Want to give your plants a boost and see faster, healthier growth without using synthetic fertilizers? This DIY growth spray is the perfect solution.
Made with natural, kitchen-friendly ingredients, this spray delivers key nutrients and plant hormones directly through the leaves, helping plants absorb what they need — fast. Whether you’re growing vegetables, herbs, or flowers, this simple spray accelerates growth and strengthens overall plant health.
Let’s explore how to make it, how it works, and how to use it for the best results.
Why Use a Growth Spray?
Plants absorb nutrients through both their roots and leaves. A foliar spray:
- Delivers nutrients quickly to stressed or slow-growing plants
- Encourages faster leaf and root development
- Helps plants recover from transplant shock or nutrient deficiency
- Supports flowering and fruiting in high-demand stages
It’s perfect for periods of rapid growth, seasonal transitions, or underperforming plants.
