This week I had the pleasure to meet Mark Ridsdill Smith who runs “Vertical Veg” a website that is about the art of growing vegetables in small spaces.
He came to film the various ways I grow tomatoes and we had a an enjoyable but challenging time filming in high winds!
To visit his website and find out more about “Vertical Veg”, here’s a link: http://www.verticalveg.org.uk/
Instead of writing a long newsletter, I’ve made a short video about pruning leggy plants and the benefit of using magnesium (epsom salts) as a foliar spray.
Increasing the amount of light absorbed by plants is important – especially if light levels are poor.
Two or three seasons ago, we had such low light levels throughout the spring and early summer that flowering was delayed and even garden centres were struggling with all sorts of low light issues.
One of the best ways to increase light is to use reflective white surfaces.
I like to cover almost every surface in white plastic including my polytunnel floor!
I have never understood why they make black pots or perhaps I should say … pots black (perhaps to hide the dirt). In direct sunlight roots become very hot and plants become stressed at high temperatures. Actually, white pots are now available from some manufacturers who realise an opportunity!
A few sheets of reflective plastic here and there can make a real improvement but let’s hope we also get a good light and sunny summer!
As we approach the time (end of May) when we can leave plants out overnight and the danger of frost will have past, it’s still good to cover tomato plants with garden fleece to help prevent wide temperature changes between day and night.
Wide temperature swings tend to stress plants and make them less vigorous.
