Quick Fixes

Step 1

Apply foliar spray of potassium sulfate or potassium nitrate solution (follow product dilution rates) directly to leaves for fastest absorption

Step 2

Water soil thoroughly before applying soil drench to avoid root burn

Step 3

Apply highly soluble potassium fertilizer (0-0-50 or similar high-K formula) as soil drench around root zone

Step 4

Reapply foliar spray every 7-10 days until symptoms diminish

Step 5

Monitor new growth for signs of recovery within 1-2 weeks

🌿

Organic Treatment

Work wood ash sparingly into topsoil (approximately 1 cup per 10 square feet, avoid if soil pH is already high)

Step 3

Apply seaweed extract or kelp meal according to package directions for immediate nutrient boost

Step 4

Spread granite dust or rock phosphate for long-term slow-release potassium

Step 5

Maintain 2-3 inch mulch layer to prevent nutrient leaching

🌱 How to Care for Common Houseleek to Prevent Potassium Deficiency?

💧 How to Water

Water sparingly, allowing soil to dry completely between waterings. In summer, water once every 2-3 weeks. Reduce to monthly or less in winter. Overwatering is the main killer - when in doubt, do not water.

☀️ Lighting

Requires full sun for best coloration and compact growth. At least 6 hours of direct sunlight daily. Can tolerate partial shade but may become leggy and lose vibrant colors. Provide afternoon shade in extremely hot climates.

🪴 Ideal Soil

Requires excellent drainage - use sandy, gravelly, or gritty soil. A cactus/succulent mix works well. Tolerates poor, rocky soils. Never use moisture-retentive potting mixes.
