I have a 40 year old grape vine in a conservatory that I have been maintaining for many years. It is rooted externally and i don't feed it or water it. In recent years crops of fruit have been quite small compared to prior years. I wonder if a new vegetable patch behind the conservatory may have taken some of its root area. There are concrete paths all around the conservatory and earth pits inside where it is planted. Should I feed or water it?

I have three vines in the greenhouse in pots, all growing well but they are not bearing any flower stems at all. This is their second year, and I was told that maybe there is a problem with the soil ph what is the best fertiliser to use to give the vines the right conditions to produce flowers? The varieties I have are Bianca, Rembrandt, and Boskoop glory. Thanks
Hi Gerry, My wife just gave me a Vitis Boskoop Glory grapevine, that she bought in Avoca. I have recently built a greenhouse, that has a very sunny aspect - someone suggested to grow the grapevine outdoors, but to possibly trail the vine into the greenhouse for a higher yield of grapes. Have you any suggestions on the best place to plant this type of grapevine, and is the greenhouse idea worth doing?

Hello Gerry,I was given a present of a vine about two and a half years ago. I was told to put the root outside the greenhouse and bring the rest of the plant inside. This I did. How long will it take before I can get fruit from it? Has there been an article in the IRISH GARDEN? I have almost every issue since it first came out.Dick Roche
hi,gerry,i planted a blackhamburg 25 yrs ago in a unheated green house.i traned it as single rod.the rod developed to 25 ft and produced about 30 bunches of lovely grapes.but for the last three years it has produced no flowers or fruit but plenty of lush foliage, I did all the necessary nipping out each fruiting stem is based 1 ft apart. The rod is planted in a 3ft square. Can I get it to fruit or is the vine exhausted? Its a very mature vine and I would be reluctant to loose it. Hoping you can help. Blackburg,
