Autumn Is Here...
A heatwave at the start of September was the last-hurrah of Summer and then we transitioned into cooler and wetter weather for the rest of September. October is looking to start fair, but cold weather and frosts will not be far away. There is still a lot of colour in the garden and the trees will soon be putting on their autumn colour show, so enjoy this transitional time. Perhaps with a cup of tea and the new Worplesdon Garden Club October Newsletter.

Jobs to Do in the Garden this Month
Into Autumn...
Continue to take cuttings of most half-hardy or tender perennials such as fuchsias, salvias and pelargoniums, as well as semi-ripe cuttings of woody shrubs such as rosemary and lavender
As early flowering annuals begin to fade, choose a warm, dry day to collect seed and store in paper envelopes or pouches made from folded kitchen paper
Fill in any gaps in the garden with spring bedding such as pansies, forget-me-nots and bellis
September and October are perfect times to divide congested clumps of many perennials after they have finished flowering. Dig up, divide, replant, and water-in well. The warmth of the soil will mean they will re-establish quickly. If the clump is very large it is usually best to only take new plants from the edge and discard the older, woody centre
In the vegetable garden and greenhouse, continue to harvest as soon as fruits are ripe
If you are growing pumpkins or squash, trim away any leaves that are covering the fruit so that the sun can harden the skins before harvesting.
Winter onions and garlic (hardneck) can be planted now, but not in the same location as the previous crop - ideally, rotate vegetable beds on a three- or four-year cycle: Onions and Roots > Potatoes > Brassicas > Legumes
Lawns may need some autumn maintenance. Scarify to remove thatch, aerate, and apply a lawn feed suitable for autumn application (low nitrogen, high potassium) as well as addressing weeds with selective herbicides if required. New areas of grass should be sown now, or thin areas of lawn raked and overseeded.
Many hardy annuals such as cornflower, Ammi, and sweet peas can also be sown now for an early display next summer, or perhaps sow a patch of wildflowers, but choose the right seed mix for your soil type and aspect (light, moisture, etc.)
Dahlia and Begonia tubers should be lifted once the top foliage has turned black with the first frosts of October (if we get any this year!) - Lift carefully to avoid damaging the tubers, trim off the dead foliage, label, then store in dry sand or compost in a cool, frost-free place. Alternatively, apply a thick layer of mulch over the plants in situ to protect the tubers from frost.
Catalogues and websites for seeds, bulbs, and bare-rooted shrubs are available now so start planning how to make your garden even more spectacular but remember to enjoy what you have now
