Preparing seedlings and planting area
For planting to be successful, you need to take care of high-quality planting material. When choosing Skyrocket juniper seedlings, you should consider their size.Planting material with a height of no more than 1 m takes root best. Adaptation to new conditions is faster, and the survival rate is high.
If you managed to get seedlings that are 2-3 years old, then they should have a closed root system and should be grown only in containers. Living and healthy plants have flexible trunks and branches.
When purchasing plants, you should only contact reliable suppliers or nurseries. Many online stores also sell Skyrocket rockweed seedlings. Private owners often offer certain varieties of juniper for a lot of money. But in this case, without knowing the description and characteristics of the plant, you can run into a forgery.
Seedlings with an open root system are placed in water. Plants in containers are watered generously.
For planting, select a well-lit area with no drafts. Despite the fact that rock juniper is unpretentious, you need to prepare a seat. Delete weeds with a well-developed root system, dig up the planting site.
Under natural conditions, the plant is found on rocks, so be sure to add broken red brick, pebbles or crushed stone of large fractions. The soil is mixed with peat and humus to provide nutrition in the first 1-3 years. Only in this case the plant will quickly take root. But it will begin to grow only after the development of the root system.
Landing rules
It is best to plant plants with an open root system in the spring.With container juniper Skyrocket (the seedling is shown in the photo below) everything is simpler; it can be used at any time (spring, summer, autumn). The main thing is that there is no heat.
Stages of planting juniper:
- The hole is dug in advance, 2-3 weeks before planting. It should be spacious so that the roots are located freely in it. The depth of the planting site depends on the composition of the soil. If the soil is clayey or chernozem, dig a hole at least 1 m deep. In sandy and sandy loam soils, 80 cm is sufficient.
- Drainage is laid at the bottom of the hole, and a fertile layer is placed on top.
- When transplanting, the Skyrocket juniper seedling is removed from the container, being careful not to damage the root system. Juniper is planted together with a lump of earth.
- There is no need to deepen the root collar; it should rise 10 cm above the surface level.
- The juniper seedling is sprinkled with nutritious soil and compacted well to release air pockets.
- After this, the tree is watered abundantly.
- Experienced gardeners advise installing a support in the center to loosely fix the trunk and give the juniper stability.
- On the second day, you will have to add soil to the tree trunk circle, since after watering it will settle a little and the roots may be exposed. And this is undesirable.
- To preserve moisture, the surface around the Skyrocket rock juniper (in the Moscow region, among others) is mulched with peat, wood chips, and dry leaves. The layer must be at least 5 cm.
Watering and fertilizing
Rock juniper Skyrocket, according to descriptions and reviews, does not require abundant and regular watering. It will only need additional moisture if there has been no precipitation for a long time. Dry soil can cause the needles to turn yellow and the tree to lose its external beauty.

The plant needs feeding throughout its life, as it abundantly grows green mass every year. For nutrition, feeds intended for conifers are used.
Mulching and loosening
Since juniper does not tolerate drought well, to retain moisture, the soil in the tree trunk circle must be loosened from time to time and weeds removed. These events can be avoided if you mulch the tree trunk circle. This operation is carried out immediately after planting, then mulch is added as needed.
Trimming Juniper Skyrocket
As stated in the description, Skyrocket rock juniper needs pruning. It must be carried out annually. Young flexible branches grow 15-20 cm. If they are not shortened in a timely manner, they move away from the main trunk under the weight of the green mass. As a result, the juniper becomes unkempt, as people say, shaggy.
That is why branches are cut, but only in early spring, before the movement of sap begins. Otherwise, the plants may die.
Preparing the Skyrocket rock juniper for winter

- In late autumn, before the onset of stable frosts, the trees are wrapped in non-woven material and tied with rope, like a Christmas tree.
- To preserve the root system in the tree trunk circle, increase the height of the mulch to 20 cm.
Reproduction
The Skyrocket variety is not propagated by seeds, since the method is ineffective.
It is best to focus on the vegetative method:
- Cuttings are cut 10 cm long. Harvesting is planned for the end of April - mid-May.
- The planting material is kept in a root formation stimulator for 24 hours.
- Then they are placed in a mixture of sand and peat (in equal proportions) for 45 days.
