Barberry Rose Glow is a bright accent in the flower garden, combining well with many plants. Among the numerous varieties of Thunberg barberry, this one is distinguished by its special decorativeness. The amazing pink color of the foliage from a distance gives the impression of lush flowering.
Description of barberry Rose Glow
There are more than 500 wild species of barberry in nature, and there are also many cultivated varieties created by breeders on their basis. Among them, most of all are Thunberg barberries; this large group includes Rose Glow. He is taller than many of its representatives. Good care will allow it to reach a height of 1.5 m in 10 years. The spherical crown is even wider - up to 2 m. Each year the branches grow by 15 cm.
Adult ovoid leaves of this barberry variety are purple in color, slightly diluted with dark pink spots. But the main beauty is given to Rose Glow by young growths; they, like the leaves, are colored deep pink. This alone would be enough to plant a plant in the garden. But nature became generous and painted them with spots and stripes of white-pink and bronze-red.In bright sun they appear silvery.
The shrub is also good in bloom. At the very end of May or in the first ten days of June, each shoot is decorated with yellow flowers with reddish outer petals. They can hang from the axils of the leaves one at a time or 2-3 at a time. When the foliage, which turned orange by autumn, falls off, the bush will be hung with bright corals of oblong, rather large, up to 1 cm, berries for a long time. Like most ornamental barberries, they are inedible, although not poisonous. At this time, long spines are clearly visible, sitting one at a time in the nodes of lignified gray shoots.
A description of Thunberg's barberry Rose Glow would be incomplete without mentioning its other characteristics:
- frost resistance;
- unpretentiousness;
- undemanding to growing conditions;
- drought resistance;
- resistance to diseases and pests;
- ability to withstand haircuts and poor environmental conditions of a big city.
You can list the advantages of Rose Glow barberry for a long time, but the photo will say more about it:
Barberry Rose Glow in landscape design
Rose Glow barberry will make a wonderful tapeworm, a very beautiful shrub in the company of its fellow barberries, but with less bright foliage they will be an excellent background for it. Of the perennial shrubs, the most suitable spirea as a companion is birch-leaved or Grefsheim: a waterfall of white flowers on a pink background looks very elegant.
You can plant paniculata hydrangea nearby, for example, Vanilla Frize or Limelight. Initially white and then pinkish inflorescences will create an excellent color ensemble with the rich color of Rose Glow foliage. It looks great next to conifers: junipers, thujas, Konica spruce or low firs. Rose Glow cuts well and is suitable for a natural hedge or neat border.
Rose Glow barberry bushes will look good at the edge of plantings of tall trees, but you cannot combine it with poplars, acacias or elderberries. Due to the phytoncides secreted by these plants, it will be depressed and may completely die. You shouldn't plant summer trees next to it either. The superficial root system of barberry is easily damaged when digging.
Planting and caring for barberry Thunberg Rose Glow
It is not difficult to carry them out due to the unpretentiousness of the bush, but there are still some peculiarities. Rose Glow has certain preferences when choosing a planting site and nuances in care. If you follow them, the decorativeness of the plant will always be at its best.
Preparing seedlings and planting area
Like all variegated barberries, Rose Glow can demonstrate the peak of its decorative potential only with sufficient lighting. It will grow well in partial shade, but the color of the leaves will fade. There are other requirements for Rose Glow’s habitat and soil preparation:
- it grows best on loam or sandy loam, on which nothing has been planted before;
- soil fertility should be at an average level; there is no need to actively fertilize the bush;
- the soil reaction may differ slightly, but not too much, from neutral in one direction or another;
- drainage is a prerequisite for the successful growth of Rose Glow;
- Despite the drought resistance of barberry, the area should be sufficiently moist when planting.
In addition to good lighting, Rose Glow also needs protection from strong winds.Where it will grow, moisture should not stagnate in the spring or during prolonged rains. Groundwater should be low.
If you buy a barberry seedling with a closed root system, it does not need any special preparation. You may need to soak the pot in water for 20 minutes if the soil is very dry.
Barberry Rose Glow plants with bare roots will require more careful preparation:
- carry out an audit of the root system, cutting out all dried and damaged roots;
- soak them in water to which any root formation stimulator has been added (diluted according to instructions) for 3 hours.
Landing rules
First you need to decide for what purpose this variety of barberry is planted:
- as a tapeworm, it will need a lot of space so that as Rose Glow grows it does not become crowded; tall plants growing close together can block the view;
- when planting in a group of several bushes, you need to leave at least 1.5 m between them;
- when constructing a hedge for its density, the distance between plants is 50 cm.
Both autumn and spring planting of Rose Glow barberry is possible. An indispensable condition is that the plant is in the resting phase. Why do experienced gardeners insist on this so much? Frail barberry roots will not be able to adequately nourish an already awakened plant. At best, it will hurt for a long time, at worst, it will die.
The only exception is container seedlings. Their intact root system immediately begins to grow. This barberry survives well throughout the growing season.
Landing algorithm:
- In Rose Glow, the roots grow in width and not in depth, so it does not need a large hole for planting: for 2-3 year old seedlings - 25 cm deep, for older ones - up to 50 cm, the main guideline is the size of the root system, it is in the pit should be spacious.
- If you plan to build a hedge from Rose Glow barberry, it is easier to dig a ditch; its size is: width - 40 cm, depth is the same, and the length is determined by the need, taking into account that the seedlings will be located in it every 50 cm.
- Drainage is required when planting barberry plants of any age.
