How to choose the right natural fertilizer for indoor plants can be a daunting task. There are hundreds of products available including fertilizers made from animal waste, seaweed, recycled rubber and recycled content. Some fertilizers contain micro-nutrients such as manganese, boron and iron. For best results it is best to purchase a high-quality natural fertilizer that contains copper, nitrogen, trace minerals and zinc. One that so many people inquire about is whether or not you can safely use coffee grounds on your indoor plants.
The use of coffee grounds as a soil additive has been used for decades. It has both cosmetic and practical benefits. The main advantage of using this as a soil additive is that it eliminates soil borne diseases such as nitrogen-phosphate imbalance and enhances root growth. When adding coffee to the topsoil of your flower bed, it acts as a natural diuretic and will draw excess moisture from the air in which the plant grows. This will reduce the need to water the plant, therefore reducing your watering costs.
Potassium is the most abundant mineral found in soil, however most plants require much more than the recommended amount. In order to keep your plants healthy you should add enough potassium to their root system. You will find that many commercial fertilizers will not provide all the nutrients including nitrogen that your plants need. For this reason you may want to consider a houseplant soil free of any other additives.
There are three major minerals that are found in plants, namely sodium, potassium and calcium. They all play important roles in plant growth. However they are all very volatile, with each having its own distinct time and place of use. If you are looking to maintain a thriving garden then you will be looking to add sufficient amounts of potassium and calcium to your houseplants. These two minerals are the chief determinants for the development of healthy plant structure and the regulation of internal pH levels.
The third mineral is magnesium. It is a very vital mineral that is found in plants as well as humans. The mineral plays an important role in plant respiration. As part of the nitrogen cycle, it is necessary for plants to absorb this mineral. Plants deficient in magnesium include eggshells and rock salt.
There are several types of fertilizers that are considered suitable, depending on the plant you have. However it is advisable to use one of the first two: potassium or calcium. Potassium is soluble in water, while calcium is insoluble. Potassium and calcium will work together if they are mixed with small amounts of both elements. If you are uncertain as to which to use, try a small amount of each until you find the right one. Most of the time, the plants you grow will respond to the combination.
Fertilizer that contains a large amount of nitrogen will need to be diluted before being used. You can dilute the fertilizer by adding some water and applying a bit of baking soda or lime to it. Another way of diluting is to add about five parts fertilizer to one cup of water. This way, you will have to dilute the fertilizer a bit more before applying it to the plants. It is not advisable to use dilute nitrogen fertilizer unless you know that the soil that you are growing is extremely poor in nitrogen.
There are a few other choices for organic fertilizers that can be beneficial to your indoor plants and flower garden. Thyme and black pepper both contain plant nutrients that are important for the health of your flowers and plants. Also, alfalfa, clover, and red millet are all great choices. Consider what you need and look for a product that combines those nutrients to ensure that your indoor plants and flowers thrive.
