The Cultivation Method and Precautions of Marjoram
As an herb with both ornamental and purifying functions, marjoram has become a new favorite in home gardening in recent years. Its silver-green leaves and light purple inflorescences complement each other beautifully, but to cultivate healthy plants, one must master these key care points.
I. Three Key Elements of Environmental Control
Soil Matrix Mixing
A neutral sandy loam soil is the ideal choice, recommended to mix leaf mold, river sand, and perlite in a ratio of 3:2:1. When potting, lay 3cm of ceramsite at the bottom to enhance drainage and prevent waterlogging and root rot.
Light and Temperature Control
In spring and autumn, it should receive 6 hours of scattered light daily, and in summer, a shade net is needed to filter strong sunlight. In winter, maintain a temperature above 15°C for overwintering, and it is recommended to keep it indoors in northern regions.
Nutrition Supply Plan
Using sheep manure mixed with bone meal as a base fertilizer is more effective, and during the growing period, apply diluted seaweed fertilizer every 45 days. Applying additional phosphorus and potassium fertilizers during the budding stage can increase the number of flowers.
II. Daily Management Details
Seeding and Transplanting Techniques
Soak the seeds in warm water for 8 hours before spring sowing, and the sowing depth should not exceed 0.5cm. Transplant the seedlings with 4 pairs of true leaves, and the new pot diameter should be 5cm larger than the original pot.

Wrap the pot with straw before the cold wave arrives and use a transparent plastic bag at night to keep warm. Gradually warm up frozen plants and avoid direct exposure to high temperatures.
IV. Advantages of Home Cultivation
