Peach leaf curl is a fungal disease that distorts the leaves of peaches and nectarines, and sometimes also apricots. The leaves crumple and thicken, and often have red blistery patches. Ultimately they fall off, and if your peach tree only has a handful of leaves left, it’s obvious that it won’t perform well.

Luckily, there is a way to prevent it infecting your peach trees and that is to keep the rain off them. The fungal spores need wet conditions to germinate so covering the trees with a clear plastic sheet between November (after leaves have fallen) and mid-May to keep their branches dry will prevent infection. That’s why, more often than not, peaches and nectarines are grown against walls, to make covering them easy.
The sheeting shouldn’t form an air-tight seal around the tree, simply cover it from the top and down the front, like a mini lean-to greenhouse. Leave gaps at the sides so insects can still get in to pollinate the flowers, or you won’t get any fruit anyway and your efforts will have been in vain.
If your peach does show signs of infection, remove any leaves as soon as you spot the symptoms. If the tree is otherwise healthy, it should hopefully produce a second flush of leaves that won’t be reinfected.
If you are considering planting peaches or nectarines, there are some cultivars that have more resistance to peach leaf curl than others. Peach ‘Avalon Pride’ is said to be the best.

AS SHE OFTEN DOES, naturalist and nature writer Nancy Lawson—perhaps known better to some of you as the Humane Gardener after the title of her first book—caught my attention the other day.
London pride (Saxifraga x urbium) is a low-growing evergreen perennial, a hybrid between Spanish Saxifraga umbrosa and Irish Saxifraga spathularis. Once a great garden favourite, London pride plant is hardy and looks good all year round, forming spreading clumps of leafy rosettes made up of spoon-shaped, fleshy, mid-green leaves. In summer masses of small, pink-flushed white flowers are borne on slender stems of around 30cm in height, lasting for up to three months. London Pride thrives in most soils and situations and is especially useful for shady sites. It’s an undemanding and versatile perennial that has fallen from fashion but is a worthwhile garden plant, being easy to grow, yet not invasive. Called London pride because it flourished on bombed sites in the city during the Second World War, it’s even the subject of a song by playwright and composer Noel Coward, whose song titled ‘London Pride’ was popular at the time.

Planting ginger is easy, but you have to do it properly and at the right time if you want to get a decent crop.
This year, when gardeners look at plant and seed catalogs, I think they will be inclined to go for the safe and familiar. After all, even optimists need a sense of security. It will probably be a banner year for roses of all kinds, with reds selling well. The ongoing vogue for cottage flowers will probably continue to be strong. In fact, the wildest thing many people will invest in come spring will be a few of the more bizarre coleus cultivars.

Some people get their kicks from designer labels, others from rummaging through flea shops, or collecting obscure Japanese comics, vintage tractors, handbags, dolls, beer-mats, Star Wars merchandise or whatever else. Me, I get mine from ordering seeds.
The Blueberry is a native American fruit harvested from wild plants since the country was settled. About 1910 the late Dr. F. V. Coville of the United States Department of Agriculture began the domestication of the High-bush Blueberry. A breeding program based on selected wild types has produced through the years a number of varieties vastly superior to their wild ancestors. Considerable research on cultural problems has developed a body of knowledge on which a highly profitable and extensive commercial industry is growing rapidly.
