Don’t forget
Sow hardy annuals such as love-in-a-mist and pot marigolds into gaps in your borders
Plant polyanthus in pots near entrances and paths to brighten them up
Cut back long, old stems on hydrangeas to give a better-shaped shrub
Check roses for aphids and rub them off before they do damage
Plant water-lilies in ponds for summer colour
Tie in any climbing roses that have come loose
