Grape vine

Posted: 13/11/2012 at 01:52

Hi Barbara, It takes a couple of years or more for a vine to become established.  The terrible weather last year also wouldn't have helped - my 40+ year old vine only produced about 10% of what it normally does.  Just make sure you prune them properly by cutting back all side shoots to 2 buds from the main stem (do that in December), keep your fingers crossed that we have reasonably normal weather next year, and I'm sure they''ll start fruiting.  You need patience with grape vines;  They take a few years to get going but after that all you need to do is prune them back each winter.  Pests and diseases are rare. 

Does anyone know what plant this is please?

Yes it's a beautiful plant - I saw it at a stately home I visited.  Does anyone know which type of Delphinium it is please as having seen it I am desperate to buy one!

I would hazard a guess that it is "Leonora", "Pericles" or "Trudy" (probably the latter), all of which are light blue with white eyes.

What is it

There are dozens of courgette varieties with all manner of different coloured and shaped fruit.  I think you probably have a variety called "One Ball", which produces round yellow fruit.  You've left the fruit on too long if it's football sized - pick 'em now and you'll get more, which you should pick when they're about the size of a tennis ball.

Just to clear up any confusion, it can be grown as either group 2 or 3.  Most folk grow it as a group 3, cutting it back hard in early spring, as it is a very vigorous variety.  Grown that way, it flowers in late summer.

Hi Daniel,  The following item is linking to the wrong video - instead of Joe Swift's clip on pruning honeysuckle, it links to Carol Klein's clip on hellebores.  It has come up a number of times in the forum, but I don't think anyone has reported it here:

My money is on squirrels, too.  This thread has reminded me to pick my hazlenuts early this year - last year the squirrels took the lot in one day.  The only ones I got to eat were those I found buried in pots and borders!  They steal enough from the bird feeders over the cold months for me not to feel guilty about them going hungry.

The main differences are in lifetime and safety.  If there are children or anyone who is a bit frail or clumsy about, polycarbonate or safety glass is recommended.  Polycarbonate will eventually become less clear or crazed after over the years, with useful life depending on the quality of the UV stabilization used.  Expect 10 to 20 years.  Standard greenhouse (annealed) glass will stay clear effectively forever, but produces dangerously sharp shards when broken and does become more brittle over time.  Hail can be a problem.  Safety (tempered) glass is much safer, but also more expensive.  If you will be heating the greenhouse, look at multi-wall polycarbonate panels, as they have greatly increased insulation properties over glass (although extremely expensive double-glazed glass panels are available, too.)

I've earmarked this one - though I wasn't going to buy one until (if!) we have moved.  But I see there's a special offer by GW, and I'm so tempted to buy & keep it in a pot until I can plant it out.  Is that a plan?  Or madness?

I suspect the one on offer will be a large plug.  When I buy those, I pot them on anyway so they can grow a good root system before planting, so my advice would be to go for it and pot it up into as deep a pot as you have (I normally use ones with about 5" diameter but about 8" deep.)

Hi Swedboy, you can prune them back quite a bit now.  Here's some advice I posted here a while back which should help:

Hi Beatrice, there's a whole website dedicated to doing just that which may provide some inspiration:
