Britain is
seeing evidence of climate change in the garden and we are getting drier,
hotter summers. Lots of our customers are interested in growing drought-tolerant
plants and there are numerous plants that can tolerate dry conditions and make
excellent colourful garden features. Now these plants have developed ways of
coping with drought conditions – including fleshy, hairy or waxy leaves,
silvery or grey leaves and even reduced thin grass-like leaves or thorns. So this
means good plants include Ceanothus, Ceratostigma, Cistus, Cytisus, Euonymus,
Hebe, Lavender, Rosemary, Red Hot Poker, Catmint and Sea Holly among many, many
others. What you need to bear in mind though, is that nearly all of them only
become drought tolerant once they are established. So, it’s important to water
them in well after planting - giving one good soaking every week or so rather
than little and often - to ensure they become established as soon as possible. Applying
a thick mulch of bark, cocoa shell or gravel after planting will help insulate
the roots from hot, sunny conditions and maintain soil moisture levels. But it’s
important to ensure the mulch is only put down when the soil is already moist. Also,
don’t forget that planting membranes can also be used to help keep moisture in,
too and you could even add water-retaining gels to the soil.
