Every year I fill the windowsills with pots of seedlings, which then need to be planted out in the garden when the weather is suitable. And at this point, it gets tricky!
The best advice is to ‘harden plants off’ gradually over a few days, so that they can adjust to the change of conditions, from potentially hot, dry windowsills to cold, frosty, windy, rainy outdoors. The light levels are also vastly different outside, especially in the ultraviolet spectrum. Unfortunately time and space will not allow me to do any of this. Instead, each year I try to first time the planting of my seeds so that the resulting plants will be just the right size to plant out successfully when the weather is also likely to be right, second I try to look for ‘weather windows’ when a few days are promised that are mild, overcast, and calm, and finally I give them what protection I can muster for the first few days – but this relies on their size being suitable!
Here is my ‘bottle garden’, the bottles now over ten years old but I have come to consider them vital for the successful establishment of sweetcorn. The grass mulch also helps to keep the moisture in. Experience tells me it takes four weeks from sowing seed to planting out – and around here ‘May is out’ (i.e. the Hawthorn is in flower) so I’m hoping they will do okay now!
My courgettes I was much more concerned about, as they are hard to protect. I always loose some plants to weather or slugs, so usually grow some extra and plant close, 18” intervals instead of the recommended 2′. This year, however, I asked for help on when to plant them. I was very surprised that the message came at around 8pm one evening, that it was the time to plant them out. However the forecast was for a mild night, and calm for the next few days, and the soil was nicely moist, so I thought I would give it a try. I also put copper rings around them to give a small bit of protection at ground level and from slugs – these were made from an ex-hot water tank. And the result? A few days on all five are growing strongly and looking really healthy, so much so that I would not know they had been moved had I not just planted them myself. If only the sweetcorn was doing as well!
I am reminded again how, when we accept that we do not and cannot know everything and so ask for help, and when we stay open to the answers in whatever form they come, they are sometimes unexpected. Nature knows best!
