I have moved to Waterfall in K ZN I have had very little success Previously I lived in ,Ekurhuleni (Edenvale) for many years where we had great success for over 40 years. The plants are attacked a by a voracious bug which looks like a bee. What can I do to eradicate this bug that feeds on the leaves which causes the plant to die and the tubers to rot. is the climate too hot or too wet. My son lives close to Ascot in England and has success with his Rhubarb George

From Iowa state Uni -- US Rhubarb can be transplanted in early spring or early fall (mid-September through early October). Rhubarb does best in fertile, well-drained soils and full sun. The best time to transplant rhubarb is in early spring before growth begins. Carefully dig up the plant with a spade. Large plants may be divided into several sections. Each section should have 2 or 3 buds and a portion of the root system. Transplant each section into the garden with the buds 1 1/2 to 2 inches below the soil surface. Space plants 3 feet apart. Rhubarb also can be successfully transplanted in early fall. Fall planted rhubarb should be mulched with several inches of straw. The mulch provides additional time for the rhubarb plants to get reestablished before the ground freezes.

My 2 y/o rhubarb was growing well, then developed a coppery sheen on the leaves which go brown and papery, the stalks get soft, sag and go yellow. It is in raised area, watered regularly under the leaves, well manured and shaded from excessive summer heat. Any advice would be appreciated. Cathi.Dickinson

I have a small rhubarb patch, 5-6 plants, in soil about 20cm deep, then clay. Plants have remained small (Northern Wollongong) and I wish to revitalise by digging plot deeper, and manuring appropriately. Can you advise which manures best to use? Advice appreciated. John Ryan.

Manures are much the same, just some have a bit more N in them - they range about 2-3% to 6-7% I think. Look up the internet. Just buy a bag from a nursery and mix it in well.

I have a rhubarb plant in a polystyrene box. It is growing well, and the stems are thick, but haven't coloured. Should I move it into shade?

There is two types of rhubarb - green and red. Maybe you have the green variety. For 5-6 years I bought celery seedlings (the label shows a nice bunch of celery). Every year I end up with Italian Parsley or similar). Even from two different nurseries.
