November Top Tip
Continue to plant spring-flowering bulbs such as crocuses, dwarf irises and tulips. If your borders are full plant them in large pots instead. These bulbs can be planted out to fill gaps later.
Any perennials past their best can be cut right down, clearing away remains and adding them to the compost heap.
Evergreen shrubs and conifers planted now will get a really good start in life, also complete new hedging projects as soon as possible.
Perennial Michaelmas Daisies asters produce striking display of bold daisy flowers from late summer for an attractive autumn show. Lift and divide clumps every second or third year after removing old flowering stems and replant the new sections, watering them in thoroughly.
Fill gaps in borders with wallflowers for a great blaze of spring colour. Space them so that they will grow into one another and, for extra impact, plant tulips with flowers in a contrasting colour between them.
Plan a continuous supply of crops for harvesting through the autumn months and into winter by planting hardy lettuce varieties such as ‘Winter Density’ in growing bags, pots or border soil.
Chives are a valuable garnish at any time of year for sprucing up a salad, adding flavour to potatoes and colouring winter soups. Lift and divide congested clumps that have lost vigour every few years. Small clumps can also be grown in pots on the windowsill. Keep some chives by the kitchen window for convenience.
Sow broad beans such as ‘Aquadulce Claudia’ and pea ‘Feltham First’ in early November. In colder areas it’s better to wait until spring or to sow them in pots which can be planted out in spring.
Garlic cloves from strains that are selected to suit our climate can be planted outside now. Alternatively, raise them in pots to plant out later. Planting selected onion sets in autumn will give you a crop from late June into early July.
Sweet Peas should be sown in pots now in a cold frame or greenhouse ready for planting out next spring.
