The New Zealand delphinium differs from its counterparts in high stems and large inflorescences. It is considered one of the most beloved plant species by gardeners. It rises impressively on the site and is a stem, covered almost entirely with flowers. A cluster of inflorescences can reach 70 cm, and the diameter of flowers can be 9-10 cm.

Depending on the variety, flowers can be double, semi-double and simple.
The classic look of the flower has five petals. But such delphiniums are usually not grown. There is a spur on the top petal of the flower. Thanks to him, the plant is sometimes called spur. The petals of the flower, after full disclosure, have a greenish strip in the middle. This is due to the fact that the bud is green when unblown. Having blossomed, it changes color, but not completely - a barely noticeable greenish strip remains.

The plant can be found in the wild in Asia, America, Europe, Africa. It adapts perfectly to virtually any conditions. However, it requires light soil and relative warmth. Delphinium is actively used in landscape design, without it, winter gardens, greenhouses and personal plots are already unthinkable.

Any plant variety requires certain conditions cultivation... They are not complicated, but it is necessary to provide them. Growing conditions will always depend on the region. In the northern regions, the delphinium is planted later, in the southern regions, on the contrary. But there are general rules and conditions for growing a plant.
Delphinium loves sunny places with light soil. The plant is quite unpretentious, but it will not grow in damp soil and a dark place. The flowers will be small and pale. Delphinium does not tolerate acidic soil well. If you plan to plant a plant in such a soil, slaked lime should be added to the soil.
For a lurter, you need to carefully prepare the ground where it will grow. If this is done, the plant will grow without problems, it will not need to be endlessly fed and monitored for the appearance of diseases.
The soil is prepared as follows:
- In the fall, they dig up the earth and add a complex fertilizer.
- After that, peat, garden soil and well-rotted humus are added. The ratio of the components is one part from each.
- In the spring, the earth is dug up again and superphosphate, ammonium sulfate and potassium salt are added to it according to the instructions on the packages.
- If the land is damp and moisture accumulates on the site, it is necessary to add river sand to the bottom of the hole under the delphinium. The sand is covered with a substrate of peat, garden soil and humus.
So prepare the soil under landing you only need one time. Further, the plant will grow and do not require additional care in the form of frequent top dressing and fertilization. Try to choose a place for it so that the sun's rays fall on the plant in the morning, and the light should be diffused during the day.
The place should be well ventilated, but protected from northerly winds.
Aeration will prevent slugs from appearing. Soil preparation is especially important in the case of poor land on the site. It is difficult to grow a large and lush delphinium bush in poor soil. The flowers will be small. Compliance with these simple rules will allow you to grow luxurious bushes with large flowers.It is important to know information about proper cultivation. seedlings from seeds. After all, this is how they begin to breed delphinium.
Seeds burgers are very small, about 2 mm long. It is quite difficult to plant them one at a time, so they are sown in a bunch. Fresh seeds are preferable. If it is not yet time to plant them, the raw materials are placed in the refrigerator. You need to store the harvested seeds in the cold. This will ensure friendly plant shoots. If the seeds are dry, then the chances of growing at least one full-fledged bush are minimized.
Before planting delphinium seeds, disinfect them in a solution of potassium permanganate.
Then rinse, dry and place in the refrigerator for a while (two to three days). Then you can start sowing. The soil for seedlings prepared from equal parts of peat, humus and garden soil. Charcoal can be added for additional disinfection. The prepared soil should be slightly damp.
Features of planting seeds:
- The seeds are placed at a depth of about 2 mm and covered with earth.
- Water the seedlings carefully so as not to wash the seeds. You can just spray warm, settled water.
- The container is covered with glass or foil until germination.
- Optimum temperature germination 10°-15°.
- When the first two or three leaves appear, the seedlings are dived and placed in a place where the air temperature is 20 °.
So the seedlings are grown to the formation of an already strong bush with a height of about 10 cm, depending on the variety.
Plant seedlings necessary in a warm ground, when the threat of frost is no longer there. Choose a permanent location according to the growing conditions. The bushes are deepened into pits about 40 cm in diameter, the distance between the pits will be 50 cm or more, depending on the type of plant. The optimal composition of the soil will be: peat (one part), garden soil (one part) and humus (one part).
If the land has not been prepared according to the growing conditions, it is necessary to add a complex mineral fertilizer.
As the seedlings grow in open ground, fertilizers should be applied, but this measure is provided only in the case of unprepared land. Delphinium, especially in the growth phase, does not tolerate drought. It is necessary to monitor young seedlings and water them in a timely manner. If frost suddenly came, it's okay. Delphinium tolerates them well. You can cover them with non-woven material as a preventive measure.
Having planted the seedlings correctly, the gardener can no longer worry about his pet and wait for a luxurious flowering... It is worth noting that annuals are planted with seeds in the fall so that they bloom in July. But this condition does not apply to the New Zealand delphinium, since it is a perennial.
The plant does not require special care:
- It is important to monitor the moisture content of the soil at first. Do not overfill the splurge. He does not like dampness and drought.
- You should also cut off faded inflorescences in a timely manner.
- If humus and complex fertilizer were not added to the soil during planting, the delphinium needs to be fed during the growth period. Top dressing is carried out every two weeks. In the fall, it is stopped so that the plant gains strength for wintering.
- There is one interesting nuance in plant care. Always remember that cutting off dead flowers will provoke re-flowering. This is undesirable if the region where the delphinium is grown has short summers and harsh autumns. The plant simply does not have time to gain strength for the winter.
- In the fall spend pruning plant stems up to 20-30 cm from the ground. It is advisable to cover the cavities of the stems with clay or garden putty. This is to prevent moisture from getting inside to the root outlet. The plant can rot.
Otherwise, the delphinium quite simply goes to winter. It doesn't need to be covered.Some gardeners, especially in the northern regions, cover it with spruce branches. It's enough.
The most frequent "guests" of the delphinium are slugs, delphinium fly, aphids, powdery mildew and black spot.
Pests: types and control:
- Aphids and flies are most commonly reported due to hot and dry summers. To combat these pests resort to the use of insecticides. They can also be used to treat the plant as a prophylaxis.
- Slugs appear due to dampness of the soil. This usually occurs during rainy and cold summers. Therefore, it is important to plant the plant in a well-ventilated area. You can fight slugs with chlorine. Its smell scares them away.
Plant diseases appear more often in the second half of summer. Powdery mildew can be removed with the help of Fundazol. But here the main thing is to notice the fungus that has appeared in time. Otherwise, you can lose your favorite plant. If black or ring-like spots appear, the leaves are best trimmed. It is almost impossible to get rid of these diseases. Therefore, it is more expedient to immediately remove the affected parts of the plant.
To avoid the appearance of pests or diseases, treat delphinium with insecticides and fungicides as a preventive measure.
It is quite easy to grow a New Zealand delphinium. You just need to follow the basic rules and conditions of growing. In this case, the marvelous plant will always delight you with beautiful and impressive flowers. Always consider the region where the delphinium will "live".
