Are you going on holiday?
If you’re going on a late holiday either arrange to have your containers and baskets watered, or set up a system that can supply water on a regular basis to your tubs and baskets.
Move any baskets and containers out of full sun to a position where they are shaded at the height of the day.
Stand terracotta pots on gravel trays topped up with water, so the pots can gradually absorb the reservoir of liquid.
Alternatively make a few holes in the lid of a plastic water bottle, cut off the bottom of the bottle, turn upside down into the plant compost and then fill with water (which slowly drips into the soil).
You can apply the same watering principles to your veg patch as well.
