forget-me-nots;
petunias;
verbena.

Step-by-step instruction

A place

Rosa Graham Thomas loves diffused bright light. It grows well in semi-shady areas, but flowering will not be so plentiful, the flowers will have a pale yellow color. For full growth, the variety needs daylight hours of up to 5-6 hours a day.

The bushes should be well ventilated, stagnant air in dense plantings provokes the appearance of harmful pests and diseases.

The soil

The soil should be:

fertile;
acidified;
light
drained.

For growing in tubs, it is recommended to use a soil mixture:

Garden land - 2 hours
Sand - 1 hour
Sod land - 1 h.
Sheet land - 1 h.
Humus - 1 hour
Dried clay - 1 hour.
Drainage.

Drainage layer, up to 4 - 6 cm, the composition of the drainage includes coarse sand, clay fragments, pebbles.

Regular loosening (shallow) of the soil, removal of weeds is required.

Landing

In the southern climate, you can sow seeds in the fall, in a shallow trench, so that the seeds go through natural stratification.
On top of the trench is sprinkled with a layer of a mixture of sand and soil.
Sowing is sprinkled with leaves, covered with coniferous spruce branches.
Cover material is fixed on top. Holes are left at the base so that the sowing does not ripen and rot.
In spring, the shelter is removed, the soil is cleaned from leaves, seedlings begin to break through.

Seedlings grown in this way are more resistant to disease, quickly adapt and take root in a new place.

You can germinate the seeds in the greenhouse.

Pre-soaked seeds in any growth hormone for 2 hours. The procedure is carried out in early autumn.

Rules for growing crops in a greenhouse:

Seeds are laid out on a moist soil mixture without deepening.
Sowing is sprinkled with a layer of sand, up to 0.5 cm.
The soil is moistened, seeds are pressed slightly.
Sowing is covered with a film.
Germination air temperature - 20 - 22 ° C.
The light is bright, moderate watering, through a spray bottle.
Airing the greenhouse daily, for 10 - 15 minutes. in a day.
After 3 weeks, the greenhouse is transferred to the basement or installed in a cool room, the air temperature is 7 - 8 ° C.
After 2 to 3 months, the seedlings are taken out to a bright place.

To accustom seedlings to light and fresh air should be gradual.

Temperature

The optimum temperature of the rose content in the tub or in the flowerpot is up to 22 - 25 ° C.

In the flowerbed, when the temperature rises to 28 - 30 ° C, the rose will need additional hydration - spraying the bushes in the morning.

The variety tolerates a decrease in air temperature in autumn., up to 12 - 15 ° C. The bush continues to bloom until September - early October.

Watering

Regular watering, up to 5 liters of water is spent on young bushes, for adult bushes the volume of water increases. Water for irrigation should be used only clean, settled, room temperature.

In the fall, watering is reduced. The amount of precipitation is sufficient to moisten the air and soil.

After rain and spraying, the branches must be shaken off so that the water does not linger in dense inflorescences.

Top dressing

Before planting, a bucket of compost mixed with 300 g of ash is added to the soil.

In early spring, nitrogen fertilizers are used for shoot growth. for fast growth and restoration of stems after winter.

In summer, the soil is fertilized with mineral complexes of potash and phosphorus fertilizers.

Florists recommend the use of special fertilizers:

"Hera";
Agricola
"Blank sheet", etc.

Mineral fertilizers should be alternated with organic top dressing:

chicken droppings;
cow dung;
tincture of weed.

Pruning

Spring pruning (for the formation of a beautiful bush and cleansing after winter):
