Heatwave gardening

So, we're set for a heatwave? Good news for some, bad for those who don't like hot sticky weather. Here are our tips for avoiding the worst problems.
If humanly possible water last thing at night. Pour water directly on the roots rather than sprinkling.
Avoid getting water on leaves especially on hot mornings - it can cause scorching.

If using liquid feeds use them more dilute - half strength - to avoid damaging roots with too-strong solution in dry conditions.
Don't spray pesticides in the morning in bright sunlight - wait till evening or when it's cloudy.
Newly planted seedlings can be scorched by bright sunlight if you move them staright out of a shaded greenhouse - "harden them off" to sunlight just as you would to frost.

Take care of yourself too: don't get sun stroke!
