Hi there, I'm very concerned because I love my walleriana hanging basket and some of the leaves have progressively been looking worse recently with a sandy appearance developing on the top of the leaves only. I can't seem to find anywhere on the internet this exact issue. I don't think its a mildew because it doesn't wipe off and it's only on the top of the leaves. It's also not really white but brown/yellow... What am I doing wrong?
That is, classic, spider mite damage, unfortunately! This will take some diligence to get rid of. Here are some articles that will help:
The thin plastic that holds the plant?
I wouldn't. The roots need to be able to grow beyond the confines of the small, plastic containers they are purchased in. If you want to overwinter them, transfer them to a larger pot with good potting soil before sinking them into the ground for summer. Impatiens will do well in a proper sized container on the patio or planted in the ground without a container.
My impatiens are a bit tall and was just wondering if i should trim before I transplant or after
I would not, unless they are not showing any signs of flowering. Generally, tall plants will indicate that there was a lack of light during the growth phase.
If they are not showing buds at all, then it may be safe to prune them lightly.
Here is an article that will help you with their care:
i i love impatients at my front door but i don't know about sun..leaves re yellowish and sort of thick and crackly
They can withstand "part sun", if you acclimate the plant slowly to higher sunlight levels in the space of a week or so. To avoid yellow leaves, keep the soil as evenly moist as you can but never dry. To avoid fungal diseases that can yellow out leaves, do not let the soil get soggy either. So for example, do not water the soil if it is already moist but do consider the forecast in case it will be extremely hot and windy.
I have 2 pots of Impatience (Busy Lizzie's) one is flourishing, the other failing badly? I have fed on regular basis and added slug pellets etc. It "appears" that "something" is living and eating the petals? Any ideas??
Unfortunately, your photos did not come through. I am unable to assess the situation. You may try an insecticide. These articles will help:
I have several impatiens in my garden bed. Some are doing very well, some not. I am wondering why. I frequently sprinkle dolomite on my plants (clayish soil)... I have cut the stems of the two sickly impatiens and applied liquid Powerfeed (fish fertilizer)..see photo Any suggestion? Otherwise will buy more plants to replace those two...
Did you check for insects? It's possible they missed your other plants. Too much nitrogen in the fertilizer can slow or stop flowering.
Does your cat do her toileting near those plants? Or possibly roll on them or dig?
While driving home with flats of impatience some got damaged and broke off even with the top of the root ball. Can I still plant them… will they still grow?
Most of them should. Go ahead and plant them.
