Granular Fertilizer

Granular is a dry fertilizer applied using a spreader.  It has many benefits, but one that outweighs the rest is that you get to see the actual fertilizer as you apply it. You can easily tell where you have applied and where you have not.

Granular fertilizer is a slow-release fertilizer that feeds your squash and cucumber plants for a longer period.  You may only use this fertilizer once or twice a year.

Unlike the slow-release fertilizers, the quick-release ones release nitrogen into the soil almost immediately after application.  The quick-release fertilizer is best used when you want to fix your soil immediately.

Organic fertilizer is always better than inorganic, regardless of the plant you are growing. You can buy organic fertilizers from the nearest organic center.

Organic fertilizers are all-natural and non-toxic to animals, but that doesn’t mean you allow your dogs or cats to ingest them. These fertilizers do not burn your crops or form a crust on your soil like the inorganic ones.
