• Try to make a small water haven for wildlife, using any large container. This can attract beneficial insects, frogs and toads, which clear up pests like aphids and slugs for you.
• Keep your eyes open for pests and diseases in the greenhouse and the garden, and take appropriate action immediately to stop the problem getting out of hand.
• Weed regularly.
• If the weather is dry be prepared to water vulnerable plants.

Lawns

• Trim your lawn at least once a week to keep it neat and dense.
  
• You can aerate your lawn in late September or October. A garden fork works well for this. Rake sand into the holes to improve drainage.

Containers

• It is essential to keep all container plants well watered
  
• Tidy summer containers.
• Remove fading flowers regularly.

Annuals and biennials

• Start sowing hardy annuals now.
  

Perennials

• Plant Rudbeckia 'Goldsturm', Sedum 'Autumn Joy', Autumn Asters and Japanese Anemones.
• If you lifted your daffodils, tulips and hyacinths this spring, check them for rot, dust them with sulphur powder and set them in a cool, dark, dry room to prevent premature sprouting. They should be back in the soil by late September

Roses

• Spray bush and climbing roses with fungicide and insecticide mix.
• Dead head regularly to maintain flowering.

• Plant groundcover, flat or gently sloped areas are best.

Vegetables

• Start lifting root vegetables, and store some ready for when the frost prevents digging.
• Protect the remaining summer vegetables with cloches.
• Earth up the last celery, bulb fennel, leeks and celeriac.
• Plant your spring cabbage seedlings.
• Lift the remainder of your maincrop onions.
• Lift all remaining potatoes and, at this late stage, burn the foliage to kill blight spores.
• Cut the runner bean plants but leave roots in to nourish the soil.
• Spray brassicas with Bio-BT (bacillus thuringiensis) to kill caterpillars, or remove by hand.

Herbs

• Chives should be lifted and divided every three years. If you want to grow them in the same place, lift them, heel them into a spare piece land. Dig over the plot incorporating well-rotted manure and replant.
• Comfrey, the above is also true for this plant as both are perennial.
• Sorrel, if you can buy or obtain an established root this is the best time to plant, although it can be raised from seed this method is far quicker.
• Fennel the herb, not the bulb can be planted now.

• Take nets of fruit after harvesting to allow birds to get to over wintering pests.
  

• Remove greenhouse shading at the end of this month.
