It’s time to get sowing, but don’t be fooled by April’s unpredictable weather
Easter Sunday. The biggest gardening weekend of the year, when the UK wakes and thinks again about growing and mowing. It’s time to open the seed drawer or shed and scream at spiders (though maybe that’s just my kid). April is when we start to think about restocking window boxes and outdoor plants, though I would caution to still wait a while. The watchword is to watch the weather.
There is, however, early summer stuff to sow, though it is safest to stick to your windowsill, at least for the first few days. It is a tricky month, April, safer to grow outside in the south than the north. You are looking for soil temperatures to have reached at least 7C (10C is better). The easiest way to tell is to see how the weed seedlings are doing.
