When is the best time to move my Ascot Spurge plants?
The Spurge Ascot, a type of Euphorbia, Is a very hardy plant. I wouldn't see a problem transplanting at any time. The best time, would be spring, though. Here is an article with more information on the plant: https://www.gardeningknowhow.com/ornamental/cacti-succulents/euphorbia/growing-euphorbia-plants.htm
Should these be cut down at the end of the summer?
There are many types of euphorbia ranging from small succulents to large trees. They all have a different method of care. It would be hard to say without more information. If you could include some pictures, then that would help a bunch.
Why would my plant turn brown at the joints and break off? I live in Alabama and it is planted outside in full sun.
It is very likely that a cold snap will do this. They are only hardy down to 30 degrees, and below that will die off completely. Anything below 50, and the growth will slow down.

here i have euphorbia obesa with root mealybugs i guess. this plant was alright few days ago. could mealybugs do this in such a short time? two weeks ago i moved the plant to more sunny part of the greenhouse,and that was the only change the plant experienced since summer,btw,she was on almost direct sunlight all summer,so she is used to it i guess,and was looking really healthy and not minding the sun. i didn't water it since summer as well.the other obesa that stays right next to it has mealybugs as well but looks quite healthy and not affected at all.so...what's wrong here?
Yes. This could, certainly, be mealy bugs... I would recommend watering with peroxide at half strength, and spraying with neem oil.
This article will give you more information on the mealy but, or scale bug: https://www.gardeningknowhow.com/plant-problems/pests/insects/control-plant-scale.htm
We ordered Gopher Spurge plants last year they did great, but we had a terribly cold winter and i fear they may be dead. How do i know if the plants are dead? I have now way of telling if i should just start again or give the plants a chance to come back. Thanks Denice in Idaho
Growing zone for Gopher Spurge plants is zone 5 - 10. This however is a guideline and with the cold that you mention, that is not the normal for your area; your plants may not have survived.
If you see now new growth over the next few warming weeks, this is likely the case. Make sure you give the roots long enough before handing in the towel. It can take quite a while for roots to send up shoots.
This can depend on how patient you are!
I am redoing the garden of a block of flats on the Umhlanga beach front outside Durban. I have planted a lot of Acalypha (yellow java and sport) plumbago,plectranthus and Felicia. the Felicia leaves are slowly turning brown and dying on half the plants? the acalypha's are in semi shade, is this OK? Plumbago I have had to move and they don't seem to like the move, taking a long time to recover? the plectranthus is in shade and taking a long time to get going? Many thanks Robin
Make sure you are adequately watering the new plantings.
Watering is key to success for your plants.
I have this cactus plant. The entire pot fell and a few individual cactus 'stems' fell out of pot. I stuffed them back in. Please advise. Thanks Liz
Although not a true cactus, it is a very close relative of Euphorbia baioensis. These will root themselves back in no time. Just continue to care for it like you would a cactus, and it will recover and be just fine.
Have care when handling the sap. Most species are relatively harmless, only causing mild irritation to the skin. Some, however, are very toxic, causing burns and breathing issues from inhaling sap particulate. Just make sure that you wash your hands after touching this plant.
