Should you use a slow release lawn fertilizer?

When you are trying to fertilize your lawn, should you use a quick release fertilizer or a slow release fertilizer?

Slow release fertilizers contain fast release fertilizer granules that start releasing fertilizer soon after they hit the ground. Once the fast release granules are depleted, the slow release granules release more fertilizer. This process continues until the fertilizer is fully depleted.

Slow release fertilizers allow you to fertilize your lawn less often, which saves you time and money. However, slow release fertilizers are more expensive than fast release fertilizers.

Fast release fertilizers release fertilizer right away. Fast release fertilizers can cause damage to your lawn, especially to newly seeded or newly planted areas, so they are not recommended for these areas.

Fast release fertilizers are more expensive than slow release fertilizers because you need to fertilize your lawn more frequently.
