Like Daltons Ltd on Facebook Q My viburnum hedge is dying, the leaves are going fawny gray with little black dots over them. I have used an aphid and mite spray and sprayed them 4 weeks in a row to no effect. Any new leaves look wilted and curling up. Normally they would be in flower now. Is this aphids? Congratulations! Today’s winning question came from Paul. It is possible from your description that your A viburnum hedge has been heavily infected by thrips during the past summer. Thrips are a very very small insect that attack many plants en masse. While spraying can kill the thrips, the symptoms will remain on your leaf until they fall and are replaced in the growing season. The symptoms of thrips are visible on the upper side of a leaf by a grey silvery colouring, while on the underside of the leaf, a brown and sometimes sticky appearance is very obvious. While viburnum can make an attractive hedge, in the short to medium term, as the plants reach an age of 10 years and more, they tend to become woody and the leaves often smaller and stunted in appearance. To extend the life of your viburnum hedge, regular clipping over the summer months as well as fertilising with a garden fertiliser and deep watering when extended dry spells are experienced, will all help maintain your hedge in healthy condition. If your hedge appears in poor condition it may well be advisable to replant with another species that may be more suitable for your specific conditions. Your local garden centre can help with your selection.

If you like picking your own fruit – try feijoas FEIJOAS ARE an excellent plant in the home garden. They make a great fruiting hedge, attract birds to the garden and are easy to grow with the added bonus of delicious fruit. Feijoas are an attractive evergreen plant ranging from a shrub to a small tree, which will grow between 2-4m in height. They are easily trimmed and maintained and have a green leaf, which is grey underneath. Feijoas have pohutukawa-like flowers in December and fruit mainly from April to June. Feijoas generally prefer a warm place in the garden and young plants need protection. The soil needs to be well drained and rich in organic matter. The plants shouldn’t be allowed to dry out in the summer months as this will hamper fruit production. Feijoas are heavy feeders. Feed them with sheep pellets and a high-nitrogen general garden fertiliser in late winter. Also apply a slow-release fertiliser throughout the growing season. The self-fertile varieties need only one plant to fruit. Non self-fertile varieties need other varieties planted near them, so it pays to plant three or more for heavy crops. They will fruit on their own but the crop is minimal. Feijoas fruit on new season’s wood, so prune for shape without removing all new wood off the plant. Feijoas can be made into many interesting shapes with pruning. You can train them as a small tree with a single trunk and then branch from there, and they make great hedge plants. Feijoas are a must for anyone who enjoys picking their own fruit. ATTRACTIVE: Tasty fruit and colourful flowers.

Hunt out old gardening books or take a trip to the library for ideas and inspiration. Gather up seed catalogues as they come in and mark off what crops you would like to try next season. It is a good time to do a stocktake in the garden shed and check over garden tools and do some maintenance. And while you are at it, check those seeds you have saved earlier on to make sure they are not mouldy and label them clearly so you know what they are when you find them in the drawer next spring. GARDENING GUIDE Roses To ensure our roses give us the best performance and plentiful blooms for the following season, we must brave the cold and tidy up, mulch, spray and prune our somewhat scraggly and, by now, bare roses. Planting: Roses like sun for at least one third of the day, and some air movement. Deep digging helps drainage, aeration and loosens the soil for easy root penetration. Mix in compost to improve the soil condition and add a handful of ‘Blood & Bone’. If you’re replacing an old rose, it’s well worth the effort to dig out the old soil too. Dig the hole large enough to create a mound in the bottom so that the roots can be spread over it, ensuring it is deep enough for the graft to sit just above the soil. Do not apply fertiliser at this stage as direct contact with fertiliser can kill tender new roots. Space your plants about a metre apart, slightly more for very vigorous varieties, and two metres apart for climbers. Remember to keep your rose well-watered for the first six months as it becomes established. Pruning: Rose flowers are produced on new season’s growth, so by cutting-out dead, diseased wood and reducing the stems you will get strong new growth and lots of flowers. As a guideline prune between ⅓ to ½ of the growth on bush roses and ½ of the growth for floribunda. Remove all spindly weak intertwining branches, especially those that rub up against one another or are too crowded, cutting just above a bud always on an angle pointing in the direction in which you wish the stem to grow. You should aim for 3-5 healthy canes. With standard roses cut to an outward growth to maintain a beautiful shape. Climbing roses are pruned lightly in winter and given their main pruning after flowering (spring/summer) removing old and dead canes and shortening what remains. Spraying: In winter, spray with lime sulphur, which encourages the defoliation of leaves as well as keeping the stems free of scale, moss and lichen. In a further three weeks apply a copper and oil spray to help prevent scale, red mite and fungal problems. Fertiliser: Winter is the optimum time to add garden lime or dolomite lime to keep your soil sweet. After August add half a cup of fertiliser to each rose and reapply at three monthly intervals (excluding winter).

Growing together since 1929 VEGETABLES Dig up any potatoes still in the ground, especially in areas where the soil can become soggy over winter. Mature potatoes that sit in moist soil will resprout and become inedible. The skin on pumpkins and gourds will be tightening up to protect the flesh over months to come; leaving them outdoors to soak up a few frosts will help sweeten the flesh. Remember always to leave the stalk or handle on pumpkins when harvesting. Plant broad beans before it gets too cold. These do need a spot away from strong wind or maybe some stakes to support the stems. FRUIT Do you have a favourite fruit that makes you smile or even salivate when it ripens each year? At the moment, go-to fruits are feijoas and the New Zealand cranberry (Chilean guava). These highly aromatic and hardy evergreen fruits can be grown in orchards or planted as ornamentals in garden borders, both coping well with trimming. When picking feijoas leave them to fully ripen on the tree, waiting for them to fall on the ground is the easiest way to harvest them. SASANQUA CAMELLIAS Furnished with flowers at this time of year, keep sasanqua camellias looking sharp with a drench of Seasol to keep the root zone active and vibrant. Camellias do cope with some sun, but just not intense all-day sun and dry soils, so they are a good option for adding street appeal to the drive or roadside. New season’s plants are filling the aisles in the shops. Fertilise with acidic plant fertiliser. Try underplanting with azaleas or something frilly, like heucheras, or a combination of both.
