Although greenhouse tomatoes have so far seldom been devastated by Blight to anywhere near the same extent as outdoor crops this seems worryingly on the increase. To say little of wilts, rots and the dreaded Mosaic virus. (Interestingly though Mosaic virus infections have decreased with the decline in smoking ie handling tobacco was the source). […]
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 […]
I have some small lettuce seedlings that I started in the greenhouse and it is time to plant them out and get some summer salads going. The weather has been so very wet here in the southwest of England this spring that the garden is well behind, and the only work that has really occurred […]
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 an increasingly chaotic, frenetic world, we need to find a still centre – and for greenhouse gardeners, there’s one safe zone where we can be sure of feeling grounded. It’s all a bit too much, isn’t it? Too volatile, too costly, too unpredictable, too unsettling, and without a doubt, at times, too downright nasty. […]
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 […]
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 […]
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 […]
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 […]
