Newsletters: Happy, Rosy New Year! talking roses in January ’17

The more one gardens, the more one learns; And the more one learns, the more one realizes how little one knows.

Vita Sackville-West

In the Rose Garden with Ludwig

Two weeks ago I had to send our rose information to be published in March to the gardening magazines. Very much thumb sucking as to what the weather will be like in the meantime.

As I am finalising this issue on 8 January, it is pouring with rain! On and off for three days and our dams are filling up.

The weather was mostly kind to us and the roses during December, resulting in an amazing rose month. There was drizzle and cloudy weather with enough blue sky to quickly dry up the leaves and keep the soil moist. Not much cutting back and pruning was done in November because we didn’t know what to expect from the weather, with the effect that many hybrid tea’s performed like Floribundas. Lots of short flowering shoots on one main stem.

New Zealand

‘New Zealand’ – a performer with a wonderful, strong fragrance.

Addictive Lure

‘Addictive Lure’ – not just the scent that is addictive!

Cordwalles one stem note the many buds to open soon

‘Cordwalles Centenary Rose’ – the many buds sprouted from one single stem will open soon.

Lesotho Prince

‘Lesotho Prince’ – the colour and perfect shape are always charming.

Mushe Kirsh

‘Mushe Kirsh’ is an amazing Antico Moderno rose!

Alec's Red

‘Alec’s Red’ – a mainstay favourite with an unbeatable fragrance!

We were also careful when fertilising, not knowing if our dams would start filling, but with the nice weather, we applied Vigorosa around the younger plants. Within a week, the light green leaves, which are a clear indication of nitrogen deficiency, turned deep green and the leaves doubled in size. Such finely tuned decisions are what farmers and rose growers need to take all the time. Fertilising without sufficient water might cause burning. Undernourished plants will not produce, and in the case of roses, it also means that such plants become susceptible to black spot infection.

The beetle invasion we experienced earlier on has petered out after one good spraying with Cyper, which is available from our rose centres for garden use. Usually they come back two, three weeks later. Ha, again, a day after the first good rains on 2nd January the CMR beetles arrived and started to chew on the David Austin English Roses.

Just around New Year is the time to trim or groom the red varieties that produce good cut roses for Valentine’s Day. Mister Lincoln, Cora Marie, Belle Rouge, Five Roses, and Boksburg Fantasia are our main varieties. For you at home just one glorious bowl of Papa Meilland should suffice. Oh, but the children need to take some to school too. Here is how it is done – scroll down to our green summer pruning and grooming instructions further down.

This stem was cut back on 28 Dec, photo taken on 9 January. It will produce two pickable stems.

I was walking with my grandsons through Southdown’s, a gated community in Irene. All neat and clean and the gardens well kept. Lots and lots of Standard ‘Iceberg’, as is the case everywhere.

However, what amazed me was that quite a few of these standards where green, sheared like a mop head with maybe the odd bloom in-between.

It was of course the rootstock that had sprouted on the stem underneath the grafting. Instead of being pulled off, cut or ripped off the main stem, the light green thornless stems were kept and cut at the top by the garden maintenance company.

Especially at the younger stage, sprouting of the rootstock from the main stem on standards does happen. Simply cutting them off doesn’t help, as they will just sprout again. One needs to rip off the shoot, pulling them downwards so that the dormant eyes are removed as well.

Green Summer Pruning

I am hosting demonstrations on how to correctly green summer prune your roses at this time of the year, at our branches. Please see dates and times further down. I look forward to seeing you there!

For those of you who are unable to attend, we have uploaded a short but informative video on how it is done…

Step by Step Rose Care for January

Your weather and availability of water determines what could or should be done to your rose bushes and climbers at this point, halfway into the flowering season.

For the dry regions, the advice is still the same. Retain the foliage; no cutting back or even dead heading.

Obviously no fertilising either if there is not enough water. There is very little chance of fungus diseases and spraying for them is not necessary. Red spider mites could become a problem and in that case, it is best to spray with a MILBEKNOCK and INSECT SPRAY cocktail to keep them under control.

Mulching to keep the water in the soil cool is important. Use whatever material is available i.e. dry lawn clippings, leaves, pips, pebbles, peanut shells, pine bark chunks, paving stones or pine cones. Any material that will allow the water to get through and not suck it up, will do.

Don’t use compost, because that will encourage any root growth upwards. No digging at this stage either. If the soil appears hard and does not allow water to penetrate easily, it is best to just spike the soil with a digging fork to a depth of 20cm.

And again – GREY WATER IS BETTER THAN NO WATER. Our video on how to implement grey water harvesting can be viewed here…

Roses growing in pots cannot survive without daily watering, unless one has introduced water holding material such as coco peat or swell gel.

Roses that have suffered from the drought and are now getting drenching rain are best left alone for two to three weeks.

They will soon sprout and make new leaves like mad. Thereafter it is important to spray and avoid black spot infection. There should likely be lots of nutrition dissolving, which will become available to the roots, so there is no need to fertilise. More on what to do in this case will feature in our February newsletter.

For those who are back to normal gardening with good rains and no water restrictions, these are the points to consider for reaping beautiful roses over the next few months.

Black Spot in centre of bush

Without green summer pruning black spot easily infects the centre of the bush.

These images give a good idea of how to apply green summer pruning:

If the spent blooms on this ‘Fairest Cape’ were just left on the bush, it would take forever for new shoots and buds to appear.

3 days after dead heading, the sprouting is already evident.

After summer green pruning has been applied, the remaining stems will bear quality shoots and large blooms.

This Floribunda ‘Forever Busy’ that is full of all stages of blooms and buds does not have to be green summer pruned or dead headed.

If you pick cut roses regularly, the bushes do not need to be green summer pruned. The picking automatically encourages quality new sprouting.

To learn all the tips and tricks, you are welcome to attend one of our Summer Rose Care Workshop as detailed below.

Attendance is free and there is no need to book. You are welcome to bring samples of any rose problems or blooms for identification.

Roses of the Month Giver of Hope

Giver of Hope

This ‘Giver of Hope’ is an elegant, exhibition shaped hybrid tea that will easily reach shoulder height. It bears good stems for cutting blooms for the vase. The blooms are very large and perfectly simmetrical. They are white, with a light yellow delicately yet distinctly visible in its centre. The blooms bear a slight note of fragrance.
