In the Rose Garden with Ludwig
Presenting 12 pruning demonstrations in July gave me a chance to see and assess the performance of roses in the various regions. In all provinces, there has been a shortage of water and a very warm winter, so far. It was quite evident that rose bushes which had been able to retain foliage during the hot summer coped pretty well and were still in bloom because the leaves gave power to the roots. Very old, mature rose bushes obviously survived as their roots were settled deep into the soil.
‘Esther Geldenhuys’ grew 3m high and should only be pruned lightly, even with scarce watering such a formidable bush has deep roots

These ‘Pernille Poulsen’ on Atterbury road were planted over 30 years ago. At the time these beds were excavated to 1 meter depth and filled with good enriched soil and the roots were able to grow deeply

The Durbanville Rose Garden is ready for new plantings. The best performers have been kept.
The most common question was whether to prune or not to prune bushes that are still flowering. No doubt, by the end of July they should have been pruned. However, only yesterday I was standing next to a group of our new ‘Afrikaans’ roses and started to doubt my own advice. Is this a truly evergreen forever flowering variety? It has a very broad growth habit, the super glossy leaves have no sign of black spot and it still produces new flower clusters deep into winter. I have pruned one and left the other unpruned. I will watch them both carefully and obviously report on the results.

I have just read, with great interest, a new use for roses. Over the millennium, rose petals have been used to make rose oil and perfume, rose roots and hips are processed for medicinal purpose, and there is the obvious ornamental value of roses as cut flowers and plants. At the Technology Centre of Sun Energy in Karlsruhe, Germany, researchers have found that by copying the surface structure of a rose petal from the variety ‘Uncle Joey’ known as ‘Red Mountain Peak’ in South Africa, they achieved a 12% percent increase of light absorption in photovoltaic cells. It has to do with the Micro – Nano structure of the petal epidermis. We better start propagating this variety again – just in case.
Autumn roses are big, ‘Red Mountain Peak’ more so than others. My grandson Xavier admiring a bloom.
We are busy finalising the compilation of our new catalogue. You can look forward to some exciting new releases!

Step by Step Rose Care for August
In last month’s Talking Roses, I gave detailed advice on how to prune the various types of roses and there is also a useful YouTube insert on pruning on our website.
Pruning Climbers is tedious and time consuming and they are usually kept for last, like this ‘Crème Caramel’ in our sales area, still flowering on this last day of July.

the old wood does not look like it will give any new growth and needs to be cut out
It is obvious that the espaliered canes have become far too dense and the older branches are not well supported anymore and should be removed. Easily done by cutting them bit by bit and pulling them out.
After having pruned and removed too old branches and shortened or cut off the little flowering side stems it is now easy to tie them in the required position.
Then one can easily espalier the stems onto the arch with stretch ties again. One almost spirals some of the canes on the uprights and over the arch. If leaves are retained at the highest point of climbers it does not cause a problem.
As stated above, if you have not yet pruned the roses, it is time to do so now. Many regions had good rains and a drop in temperatures this week. As soon as it warms up the roses will sprout. It makes sense to put all the energy into the upper eyes of the pruned stems rather than in lots of little twigs with little or no sprouting at the base.
It needs to be appreciated that roses are deciduous –shedding their leaves annually, usually falling off at maturity or blaar wisselend in Afrikaans. This is really a mechanism plants have developed to withdraw water out of the leaves and stems, so that it cannot freeze and cause damage in frosty weather.
We do not experience such a cold winter and the leaves will not always drop off. They will however be neglected by the plant and become a host for various invasive insects such as spider mites, thrips and aphids.
Another reason why old leaves should not be left on the plant after pruning is that they continue making sufficient food and the rose gets ‘lazy’ so that in spring it does not convert the stored starches into sugars, carbohydrates and hormones, which then delays the sprouting of new flowering stems.

Again, if not done already, there is still time to check the friability of the soil and aerate it to a depth of about 30cm in a rose bed or around rose bushes. One must not forget that the regular pruning, as well as cutting flowering stems with leaves during the growing season decreases root activity. It is therefore important that within the immediate rooting zone, it is easy for the bush to make hair roots and to absorb the required water and nutrition without having to go far to find it.
Creating cavities by breaking up clay lumps, loosening soil and retaining small stones allows air and water to penetrate easily. Digging in organic material such as compost, old manure, peanut shells, crushed pips or coarse milled bark chips, provides the roots with a prolonged feast and it will show in the growing and flowering throughout the season.
Digging in our controlled release VIGOLONGER fertiliser ensures that the plant receives controlled doses of the right nutrients for the next 6 – 8 months and makes fertilising more of a once off chore than a monthly one.
If you really want your roses to explode into flower, we recommend topping up with Vigorosa in mid-September, December and in March.
If it is found that water is standing or not draining away, the only options are digging a drain channel, if the bed is on a slight slope or uplifting the bushes and raising the bed with extra soil and compost and replanting it.
Hard soil and shallow watering resulting in a shallow root system
A bed where we added a thick layer of compost, peanut shells and a sprinkling of VIGOLONGER.
We then properly forked over the soil to a depth of 25cm making sure to mix in the soil enriching peanut shells, compost and fertiliser evenly. With such attention to the roots the roses are bound to perform superbly
standing or very slow draining water is deadly for a rose’s roots. It is best to raise such beds.
This inspection hole showed that over the years the soil became compressed and shallow with solid yellow clay just 20cm below.
Most of the roses in this bed were drowning
Most of the rose plants were uplifted, the whole bed was raised by 30cm, adding compost and organics, drain pipes were installed to take surplus water to the nearby drainage ditch and the bed is now perfect to start re-planting.
The soil around the bush has been lowered and the crown is drying out preventing new basals.
If one finds that the soil was eroded over the years and the crown is bare and has this dry look, cut out the dead wood retain one or two of last years stems and bring in composted soil to cover the crown. It will be a miraculous recovery by October.
cut out old and dead wood, retain 1 or 2 new stems and bring in extra composted soil to cover the crown
In the July issue of Talking Roses we also went into detail about scale insects and mealie bugs which have become an increasing problem in the past hot summer with not enough rain. In the meantime, we have run tests by spraying with various pesticides and we found that a combination/mixture of 100ml LUDWIG’S INSECT SPRAY with 10ml PLANT CARE in 10l water gave an excellent control within two weeks.

Roses of the Month: ‘Little Red Hedge’ and ‘Little Pink Hedge’
Whenever I look at these two varieties it seems like yesterday that they enchanted me and I came up with their appropriate names. They actually became favourites over the past 33 years. With their unique ability to sprout an endless supply of basal stems each bearing 30 to 50 small but nicely shaped blooms in the fashion of a Delphinium spike, they are indeed a perfect choice for a “little hedge” or useful as a border to large rose beds and shrubberies.
