I have 2 wysteria that I grow over garden arches. They have been in for years and this year, one of them had 4 buds on. However, the buds didn't develop and all of them just fell off. I asked the gardener at the local garden centre what causes it and was told I must not water the plants. I had the same problem last year with a lupin. Does anyone know if this is correct, could stop watering the wysteria but lupin needs water.

If theyre in the ground I wouldn't water them either. Lupins will grow in dry soil, as in my garden and they're huge this year . Wisteria once established need little attention other than pruning as well. The ones I look after get a handful of growmore in early spring and that's it.
Thank you. Difficult not to water them as I have plants growing round, must be more careful. You are quite right, my neighbour has a wonderful wisteria and she never waters anything in her garden !!!
All my lupins are huge and either in bud or flower it is just this pink one that has the problem every year.
Already the buds are falling off and I've sprayed them with a bug killer. The plant looks healthy and full of buds,maybe I should dig it up but would like to know what is happening.
you could try leaving it all alone. Plants don't need extra water unless you're growing something not suited to your soil conditions. Bug sprays

Hi Helen, don't water during the flowering season. Unless we are going throug a longish period of dry weather. From July to September thats the time to water them.. During this time next years buds are forming. If the soil drys out they may abort their flower buds.
Lupins have a large tap root.I wouldn't worry to much about them.
Thank you Musher. It is just the one pink lupin I have trouble with, all the others are flowering well. The plant looks healthy, several flower spikes are fine except the buds fall off before they flower. Just a mystery to me, probably have to dig it up but would love a reason.
