Summer is here! The work through Winter and Spring in the garden is now bearing fruit!

While there is sure to be lots of opportunity to sit out and enjoy the garden in Summer, there is still a little work to be done with fingers crossed the sun to make it all the more enjoyable! Our June Gardening Tips are a great checklist to keep you on track.

Early June

Mulches help to conserve water but the soil must be moist before they are applied.

When watering concentrate on climbers on walls, container and basket plants, newly planted items, dahlias, sweet peas, leafy vegetables, crops, celery and fruit bushes.

Dig up bare centred alpine plants, divide them re-planting the young pieces from around the edge.

June is one of the worst months for pest and disease attacks, so check plants regularly.

Mid June

Make sure plants in tubs and baskets are fed regularly, as well as watered.

Many climbing plants can be increased by layering at this time of year.

Mow the lawn to leave the grass 2.5cm (1in) tall. Makes grass more drought resistant.

Treat established lawns with a lawn weed killer but not if there is a drought.

Dead head rhododendrons after flowering to encourage new growth.

If you need more fish in your pond this is an ideal time to introduce them.

When picking strawberries always remove any rotting fruit, otherwise problems increase.

Watch out for cabbage white butterflies around your brassica plants.

Sow radicchio now for winter salads. Choose a good coloured variety like pallo rossa.

Sow salad crops regularly, in small amounts, sowing the second row as the first emerges.

Tomatoes can be planted outdoors. Select a sheltered site and support the plants.

Take cuttings from dianthus (pinks). They root easily now in a shady spot.

Lettuce will not germinate in hot weather. Sowing in moist drills in late evening helps.

Shade the greenhouse, ventilate it well and spray water over the floor to raise humidity

Take softwood cuttings from shrubs. Remove 7.5 cm (3in) of shoot tips. Root in pots of gritty compost, placed in polythene bags, in a shady spot.


Late June

Lift and divide flag iris after flowering. Re-plant young growths, keeping rhizomes above soil level.

Prune back side shoots on cytissus (broom) after flowering to keep plants neat.

Deadhead roses regularly to prolong flowering. Remove any “suckers” as soon as they appear.

Watch out for algae and blanketweed in pools. The introduction of a product based on barley straw can provide an organic control measure.

Feed tomato plants regularly from when first fruits begin to form, using tomato food.

Take out one third of the older branches on deciduous shrubs, like Philadelphus, Weigela and Deutzia after flowering.

Put cymbidium orchids outside in a sheltered, shady spot until late autumn. Keep them well watered and fed over this period.

If pollen beetles infest your cut sweet peas, put them in water in a shed for a while. The Beetles will fly into the window, attracted by the light.
