Newsletters: talking roses July ’16

‘When you have only two dollars left in the world, buy a loaf of bread with one, and a rose with the other.’

Chinese Proverb

In the Rose Garden with Ludwig

On my return from attending the Regional World Rose Convention in China I was happy to find that our roses were still flowering quite well considering it was supposed to be winter. Even after the few cold days, and the rain a week ago, we still have a lot of colour to show and super big blooms to admire.

After digging over the beds, picking out lots and lots of the beetle larvae (as shown in the May newsletter) and drenching the soil, our newly planted trial roses recovered and are sprouting happily, even with some nice new blooms.

At this time of year, one’s fingers itch to start pruning, but with the relatively warm winter temperatures it is important to hold back. In years gone by our co-workers made small fires early in the morning to warm their hands after shifting and loading the iced-up dormant container rose plants. Now, it seems that such frosty mornings have shifted to late July / August. This image is a mock-up. It was not really cold enough for a little fire.

I noticed in our trials how a massive pressure of black spot spores from close by black spot sensitive variety is able to infect the leaves of a black spot resistant eco-chic variety. It shows that as long as we do treasure older non-resistant varieties, preventative spraying during the “black spot weather” is important.

My impressions from the Rose Convention in China

I need just one word to describe my experience of roses in China – Superlative!

On arrival at Beijing Airport I noticed roses planted en masse, but the traffic was so heavy I could not cross the road to take a closer look. And it didn’t stop; roses planted down highways, in parks, at the convention centre, in metre high displays – whenever we thought there were no more roses to see, we discovered some more. Here are just some images to show what I mean…

Pruning demo & 20% discount Star Roses – KZN

I will be giving a talk on how and when best to prune your roses in KZN at Star Roses on Saturday 25 and Sunday 26 June at 10:30. We will be offering a special -20% discount on all rose plants and we will also be running specials for the day on selected fertilisers, composts and sprays.

Please see below under News from our Rose Centres for the dates in July when I will be hosting pruning demo’s at our other branches. Here too the -20% discount will apply on the demo weekends.

Step by Step Rose Care for July

October is Rose month but July is pruning month and it seems as if rose growing revolves around these two very important months.

Although I claim that roses prune themselves and do not need us to do so, it is like mowing the lawn – it looks neat afterwards and there is the expectation of beautiful blooms just two months later. With warmish weather it is best to delay pruning to the second half of July in order to avoid the early sprouting of new leaves which are then subjected to cool, moist conditions that could bring on fungus diseases. Obviously, conditions vary around the country. Pruning early or late July has no influence on the flowering time in October, which is determined by the weather pattern in September.

How to Prune

It is important to accept that you cannot prune a rose wrongly.

A 2m high rose bush that was cut back or pruned to 75cm last year can receive the same treatment now.

By inspecting and observing how each rose has grown over the past season you will see where the best stems developed and that gives one a lead – that is, to follow the strongest sap flow which is evident in good strong healthy stems and retain them while removing any twiggy older stems that have already been neglected by the bush.

Deciding how severely to prune back a rose is, to a degree, is personal. The principle is that every remaining stem or stub needs to sprout. Leaving lots of stems means lots of medium to short stemmed blooms, while fewer “cutting points” means fewer, but longer stemmed blooms.

We all know that roses are sun loving plants, meaning they need lots of direct light onto the leaves to encourage photosynthesis which produces food that is transported to the roots. Since new stems and leaves always start sprouting at the highest points, the stems that sprout lower down and in the centre of the bush will soon be in the shade and unable to produce flowering stems. Therefore, cut out all the stems that are growing towards the inside centre. If left, they will soon dry out – not a problem just a nuisance.

A few tips

We have short video clips on how easy it is to prune roses. Please click here to access the videos…

Here are a few images to show how easy pruning really is:

AFTERCARE

It is advisable to spray after pruning, especially to eradicate scale insects that invaded so many roses last summer because of the heat and insufficient water flow within the plants. If there is a very obvious visible scale population it is best to brush them off and then spray. The best, effective spray at this stage is the oil-based spray Ludwig’s Insect Spray (100ml mixed in 10 litres water, double the strength of normal application).

Spraying the same onto the cuts suffices as a seal. No need to seal the cuts with a tree sealer or Steriseal.

With the soil likely to be compacted by this is the time of the year, it is necessary to provide the roots with a better airy environment. Add a layer of compost, peanut shells, crushed apricot pips or coarse pine bark or even a bit of manure if available (all these materials are contained in Ludwig’s Planting Mix) and dig this in 25cm deep making sure it is well mixed with the soil so that the soil feels spongy.

Drench very well with water and keep on watering once a week until end August. No problem if it is more often due to automatic irrigation systems.

You might consider applying our new fertiliser VIGOLONGER right after pruning.

This multicoated, controlled released fertiliser needs to be mixed into the soil down to root level. It cannot cause burning but will provide a source of nutrients for the whole season. When the brown granules become moist and as temperatiures rise the fertiliser within the granule dissolve and is sucked through the polymer coat by osmosis into to the soil and is then easily absorbed by the roots. Really magnificent stuff!

The nutrients released ensure a nicely even growth, compared to a sudden burst when applying Vigorosa or any other fertiliser.

The rose however still welcomes a boost of Vigorosa on occasions, such as mid-September for additional growth and again in December and March.

Roses of the Month: Rhona Lya

Rhona Lya

This rose variety really stands out at the moment. The bushes are full of healthy leaves and they carry many blooms. This is a true sign of its natural vigour!

The deep cognac colour of the bud flows to hues of deep cream and honey gold in the opening bloom. They have a good vase life and best of all exude a distinct sweet, honey fragrance.
