Gardening in Waitaki July 9th 2025

Bleak winter mornings and damp, muddy conditions are keeping many gardeners indoors for now. However, this is an ideal time to plan for spring colour and begin sowing seeds under cover, where they can germinate in a sheltered, spot with good overhead light. Try antirrhinum (snapdragon), carnation, calendula (common marigold), sweet peas, verbena, cosmos, and viola. These should germinate well and be ready for pricking out into punnets before spring arrives.   New season’s roses are now available, though they’re not as popular as they once were. Many new gardeners see them as high-maintenance, and the thorns can be off-putting. But to me, a summer garden simply isn’t complete without at least one or two roses for their beauty and fragrance. Roses don’t need to be planted in traditional rose beds. If you're unsure about including them in your garden, seek out a rose enthusiast for advice on the best varieties—ones that flower continuously, have a lovely scent, fewer thorns, and are known to thrive with minimal fuss.There are roses to suit all sorts of spaces: to add a splash of colour among green shrubs, to climb a wall or fence, or to spill gracefully over a low wall—like the Flower Carpet varieties, which now come in a range of soft shades and can be trimmed with a hedge trimmer.Roses do need full sun, regular watering through summer, and a generous layer of compost in early spring and again after summer deadheading. July is the time for their winter prune—just these steps in the cycle of care will reward you with years of joy.Planting new roses: Plant below the graft section, at the bud union to the root stock, fill the planting hole with water and let it seep away, plant and firm in. Dahlias will need cutting back and mulching for protection if left in the ground. Clumps can be dug now and reduced or split up, dahlias tubers will hold in a dry place until planting out when frosts are over.  Peonies are divided in autumn and are now on offer to be planted in well-draining soil. if you think there is a chance they would sit in wet, soggy soil over winter, they may rot. Planting can continue until September.If young trees or shrubs need transplanting, now is a good time to do it, whilst they are at their most dormant stage. Fruit: Look closely at the shape of your fruit trees and plan how pruning can improve them if needed. Pip fruit should be pruned during winter. Raspberries: Pruning is best done in winter. Remove all old canes from last year's harvest; these will be brittle and need to be cut to the ground, then look for canes with healthy, thick bark and green leaves. Cut these canes back to a mitre height and secure by tying against a fence or framework. \Vegetables: On the coast, start raising vegetable seeds in glasshouses or under glass or plastic with ventilation spaces to circulate air and stop seeds from going mouldy. Plant veg seedlings now on offer, along with garlic cloves. In colder areas, sit back and let frosts work on the soil. Start sprouting seed potatoes. Early varieties like Jersey benne, Cliffs kidney, Rocket, Ilam hardy, and Maris Anchor should be sprouting now for early planting. Cheers, Linda
