Organic Liquid Fertilizer

Rice water or boiled food water is the new organic liquid fertilizer for your garden plants! It isn’t only easy to make and apply but it’s also packed with loads of nutrients your plants will absolutely love. Whenever you whip up a hearty meal and boil (or steam) some vegetables, pasta, or rice, instead of pouring the used water down the drain, use it in your garden to water your plants! Water from boiled eggs will also make a great liquid fertilizer as it's rich in calcium. Practicing this will make a great alternative to creating a compost pile since it requires less space and time to produce!

Use Excess Cooking Liquids As Plant Fertilizer

Gardening is a practice that connects us deeply with nature - it's a labor of love. We nurture seedlings, working diligently to see them flourish. In this collective endeavor to help our gardens thrive, we continually search for new ideas, seeking out innovative ways to nurture our plants. However, sometimes the best resources are the ones already at our disposal. One such commonly overlooked resource is ordinary kitchen waste, specifically excess cooking liquids.

Utilizing Unused Cooking Liquids

The merits of composting your kitchen scraps are well known, but what about the leftover liquid lurking at the bottom of your vegetable steamer or rice cooker? That's right, those unassuming leftovers contain the perfect concoction of nutrients for your plants.

The Organic Liquid Fertilizer Miracle

When we steam or boil food, the water collects trace amounts of nutrients that could be beneficial if added to your garden's soil. From peas to potatoes, the water you cook your veggies in is full of beneficial minerals. This can easily become a handy organic liquid fertilizer.

The very water you were about to toss away, can now become a nourishing drink for your flora.

Recipes for Success

By incorporating simple changes into our kitchen routine, anyone can effortlessly create a homemade organic liquid fertilizer. Today, I am sharing my personal examples of how to utilize these nutrient-rich liquids.

Vegetable Broth

All those tasty vitamins and minerals vegetables are known for, from Vitamin K to iron, are abundant in vegetable broth, making it an excellent source of plant nutrition. Just make sure it's cooled before distributing.

Pasta Water

Similarly, the water you use to boil pasta or rice contains starches that plants love. It feeds their roots and helps healthy bacteria grow. And not forgetting, it aids in making the soil more fertile!

Coffee and Tea

For the caffeine addicts amongst us, you'll be glad to know that diluted leftover coffee (or tea) provides a fantastic nitrogen source for plants, improving leaf growth and overall health.

The Do’s and Don’ts

Now, a word to the wise, not all liquids are suitable for your garden. Citrus-based liquids and heavily salted broths are not recommended, as they can harm your plants. Also ensure to let any hot liquid cool before applying to avoid thermal shock.

Moreover, it's crucial to keep the use of such organic liquid fertilizers to a moderate level. Always observe your plants. If they show signs of suffering from over-fertilization, such as yellowing leaves, consider watering them with plain water for a period.

Remember, the goal is to supplement your plant's diet, not replace it completely. It's all about balance!
