Gardening Tips for September

September Gardening Tips

Here is our round-up of news, top tips and ideas to make the most of your garden!

September is a busy time in the garden. Conditions can quickly change from summer to the onset of winter, so getting on top of jobs now to save time and effort next spring is always beneficial!

Keep reading to discover our top gardening tips, what to plant and what to watch this month!

SEPTEMBER GARDEN CHECKLIST

• Tidy up strawberry plants. Cut off the old leaves, leaving just the youngest in the middle. Weed the plant, looking specifically for fruit debris, which can harbour fungal disease spores and damage the next year’s crop.

• Divide and replant herbaceous perennials. Division of plants is most successful when the plants have stopped flowering and are not in active growth.

• Stop feeding container perennials. To discourage weak growth, cease from feeding any perennials you are growing in containers.

• Save bean seeds for sowing. Leave French bean pods on the plants until they go brown and dry, and then cut them off. Open the pods to inspect the beans – store the good beans in an envelope until next spring.

• Cover late vegetable crops. Use cloches or horticultural fleece to cover late crops of vegetable, such as carrots and salads.

• Pot up herbs. Put herbs like basil, coriander and parsley into pots to bring under cover.

• Plant wildflowers. September is the perfect time to sow and plant wildflowers, which benefit the larval stages of many pollinators.

• Remove dead leaves. Use a rake to keep borders and lawns free of dead leaves. Collect them to create leaf mould.

THINGS TO SOW, GROW AND HARVEST IN SEPTEMBER

• Plant onions. Utilise ground that has been cleared of summer crops, such as French beans, lettuce and carrots, to plant autumn onions. If the previous crop was deep-rooted, take extra care in raking the soil to level it out.

• Plant spring cabbage. Before the soil cools down too much, plant out spring cabbage.

• Prepare cauliflower. This month, sow hardy varieties of cauliflower in modules to overwinter in a coldframe or unheated greenhouse, and then plant out in spring.

• Harvest late raspberries. The colder it gets, the more likely raspberries are to rot on the plant. Pick the berries as soon as they ripen.

• Harvest sage. A delicious addition to many autumn and winter dishes, keep cutting fresh leaves for use in cooking. If you have more than you can use, hang small bunches upside down to dry for a few weeks. They can then be stripped and stored in an airtight jar.

• Harvest first parsnips. Pick every other parsnip in a row, easing out the roots gently using a garden fork. This allows the left over roots to get larger before harvesting later in the winter.

• Pick dahlias at their peak. Dahlias are a beautiful plant to have in the garden, but they also make for fantastic indoor displays. Pick once fully flowered, as they will not continue to open once cut. Pick weekly to encourage the outdoor plant to produce more and more flowers.

IT’S NEVER TOO EARLY TO STOCK UP AND SEASON YOUR FIREWOOD!

New regulations introduced by the Government earlier this year mean that partially seasoned logs must be seasoned further prior to burning to ensure that moisture content levels are below 20%.

We’ve been busy making sure each of our centres is stocked up with firewood and log stores ready for the colder months ahead!

Perfect for seasoning logs and keeping them dry throughout the colder months, stock models and bespoke models of our log stores are available from Midgley, Brigg and Wentworth.

GROWING FLOWERS FOR THE FUTURE

Ensure your spring garden brings with it a flood of colour by planting these bulbs now!

• Galanthus elwesii ‘Beluga’. This rare variety of Snowdrop will provide a crisp white backdrop, perfect for highlighting the vibrant colours of accompanying plants.

• Iris ‘J.S. Dijt’. These bulbous perennials produce pendent petals of a rich purple hue with flashes of yellow.

• Primula veris ‘Gold Nugget Red’. Primula veris are often the first to flower in an early spring garden, producing vibrant red flowers with bright yellow centres.

• Cyclamen coum ‘Album’. The white form of Cyclamen coum, the ‘album’ grows a delicate white flower with a violet centre and almost silver foliage.

• Thymus ‘Silver Queen’. This sweet, lemon-scented herb grows in the form of a dwarf evergreen shrub, with dark green, edible foliage.



PUTTING POLLINATORS FIRST

Many garden flowers produce no nectar or pollen whatsoever, making it difficult for pollinators to get the nutrients that they need.

Now is an ideal time to plant many wildflowers, meaning they will be well-established by next spring. Here are some ideas for what to plant depending on the space and conditions available.

To plant in sunny beds or pots

• Cornflower. Bees love blue flowers, so the annual Cornflower is a staple!

• Common teasel. This biennial plant provides seeds that golfinches feed on throughout autumn and winter.

• Sea holly. This spiny-leaved perennial is a pollinator favourite.

To plant in the light shade of trees or shrubs

• Red campion. An important flower for day butterflies, bees and flower flies.

• Tufted vetch. A firm favourite of bumblebees, who are happy to venture into dappled shade.

To plant in longer grass

• Meadow cranesbill. A deep violet blue flower, which is a caterpillar food plant of the Brown Argus butterfly.

• Dropwort. An adaptable plant but best suited to dry grassland.

• Ox-eye daisy. This vibrant plant attracts various pollinating insects, predominantly beetles, hoverflies and caterpillars.

To plant in shorter grass

• Red clover. Produces an abundance of nectar for many long-tongued bumblebees and rare species of bumblebees such as the great yellow bumblebee.

• Dandelion. Rich in both pollen and nectar, each bright yellow head contains around 100 individual flowers.
