100% NEW ZEALAND OWNED AND OPERATED Kea (Nestor Notabilis) 24 Tuesday July 12 2016 Gardening SELWYN TIMES Don’t let frost get to your pruned roses THERE IS more written about pruning roses than almost any other aspect of their care. Yet, why do we prune our roses? Here are a few key reasons: Encourage new growth and more blooms. Maintain the health of the rose by removing old wood, improve air circulation within the bush. Maintain a specific shape, especially for climbing and pillar roses, and those that are pegged down. Not all roses have the same need to be pruned, some just need an annual “going over’’ after flowering to remove the dead wood. Other roses, most notably the highly bred hybrid teas and floribundas, need regular pruning. If you garden on a light, sandy soil then prune your roses only lightly as they will not be able to support the vigorous new growth that hard pruning encourages. The time to tackle pruning is in the winter while they are dormant, before they burst into growth. In some areas of New Zealand, and in some seasons, there may seem to be almost no period of dormancy and so you must choose your moment carefully. So do not prune when PRISTINE: Hard pruning roses will produce more vigorous new growth. there is still a risk of severe frost, as any new growth will be frosted and die back. You will have to cut back to the next bud, reducing the plant further. Most bush roses flower on the current year’s growth. A hard prune will produce more vigorous new growth. Remove the oldest cane on the plant; this keeps the bush fresh and vigorous. Then reduce thick, strong stems by about half their height. Thin canes need to be cut back to onethird their height. Try to keep the centre of the plant open. A mess of spindly, twiggy growth in the middle of the plant restricts light and air circulation, encouraging disease. Thinking of Landscaping?

SELWYN TIMES Tuesday July 12 2016 25 Time to plant deciduous trees GOING INTO the middle of winter, air and soil temperatures are low, the soil is often very wet, and frosts are in many parts of southern New Zealand. July is the main month for planting new deciduous trees, shrubs, fruit trees and roses, and garden centres are now fully stocked with these plants. Always select high quality specimens and plant correctly with plenty of compost into the existing soil. In the vege patch, continue planting and harvesting broccoli, brussel sprouts, cabbages, cauliflower, silverbeet and spinach. Where soil conditions allow, you can start preparing the vege garden for spring planting. In late July, chop up and dig in green manure crops like lupins or mustard. If you have roses, complete your annual pruning, especially on bush or standards that produce flowers late into early winter such as Icebergs. Remove all dead and weak growth, clean out the centre of plants and prune to outward facing buds. Add fresh compost to the soil around the rose plant, but do not fertilise until spring arrives. In warmer, sheltered areas, citrus production should be in full swing, with clementine mandarins, lemons, limes and navel oranges all now maturing. Check your trees while picking fruit for any overcrowding or weak branches that should be removed. Check for any root stock growth and prune where required. For colder climates, use frost cloths to protect frost tender citrus. Give fruit trees a second winter clean up. Spray with a copper compound or lime sulphur to kill any overwintering fungal diseases. Now’s the time to prune your blackberries, boysenberries, loganberries, or raspberries. Cut out all old canes and any weak spindly growth. New season strong canes should then be tied up on wires or fences to help support this summer’s fruit crop. Complete your strawberry plantings this month. Purchase new plants or obtain young plants (runners) from the previous season strawberry plants. For the home garden, plant at least 20 strawberry plants to ensure plenty of fresh strawberries for the whole family. Your hydrangeas may be starting to look a little sad. They can grow very large and require heavy pruning and thinning. Remove old wood completely as there will be ample new growth in spring. Make sure you cut just above a node as it is from here that spring growth will appear. Flowering winter shrubs like azaleas, camellias and rhododendrons will provide lovely colour in your garden. Take note of what varieties or species are performing best in your garden or in neighbouring gardens for next year’s new planting. Winter flowering annuals will be at their very best in July. Primulas, violas, pansies, calendulas and cinerarias should all be in full bloom. Continue to dead head from these plants to encourage continual flowering. BOUNTY: If your garden is sheltered, citrus production should be in full swing. VIBRANT: Continue to dead heat winter flowering annuals. gardening without guesswork Question: Answer: Thanks to charlotte for her question. I want to try and grow some seed potatoes this year, what do I need to do to prepare the ground, and how do I plant them? Yum! Freshly dug potatoes out of your own garden – you will love them! Here are some tips for you. 1. Choose an area to create your garden if you haven’t done so already. Make sure it gets the sun! Dig through some Organic Compost and Sheep Pellets. If you are planting them in pots, make sure you get a good quality mix! 2. Spread the seed potatoes out in a dry area and allow the sprouts to develop to approximately 1 to 2 centimetres in length. 3. Planting: Create a trough - ideally in a sunny sheltered area - roughly 15 centimetres in depth and add Intelligro’s Potato Fertiliser at a rate of 200g per square metre. Mix into the soil. Fill the trough with the fertilised soil back to 10 centimetres high. For pot planting, make sure they have good drainage. 4. Place the seed potatoes 25 centimetres apart in a row with the sprouts pointing upwards before gently covering with the remaining soil. 5. Continue to mound the soil around the potato plant as it grows to around 5 to 10 centimetres high, as this will protect the potatoes from greening and insect damage. 6. Once harvested store in a cool dark place to retain their freshness. for more information, check out our website: www.intelligro.co.nz or visit our facebook page: www.facebook.com/igro.co.nz QualITy prOducTs frOm ThE WEB TO ThE shEd!
