Autumn is an ideal time for planting and transplanting; the sun warms the soil and the ground is moist due to shorter days and autumn rains. If there’s a shrub you wish to move, roses you want to transplant or perennials that have been in the wrong place then lift and move them to new homes now. Dig a circle around the base of the plant at least 12” from the stem and dig underneath so as to keep as much soil around the roots as possible. Transplant to the new site (planting at the same depth) and water well.
September is a great month for planting pot-grown fruit such as apples, pears, cherries, plums, gooseberries, currants, and more. It’s also an ideal time to plant ornamental trees, shrubs and conifers.
In sunny gardens with well-drained soil, plant onion sets, shallots and garlic for an early crop next year; however, if your soil is heavy and moist then leave until next spring.
Start your bulb planting this month for spring and summer. The choice is huge: Daffodils, Crocus, Hyacinths, Dutch Iris, Alliums, Anemones, Cyclamen, Muscari, Scilla and Aconites to mention but a few.
Leave Tulip planting until early November. Plant bulbs in natural drifts in the lawn by scattering the bulbs over the grass and planting them where they land. Alternatively, plant in pots, hanging baskets, troughs or in beds and borders.
Cheap & Cheerful
September is a great time for creating plants for free. Collect ripe seed heads from plants such as Poppies, Delphiniums, Foxgloves, and Lupins when the heads are brown and dry.
Collect the seed by shaking the seed heads into envelopes, then sow and grow next spring. Check gravel paths and borders for young seedlings such as Alchemilla, Lavender, Persicaria, and Oenothera. Lift and pot these to create new plants for free. Take hardwood cuttings from shrubs such as Cornus, Willow, Lilac, Philadelphus and Deutzia. Cut lengths of stem from brown wood on your shrubs just above a leaf joint and then trim down from about 5” to just above the leaf joint. Cut the top at an angle and the bottom straight. Push into the edge of a pot containing gritty well drained compost. Leave somewhere bright and sheltered, water when dry and by this time next year you should have new young plants.
Once the leaves begin to fall, clear them from your lawn and treat your grass to an autumn lawn feed- this will create healthy root growth and will help to control the moss.
Bring in house plants that have been outside for the summer and reduce watering and feeding as the days shorten.
Remember though, its only September, so keep dead-heading, watering and continuing to love you garden.