- Prepare a planting mixture to fill the hole by mixing garden soil, humus and sand in equal quantities.
- A glass of ash and 100 g of phosphorus fertilizers are added to each hole.
- Pour in a bucket of water.
- Straighten the roots of the barberry without shaking off the soil from them.
- Cover with planting mixture, compacting it, and water again.
In all others, the root collar should be level with the soil or a couple of cm higher.
The final touch is mulching with humus or peat. They should not be neglected - moisture in the soil will be better retained, and Rose Glow will begin to grow more quickly.
Watering and fertilizing
Regular, once a week, moisture is required only for recently planted plants. Already rooted barberries need watering only in case of severe drought or high air temperatures. Cold water will not work; it needs to be heated in the sun.
Barberry is fed from the second year of life:
- For the speedy regrowth of young shoots in the spring, they give fertilizers rich in nitrogen - dissolve Art.a spoonful of urea in a bucket of water and poured under an adult bush; for children, divide this amount in half or into 3 parts, depending on age;
- On the eve of flowering, you will need a mineral fertilizer containing the entire set of nutrients, including microelements in the amount of tbsp. a spoon on a bush, they are scattered, mixed with the soil by shallow loosening and watered;
- at the beginning of autumn, apply 15 g of superphosphate and 10 g of dry potassium sulfate under each adult Rose Glow barberry bush and seal it with loosening.
Barberry is fed with organic matter once every 3 years. Slurry is suitable - 1.5 liters per bucket of water or 1 liter of bird droppings infusion for the same amount of water. Watering with clean water after this is mandatory.
Trimming
This is a rather traumatic operation, given the thorns.
The types of pruning depend on the role that Rose Glow plays in the garden:
- for tapeworm, it is enough to form a spherical crown by cutting off excess branches once a season in the spring;
- trimming the barberry border is carried out more often - in early June and the first ten days of August, using a special long ruler or wooden plank to obtain the same level of the plant crown;Important! The next year after planting the Rose Glow barberry as a hedge, the shoots are cut by at least half for better branching.
- A natural hedge requires only sanitary pruning to remove dry, frozen, broken or abnormally growing branches.
If the bush is very bare at the bottom, rejuvenating pruning to the stump will be required. Barberry will quickly recover and will be decorative again.
Preparing for winter
Thunberg's barberry comes from warmer climes - Japan and China. Its varieties, including Rose Glow, have higher frost resistance. But young plants still need shelter in the first few seasons. There is no need to be very zealous with it - just wrap the barberry bush in one layer of non-woven material 60 microns thick. Excessive cover of barberry will create another problem - damping off of the shoots. It wouldn’t hurt to insulate its root system by adding a bucket of humus under the bush.
Reproduction
It makes no sense to propagate varietal barberries, including Rose Glow, by seeds - the seedlings will not replicate their parents. The only way out is vegetative propagation: by dividing the bush and cuttings. The latter method is especially good if you need a large number of barberry plants to create a hedge.
Rules for cuttings
- the best survival rate is for green barberry cuttings cut in June;
- for cuttings, choose this year's growth, the middle part of the shoot with 4 leaves and one internode, about 10 cm long and half a centimeter thick;
- The bottom is cut obliquely, the top is cut horizontally;
- Having removed the lower leaves and cut off the top 2 leaves in half, the barberry cutting is dipped with the lower part in root formation stimulator powder;
- It is better to root cuttings in a mini-greenhouse, the soil is light, a mixture of sand and peat with the addition of vermicult;
- there should be a layer of sand on top, 4 cm thick, and planting is carried out in it with a slope to the south and a depth of 1 cm;
- feeding area for each cutting – 5x7 cm;
- Soil humidity is constant and air humidity is 85%, which is achieved by frequent spraying.
The first, and sometimes the second, wintering is at the rooting site; young Rose Glow barberries are moved into the garden after 1-2 years.
By the time of division, the Rose Glow barberry bush should already be 3 years old. The best time for the procedure is spring, before the kidneys wake up. The dug up barberry plants are divided into parts with sharp pruning shears, each of which should contain roots and stems. The cut site is treated with charcoal powder and the cuttings are planted.
Diseases and pests
Most often, Rose Glow is affected by diseases of a fungal nature, which are especially rampant in the summer with heavy rains.
- Powdery mildew – a clearly visible coating on the leaves of barberry is white. Removing the affected parts of the plant and dusting with colloidal sulfur will help.
Advice! If the weather is damp for a long time, it is better not to wait for the disease to develop, but to carry out preventive spraying of barberry bushes with a copper-containing fungicide. - Rust - orange spots on the leaves. The control measures are the same.
- spotting – spots on leaves that soon dry out. Treating barberry with a copper oxychloride solution will help.
- Drying of stems and necrosis of bark. Both diseases have a similar nature - fungal, manifestation - drying out of large trunks or branches and control measures: cut off the damaged parts, capturing up to 15 cm of healthy tissue and treat the barberry plants with a solution of copper sulfate.
- Bacteriosis – dark spots that can appear on any part of the plant. You will have to remove the diseased tissue, and if the lesion is at the base of the trunk, then the entire bush.
The most common pests of Rose Glow are the caterpillar larvae of the barberry sawfly and the flower moth. To destroy them, use a 2% Karbofos solution. A soap solution is effective against barberry aphids.Bioinsecticides, for example Fitoverm, are also suitable.
Conclusion
Barberry Rose Glow will decorate your garden plot, giving it new, fresh colors without requiring special care.
