To follow up on my previous post, I can report that I did order some nematodes a few weeks ago. Application is very easy – the contents of the packet are mixed with a specific volume of water and then you simply water the lot over your garden. I had 6 raised beds to treat and then used the remainder on specific areas of the wider garden where slugs are causing a problem. I planted out 4 echinacea plants that I raised from seed last year, and within 3 days, they were looking very nibbled and sorry for themselves. I also have an open area of a sunny bed where my dahlias will go, so that was a target area to treat also.
So far, things are looking pretty good. I planted out meteor pea seedlings a week ago and there are very few signs of any slug damage on those. The plants have really started to grow well in the recent warm weather and a couple of them are now showing flowers.
And in the greenhouse, where space is a little tight right, I've been pricking out my tomato plants. Hopefully I will have room to move these onto larger pots next month.I am finding small slugs and snails in the greenhouse still – maybe hitchhiking in on the bottom of a pot? It's not all bad news though as the chickens are making short work of these as a breakfast treat!
