What Does NPK Mean?
When you buy fertilizer, you will see an NPK ratio on the packaging, for example, 15-10-10.
This ratio means the fertilizer has 15% nitrogen, 10% phosphorus, and 10% potassium.

All plants need these three elements to grow.
Some types of plants need more of these elements than others, which is why some contain different ratios.
This ratio is listed on all synthetic fertilizer packaging and most organic fertilizers.

Some formulas promote blooms, while others strengthen foliage or root growth.

Environmentally conscious gardeners and farmers will lean heavily on organic ingredients.
Consider using organic fertilizer for fruits and vegetables intended for personal consumption.
In many circles, compost is an organic fertilizer; in other circles, it’s a soil amendment.
Regardless, one of its purposes is to provide nutrients to the soil and plants.
Compost is organic and easiest to add before planting.
It works best for long-term soil improvement.
Most vegetable gardens are planted in the same place yearly, depleting nitrogen.
Natural Mulch
Natural mulch serves as a finishing touch to flowerbeds and landscape plants.
Liquid fertilizer is your best bet if you oughta get nutrients to your plants immediately.
If you sprinkle granules on your soil with water and time, the plant will gradually absorb the nutrients.
