Gardeners' World, 2012 Episode 18 of 31

Duration: 30 minutes

As the garden reaches an abundance of growth in August, it is the pond, hedges and edges of the garden which are the focus of attention. In the pond, the growth of algae is at its height, so Monty recommends some plants which will eventually improve the quality of the water and help to prevent this unwelcome growth. He also gets going on cutting the hedges and mowing areas of the garden where the grass has been left to grow, so that the wildflowers can seed themselves ready for next year's display.

Joe visits a garden on a Welsh mountainside and finds out how the owner has risen to the challenging topography, frequent torrential downpours and often waterlogged site, and made a lush, colourful and verdant garden.

And at Glebe Cottage, Carol answers viewers' queries about the proliferation of slugs and snails in our gardens this year. She recommends some plants we can add to our gardens which molluscs won't be so keen to munch on.

  • POND CARE

    POND CARE

    Monty’s new pond, like many a pond in high summer, is suffering from algal bloom. It can manifest itself as a ‘pea soup’, floating green scum, or threads of silk and blanket weed. As algae grows it draws oxygen from the water, so it is important to remove it. Monty introduces oxygenating plants; as they grow they will draw nutrients out of the water, hopefully out-competing the algae, and most importantly they will add vital oxygen. This will benefit both the plants and creatures living in the water.

  • CUTTING MEADOW GRASS

    CUTTING MEADOW GRASS

    A wildflower rich meadow is a joy many of us would like to possess. Acres of land are not needed to achieve such a delight. By simply leaving an area of lawn un-mown, wildflowers, like clovers, buttercups, and vetches will colonize if left alone. If patience is lacking the process can be speeded up by planting wildflowers as plugs. Knowing when to cut is crucial in maintaining the cycle. Monty leaves his wildflower rich grass until late summer when the flowers have gone to seed. After he takes his first cut he rakes off all the grass and adds it to his compost heap. That way the nutrients within the cut grass are not returned to the ground. Wildflowers thrive in impoverished soils.

  • JOBS FOR THE WEEKEND: COLLECT SEED

    Collecting seed from your garden is a cost effective way of increasing stock of favourite blooms. Paper bags or envelopes are best for storage; they allow the seeds to breathe, keeping it viable for months. If you spot a flower that is unusual, different from the rest, it is worth marking it with a thread or ribbon; it can be identified later when the seed is ready for collection. Remember not all seed comes true.

  • JOBS FOR THE WEEKEND: TURN COMPOST

    Many of us start our compost making with enthusiasm, with a will to get the mix right, to turn it regularly, and do the right thing. We flag and the compost heap becomes a dumping ground, thick sludgy layers of grass clippings interspersed with weeds and hedge clippings. Turning it is the best thing to do; it will mix the layers and add lots of air. This will allow the micro-organisms to work quickly and efficiently and come the season's end you will have rich, pong free, compost gold.

  • JOBS FOR THE WEEKEND: SUPPORT AUTUMN FRUITING RASPBERRIES

    Summer fruiting raspberries have now finished cropping. The canes of Monty’s autumn raspberries are vigorous and showing autumn promise. Monty likes to support his canes, making picking easier, nothing fancy, just posts and string. Once fruiting is finished, all can be easily removed and the canes cut back.
