Well, where did all that rain come from? It arrived with such force, leaving a trail of destruction across our district. My thoughts are with everyone who was affected, and I sincerely hope those impacted are now receiving the support they need and are well on the way to getting life back to normal.
Winter has well and truly settled in across North Otago. Rain and frost remind us that the coldest part of the year is here, and sodden ground means gardens and lawns will remain out of bounds until we get some drying winds. Remove saucers from under pots, as standing water can freeze, damaging plant roots and rotting bulbs, so good drainage is essential.
Although gardens appear quiet, so much is happening beneath the surface. Roots continue to grow, buds slowly develop, compost quietly matures, and every frosty morning helps prepare plants for the burst of growth that spring will soon bring.
July used to be one of my favourite months for catching up on those jobs that are difficult to tackle during the busy growing season. This year, however, many gardens will need time to dry out before we can begin cutting back deciduous trees and shrubs. While we wait, it's the perfect opportunity to plan for the busy spring and summer months ahead. Keep an eye on areas of the garden that drain slowly, particularly where heavy clay soils are a problem. These spots may need some intervention to prevent ongoing waterlogging. Digging shallow drainage channels can help remove standing water or redirect excess water to a lower area where it won't cause problems.
Bulbs, tubers and plant roots can quickly rot if left sitting in saturated soil for too long. If you're concerned, lift dahlia tubers and any valuable bulbs, pot them up, and keep them in a sheltered spot until the garden has drained enough for replanting.
Rose pruning: As I mentioned last week, rose pruning is best left until August, when the wood has had time to firm up. Ideally, pruning should be completed before the buds begin to break.
Planting and transplanting: Garden centres are now well stocked with bare-rooted deciduous trees, roses and fruit trees. Make your selections before the best varieties sell out, but wait until the ground is no longer wet or frozen before planting. Trees and shrubs will happily remain in their bags for a while if kept watered. Before planting, always read the label carefully and consider the mature height and spread of the plant. A small shrub today can become a very large tree in years to come.
Vegetable garden: Wet winter soils are best left alone until they begin to dry. Once workable, dig over vacant beds and incorporate generous amounts of compost and well-rotted manure, as heavy rain will have leached nutrients from the soil. Then allow frost and worms to continue improving the soil structure before spring planting. In colder districts, garlic can be started in containers if the ground remains frozen. Coastal gardeners can continue planting garlic into well-drained soil.
If you grow early potatoes, have them ready to plant once conditions improve. Now is the perfect time to chit them by placing seed potatoes in a cool, frost-free, well-lit position to encourage short, sturdy green shoots that will establish quickly once planted.
Gardeners with a greenhouse or cold frame can begin raising early vegetable seedlings ready for spring. Comfrey remains one of the most useful plants to have in the garden. Its potassium-rich leaves make an excellent compost activator, liquid fertiliser and mulch around tomatoes, beans and other fruiting plants.
Fruit garden: Buy deciduous fruit trees and berry bushes while they are on offer, then plant when the ground allows. Choose sunny positions and avoid frost hollows for early-flowering varieties such as plums, pears and apricots.
Resist the temptation to prune peaches and nectarines during winter. These are best pruned in early spring as growth begins, allowing wounds to heal quickly and making it easier to see which flower buds have survived winter. Cherries are best pruned during summer on fine days to reduce the risk of silver leaf disease.
Apple and pear trees respond differently to heavy winter pruning. Excessively hard pruning often produces masses of water shoots and leafy growth at the expense of fruit, so vigorous trees are often better managed with summer pruning once the leaves have fully developed.
Prepare new strawberry beds whenever conditions allow. To maintain healthy, productive plants, replace old beds every three years and renew the soil where possible. When propagating from runners, always select the runners closest to the parent plant, allowing them to root well before separating them in early spring.
