The spring garden beckons with its awakening beauty, and impatient gardeners rush to decorate it with magnificent roses.
However, soil temperature plays a decisive role in the survival of these noble plants.
Experienced rose growers know special techniques that allow them to achieve lush flowering even with early planting.
Roses begin to actively develop their root system when the soil temperature is not lower than 10 degrees Celsius.
You can measure the temperature with a special soil thermometer by immersing it to a depth of 15-20 centimeters.
At lower rates, roots develop slowly, and the risk of rotting and fungal diseases increases.
Proper preparation of the planting site allows you to create a favorable microclimate for roses. The hole should be dug in advance, filling it with nutritious substrate.
Adding rotted manure or compost creates the effect of natural soil heating due to the decomposition of organic matter.
Frost-resistant varieties of Canadian and park selection are suitable for early spring planting.
Groundcover roses also demonstrate high resistance to low temperatures. Hybrid tea varieties require warmer conditions for successful rooting.
Gardeners use various methods to increase soil temperature.
Black film laid on the plot two weeks before planting accelerates the warming of the soil. Covering the future rose bed with transparent material creates a greenhouse effect.
The seedlings are planted in the first half of the day, when the soil is warmed up as much as possible. The root collar is placed 3-5 centimeters below the soil level.
After planting, the plants are covered with non-woven material to protect them from recurrent frosts.
Roses planted in cool soil require special attention for the first two weeks. Moderate watering with warm water stimulates root development.
Temporary shading protects immature plants from the bright spring sun. Timely loosening of the soil surface improves its aeration.
The introduction of root formation stimulants will help roses adapt to new conditions more quickly.
Regular spraying of leaves with clean water creates optimal air humidity.
When the first signs of growth appear, you can begin fertilizing with a weak solution of complex fertilizers.
