These fertilizers are spread around the soil surface, then coated with soil or compost.

This makes them a much better supply of nutrients for compact trees, plants, and shrubs than for large trees or lawns.

Consequently applying fertilizer after planting only has an effect on The present phase and any phases thereafter, in exactly the same way that implementing at precisely the same day as planting influences These levels.
In the event the soil test reveals that every one three nutrients are existing in the roughly equivalent quantity, go with an all-function fertilizer with the NPK ratio of one:1:1. These fertilizers contain a balanced nutritional profile that is suited to flowers, veggies, shrubs, trees, and lawns.
