When it comes to organic fertilizers for gardening in containers, you have two basic options: granular or liquid. Let’s talk about each of them in detail.
Complete Granular fertilizers for gardening in containers
There are dozens of different brands of complete granular fertilizer mixtures. Most of these products combine different plant ingredients, fertilizers, animals and minerals, and depending on the brand, they can have an N-P-K ratio of 4-5-4 or 3-3-3 or something similar. What makes them” complete ” is that they contain a combination of ingredients that provides a certain amount of the three macronutrients (nitrogen, phosphorus and potassium), in addition to many trace elements, vitamins and others. All these products have different formulations and compositions, so be sure to choose according to the plants that you grow in your garden in containers. Some complete granular fertilizer mixtures are even suitable for certain crops, such as tomatoes or flowers or onions, and are labeled as such.
To achieve the best results, add granulated fertilizer to your containers according to the instructions on the label. Many gardeners find that they achieve the best results by fertilizing their containers with granular fertilizer two or three times during the growing season.
With granular products it is possible to have too many good things. Even natural fertilizers can be easily overexerted, which leads to various problems, including nutrient deficiency, pH imbalance and/or “burning” of fertilizers (yes, even some natural fertilizers are capable of this). To avoid these problems, do not overdo it by applying too much too often. Again, be sure to follow all the instructions on the label.
Liquid Organic Fertilizers for garden in container
Liquid fertilizers are absorbed into the plants through their roots and leaves. In general, the nutrients provided to the plants via a liquid solution are more easily and quickly available for use by the plants. Like all fertilizers, water-soluble fertilizers provide plants with some of the nutrients needed to increase yields and improve growth and vitality, but not all liquid fertilizers are created equal.
Although water-soluble fertilizers on a chemical basis certainly provide plants with the macronutrients indicated on the label, these products are made from salts that can harm the beneficial organisms in the soil. Instead of salt-based chemical fertilizers, look for organic or natural fluids that can reduce the risk of burning fertilizer and provide a more balanced “diet” for your plants. In addition to the three macronutrients, most natural liquid fertilizers for containers also contain dozens of trace elements, vitamins, amino acids and plant hormones, each of which plays an important role in the health and vitality of a plant.
here are mTany types of liquid fertilizer on the shelf of your local garden center, or in some matter you can even make your own. Here are some of the most popular types of natural liquid fertilizers.
The above products are useful on their own, but they are also very valuable when combined with other ingredients. Natural liquid fertilizer combinations mix these products with ingredients such as liquid bone meal, blood meal, feather meal, and rock phosphate to create a balanced fertilizer and growth stimulant.
If you use natural liquid fertilizer, follow the instructions on the label for mixing rates and instructions for use. Generally, most liquid fertilizers are applied either by mixing the product in a watering can and watering by hand, or by using a fertilizer distribution system with hose tip to automatically supply the fertilizer with the irrigation water.
Liquid fertilizers are best absorbed if the plants growing in their containers are not stressed. Do not fertilize your plants if they wither or suffer from heat stress. Water them first, a few hours before fertilizing to maximize your nutrient absorption.
Although the excessive use of organic liquid fertilizers for gardening in containers is rarely possible in terms of plant health, it can be difficult for the budget to overdo it. Do not use more than what you need. Most liquid fertilizers should be applied every two to four weeks during the growing season.
