Growing healthy nasturtiums can be easy and rewarding with the right fertilizer. Organic fertilizers not only nourish your plants but also improve soil health. Here are some simple DIY recipes to boost your nasturtium growth naturally.
Homemade Fish Emulsion Fertilizer
This nutrient-rich fertilizer is made from fish waste and provides essential nitrogen, phosphorus, and potassium. It encourages lush foliage and vibrant blooms.
- 1 part fish waste (or fish scraps)
- 5 parts water
- A few drops of liquid soap (optional, for better mixing)
Mix the fish waste with water and let it sit for 2-3 days, stirring occasionally. Strain before applying to your nasturtiums every 2-3 weeks.
Banana Peel Compost Tea
Banana peels are rich in potassium and magnesium, which promote flowering. Making a compost tea extracts these nutrients for quick absorption by plants.
- 2 banana peels
- 1 gallon water
- Optional: a handful of compost
Chop the banana peels and steep them in water for 48 hours. Strain and dilute the tea before watering your nasturtiums weekly.
Seaweed Extract Solution
Seaweed is a natural source of trace minerals and growth hormones. It helps strengthen plants and improve overall health.
- 1 cup dried seaweed (kelp or other seaweed)
- 1 gallon water
- Optional: a few drops of liquid soap
Soak the seaweed in water for 1-2 days, then blend or mash. Strain and use the liquid as a foliar spray or soil drench every 2 weeks.
Final Tips for Healthy Nasturtiums
Besides organic fertilizing, ensure your nasturtiums receive adequate sunlight, water, and well-drained soil. Regularly remove dead leaves and monitor for pests. With proper care and natural fertilizers, your nasturtiums will flourish with vibrant blooms and healthy foliage.
