You may need to strengthen your lawn for winter by applying an autumn lawn feed which is high in potassium to strengthen the roots. Avoid using old summer feeds as these are high in nitrogen, which at the wrong time of the year could encourage lawn diseases.
What some people call a weed, others call a wildflower: if you like it then why not look for the seed heads to ripen then pluck off the heads and shake them over a chosen area where you would like to have wild flowers next year. Poppies for example take easily from casual sowing like this; same applies to your more traditional perennials.
Buy or order spring-flowering bulbs. Daffodils are traditionally planted September/early October for best results. Tulips are best until November. There are many other bulbs to choose from, so visit a garden centre to see what’s available.
It’s okay to plant new perennials as the ground is still warm but moist, which means they will have time to establish before winter. You can always buy spring-flowering bedding plants such as Bellis, Primula, wallflowers and violas.
Continue cutting back any perennials that are fading and dying down. Deadheading plants such as Dahlia, Delphinium and penstemon will prolong the display and give colour well into the month.
Your hanging baskets will also benefit from a little deadheading and feeding to keep them going until mid-autumn.
Divide any overgrown clumps of alpines and herbaceous perennials to invigorate them and improve flowering next year.
You can still apply weed killers to kill most perennial weeds.
Greenhouse and Houseplants
If you use your greenhouse then remember to clean it before you fill it with plants you want to protect from frost over the winter, hose it down and then use a safe cleaning product such as Citrox to kill off any pests.
