Instructions<\/strong><\/h2>\n
    \n
  • Shake the container thoroughly before use to ensure uniform nutrient distribution.<\/li>\n
  • Dilute the fertilizer according to plant type and growth stage. A general recommendation is 5 to 10 ml of fertilizer per 1 liter of water for routine feeding.<\/li>\n
  • For indoor plants, apply the diluted solution directly to the soil around the base of the plant. Avoid overwatering.<\/li>\n
  • For outdoor plants and garden beds, apply evenly to moist soil to ensure proper nutrient absorption.<\/li>\n
  • For foliar feeding, use a lower concentration and spray directly onto leaves during cooler parts of the day. Avoid spraying during intense sunlight.<\/li>\n
  • Feed plants every 1 to 2 weeks during the active growing season. Reduce frequency during dormant or slow-growth periods.<\/li>\n
  • Do not exceed recommended dosage to prevent nutrient burn or salt accumulation in the soil.<\/li>\n
  • For young seedlings or delicate plants, use a diluted concentration at half strength.<\/li>\n
  • Water plants lightly before applying fertilizer if the soil is very dry to prevent root stress.<\/li>\n
  • Clean measuring tools after use and close the container tightly.<\/li>\n
  • Store the fertilizer in a cool, dry place away from direct sunlight and extreme temperatures.<\/li>\n<\/ul>\n
