RHS top 10 tips for caring for your garden in hot dry weather

With the recent wave of hot, dry weather across the UK you might have noticed your garden starting to wither. RHS Chief Horticulturist, Guy Barter, has some top tips for caring for your garden at a time when water is at a premium. Read more about making your garden more drought resistant

  1. Trees may shed leaves indicating stress but it is seldom fatal. Established shrubs, roses and climbers don’t usually need watering either.
  2. Consider re-using water from your home. Wastewater from the kitchen, baths, basins and showers is suitable to water plants and containers.
  3. Water newly planted trees and shrubs as a priority. Ensure the root ball is wet, checking with a trowel if necessary.
  4. Where planting is essential and can’t be delayed; puddle plants in, fill the planting hole with water (or better, ¼ strength liquid fertiliser) and allow to drain several times before setting out plants.
  5. A good soak, to wet the root zone, every 10 days in July and 14 days in August is best. Watering little and often is generally more work, less effective and wasteful of water. However, a ‘good soak’ can mean the equivalent of four 9L / 2gallon watering cans per square metre / yard.
  6. Move small pots and hanging baskets into the shade. Suspend hanging baskets over a potted plant so run-off water gets used.
  7. Lawns may brown, but although the leaves die the grass remains alive, ready to regrow once the rain returns. So watering them is not essential.
  8. Greenhouses, conservatories and polythene tunnels easily overheat. So boost shading and even remove some panes of glass to reduce temperatures.
  9. Target water where it is most needed. Camellia and rhododendrons lay down buds in late summer, so a good soak every so often then will help.
  10. Warmth will speed up composting so there should be plenty of excellent compost this winter. Add some water, however if the mix looks dry.


RGS members consultation update

Wisley Garden opens a new welcome centre

The RHS has opened it’s new ‘state of the art’ welcome building, which includes a cafe, restaurant, shop – including botanical bookstore and a new plant centre.

Watch the opening here

The plant centre is stocked with an amazing array of plants, showcasing British nurseries. At the opening on 10th June the RHS ambassador Alan Tichmarsh spoke about their important contribution to our horticulture.

Alan Tichmarsh said “Millions visit Wisley every year to be inspired by the horticulture on display and now the RHS flagship site will be a permanent showcase to celebrate specialist UK growers….. These plant specialists lovingly grow the rarest, most unusual and beautiful varieties in the world, which thrive in UK gardens because they’re so used to our climate….. I promise to help Greening Great Britain by continuing to promote and buy from specialist UK growers. If the UK’s army of 27 million gardeners were to do the same, we would be protecting the UK from pests and diseases coming in from abroad; helping pollinators which need a diverse range of plants in order to survive; and supporting this vital industry that is worth more than £24 billion to the UK economy.”
