History of occurrence
This species was bred in Finland at the end of the 20th century on the basis of Smirnov's rhododendron. The variety got its name in honor of the name of the mother of its creator.
This is one of the most successful experiments in rhododendron breeding, because the Helliki variety differs from other winter-hardy species in its excellent frost resistance and special brightness of flowers.
Distinguishing Features
Helliki's rhododendron has a number of differences. Grows slowly, prefers slightly shaded places. Does not feel well in direct sunlight and may get burns.
When planting, choose a place so that the plant is protected from drafts. The root of the plant is flat and located close to the surface, so it can be easily damaged. The variety withstands frosts down to -36 degrees.
Growing
Helliki's rhododendron requires certain conditions for successful growth and flowering.
Choice of location and soil
Seedlings should be planted in soil with a high level of acidity (Ph from 4.5 to 6.5). Choose a place for planting in such a way that the plants are protected from direct sunlight and drafts.
Rhododendron of this species does not tolerate high humidity. In order for the plant to please with an abundance of flowers for the next year, you need to remove those inflorescences that have already faded in time.
Selection of seedlings and planting dates
A young plant intended for planting should be strong and he althy, with no visible damage. Plant rhododendron in open ground in autumn or spring.
Planting
When planting, it is important to place drainage consisting of pebbles and sand on the bottom of the finished hole. The earth is poured to the level of the root neck. Planting a plant should not be too deep. After planting, moisten the soil well. Mulching is done with coniferous needles, peat. The layer of mulch should be 5 cm.
Temperature
When forming buds, the most suitable temperature is +12 - 13 degrees. In the future, the plant will be able to tolerate a sharp drop in temperature.
Irrigation
Although the plant does not like excessive moisture, it is impossible to allow the soil to dry out. In summer, watering should be moderate. Water the rhododendron with plain or acidified water. To obtain it, a little sphagnum peat is placed in a bucket of water for a day.
Feeding and loosening
You need to fertilize not only seedlings, but also adult plants. Feed them a small amount of these substances:
- Calcium.
- Ammonium.
- Potassium sulphate.
When feeding young plants, the amount of fertilizer used should be less than for adults. In mid-July, the feeding of all bushes is reduced by 2 times. Compost or humus is used only for adult bushes, mixing them in equal proportions with peat.
Loosening the soil under these plants is highly undesirable because the root is superficial and easily damaged. It is also better to remove weeds manually. Mulching will be a good preventive measure to protect the roots of seedlings from problems.
Cutting
Carry out such a procedure at the very beginning of spring.Pruning is done not only to cleanse the bush from withered shoots, but also for decorative purposes - this is how the crown is formed. To do this, cut off the upper part of the tallest shoots. To avoid infection, the pruning site must be immediately treated with garden pitch.
Transfer
The plant tolerates the transplant procedure normally. Adaptation to a new place is fast. You can not transplant the plant during its flowering period, as well as 2 weeks after that.
Wintering
Shelter for the winter period, this variety of rhododendron does not require. Before the onset of cold weather, the plant is well watered and covered with mulch.
Flowering
During the flowering period, the area looks especially bright. To make it abundant, you need to know a few rules.
When and how it happens
Bright and incredibly beautiful flowers will appear in the first decade of June. Helliki's rhododendron blooms for a short time - only 3 weeks.
Containment conditions
This species takes root well and lives for a long time even in areas with a temperate and cool climate. For 10 years, the bush grows to a height of up to 1 meter.
If it doesn't bloom
Sometimes the flowering of the bush is delayed. This is due to insufficient acidity of the soil. In this case, it is necessary to increase it, as well as to feed the plant with additional minerals. For full and timely flowering, diseased, as well as sluggish branches and shoots must be removed from the plant.
Diseases and pests
Unfortunately, rhododendrons are susceptible to pests and diseases:
- Septoria spotting.
- Phytophthora rot.
- Root rot.
- Tracheomycosis.
- Washing out.
Often the occurrence of these pathologies is associated with excessive soil moisture and low acidity.
Spider mite
The tick is very small, so almost invisible. You can judge the defeat by the presence of cobwebs on the back of the rhododendron leaves.
To get rid of these parasites, the plant is treated with fungicides such as:
- tiram;
- karbofos;
- agravertine.
Snails and slugs
These mollusks are dangerous enemies of Helliki's rhododendron. It is they who most often affect the bushes and can destroy the plant in the shortest possible time. They need to be manually removed from the bushes. Molluscicide treatment also helps.
Weevil
The insect feeds on all parts of the plant. Diazonin solution will help to cope with such a problem.
For greater effectiveness of preparations, their solutions should treat not only the plant itself, but also the soil in the near-stem circle.
How to propagate
Most often, the rhododendron is propagated using cuttings. Do it like this:
- cut a strong shoot 8-10 cm long;
- plant it in a prepared substrate consisting of a mixture of peat and sand in equal proportions;
- cover with glass or film. The greenhouse must be periodically ventilated, providing the young plant with air access. The seedling will take root within 3 months.
- next spring, mature plants are planted in open ground
Saplings should winter in a dry, cool room.
Prevention of various problems
In early spring, the bushes are sprayed with Bordeaux liquid. If the plant is affected by rot, then you need to immediately cut off the diseased branches. In the event that the bush is completely affected, it must be urgently removed from the site.
Such a substance as iron chelate will help to avoid the problem of yellowing leaves in rhododendron.
