How Often to Use Miracle-Gro on Indoor Plants

The solution can be used every 7 to 14 days for fast-growing plants and less frequently for slow-growing plants.

Orchid

In fact, they even require special fertilizer blends with specific nutrients. According to Miracle-Gro, 1/4 teaspoon of their orchid formula should be added to each gallon of water and applied every two weeks during the orchid’s active growing season. During the orchid’s rest period, it should be applied in the same ratio every four weeks.

All-Purpose Granules
