Welcome to An Hour in the garden no 80First of all, so sorry for last week. (Grandchildren + bug = wiped out!)I finally got into thegarden and harvested cabbages and potatoes and spent the ‘recovery’ time watching the leaves falling, so we do into a little about how and why leaves fall - after all, it can’t just be the wind, it gets windy in the Summer too and the leaves don’t fall at all.The thing is, for many reasons, a layer of cork appears at the end of the leaf, which is more brittle, and so consequently, the leaf eventually falls off under pressure.Quite why is a different story. Many explanations are given, but they don’t always fit the bill, and it seems to me there are combinations of reasons for the effect.We go on to look at some plants I am buying this autumnBroadbean:Aquadulce for sowing nowOscar and Robin Hood for laterCabbage:Getting plants of Aprio, Wheelers Imperial and Winter GreenPlus Savoy for next year, though this year I have been sowing All Year RoundCarrot:Aron F1, Berlicum and and FlyawayCauliflower:You can’t beat the old favourite All Year RoundCelery:Golden Self BlanchingGarlicBohemian Rose Wight from PragueCarcasonne Wight - lovely flavourCaulk Wight - pink striped from RussiaTwo old favourites:Early Purple Wight and Solent Wight
