If you have not already done so then cut back the dead foilage from winter plants such as daffodils. Allow spring flowering bulbs to decay naturally as the bulb will draw back nutrients from the leaves

If you are growing Ornamental Poppies then cut back faded flowers and leaves to encourage further growth.

Cover Strawberries with netting to keep birds and other animals away from the fruit.

Grow Aubergines and Peppers in grow bags in a sunny part of the garden.
