September Gardening tips
Autumn has arrived! Days are drawing in and it is getting cooler. The garden is still looking good, so we should make the most of it while we can. There are a few jobs that can be done this month -
Divide herbaceuous perennials once they have finished flowering. This will ensure the plant is kept strong and will give you more plants for next year! Lift the roots gently with a fork. Small, fibrous roots (such as on a hosta) can be 'teased' apart. Other plants may need a more solid approach - with a spade to split woody or solid crowns (such as on a helleborus). Always replant as soon as possible and keep watered.
Plant spring bulbs - there is an extensive range of bulbs instore ready for planting in the garden, or in tubs. Remember, as a general rule, plant bulbs to a depth that is equal to twice the height of the bulb.
Continue to harvest fruit and vegetables. Potatoes should be lifted and stored in a cool, dry room. Cut leaves off tomatoes that are shading the fruit to help them ripen.
Clean out the greenhouse or cold frame ready for overwintering plants.
Enjoy the last of the warmth in the garden!
