and precautions!
Q: Now we have been having bother rising giant container vegetation close to our pool deck. The pots are very huge – 26 inches tall and 28 inches broad. They’re heavy glazed pottery and so they have drainage holes on the backside. All the pieces we’ve tried to develop has died. There have been mushrooms rising in one of many pots.
A: A lot of the giant, heavy, glazed pottery containers have a single drainage gap on the backside. This gap is normally 1 to 1-and-a-half inches in diameter and must be enough for drainage functions. The issue is that because the pot is so huge and heavy, water can not escape freely from the underside of the container whether it is sitting on a tough floor like a pool deck.
The container must be elevated (even a little bit) in order that extra water can drain away. You should buy little toes particularly made for this objective, or you need to use 2 bricks to raise the pot just a few inches.
This may end up in dust leaking out of the underside of the pot. If this turns into an issue, you possibly can take away the plant and potting soil and place a chunk of shade fabric or window display screen within the backside of the pot and exchange the soil and plant.
