Tim began by showing 2 plants. The first was a relative of the allium, which has “gone native” and is very invasive. He described it as a Triffid, with its long drooping neck and head. If you find one in your garden cut the seed head off before trying to remove the whole plant and its bulblet.
A much nicer plant is the Peruvian Scilla. Originally from the Mediterranean, it got its name from the SS Peruvian – the ship which first brought it to the UK.

He then went on to describe clematis wilt, which particularly affects the varieties with larger flowers. You should really plant these deep to encourage good roots.
If your clematis does wilt, cut it off at the base, give it plenty of feed and water, and it should recover.

Now is a good time for planting out, and also for moving plants. You should give them a good soak in a bucket of water until the bubbles stop coming up.
If the plant is in a pot and has a dense root system, take it out of the pot before dunking it. And always remember to make a note of where you have put it – don‘t rely on memory!
Tall perenniels need good supports, otherwise they will flop.Or you could do a “Chelsea chop”, i.e. reduce the height by a third during the next 2 weeks, and this will make them more sturdy.

If you see leaf damage on new leaves, it might be from some recent frosts rather than disease. It should grow out.

Finally, it is a good idea to stagger the sowing of your vegetable seeds, particularly lettuce, runner beans and french beans. That way you will extend your picking season. Otherwise you will go from feast to famine!
