Sow another batch of courgettes
Gardeners call this successional sowing.
Stagger two or three sowings to spread the harvest and avoid a huge glut.
Usually March to May. Moderate source: Sarah Raven.
Mulch the courgette
Spread more compost or manure around the plant to hold in moisture.
Usually May. Moderate source: Gardeners’ World.
Feed the courgette
Once the fruit is swelling, give a high-potash liquid feed every fortnight.
