1. Sow biennials such as wall flowers and foxgloves to flower next year.

2. Prune ornamental cherry trees after flowers have faded. Keep pruning cuts to a minimum as cuts do not heal well and can allow in diseases in – canker for example.

3. Manage ventilation to keep greenhouse cool. Apply shading, damp down greenhouse floors to increase humidity and discourage red spider mite.

4. Summer prune gooseberries, red and white currants at the end of the month.

5. Plant brussel sprouts, sprouting broccoli, cabbage (summer and winter), cauliflowers, celeriac, courgettes, marrows and leeks.

6. Remove carefully faded flowers and developing seed pods from rhododendrons. Remove any unopened flower buds as they may harbour bud blast.

7. Cut runners off strawberry plants unless they are wanted for propagating new plants.

8. Prune spring and early summer flowering shrubs such as philadelphus and weigela.

9. Feed glasshouse tomatoes, peppers, and aubergines weekly with a high potash tomato feed.

10. Last cuttings of asparagus for 2108 is on June 21st, the longest day. Give the beds a top dressing of general fertiliser, mulch with manure or compost to build up crowns for 2019.

General. Hopefully from now on watering the plot will become more of a regular chore, and conserving water is a priority. Avoid spraying water over the foliage of vegetables because very little will reach the important root zone in the soil. Most of the water will evaporate and in sunny conditions the foliage could be scorched. Whether using a watering can or hose pipe place the water under the foliage and over the root. Top dress to retain moisture.
