Sow celeriac, spinach and turnip in modules early in the month. Use peat free seed or finely sieved multipurpose compost; larger seeds like peas and beans can be sown in straight multipurpose compost. Sow half-hardy annuals including climbers for ornamental outdoor displays. Like all greenhouse grown plants, they need ‘hardening off’ ready for transplanting once […]
Ideally, plants in gardens and greenhouses are designed in layers. And the most neglected layer is right at the bottom—the groundcovers. Using living plant material instead of just mulch makes for easier maintenance, and less weeding. This is true in garden beds and in containers, where shallow-rooted groundcovers do not compete with their deeper-rooted companions. […]
In the last nor’easter gale here in Rhode Island, wind gusts reached 60 to 70 mph. Usually, the greenhouse, which is in the lee of my studio, is not affected by northerly winds. But one sunny day this spring I opened the greenhouse windows to lower the interior temperature, which had reached 90°F (32° C). […]
Give your greenhouse an amazing splash of colour through late summer and autumn from sowing the dwarf Pomegranate right now. This natural bonsai is a perfect miniature of the exotic Pomegranate tree only attaining a few inches of height in a year, possibly a metre or more in a decade. Yet despite the tiny growth […]
Anyone that follows my features in the Hartley magazine, knows that I don’t usually encourage new gardeners to grow tomatoes. And that’s because they are precocious little madams that demand constant attention and care. Now I don’t mind mollycoddling plants to ensure that they perform to their full potential, but there are a few booby […]
It’s time to get sowing and growing, because spring is in the air. In the last few days, I’ve had a cup of tea in the garden, my face warmed by the sun for the first time this year. My ginger tomcat Frank has been rolling about, with his legs in the air, and this […]
One of the plants I have kept in the greenhouse all winter is wasabi. Wasabi is native to Japan and in the wild it grows in near woodland streams, on mountains, and so at high altitude. All of this works in our favour when growing it in the UK. Japan and the UK are not […]
Peaches and nectarines flower early in the year when there are few insects about, so hand pollination is the only way to ensure a good crop. It works best after two or three dry warm days when most of the flowers are open. When the time is right, there will be a dusting of pollen […]
I’m always a fan of the display gardens at Seattle’s Northwest Flower and Garden Festival because they offer inspiration for creative ideas to take home and try. This year “Dreamscapes by the Sea” featured a Hartley Victorian glasshouse with double porticos that allowed showgoers to walk right through. It was nestled into a lush garden […]
For passing wild life, a garden made in nature offers a welcoming stopover – and for the gardener, there is the joy of myriad encounters with the creatures that share our world. A gang of long-tailed tits has just swept through my garden on a tepid February breeze, lit up by milky, spring-is-around-the-corner sunshine. Darting […]
It’s cold in Cold Aston and my two lovely daughters do a wonderful Stella Gibbons act in the same sort of northern accent you get on the Hovis advert – where the young lad pushes the bike up Gold Hill in Shaftesbury in Dorset. I have trouble propelling myself up that steep hill, let alone […]
Sowing seed is the triumph of hope over experience, especially when seasonal conditions are wildly variable: Getting started takes a knock on the head as spring’s promise turns back to dour winter on a random schedule. Yet, growlights, warming pads, warm sweaters and other scientific advances aimed at greenhouse growing encourages us to get on […]
