Types of Fertilizer
Besides the combination of these three vital nutrients, fertilizer also comes in one of two
major categories: fast release and slow release. As you have probably already deduced, a
fast release formula means that the nutrients are available to the plant immediately. This is
essential when the plant needs a sudden jolt of nutrients to bring it back to a level of good
health.
When using fast-release formulas, you have to remember that, as the name implies, nutrients
are going to be bombarding the plant all at once and in a large volume. If you do not plan ac-
cordingly, your plant will suddenly perk up and then abruptly die from being over fertilized.
In order to compensate for this, you have to be ready to water the plants more than usual so
the sudden blast of fertilizer doesn't literally burn the plant up.
Slow release is more for routine fertilization when the plants just needs a constant, but slow
and steady feeding of nutrients to keep its levels where they should be.
It is possible, and often practiced, that both slow release and fast release fertilizers can be
used together. Again, the presence of fast release fertilizer is going to extract more moisture
out of the soil than the plant is accustomed to so excess water will still need to be applied in
order to maintain a healthy plant.
