July…in your garden
Here we are again, the months are flying by the longest day has been and gone. We’ve been very busy here at Thorngrove planting up basket plants and hanging baskets for our customers. So here I am again doing tips for July to help keep your garden and plants looking good!
- Keep dead heading perennial and Annual flowers to help prolong there flowering period.
- Cut back delphiniums and geraniums after first flush of flowers to encourage a second flowering period. Feed after cutting back.
- Plants with a carpet-like growth habit e.g.some alpines can become patchy, with central area dying off. These can be in-filled with gritty compost to encourage new re-growth.
- Take cuttings of patio and container plants ready for next year.
- Repot Snowdrops if growing in containers.
- Water your pots and containers daily and feed regularly.
- Prop up tall perennials such as lupins, delphiniums and gladioli if staking was neglected earlier in the season.
- Mulching borders can help retain moisture and keep down weeds-this will save a lot of work a really thick layer of mulch (5-7cm/2-3inches all over) works best.
- Most perennial weeds are best dealt with in the summer when they are in active growth. Digging out often works, but applying a weed killer can be more practical, particularly for large areas.
Pest and Disease watch
- Inspect lilies for scarlet lily beetle. The larvae can strip plants in days, if you see them remove and dispose of.
- Vine weevil can also be a problem at this time of the year.
- Watch out for Aphids (greenfly and blackfly) on stems and leaves of young shoots.
- In dry weather powdery mildew can play havoc with plants such as Clematis Roses and Lonicera, spray with a fungicide at the first signs this will help keep it under control and stop it spreading.
- Look out for and treat black spot on Roses and scab on Pyracanthus.
Trees and Shrubs
- Prune June flowering shrubs such as Philadelphus and Weigela, after flowering, prune deciduous Magnolias if necessary.
- Fast-growing hedges such as Leylandii should be clipped as necessary throughout the growing season.
- Tie in Rose climbers and ramblers as they grow.
- Look out for tall flowering stalks of established Bamboos and remove them promptly as flowering can weaken the plants as well as being unsightly.
- Ensure newly planted trees and Shrubs are not allowed to dry out as they often need more water than people imagine.
- Remove any rose or tree suckers.
- Take softwood cuttings from shrubs such as Pyracanthas, Cotinus, Hydrangeas and Spireas
- Keep your ponds and water features topped up a spray attachment on the hose will help aerate the water, and help the fish
- Any pumps on water features should be left on during Sultry nights. As oxygen levels are lower in these conditions.
- Remove dead foliage and blooms from waterlilies and other Aquatic plants.
- Cut back any marginal plants that are getting out of hand.
- Continue to skim of blanket and floating weeds.
- Keep mowing regularly, except in drought, in hot weather set your mower at a slightly higher level than normal for early Summer. This can prevent the lawn dying in hot weather.
- This is the last chance to apply a liquid Summer lawn fertiliser especially if a Spring feed was not given
- If you have weeds a soluble feed and weed products maybe useful.
- If you have laid new turves or sown grass seed these may need extra watering to get them through there first Summer.
