September definitely has an autumnal feel about it. We still have sunny days but the grass in the morning is heavy with dew, and there’s a noticeable slow down in the garden. However there's still plenty to be done so we've put together our top gardening tasks for this month.
In the flower garden:
* It is important to continue to feed and dead-head your hanging baskets and container plants - they will often keep going until the first frosts.
* Keeping annuals and perennials deadheaded will help to extend their performance.
* Filling gaps in borders with autumn flowering plants such as sedum and chrysanthemum will extend the colour to the end of the season.
* With wetter weather arriving this month, it's the ideal time to order trees and shrubs. They will grow vigorously next spring if planted this autumn.
* It is great time to prune any late-summer flowering shrubs as well as climbing roses and rambling roses once they've finished flowering (unless they are repeat-flowering, in which case we are leaving them).
* Time to prepare for autumn cleanup. Start removing any plants that have finished and clear away weeds to leave beds tidy for the winter.
* Think about which bulbs you would like for next spring - now is the time to order ready for autumn planting.
Looking after your lawn:
* Autumn weather is favourable for good lawn establishment. We are happy to Create new lawns from turf or seed.
* Time to raise the height of our mower blades as grass growth slows down.
It is also good time to carry out essential lawn maintenance to avoid water logging and compaction. We are aerating our clients lawns with a garden fork, raking thatch from the surface and repairing dead patches. After carrying out maintenance work we will apply a special lawn top-dressing.
* Where necessary we recommend feeding lawn with an autumn fertiliser now, which is rich in potassium and low in nitrogen.
Other jobs around the garden:
* Dispose any diseased plant material by burning it or putting it in with your household waste. Don’t compost it as the spores may remain in the compost and reinfect your plants.
* Raise pots off the ground for the winter by using bricks or 'pot feet', to prevent water logging.
* Clear pond weeds and net your pond in anticipation of autumn leaf fall.
