Plant Food Basics
Just like people, plants need to eat in order to thrive. While many high quality bagged soils, such as Miracle-Gro® All Purpose Garden Soil and Miracle-Gro® Potting Mix, contain plenty of food to give plants a good start, many plants (especially heavy-feeding plants like tomatoes and melons) need more as the season wears on. See, as plants grow and continue to feed, the nutrition in the soil eventually becomes depleted and needs to be replaced. The best way to do that is to feed your plants with plant food, also known as fertilizer.
Plant food delivers three main nutrients to plants:
- El nitrógeno (N) ayuda a avivar el crecimiento
- El fósforo (P) fomenta el desarrollo de las raíces, aumenta las flores y ayuda a las plantas a tener un buen inicio
- El potasio (K) es esencial para la salud en general de la planta, la ayuda a combatir las enfermedades y soportar condiciones de crecimiento estresantes (como la sequía y el calor)
These three key nutrients appear somewhere on every plant food package as a series of numbers, such as the 12-4-8 found on Miracle-Gro® Shake 'N Feed All Purpose Plant Food. The first number, 12, refers to the percentage, by weight, of nitrogen (N) in the plant food. The second number, 4, refers to the percentage of phosphorus (P), and the last number, 8, refers to the percentage of potassium (K).
Plants also benefit from other nutrients, such as calcium and magnesium, which are included in many plant foods. If you look on the back of any fertilizer package, youll see a list of all the nutrients it contains.
Plant food typically comes in three different forms: continuous release, liquid, and water soluble powders. Continuous release plant food, like Miracle-Gro® Shake 'N Feed All Purpose Plant Food usually comes in granular form, and the nutrients are released slowly over time. Mix this type of fertilizer directly into the soil surrounding the plant. Details on when and how much to apply are spelled out clearly on the label.
With liquid and water soluble fertilizers, the feeding happens when you water. Miracle-Gro® Water Soluble All Purpose Plant Food, for example, can either be added to the water in a watering can, or delivered through your garden hose. Miracle-Gro® Liquafeed® Universal Feeder attaches directly to the spigot, while Miracle-Gro® Garden Feeder attaches to your hose. These kinds of plant food needs to be applied more often than continuous release plant food, but the nutrients also reach plants far more quickly.
No matter what kind of plant food you choose, be sure to follow the directions on the label for the best results. Do that and your plants will never go hungry!
