Put up-drought, gardens will want a postmortem. As but, it could be too early, not simply in case dry climate returns however as a result of a few of the deaths won’t present for some time. I effectively keep in mind 1976, that dry British benchmark: a few of the casualties have been lifeless by October however others confirmed full harm solely in spring 1977. We could also be in for some nasty surprises. I’ll put together for them right here with balanced observations; first some excellent news, then some dangerous.
Even on the most popular days, geraniums in pots have flowered excellently. Botanically they’re pelargoniums however their appropriate title has by no means caught. Why will we stampede after novelties for our summer season gardens? Scarlet geraniums, watered every time potential, have been spectacular, simply once I had been seduced by pendulous apricot-flowered begonias on particular supply.
Begonias should have flourished in warmth, although they have to be stored as moist as potential. I wetted mine dutifully, considering of the principle greenhouse in Lyon’s botanical backyard, the place the begonia assortment is a speciality and the water drips sub-tropically. Maybe I typically watered them too late within the morning. The sides of their leaves scorched and the flowers do that column no credit score.
One of the best pink “geranium” is straightforward to recollect: it’s Finest Pink, obtainable in spring from Suttons or Thompson and Morgan as younger vegetation. On the RHS web site I flicked via their really helpful pelargoniums and located all the flowery variations: angel ones, stellar-flowered ones, ivy-leaved ones and even Dolly Varden, whose leaves are zonally marked with a darkish ring. They’re good, however they don’t seem to be practically pretty much as good as Finest Pink, which the RHS omits. Finest Pink has clusters of scarlet flowers, borne in profusion for months on finish.
Here’s a trick which it should like: give it weekly feeds of a liquid fertiliser that’s wealthy in potash. An affordable one is Tomorite, which incorporates twice as a lot potash as nitrogen and phosphate. As a tough information, potash promotes flowers, nitrogen promotes inexperienced progress and phosphate promotes roots. If the bottle says Tomorite is for tomatoes and fruit, ignore it; skilled growers use it freely on flowering vegetation.
Now for a spectacular failure: spinach. It insists on wealthy damp soil and on my dry Cotswold cinders it has been ineffective. Final week I mentioned my battle with Raymond Blanc’s mussel mousse in a watercress jus. Buoyed up by success, I learn on since to web page 201 of the maestro’s Cooking for Associates and reckoned the spinach mousse might be my subsequent coup.
The issue? Whole failure of spinach within the backyard. I had to purchase bagged “child spinach”, so-called. It was leafy beet in disguise: English spinach ought to have darkish coarse leaves. As Blanc warns, “some styles of spinach have little or no flavour”, and my child beet had none.
His mousse d’épinards rises completely, however the principle ingredient’s model title wants policing. Right here I’ve a suggestion for the subsequent Tory PM: there’s a downside of what to do with Jacob Rees-Mogg, so why not make him Minister for Spinach? As a substitute of tearing up each Euro-rule in sight, inform him to kind French beet from British spinach and use regulation to guard a nationwide model. Then I’ll sow it once more subsequent yr, hoping for the rain it requires.
Removed from being the Superb Twelfth, August 12 was a horticultural nightmare. It overheated and after six dry weeks was very practically the ultimate straw. By no means hand over, even when a second wave of warmth arrives: gardening is a course of, not a fast repair.
On the inglorious twelfth, I observed that my daphnes have been all unbothered. They’ve strong evergreen leaves and, not like verbenas, have by no means scorched. There are a number of new winners on this household, however I give 5 gold stars, even this yr, to Daphne Everlasting Perfume. It’s value each penny of its highish value because it has small white flowers for months from June onwards and may be very sweetly scented. In an enormous pot it’s glorious: strive one on both aspect of the entrance door. If you’re away throughout the week and can’t water, they’ll survive.
Rhododendrons, in contrast, have begun to look depressing. Their leaves are shrivelling and drooping or dropping, however right here a protracted view is greatest. In 1976 they have been hit even more durable, however they bounced again when rain arrived and flowered effectively in 1977 and thereafter. They’re nice survivors, so don’t despair in case you are taking a look at a rhododendron mess.
Phloxes have shrivelled too and peonies and aquilegias are scorched. They’ll all come again subsequent spring, as will primroses: water them every time you may and don’t write them off.
What about dahlias, often mainstays any longer? Mine have survived, however not totally developed, though I’ve canned them with water each night. Most of the decrease leaves have turned green-yellow after days as sizzling because the twelfth. My schedule now’s to place them on medication. I’ll give them one dose of diluted Miracle-Gro as it’s excessive in nitrogen and should encourage inexperienced progress. Then I’ll revert to weekly Tomorite to encourage flower-buds. Use it at half power on white-flowered dahlias because it can provide them a brown flush in any other case.
What about roses? To my shock, they’ve seldom dropped all their leaves. Even in slender beds in opposition to a home wall, they’ve stayed contemporary with out watering. Among the many winners for inexperienced neatness in drought are the Scots Burnet roses, Rosa pimpinellifolia. They flower solely as soon as however they make rabbit-proof, drought-proof thickets about 3ft excessive and broad. The double white-flowered ones are the most effective. They’re used to life close to the sandy seaside.
White-flowered gauras are positive too: with pale blue-flowered perovskia, the Russian sage, they have been my mainstays within the dry Nineties and must return in amount. Crocosmias, nonetheless, have been a shock. These planted throughout the previous three years scorched badly on their lengthy, lance-like leaves. I’ve to hope that Crocosmia Hellfire, an outstanding darkish pink, will come again from brown shutdown subsequent yr.
For recommendation, I’ve been trying again on the first version of The Dry Backyard by Beth Chatto, whose dry Essex backyard, like this e book, has remained well-known. Even in 1978 she described her shock at discovering a big lone clump of frequent montbretia, cousin to my crocosmias, “throwing up a lovely fountain of grassy leaves, shades of russet brown, glistening within the low rays of the solar”. I assume the browning was from warmth.
I can’t bear to debate timber; sorbuses hated the warmth, birches hated it too. One lesson from drought is that close by vegetation of the identical selection will survive otherwise. I might have thought blue-flowered evergreen parahebes have been unscorchable however I’ve two, one a yard from the opposite. One is inexperienced and comfortable, the opposite is burnt nearly to extinction. Like nature, cruellest of moms, drought strikes in an unpredictable method. One of the best recommendation continues to be to attend and see.
