Gardeners' World, 2011 Episode 11 of 28

Duration: 30 minutes

By the first week of June, plants are growing with such speed that some have a tendency to flop. Staking is the answer. As well as sharing his tips, Monty Don shows how to make stakes that can be used for many years to come. Now the nights are guaranteed to be frost free, Monty plants out the tender annuals he's raised from seed.

Carol Klein visits a Wiltshire gardener and bee keeper who wants to make the most of a shady area by planting nectar rich plants. Carol helps by choosing plants with flowers which will not only attract her honey bees but will give much needed colour.

Rachel De Thame discovers the benefits of The Chelsea Chop from the experts at RHS Wisley. Here some flowering perennial plants are cut back to trick them into flowering later.

Back at Longmeadow, Monty turns his attention to his citrus trees and shows how, with a bit of TLC, they will spend the summer in tip top condition.



    You don’t need to turn your garden into a wildlife meadow to attract bees. There are plenty of garden flowers that will provide them with the nectar and pollen that they need. Nectar is rich in sugar and acts an energy source, while pollen contains proteins and oils. Some plants are more attractive to bees than others. Here are some of our favourites. To provide a continuous source of food, it’s a good idea to grow a range of plants that flower at different times of the year.

    Alcea rosea (Hollyhock)
    Aquilegia (Columbine)
    Dahlia (single-flowered)
    Digitalis purpurea (Foxglove)
    Echinops (Globe thistle)
    Erysimum ‘Bowles’s Mauve’ (Perennial wallflower)
    Hardy geranium
    Helleborus (Hellebore)
    Lavandula (Lavender)
    Lonicera (Honeysuckle)
    Monarda (Bee balm)
    Muscari armeniacum (Grape hyacinth)
    Nepeta (Catmint)
    Pulmonaria (Lungwort)
    Sedum spectabile (Ice plant)
    Verbena bonariensis

    Citrus plants are best grown in pots so that they can be brought indoors over the winter. They won’t do well below 7°C but will enjoy a spell outside from June to September. They are quite hungry plants, so it’s worth using a nutrient-rich compost such as John Innes No.2 with a bucket of grit or sharp sand mixed in.

    Citrus plants are slow growers and so don’t need to be potted on very often. If you’ve bought a large plant and want to keep it in the same pot, you can either scrape off the top couple of inches of soil and replace it with fresh compost, or take the plant out of its pot and completely change the compost. Only trim the roots if they have filled the pot. Pinching out the shoot tips will also help to produce a better shaped plant. Keep well fed and watered.

    If you haven’t got round to sowing any French or runner beans yet, there’s still time. And now that the risk of frost has gone, they can be sown straight into the ground. Erect a wigwam of canes for support and lash them together at the top with twine. Sow a couple of seeds at the base of each cane, weeding out the weaker of the two once they’ve germinated.

    Biennials grow one year and flower the next, so you need to be sow them now to guarantee a good display next year. Examples include foxgloves, wallflowers, honesty and sweet william. Sow them in a tray of compost and stand them outside – they don’t need much heat to germinate. When large enough to handle, pot them on or transplant them into a spare part of your garden. Keep well watered until you’re ready to plant them out in their final position in the autumn.

    When the weather turns hot and sunny, don’t waste your time trying to water your whole garden. Focus your attention on newly-planted specimens and plants growing in containers. With fruit and veg, concentrate your efforts on seedlings and young transplants, early potatoes, lettuce and spinach, along with anything that’s flowering or fruiting. Water in the evening or first thing in the morning and aim to water to the roots of your plants rather than wet the foliage. A thorough soaking once a week will do them far more good than a light sprinkling every day.
