September garden plant maintenance

September garden plant maintenance in Wokingham and Maidenhead

The hay is in already…

September marks the end of summer and the beginning of autumn – and what an amazing summer it has been, not that the garden thought so of course, what with the heat and the hosepipe ban! And oh, our poor lawns! They must be running on empty and longing for several good sessions in the rain. The RHS advises waiting until autumn before making repairs to lawns and to delay lawn weed killer treatment on brown lawns until the following spring.

Come September/October, the grass will start to regenerate. Any dead leaves and things that have been allowed to accumulate on the grass will contribute to thatching, so aerating and scarifying are vital. This will help your lawn produce a better and deeper root profile. Autumn lawn feeds are low in nitrogen but have higher values of potash and phosphate which promote root growth. Scarifying your lawn along with aeration will get rid of any thatch that has built up in your lawn and get more oxygen down to the roots and reduce compaction. All this effort means that your lawn will be in better shape to face the rigours that the summer of 2019 may throw at it! If you do not feel confident in doing this yourself, do get in touch with us at Gardeneer as we are always pleased to help.

Now is the time to prepare for next year. Autumn is usually the best time for planting because the soil is still warm and the rain gets new plants established before winter sets in. September is the optimum month to visit your local garden centre or nursery and purchase spring flowering bulbs such as Daffodils, Crocus, Tulips, Snowdrops etc. Think about colour schemes, which shrubs may be in flower at the same time and what height they will be. Once purchased, get them into your borders as soon as possible.

Talking of bulbs, here are some autumn flowering bulbs to look out for: Nerine bowdenii with bright pale pink trumpets, great for containers or sunny hot borders. Schizostylis coccinea grows showy little bulbs which really stand out with their bright red star-like flowers. And Colchicums, commonly known as Autumn Crocus or naked ladies as they flower with no leaves. They are great for borders or naturalising in lawns

Why not book a Gardeneer tidy up session to get the straggly borders weeded, tidied and pruned so that you can enjoy your garden looking just the way you like it.

Jobs for September

  • Review your shrubs/herbaceous plants’ performance this year and make notes; this helps to make decisions next year when planning your garden!

  • Ripen any remaining tomatoes indoors from the end of September.

  • Sow winter vegetable crops such as lettuce, turnips, spinach and winter onion sets.

  • Reduce roses to prevent wind rock (loosening of the roots caused by the wind blowing through top heavy roses).

  • As already mentioned, autumn feed lawns – scarify and aerate if necessary.

  • Lift Dahlia and Canna tubers before the first frosts.

  • Give evergreen hedges their final trim.

  • Also, this year being so dry, keep your Rhododendrons and Camellias well watered to help them with good flower bud formation
