Growing a flower in the open field

The Scarlet Rose Robusta has a subspecies of Pink Robusta. Its only difference is its larger buds of pale pink color. However, budding growers may find that the rules for caring for these two varieties may differ. In fact, there is no difference in the growing process.

Pink Robusta

Robusta does not have high requirements for soil quality and planting site. It can grow in both humid and arid climates. But still, for a more lush flowering, it is recommended to choose a sufficiently lit place with a little partial shade. It is advisable to choose a semi-loamy soil or create a substrate yourself from the following components (one part of each):

• turf;
• humus;
• peat;
• leafy land.

Planting seedlings is best done in the spring.

The rose is planted in the following sequence:

1. Before planting, the cutting is placed in a growth stimulant solution for several hours.
2. A hole is prepared with a depth of 60 cm and 70 cm in diameter.
3. A drainage layer is laid out at the bottom of the fossa.
4. The seedling is placed in the hole, the roots are covered with earth.
5. Mulching and watering are performed around the cutting.

Plant care

Despite the unpretentiousness of Robusta, for its proper growth it is necessary to follow the basic rules for caring for it. Watering the rose should be rare, but abundant. She needs 2 buckets of water about once every 10 days.

Watering

Watering should be carried out at the root within a radius of 20 cm from the bush. Do not allow the earthen coma to dry out, therefore, after 5 days, the soil must be loosened.

Top dressing and soil quality

Almost any soil is suitable for growing a rose, but it will feel better in a nutritious substrate. After planting next to the bush, weeding should be done to remove weeds.

Robusta is an unpretentious plant, but fertilization will always benefit her. For this, compost and humus are most often used. You need to feed the bush once at the beginning of summer, combining it with the mulching procedure.

Twice a year, the rose can be fertilized with liquid agents, for example, mullein infusion. One bush requires about 10 liters of solution.

Pruning and replanting

You need to cut the shrub in May, when the first young leaves appear. All frozen, dry and diseased areas are removed. Anti-aging pruning is performed no more than once every 5 years. To do this, at the beginning of autumn, it is necessary to remove all old shoots at the root.

If there is a need to transplant a rose, then this should be done in early spring or late autumn. If you have to perform the procedure at a different time, you will need to help the bush to take root in a new place.

Preparation for wintering

To prepare for winter, the bush is pruned, but not too short, as this can weaken the rose. Robusta also needs to provide shelter. It can be made from polyethylene or other non-woven material.

Blooming rose

The rose begins to bloom in May and throughout the summer, faded buds change to new ones. The most active vegetation occurs from mid-August to early September. If autumn is warm, then flowering can continue until October.

During flowering, the rose needs regular weeding and loosening. The dormant period for the Robusta rose begins in late autumn and ends in mid-spring.

Reasons for the lack of flowering

In some cases, Robusta may not bloom. This is due to the following reasons:

1. If the rose did not bloom on the first goal after planting, then there is nothing to worry about. In this case, the bush will root better in a new place.
2. With improper care, lack of dressing, or exposure to pests, flowering may not start. Problems should be rectified as soon as possible.
3. If the bush is cut too short, then it can throw all its energy into the growth of new branches and the flowering period will shift.

Flower propagation

Rose propagation is recommended from early to mid-summer. Robusta is grown by its own root method. For this, green cuttings are prepared in advance. They are cut into a length of 15-20 cm and placed in a growth stimulant solution. After that, their cuttings are planted in moistened nutrient soil. When the first leaves appear, the seedlings are transferred to a permanent place.

Diseases, pests and ways to control them

Despite its high immunity, Robusta can be exposed to some diseases and pests. Of the insects, aphids are the most dangerous for her. Regular insecticide treatment will help get rid of it.

Aphid

Powdery mildew and rust can cause serious damage to the flower if action is not taken promptly. Treatment with fungicides will help get rid of them.

In order to obtain the abundant and lush bloom of the Robusta rose, it needs to be properly cared for.In gratitude for this, she will become a real decoration of the garden plot.
