If you put them outside and the weather becomes cold, scorching hot or frosty, bring your plants back in again even if it’s before the allotted time as it may be too much for them to cope with otherwise.

It doesn’t have to be this prescriptive – judge how long to leave your plants outside depending on how well they’re thriving, and look at the weather forecast first – if it predicts frost or scorching sun, keep your plants indoors.

Generally speaking, plants don’t like being shocked (though there are some that respond best to harsh treatment, which I’ll write about another day.) As such, you have to ease them into outdoor living gently, over the course of a week or two, so that they get used to sun, wind, rain and all the other things they’ll have to deal with outdoors. (Should you be interested, the above picture shows peas, strawberries, garlic, tomatoes, pumpkin, mint and cucumber, all of which will be moving outside at various stages over the next fortnight or so.) Basically, this means getting plants used to being outside after growing up n a windowsill or indoors. I decided to start hardening my seedlings off today because there’s still a reasonable amount of cloud cover (baby seedlings freak out in direct sunlight if they’re used to being indoors). One of the joys of sunny days is that they call you out into the garden even when you’ve got proper grown-up things to do (which is why gardening and freelance writing work so well together, because you can garden by day and write stuff to pay the bills by night).
