In Gardeners World 2018 episode 27: Monty tackles three seasons of gardening this week when he makes additions to his spring garden, gives advice on how to dry and preserve herbs for winter and plants up a container to give interest from now until spring.

Carol celebrates one of the plant successes of an extraordinary summer – the canna – while Frances Tophill tackles a viewer’s garden and suggests plants which will perform throughout the winter.

How to grow lettuce

Choose the right varieties and you can have lettuce almost all year round. There are so many types of lettuce to choose from – all with different colours, flavours and textures. There are two main types of lettuce: hearting lettuces have a dense centre, while loose-leaf lettuces have open leaves and no heart. You can also grow a variety of salad leaves that can be picked while young and tender.

Dividing perennials

Dividing perennials regularly will ensure healthy, vigorous plants that will continue to perform year after year. It also offers the opportunity to multiply your plants. Most perennials benefit from division every two to three years to maintain health and vigour. For the purposes of propagation, the task can be done more regularly.

10 great plants for winter

There’s something especially valuable about shrubs that flower in winter’s short and often dreary days. Seeing these delightful and resilient flowers taking frost, rain and snow in their stride lifts our spirits. Many are fragrant and can be cut for indoor winter posies.

Winter containers

Containers planted up with a selection of foliage and flowers can brighten up a patio or balcony, giving colour and interest over the cold season.

Growing herbs

Herbs are versatile garden plants. Pretty enough to grow in an ornamental border, many will also thrive in containers. You can also grow tender herbs, such as basil, indoors or in a greenhouse.

Pruning climbing roses

Rose pruning ensures that plants grow vigorously and flower well each year. If left, climbing roses can become a tangled mess of branches with very few flowers. Although often considered complicated, rose pruning is not difficult if you follow this guide.

Honey fungus

Honey fungus is the common name given to several different species of fungi (Armillaria) that attack and kill the roots of many woody and perennial plants. The most characteristic symptom of honey fungus is white fungal growth between the bark and wood usually at ground level. Clumps of honey coloured toadstools sometimes appear briefly on infected stumps in autumn.
