Spirea Cantonese Lanciata is a plant that requires a combination of several factors at once, such as a suitable climate, temperature, and the presence of shelter for the winter, for the successful cultivation of which.
Description of spirei cantonskoy Lanciata
This decorative low – reaches a height of one and a half meters – the shrub belongs to the group of spring-flowering spirea. The main feature of spring-flowering plants is that their flowers begin to form only in the spring of the second year of the shoot. As with all species belonging to this group, they are characterized by the presence of many flowering shoots. The branches are thin, arched.
From the usual Cantonese spirea, the Lanziata spirea differs in the shape and size of the inflorescences – it is characterized by double white flowers, reaching a diameter of 5–7 cm.
Planting and care
In order to grow the Cantonese Lanziata spirea, you need to know the basic details of planting and caring for it.
Preparation of planting material and site
The choice of a suitable landing site largely depends on the climate. Since Lanciata is a heat-loving plant, it is worth choosing a warm place in advance or taking care of shelter for the winter.
In general, Cantonese spirea practically does not differ from other plants of its kind – it is photophilous, prefers well-lit space, but if necessary, tolerates penumbra well. It suits neutral soil with a low level of acidity, which takes moisture well. For example, sandy or light loamy.
Seedlings for transplantation can be sold both with an open root system, and together with a part of the soil, with closed roots. Despite the fact that in the second case it is difficult to determine the state of the plant, such spireas take root much better.
If we are talking about a seedling with open roots, then when choosing it is necessary to check their condition. The roots of a healthy plant are flexible, do not break when bent, and do not look dry. If the root system is poorly developed, you can cut off its lower third before planting.
Rules of landing
Spring-flowering spireas are planted in open ground in autumn, approximately in late September – early October, before the foliage is completely crumbled. However, this only applies to seedlings with open rhizomes, and plants in containers can be transplanted at any time. In a rainy region, it is better to plant spirea in late spring or early summer, after the earth has warmed up.
For planting, it is better to use a soil mixture: combine 2 parts of turf and one part of humus and sand. Sand can be replaced with another part of the humus.
The planting hole should be about a third larger than the root system of the bush. The minimum distance for young seedlings is approximately 60 cm between bushes, but the recommended distance between plants is 1 m.
Planted like this:
- First, dig a hole. The minimum depth is about half a meter, the diameter is 60 cm.
- If necessary, make a drainage ditch.
- Leave a hole for 2-3 days before planting.
- Prepare the soil mixture.
- Pour the mixture, set the seedling, straighten the roots.
- They fall asleep with the rest of the mixture, trampling the soil around the bush a little. The stem should start from the ground, and not sink into it.
- Plentifully water the spirea.
- Mulch the soil as desired.
Watering and top dressing
Spiraea is recommended to be watered abundantly, but infrequently, 5-6 times per season is enough. The amount of water should be significant, at least 15-20 liters.
In dry and hot weather, the frequency of watering can be increased.
Fertilizers are applied during planting – then the soil is fertilized with wood ash (500 g per 1 square meter) and superphosphate (300 g per 1 square meter). Nitrogen and phosphorus fertilizers feed the soil in the spring, and potash fertilizers are used every 2–3 years, shortly before sheltering for the winter.
Trimming
Since Spirea Lanciata propagates by shoots, regular pruning becomes a necessity for it. It is of two types:
- annual pruning of the ends of the shoots;
- stem removal.
Annual pruning is carried out in the spring, its purpose is to remove the frozen ends of the stems.
Whole shoots are removed after they stop blooming. As a rule, this happens once every 7-10 years.
And also the spirea is cut to give it the desired shape – for this, the branches are shortened. Such pruning can harm a very young plant, so it is better to refrain from the procedure in the first 2-3 years.
There is anti-aging pruning: the branches of old plants, that is, those that are more than 14–15 years old, are cut off, leaving 5–10 cm.
The annual pruning of Lanziata is done in the spring, but the shape of the spirea is given closer to autumn, when flowering is over.
Preparation for winter
Preparation for winter depends on the climatic conditions of the region. In the southern regions, if the temperature does not drop below zero, special preparation is not needed – the spirea will not freeze. In other cases, the bush must be covered.
Small seedlings cover in any case. To do this, they are covered with any breathable coating, after which they are fixed. You can use both specialized materials and natural remedies.
Be sure to cover the root part of the spirea – cover it with a layer of mulch, and then cover it with foliage or lay branches.
If the winter is snowy, then the upper part of the spirea is not touched – the snow cover will serve as a natural shelter. They cover the bush in the event that there is little snow. To do this, the branches are collected, bent to the ground, fixed and covered with foliage or special breathable material.
Reproduction
Spiraea Cantonese Lanciata can reproduce in several ways:
- cuttings;
- seeds;
- division of the bush.
In general, the cultivation technology is standard, but each method has its own characteristics.
When propagating by cuttings, it is important to remember that:
- for the initial planting of the cuttings, a soil mixture of peat and river sand in a ratio of 1: 1 is well suited;
- within one season, you can take the cutting twice: when pruning in spring and summer, after flowering;
- mineral and organic fertilizers in the soil for growing spirea from cuttings are not suitable;
- spirea is planted in open ground in a permanent place only a year after grafting, in the fall.
When dividing a bush, it is important to remember that:
- the sprout formed during division is transplanted either in early spring or in autumn, closer to mid-September.
When propagating the Cantonese Lanziata spirea with seeds, it is worth remembering that:
- seeds can be either bought or collected and prepared independently;
- spirea blooms when grown from seeds not immediately, but for 3-4 years;
- seeds are not immediately planted in open ground, before that they are kept in containers using specially prepared soil;
- after germination, the sprouts are treated with fungicidal preparations to prevent a possible disease;
- spirea is planted in open ground only for the second season.
For growing Lanciata from seeds, a soil mixture of turf and peat in a ratio of 1: 1 is suitable.
Diseases and pests
Although Cantonese spirea is resistant to pests, it can also become diseased.
The most dangerous for her, especially at an early age, are fungal infections, for example, the occurrence of gray mold. Since spirea does not have any specific features, standard fungicides are suitable to combat infection.
Of the pests Lanziate are dangerous:
- spire aphid;
- leaflet;
- spider mite etc.
To combat them, various acaricides and insecticides are used.
Conclusion
Since the Cantonese spirea Lanziata is a purely decorative plant and at the same time extremely thermophilic, it is easiest and most convenient to grow it exclusively in a warm climate. Otherwise, there is a possibility that in inappropriate conditions the spirea will die. However, with the exception of thermophilicity, this bush is surprisingly unpretentious and disease resistant in care. So if during the first few years the Cantonese spirea did not die, you can be sure that Lanziata will delight the gardener with its beautiful view for the next decade.
