With autumn starting to make itself felt, September sees the beginning of lots of change in your garden. Stay on top of things with my key gardening jobs for September…
Sow seeds now for colour next year
The cheapest way to pack your garden with colour next year is to grow hardy annuals like pot marigolds, larkspur and love-in-a-mist. If you sow the seeds now in a sunny spot outdoors, they’ll start flowering extra early next summer.
Dig up potatoes
Lift the last of your potatoes before the slugs get to them. Dig them up on a sunny morning, leave them on the soil to dry out completely during the day then store in paper bags in a cool shed or garage.
Trim your hedges
Privet and lonicera hedges need a final trim of the year to get them tidy for winter. It’s also the last opportunity to cut evergreen hedges like leylands, yew and laurel.
Bring in houseplants
If you put any houseplants outside for the summer, it’s time to bring them back inside. Trim off any damaged or yellowing leaves and check for pests, especially slugs which may be lurking in the drainage holes. If you spot any pests, spray with Plant Invigorator before you bring your plants indoors.
Keep your summer pots looking good
To get the most from your summer pots for as long as possible, keep them well watered and feed them twice a week with a high potash feed like Flower Power. Also, take off any finished flowers to stop the plants from going to seed.
Grow your own garlic
Home-grown garlic is much milder, tastier and fresher than the supermarket’s. For best results, get a pack of special cloves from the garden centre and plant them in well-drained soil. Harvest them from mid-summer.
