May is the perfect month to plant those slightly tender, late performers such as salvias, penstemons, fuchsias and pennisetums, because they need to develop good root systems before winter arrives. All too often, nurseries sell these late-summer jewels in autumn when they look magnificent. However, there’s not much chance of them overwintering if they’re planted […]
If your greenhouse will overwinter Pelargoniums then it’s perfect for Heliotropes, members of the Borage family, mostly introduced from S. America in the 18C. The European Heliotrope was thought by the Ancients to turn its flowers to catch the sun thus the name. However the massed flowers of H. arborescens, Cherry Pie do not move, […]
Will you opt for a classic deadwood construction, or get creative – even weaving in living elements for the long term? Either way, a dead hedge is a win-win for your garden and its wild life. Angry autumn and winter storms harried and toyed with my garden’s boundary fence, leaving sections of it weakened, wobbly […]
It’s a busy time in the greenhouse. Sow courgettes, climbing and dwarf beans, chard, beetroot, salad onions and tender herbs including basil and coriander. ‘Harden off’ and plant outdoor pumpkins, melons and tomatoes and courgettes in their permanent positions once the danger of frost has passed. Plant courgettes into organic rich soil, trough slits in […]
One of the most effective ways to generate a multitude of plants is to grow your own from cuttings that will get a good start in the greenhouse. This month, I’m talking with Nancy Connolly Blum, a professional landscape gardener and former owner of the Sawmill Ballroom Lavender Farm in Oregon. Here are the propagation […]
Now that it’s spring in New England, it’s time for planting in the garden the vegetables and flowers that I started weeks ago in the greenhouse. But to do this, I have a special concern. Compared with inland temperatures, my garden in spring is significantly cooler due to winds that blow directly across the still […]
Three days from now it’ll be Earth Day 2024, and thoughts turn to the climate, which of late can be described–at best–as uneven; right now, snow is forecast for tomorrow, but on Earth Day, the sun will shine, and the snow will water the garden as it melts. My one lonely daffodil will be pleased. […]
I picked up a copy of The Times the other day to be met by a headline declaring that the wet weather we’ve been having is affecting our mental health. Yes, we are all feeling under the weather Mr Times, but we’ll all recover once the sun shines again. And so will my garden. It’s […]
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). […]
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 […]
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. […]
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 […]
