June gardening Tips

There are jobs that must be done in hope of kind weather continuing… Here are some suggestions: Ornamental garden

Gently remove spent flowers from Camellia and rhododendrons to make room for the leaf buds emerging behind. You can also trim back overgrown shoots to make the shrubs more compact, next year’s flower buds will form on the new growth of side shoots that this stimulates.
Divide bearded irises after flowering; plant with the rhizomes facing south.
Sow biennials like sweet William, viola and wallflowers
Divide spring-flowering bulbs.
Remove spent flower heads of Euphorbia by cutting flowered stems to ground level. Wear gloves for this, the sap causes skin irritation.

Lawns

Mow regularly but, if it is hot and dry, raise the cutting height.
Apply a high-nitrogen lawn feed (again, not when dry)
Add clippings to the compost heap in small amounts; mix them with dry material to stop it all going slimy.

Kitchen garden

Pinch out side-shoots of cordon tomatoes
Plant out pumpkins, squashes, courgettes and beans. You could direct sow both these and sweetcorn.
Because sweetcorn is wind pollinated, do not plant them in a row but in a block, so the pollen gets to the stigmas of neighbouring plants.
Harvest early potatoes when they begin flowering
Sow autumn carrots.
Net strawberries and brassicas against birds.
Sorry! But stop cutting asparagus and feed it, so the crowns are ready for next year
