Get Started: DIY Organic Fertilizers
The most important factor for healthy plant growth is healthy soil. As mentioned in Part 1, the key to building healthy soil is the regular addition of soil amendments like compost. If you are looking to replenish specific nutrients or to grow heavy feeders like tomatoes, you can make your own organic plant food at home. You need only apply small quantities when plants need it, rather than large amounts over the whole garden. Remember: LESS IS MORE when it comes to fertilizer. Read on for some low-cost or no-cost options for making your own gentle organic fertilizers at home.
Get Started: Why Fertilize?
All plants need light, water, and nutrients to thrive. Fertilizers can contribute nutrients to plant health, but a general rule of thumb is LESS is MORE. Heavy feeders like tomatoes often need additional nutrients that organic fertilizer can supplement; however, fertilizing is not the solution for most problems you encounter. Plants will only absorb the nutrients they require, and over-fertilizing can lead to wasted effort and a build-up of chemicals in your soil.
Get Started: Worm Composting (Vermicompost 101)
Also known as vermicomposting, this technique uses an ecosystem of earthworms and microbes to break down organic material into a natural fertilizer called worm castings. Gardeners consider this to be “black gold” because castings have very high levels of microbial activity that enriches soil and promotes water retention.
