Tomato Fertilizers Buying Guide
Besides the main specifications listed above, there are other important factors related to tomato fertilizers as well. The first step to deciding which type of fertilizer is best for your tomatoes is to take into consideration these following things.
The Frequency of Fertilization
The first question that usually comes up from new gardeners is how often they should fertilize their tomatoes. Honestly, each tomato plant requires a different level of care and attention. You need to figure out the feeding rhythm to your tomatoes by trial and error.
There are numerous options of fertilizers out there with different speeds of nutrient absorption and release. There are typical powder ones, spikes as solid fertilizers, bone meal. You decide the frequency of feeding your plants, depending on which type of fertilizer you use.
It is crucial to get familiar with some of the common fertilization techniques before you begin your tomato growing journey. There are four popular methods: side-dressing, top-dressing, and foliar spraying.
Side-dressing is when you dig into the soil and put the fertilizers around the side of the tomatoes. Top-dressing simply means that you put the fertilizer on the top. Or you can simply mix it with water and spray on the leaves as a foliar spraying method.
This is the most important thing you need to look for when choosing the most suitable fertilizer for your tomato garden. Pay attention to three dashed numbers clearly shown on the label of each product, such as 4-6-3.
These numbers represent Nitrogen, Phosphorus, and Potassium. Normally, people don’t know how to determine the nutrient content of their soils. So avoid buying rich-nitrogen fertilizer on the first go, since most of the soil naturally contains a high nitrogen level.
How to Use Tomato Fertilizer?
When applying fertilizer while planting tomatoes, blend the tomato plant manure thoroughly with the soil at the base on the planting holes, at that point place some unfertilized soil over this before setting the tomato plant into the planting hole. If it happens that the fertilizer gets into contact with the roots, the tomato plant will get burnt and won´t grow.
While putting fertilizer onto the tomato plants as soon as the fruits begin setting, ensure the tomato tree gets watered properly. If it happens that the tomato plant wasn’t watered adequately prior to applying the fertilizer, it can suck excess of the fertilizer and result in the plant drying out.
As soon as you finish watering, pour the fertilizer on the ground at about 6 inches away from the plant. Putting fertilizer near the base of the tomato plant can lead to the fertilizer diffusing onto the roots or stem causing the tomato plant to dry.
