What Do Plants Crave?

what do plants crave

Indoor plants and garden plants crave appropriate sunlight, soil, and water. In addition to that, plants also need nutrients, which they tend to get from the soil.

The burst of nutrients through the growing season can be your plant care secret weapon to having great-looking plants.

Gives Plants Essential Nutrients They Need

Consider giving your plants a few rounds of fertilizer to promote healthy green plants during the growing season.

Especially if the houseplant’s soil is becoming stale, pouring some rice water into the ground to get to the plant roots can spark new growth.


Rice Water Is Cheaper to Use than Other Fertilizers


One of the benefits of using rice water compared to store-bought organic fertilizers is that it will be cheaper. Buying a box of rice is relatively inexpensive, and all you need is to make a quarter-cup or so of rice to gather some rice water. By mixing regular tap water and rice water, you can create an excellent liquid diet for plants.


One tip is to put the rice water into a spray bottle as you water plants because it will conserve more water, which means you can use it more often. Otherwise, you might dump too much rice water on plants, so you will need to get more.

Acts as a Pesticide

Using rice water on plant soil can act as a pesticide against unwanted pests. Some common bugs that rice water can detract from latching onto your plant include gnats, beetles, aphids, etc.


Beneficial Bacteria in the Roots of Plants

Rice water encourages bacteria known as lactobacilli to form in the plant soil. This healthy bacteria promotes healthy root growth in plants, which aids with overall plant growth.


Is White or Brown Rice Liquid Better for Plants?

Is White or Brown Rice Liquid Better for Plants

Using white rice or brown rice liquid on plants won’t make much difference. They both have different nutrients, so it depends on what you seek. For example, manganese, an essential nutrient in growth, has more in brown rice than white rice. However, white rice tends to have fewer grams of sugar than brown rice, so it becomes an equal trade-off on what to use.

Can You Add Rice Water to a Compost Pile for Fertilizer

While there are many benefits to using rice water on plants directly, another advantage of using this leftover water is adding it to your compost pile. If you are composting in your home and use that material as fertilizer for your garden, add the excess rice water to it. The rice water can keep the rest of the items in the compost pile moist and help break down things like banana peels, potato skins, coffee grounds, and tea bags.


One tip is not to put uncooked rice in the compost pile. Uncooked rice becomes harder to break down in your compost pile, so you are better off cooking the rice and putting any extra that you can’t eat into the compost pile than putting uncooked rice there.


Are There Any Downsides to Using Rice Water on Plants?

Are There Any Downsides to Using Rice Water on Plants

One thing to remember about using rice water on plants is to ensure that it becomes room temperature before dumping it directly on a plant. Just like how plants don’t like a burst of cold liquid, plants also don’t want hot and steamy liquid. After cooking and letting that water stay out for a bit, you can use it directly on plants.


Another thing to remember about using rice water on plants is that this is a fertilizer, so you don’t want to overdo it to start. Like using any liquid fertilizer, you want to introduce your houseplants to this new diet gradually. Consider using a 50% mix of rice water and regular tap water to give your plants a taste of these additional nutrients before giving them 100% rice water.


Conclusion: Is Rice Water Good for Plants?

In summary, the question “is rice water good for plants” is a resounding yes. To start, it is a cheap DIY fertilizer option, has loads of nutrients, and can also detract bugs from latching onto the plant. You can also add the rice water to your compost pile for future fertilization, so you don’t have to use it immediately.


While there are many benefits to using rice water on plants, plant owners should remember two things. First, only use rice water on plants when it reaches room temperature. You don’t want to shock the plant with hot temperatures if they are unfamiliar with it. Second, you want to introduce your plants to this new nutrient-rich diet gradually, so consider giving a 50% mix of water and rice water to avoid overloading your plant with too many nutrients.
