What to do in the garden in September

September is the time of year when the garden experiences a revival, and as the weather warms up, there are more gardening days. This is the time to start planting your summer crops, mulching in preparation for summer, planting edible annuals, and doing a general clean-up to get your yard in top shape.

What to Plant

While the transition from winter to spring can bring with it unstable weather, now is the time to prepare your summer veggie patch. Start by planting basil, corn, climbing beans, zucchini and tomatoes. Keep in mind that if you are planting seeds, they will require warm soil to start growing.

For temperate climates, you can sow seeds for broccoli, beetroot, spring onion, carrot, lettuce, potato, silverbeet, tomatoes and peas to name a few. And almost all veggie seedlings can be planted now. For first-time tomato growers, here's some advice on how to plant them.

Consider planting popular natives bottlebrush and correa for a splash of colour. Roses, lavenders and a large array of annuals, such as snapdragons and petunias, are available as seedlings. Another favourite is potted colour (including impatiens) for a quick spring display in the garden, pots or hanging baskets.

To work out what’s best to plant based on your climate, ask your local Bunnings team for advice, as they can help you plan to plant while taking frost, salt winds, soils and humidity into consideration.

What to Pick

A range of camellias, cyclamen, and agapanthus, are in bloom. It’s also the perfect time to harvest asparagus, celery and dill. Raid the veggie patch as Asian greens, lettuce, chicory, English spinach, mustard lime streaks, broad beans, cabbage, leek, parsnip, pineapple, star fruit and a variety of citrus are also in season.

What to do

Divide and conquer
September is the time to divide plants such as rhubarb, horseradish, artichoke, ginger and arrowroot.

Fertilise
Give your perennials a head start with liquid fertiliser every fortnight, as well as general fertilising for garden beds and lawns before you start mulching in October.

Cover up
Keep an eye on the weather forecast in temperate climates as a late frost can wipe out an entire crop. The best way to combat this is using hessian or gardening shade cloth to cover your seedlings so they have the best chance of survival.

Clean up
If you have a chook shed, now is the best time to give the enclosure a thorough clean out. You can also use dynamic lifter on your citrus trees now. To get started this September, check out our extensive garden range.
