The record-breaking warmth and drought within the UK this summer season left our gardens fried and frazzled. And there are predictions that future years will even maintain droughts and warmer temperatures.
However nevertheless scorching or dry the long-term pattern is, we will nonetheless have unexpectedly moist summers. Final summer season there was twice the conventional degree of rainfall in my space.
So we don’t need to fill our gardens with drought tolerant crops which is able to wrestle or die subsequent time we now have a moist summer season.
So I’ve checked with some gardens I’ve identified for some years, together with my very own, to see which crops did finest on this yr’s drought- but in addition appeared good in final yr’s unusually wet summer season.
Former backyard designer and baking influencer, Jane Beedle, has a backyard which survived this summer season’s drought and final yr’s moist climate, wanting good in each. So listed below are her suggestions.
What’s the distinction between drought tolerant and drought resistance?
It’s a query of diploma. Drought resistant crops will survive very, very dry circumstances for a chronic time period. Drought tolerant crops are crops that may survive uncommon durations of drought, however will want somewhat extra water than drought resistant crops.
It’s additionally value remembering that even drought resistant crops can wrestle of their first yr.
There’s a debate within the gardening world about whether or not it is best to water perennials and shrubs of their first summer season, to assist them get established, or whether or not it’s higher to allow them to discover their very own approach.
However you usually tend to lose a plant to drought if it’s in its first summer season.

Silver birch – good in dry and damp summers
One in all my favorite timber, the silver birch, can also be advisable for dry summers. It received’t like extremely popular or humid climate, but it surely’ll be positive within the occasional moist summer season.
Silver birch may be very hardy and might survive temperatures all the way down to minus 46C/minus 50F. Silver birch is taken into account invasive in some components of North America, so verify the place you might be.
Jane purchased fairly a mature silver birch. ‘It took 4 males to hold it by way of the home.’ Nevertheless, in the event you purchase a bigger tree, you’ll have to water it properly till it will get established. Give it a great watering as soon as every week, letting at the least a watering can stuffed with water seep down deep into the soil.
Don’t simply sprinkle water on the soil. That may encourage the roots to hunt the floor water somewhat than to develop down deep.
What are the very best drought tolerant shrubs?

Fatsia japonica – the shrub that places up with nearly something
Fatsia japonica is without doubt one of the most obliging crops. It’ll develop in fairly deep shade and put up with neglect. Fatsia additionally has splendidly sculptural leaves and it flowers in winter. So it has alot to supply wildlife.
It’s not very hardy, solely all the way down to minus 10C/14F, however that’s positive in most UK winters.
Drought tolerant perennials for stunning borders
This final summer season has actually examined our borders within the UK. Some drought tolerant crops , comparable to crocosmia, appear to have suffered. However there are a number of stars in Jane’s backyard (and in mine too).

Nepetas usually are not simply low upkeep drought resistant crops. They’ll cope with actually fairly a moist summer season, too, though they received’t take pleasure in very boggy circumstances. They usually’re hardy all the way down to about minus 20c/minus 4F.
You’re typically suggested to plant Nepeta in full solar, but it surely appears pleased with partial shade in my backyard.
Perovskia ‘Blue Spire’ (now Salvia)
This elegant member of the sage household featured strongly in Doddington Place’s Rock Backyard, which has not been watered for twelve years. After the lengthy, scorching July it appeared as shiny and cheerful as ever. It has lately been re-named by the botanists and must be known as Salvia ‘Blue Spire’, however up to now, everybody nonetheless appears to be calling it Perovskia.
Salvias are additionally within the sage household – and sage is properly often called one of the vital dependable drought tolerant crops. This is a gigantic household, so you will have to verify which salvia you might be shopping for. Some are very tender and received’t even survive a UK winter, whereas others will fortunately reside for years when winter temperatures go all the way down to minus 35C/minus 30F.
Jane recommends Salvia ‘Greggii’, which is hardy all the way down to about minus 10C/14F, and which flowers for months on finish. She says that she chops it again to a small mound in late spring, after which crops round it. Yearly it grows again into a big bush, and the flowers go on for months.
Verbena bonariensis may be very standard for its tall, ethereal wands tipped with purple flowers. It’s beloved by pollinators, too. Like Salvia ‘Greggii’, it hardly appeared to note our 40C/104F heatwave.
Final summer season it was simply as fairly. And the seedheads stay into winter, feeding the birds and looking out good in frost.

Also called Dwarf Germander, has been one of the vital drought tolerant crops in my backyard this summer season. It’s a low evergreen shrub with tiny pink flowers that are beloved by bees.
I planted it about 4 years in the past and it now drapes itself elegantly over the trail. It was completely satisfied final summer season too, within the wetter climate. This candy little plant is nice in both solar or shade, so it’s a really helpful floor cowl.
Drought tolerant crops for pots
You possibly can plant any plant in a pot, and I efficiently grew salvias in pots for a season. And even in the event you select drought tolerant crops, you’ll nonetheless should water pots repeatedly as a result of the crops can’t get their roots from the soil. However these crops are much less more likely to wilt below the relentless warmth of a scorching, dry summer season as a result of they’re ‘Mediterranean’ crops.
The basic Mediterranean plant for pots. They usually are available in vibrant pinks and reds. Jane’s backyard has plenty of inexperienced foliage and with pops of color. Only one pelargonium may be very efficient.
You at all times should water and feed crops in pots, as a result of even in a moist summer season, little or no rain can penetrate a pot stuffed with flowers and foliage.
