Potash Fertilizer (Sulphate of Potash – SOP) is a high-quality, chloride-free source of potassium and sulfur that helps plants produce more flowers, healthier fruit, and stronger roots. It supports better water use, disease resistance, and nutrient uptake, especially important in Pakistan’s hot, dry, or clay-heavy soils.

Unlike other potash types, SOP is gentle and safe — ideal for fruiting and flowering plants like chillies, tomatoes, citrus, mango, roses, and more.

🌿 Key Benefits:

• Boosts Flowers & Fruit: Promotes bud formation, fruit size, and bloom quality

• Builds Stress Resistance: Helps plants fight pests, heat, and overwatering

• Improves Water Use: Reduces wilting and improves drought resilience

• Safe for Edibles: No chlorine — won’t damage roots or alter fruit taste

• Ideal for Local Crops: Works great for kitchen gardens, fruit trees, and rooftop pots

📝 How to Use

Soil Drench (Roots):

• Mix 1 teaspoon (5g) in 1 liter of water
  
• Apply around the base of plants, avoiding stems/leaves
  
• Repeat every 2–3 weeks during flowering or fruiting stage

Foliar Spray (Leaves):

• Mix ½ tsp in 2 liters of water
  
• Spray both sides of leaves in early morning or evening
  
• Avoid applying in hot sun or in rainy weather

FAQs – Potash Fertilizer SOP

What’s special about SOP vs other potash?
SOP has no chloride, making it safer for vegetables, fruit trees, and sensitive roots. It won’t affect fruit flavor like MOP (Muriate of Potash) sometimes can.

Is it safe for edible plants?
Yes — just wash produce before harvest. Stop spraying 7 days before picking.

Can I use it with compost or NPK?
Yes — Potash works well with compost, vermicompost, NPK, and seaweed extract. Don’t mix directly with calcium products.

💡 Tip:

Apply SOP when flowers start forming — not after fruit has already grown. It helps set more fruit, prevents flower drop, and builds stronger stems that can handle heavy yields.
