Berberis ‘Starburst‘
Autumn is a long season of interest in the garden. The autumn colour contributed by deciduous trees and shrubs starts in late August and goes on into December – perhaps one of the longest seasons in the gardening year. Look out for colourful autumn performers that fit easily into any garden. Shrubs for autumn leaf colour include Berberis thunbergii varieties, Euonymus alatus, Ceratostigma willmottianum, Hamamelis x intermedia varieties and Itea virginica ‘Henry‘s Garnet‘.
It is always surprising how many shrubs and perennials flower in autumn. Penstemons continue to produce colourful spikes throughout autumn into early winter. Sedum ‘Herbstfreude‘ turns from pink, to burgundy to mahogany and never loses its charm. Verbena bonariensis continues to attract late butterflies. Hibiscus and hydrangeas conjure up an extravagant autumn display.
This is also a great time to get your lawn in shape. Scarify the lawn now - this is when grass plants produce side growths that help to thicken the lawn. Applying an autumn lawn fertiliser strengthens the grass and gets moss under control before damp winter weather encourages its spread.

Leucothoe ‘Lovita‘
Availability on the plant area is never better than it is now. Skimmias are bristling with flowerbuds nestling amongst their dark glossy leaves. These make wonderful additions to shady borders, or as enduring subjects for winter pots. Leucothoe ‘Lovita‘ is an acid lover but is equally at home in a pot of ericaceous compost. This lovely dwarf shrub turns rich red in winter and will light up the patio or doorstep with its colourful leaves. Heucheras too are at their best now and will stay looking great in the border or in pots throughout winter, certainly delivering a more reliable display of colour than many bedding plants.
Cornus grown for their winter stems often have good autumn colour before the leaves fall and stem colour intensifies in winter. Plant now to make the most of them through two seasons, rather than waiting until everyone wants them in midwinter.
The same is true of those shrubs that brave the elements to produce fragrant winter flowers. When they are doing their stuff they disappear from the garden centre benches all too quickly. Buy them now and you have their fragrance to look forward to this winter, as well as for years to come. Daphne bholua ‘Jacqueline Postill‘ and Sarcococca confuse.

Rhododendron ‘Nancy Evans‘
Flower bulbs are an easy decision when it comes to choosing plants for the garden. Their reliable performance comes with the minimum of investment. Dwarf bulbs such as crocus, iris and snowdrop should be planted as soon as you buy them. You have until December to plant tulips and large flowering narcissi, but do not put off buying until then as the choice is greatest now.
The soil is moist and warm and, although above ground the growth of trees and shrubs starts to slow, below ground roots are active. This is the best time therefore to plant those important trees and shrubs that form the backbone of any garden. Rhododendrons and azaleas look at their best now and the selection of varieties is greatest. Some have wonderful foliage that will add to the garden in winter, but still with those wonderful flowers to look forward to in spring. For those gardening on chalk these are still worth considering for pots and raised beds.
If you are considering a hedge, or just need a few screening shrubs then now is a great time to plant. Evergreens will continue to grow and develop throughout winter, so you are buying time if you plant in autumn rather than spring.
Some summer flowering bulbs such as lilies and alliums are planted in autumn. Both subjects add different shapes and colours to the planting picture and fit in anywhere. Planting bulbs now is much cheaper than buying them as pot grown plants later in the year.
This is also the best time to plant roses. Be honest with yourself about the performance of your roses this summer. If once again your roses have failed to deliver much more than a splendid display of blackspot it is time to get rid of them and plant some decent ones. The newer varieties of English Rose raised by David Austin are more resistant to disease and will flower throughout summer if planted now. If you are planting where roses were growing previously you do not need to change the soil, just use Rootgrow when planting.
