IN THE ROSE GARDEN WITH LUDWIG
I have just returned from Ludwig’s Star Rose centre in Assegai/Hillcrest in KZN and the incredible blooms are still vividly impressed on my mind. They were planted in September and have grown enormously; enough to be mistaken for mature established bushes. They were not only in full bloom, but still carried huge, unspoilt blooms and clusters in very intense colours. The reason for this – they were planted in deeply loosened soil, mixed by a skid steer excavator with our planting mix and lots of peanut shells. Each plant is watered by a mini sprinkler every 2nd day for an hour. However, one must not discount the local weather. With few rain showers and relative low humidity there was no fungus disease so little spraying was required. The present conditions of cool nights and clear cloudless days are what the roses like most. Having traveled far and wide last month to look at roses in France, I can say that I did not come across such a concentration of hundreds of varieties, properly grouped, which makes comparing and selection so very easy. These images say it all.

Giving a pruning demo in such luscious garden was not easy. One would think that such roses do not need pruning, but the bushes would grow too high, the blooms would get smaller and stems on the inside of the bushes would not receive any light and dry out. In short, without pruning, they would look messy in September. My advice to the visitors and our staff was to stop watering for about two weeks. With the withdrawal of water, the lower leaves on the bushes will quickly turn yellow and drop off and the roses will at least be semi-dormant by end July and ready to be pruned.
‘Passion of St Peters’ is ready to be pruned ‘Guehlila’ with golden leaves and ripe hips is an attraction too
We almost had the same situation here in Pretoria. The roses took a set back after a few frosty nights and then just kept on flowering. Cutting down on the watering started the dormancy process.
‘Forever Busy’ in bloom These yellow leaves are normal for winter
I hear it often said that now in winter we can take a rest. Not so. The start for saleable rose plants for the next season is in full swing. Budding material has to be cut off the plants before pruning, prepared and stored in a cool room. And then the pruning starts which keeps us busy for this month.

ROSE CARE FOR JULY
July is the month to prune roses for most regions in South Africa. With the roses growing and flowering into winter, as a result of our watering, fertilising and spraying, pruning in the second half of this month is gentler on the roses. However, if you want to get it done right now it will have no adverse consequences. The same applies if it has to be carried out in early August. It is only in regions which experience frost in Early September that the pruning is delayed to end August.
Pruning basically entails a cutting back, as stated in the Encyclopaedia, it is the removal of superfluous wood.
If you click here you find all the stages of pruning of the various rose types described and illustrated.

For those who would like a quick summary, here it is:
Why roses like pruning
Pruning gives roses a helping hand by cutting out dead and superfluous wood.
In spring, when the sap rises from the roots, it finds less resistance in last season’s basal stems compared to the older grey and often gnarled branches. These old woody stems are superfluous and should be cut out. Removing criss-crossing stems, weak twiggy growth and opening up the centre of the bush also gives the rose room to develop strong new shoots.
Which roses to prune
Pruning is most beneficial for hybrid tea, floribunda and the bush types of the English and nostalgia roses as well as standard roses. Miniature and groundcover roses just need to be shaped and tidied up with hedge clippers.
Different degrees of pruning
Light pruning is best for bushes that are spaced far apart or are growing in compacted soil in a shady position or with tallish companion plants surrounding them.
Cut the rose bush back to between 80 cm to 1 metre leaving several side stems on the main branches. Remove all the leaves. This forces the development of green leaves that give power to the roots.
Medium Pruning is for gardeners who feel that their roses need more pruning than light pruning but that severe pruning is too extreme.
Cut the rose bush back to between 80cm to 1m. Inspect the remaining growth to see which main stems (this season’s growth) or branches (two years or older growth) should remain. Select three or four suitable stems and reduce the length by a further 10 to 20cm. Remove or shorten remaining side stems and forks.
Severe Pruning is suitable for roses planted very close together, or grew very tall last season. This is also the best method for floribunda roses, except ‘Iceberg’.
Cut the rose back as you would for light and moderate pruning but shorten the remaining stems to 40cm. Remove or shorten remaining side stems and forks.
But a word of warning: only prune the bushes severely if you intend enriching the soil after pruning and if there is a regular programme of watering and fertilising the roses during the growing season.
Roses that only receive sporadic attention, should not be severely pruned because they will not rejuvenate satisfactorily afterwards. Rather opt for light pruning.
Pruning and espaliering of climbing roses, which includes our PanarosaTM range, entails training them up on vertical supports, such as pillars, walls, fences and pergolas. It is easier and more effective if the climbing canes are bowered or secured in a horizontal or fanned position. Here are some images that show how it can look.
Bowering climbing canes on a frame a long climbing shoot is trained horizontal is sprouting from every eye
The vertically stretched wiring makes tying climbers easy
Stakes, riet or bamboo make an attractive frame for espaliering a climber
Pull off all the leaves. Dig over the beds to the depth of 20cm incorporating last season’s mulch and additional quantities of organics, home made compost if possible and even some composted or decomposed pig or chicken manure. Vigorosa can also be mixed in.
Water very well after digging over the beds and keep on watering at least weekly until September when the watering cycle should be increased.
ROSE OF THE MONTH ‘Tourmaline’
Shapely, pointed buds unfold into open, cup shaped blooms, displaying a most interesting colour combination of basic white with an edge of pink which flows softly down the petals & fades into white. The bushes grow vigorously & produce long, sturdy stems & lush, glossy foliage.
NEWS FROM OUR ROSE CENTERS

The hail netting over the roses seems to have kept the light frost out and a lot of the roses are in bud and coming into bloom and the pruning will be kept back to late July unless heavy frost puts an end to the flowering season.
