In the rose garden with Ludwig
Our roses responded amazingly well to the temperature variations experienced during July and August in Gauteng. Nights were cold and hovered around zero degrees. The days quickly warmed up to 25 and even 30°C with cloudless, blue skies. The plants responded to this ideal weather excellently. Many are almost ready to open their first flowering buds.

These roses were the first to be pruned and they are developed the furthest.

These buds will start to show colour very soon.It is indeed the first time ever that I have experienced that on Spring day our roses in Pretoria are considerably further advanced than those in Durban / Hillcrest, Natal. They have experienced an unusually cold winter.

Due to the cold, the roses in KZN were far behind Pretoria’s.Roses are adaptable and that is part of the fun of having roses in your garden with the expectation of observing their growth and first flowers.

Over winter we carried on replacing some of our very old mother stock. We dug deep drain trenches, and raised the beds with fresh soil that is enriched with our compost, manure, peanut shell mix. They are already showing a great willingness to show off this October.

Even the roses planted in June are showing super new growth!
I travelled to Germany in the last week of August for a family re-union, but of course also went around to visit and look at roses.

Two months of no rain and temperatures into the high 30’s is a new experience for farmers, nurserymen and gardeners in Europe.

Few have irrigation systems, as we know them on farms and gardens in SA, installed.

Again the roses adapt. Many are suffering and have lost their leaves. They simply toughen up and wait for better times.

But, those that were watered regularly are responding by starting a third flowering cycle. They have grown as tall as we know them to do in our climate.

It was interesting to walk through the hip bearing rose types at the Sangerhausen Rosarium. As it was almost the beginning of Autumn and the roses were stressed by the hot and dry conditions they carried many hips, hundreds of different ones. Each variety with its own unique colour, size and shape.

Apples, Pears, Plums and Walnuts were all over-laden with fruit. This is of course due to the abnormal weather pattern Europe has experienced this summer.

Farmers explained how difficult it was for them to prepare their fields after the grain harvest. They have not ever had to do so in totally dry soil as is common practice in South Africa. They hope to sow Canola once the rain eventually comes.

Watering
It is impossible to give a general recommendation that will suite all garden situations. The position, the type of soil and the climate need to be taken into account.

The one important aspect is that the water needs to get to the roots of the roses and be able to drain further down.

Roses like water in motion. If the application is by irrigation system, one needs to check that at least once a week it delivers around 15mm of “rain”.  This can easily be checked by placing a rain gauge into a rose bed.

Time how long it takes the sprinklers to bring it to that level and you will know how to adjust your schedule accordingly. 15mm of rain is the equivalent of spreading 15 litres of water over 1 square metre.

Pouring 10 litres of water to a rose by hose or watering can would be the equivalent. The water actually needs to penetrate to the roots and not run off.

Watering daily with less water in-between is not a problem and especially on hot summer days is most welcome.

Overhead irrigation, wetting the leaves is not a problem at all. It washes the dust off. It will not cause fungal infection, since the water on the leaves would have dried up long before the spores of a disease like black spot could have germinated in it.

The same applies to the time of day they are watered. It is of no consequence if it is in the early morning, midday, evening or even at night.

Spraying
The new, lush foliage is an attraction to aphids and thrips. It is the best time of year to drench with KOINOR now in September.

It takes virtually minutes for the toxin to be absorbed by the roots and pushed up into the bush and to the leaves. Sucking insects soon drop off the buds and are then mostly prevented for an extended period.

Watch this short video to see how easy it is to apply Koinor.F1 Aphids a day after treatment with koinor.jpg

Note how the aphids are drying up after an application of Koinor.To prevent fungus diseases it is necessary to spray. At this stage of rapid growth it is best to do so fortnightly. Our cocktail consisting of the eco-cert INSECT SPRAY and the translaminaire fungicide CHRONOS with the adjuvant PICANTA gives very good control.

The cocktail controls the moth that lays its eggs onto the sepal of the green flowering buds from which ball worms hatch. They eat their way into the developing blooms and leave holes in every petal that become visible as the bloom opens.

CHRONOS is absorbed by the leaves and protects them from the inside. New leaves developed after the last spray are exposed to fungal infection and it is best to repeat the spraying every two weeks.

Alternating the cocktail with ROSE PROTECTOR has also shown good results.

Fertilising
It is best to have dug and mixed compost, manure or organic nutrients including our controlled release VIGOLONGER fertiliser into the soil around the roses after pruning. This will provide excellent sustained growth.

Roses, like most other plants, react quickly and favourably to extra nutrients from dissolved fertiliser granules. It is astounding to observe how a week after applying VIGOROSA fertiliser, the leaves become larger, the stems stretch considerably and how finally larger blooms are produced. The little scoop of 30g spread around each bush now in September is sufficient.

Finger Pruning
Finger pruning is mainly carried out on the Hybrid tea and Antico Moderno roses and very much so if the intention is to pick most of the blooms for home decoration.

The clusters of Floribunda stems provide flowers and colour for so much longer as the blooms on the cluster are in different stages. Finger Pruning them is not needed, however, it could be carried out to even out the flowering.

The leaves of the spreading colourscape types i.e. ‘My Granny’ and the Fairy Tale varieties are naturally exposed to sunlight and create their own space for flower development.

The finger pruning methods have multiple advantages.

It provides green leaves quicker and with it improved photosynthesis and improved root activity.

The flowering cycle is dispersed and easily maintained throughout the flowering season.

It encourages sprouting of basal stems and also extra growth from lower parts on the bushes.

It entails the pinching out of the very tip of the new shoots. The best stage to do so is before the flowering bud is visible.

Even when early buds have already formed and the ideal stage has passed, pinching can still be carried out. One can then easily tell which stems are favoured and will become nice blooms – those are left unpinched. Of the other smaller, weaker stems, the small green bud and the upper two leaves are broken out with your thumb and index finger.

Mostly one selects about a third of the new shoots and pinches them. So if there are a total of 12 new buds being formed, you pinch 4 of them.

Basal or water shoots are thick and soft and easily break off completely in windy conditions. These shoots become the best new flower producing stems. By topping their tips off when they reach about knee height, they become green and form wood. Once they have hardened off, they re-sprout with the most perfect blooms.

Even though the whole finger pruning procedure sounds intricate, it is not.

Simply watch this short video that explains the concept
by showing you how it is done. 

Disbudding is carried out on the Hybrid tea roses when the intention is to pick the blooms for the vase. It entails the side way pulling out of side stems and buds from the leaf axels beneath the main terminal bud.

ROSE of the MONTH: St Dunstan’s Centenary KORwintori(P)St Dunstan.jpg
This beautiful rose was named for the centenary celebration of the St Dunstan College in Benoni.

It is related to the world famous ‘Peace’ rose. It shows off with glossy green foliage. The admirable blooms start off with high pointed yellow buds that slowly unfold to reveal a multitude of inner petals which take on a sheen of pink. The half open blooms have an intriguing, nostalgic deep cup shape.

They are borne on strong upright stems and remain fresh for a long period on the bush or when cut for the vase.

The mature bush stands proudly upright up to a height of 2 metres. They are ideal in mixed rose beds, as screening of fences or in groups of three as a focal point in a garden.
