Normally watering is not required for an established vine because it sends its roots as deep and wide as it needs in order to find moisture. But I have no experience of vines in California or Oz. :-) -- +-------------------------------------------------------+ | Internet: | writing from | | Fidonet: David Rance 2:252/110 | Caversham, | | BBS: telnet://mesnil.demon.co.uk | Reading, UK | +-------------------------------------------------------+ |

My post was a bit sloppy. Can't remember the exact figure off the top, but I think the roots can go down 6 m with no problem. (Or is it 20? anyway, a bit of a dig!) I should have written: sufficient fruit to be commercially viable. In CA and Oz, it is common to use fairly young vines (in the former they are routinely replaced at 20 years) and irrigate for maximum yield; then the juice is concentrated via reverse osmosis, and brewed with oak tea-bags. This all yields a predictable enough result (aside from the headache) at the local Tesco. Still, some irrigation is required in the hot climates to produce enough fruit to bother at all. Just read that growers in Champagne are buying land in the South Downs for vineyards. Apparently it is similar to Champagne (the region) and the cost is about 1%. -E -- Emery Davis You can reply to by removing the well known companies |

(Your vine should be planted outside the greenhouse, BTW, and be guided in, using something soft or which will push aside as the stem grows in diameter.) Having watered profusely, water it again. That's interesting - I'd heard this somewhere before, but no-one was able to tell me 'why' I should plant the vine outside. As we were building a new greenhouse, I figured the ground inside (once you got below the 3 inches of gravel and the anti-weed, water-permeable membrane) was likely to be the same as that outside, and as anything above ground was going to be inside the greenhouse anyway, it probably didn't make much difference. So my vine is planted IN the greenhouse (simply to make it easier to apply water to the root system near the stem/trunk). Is this a major error? In the opinion of most of the pundits, yes. Water tends to drain straight downwards, with only a little sideways wandering, and the soil under a greenhouse is quite soon very dry. Copious watering inside the greenhouse leads to high humidity and an increased risk of moulds. If you can't move the vine, you can persuade the roots to move themselves by watering outside the greenhouse. I'll be installing an auto watering system in the next couple of weeks, can anyone tell me how much water a decent size vine needs. I intend set the system to water twice as day as I do now, but I'm not sure about the amount. At the moment I give the vine a good sized watering can - about 1.5 gals? - at each watering. Is that enough? The plant seems healthy, and no signs of any problems so far. I would say that wasn't enough - depending on the size of the vine. -- Rusty Open the creaking gate to make a horrid.squeak, then lower the foobar. http://www.users.zetnet.co.uk/hi-fi/ |

My grape has just flowered for the first # time. I planted it late last summer so only saw lots of leaves and by # heck it grew fast (1 inch a week). It's growing fast again and now there # are lots of little flowers on it, and I'm crossing my fingers for what # might happen next. I have several hundred vines. I never water the established vines. The crop yield is more dependent on whether we have late frosts or not! Hardly matters if you have a million vines. four gallons of water a day are not enough for a young vine. -- Rusty Open the creaking gate to make a horrid.squeak, then lower the foobar. http://www.users.zetnet.co.uk/hi-fi/ |

Hello Nick et al I wouldn't worry too much about having planted inside the greenhouse. I have two vines (one swee****er, one muscat) both inside. The roots are, however, on the shady side of the greenhouse in the lee of a garage with all the damp, cool soil under that to call its own. They send roots down a long way. I watered generously the first year or two but after that only when the soil looked particularly dry. Planted with roots outside would perhaps save a bit of work but I wouldn't bother relocating. Perhaps put a few roof slates round the root area. I also have a couple of outdoor swee****er vines against a south-facing wall and these get no more water than the rest of the fruit and veg and produce a few kilos each. What vines don't like in my experience is too much damp on the leaves so I prefer watering only at ground level. Best regards from Ray |
