What type of soil is suitable for roses
As one of the most beloved flowers by gardening enthusiasts, the growth state of roses is closely related to soil quality. High-quality cultivation substrates not only promote root development but also enhance the quality of the flowers. This article will delve into the golden rules of rose planting soil, helping you create an ideal growing environment for flowers.
Four ideal soil characteristics for roses
Permeability ensures root respiration
Rose roots require sufficient oxygen for respiration metabolism; it is recommended to use a mixed matrix containing 30% perlite. The finger insertion method can be used to test: insert your finger 5cm into the soil, and if there is moderate resistance and quick rebound, it indicates that the permeability meets the standard.
Drainage prevents waterlogging and root rot
The ideal drainage speed should maintain a penetration rate of 10-15cm of water per hour, which can be achieved through a 7:3 ratio of sandy loam to humus. Before planting, a 3cm thick layer of ceramsite can be placed at the bottom of the pot to form a natural drainage channel.
Continuous and stable nutrient supply
In addition to base fertilizer, it is recommended to add 200g of bone meal + 100g of slow-release fertilizer per cubic meter of soil. During the peak growing season, supplement with organic liquid fertilizer containing nitrogen, phosphorus, and potassium every month, maintaining an EC value between 1.2-1.8mS/cm.
Precise control of pH value
The optimal pH range is 5.5-6.5, which can be tested monthly with pH test paper. If the soil is too alkaline, add sulfur powder (50g per square meter); if too acidic, mix in lime powder (100g per square meter), and the adjustment process should be completed over 2-3 weeks.
