Jack's Classic

Yes, this is a versatile, all-purpose formula. It is safe for a wide range of plants, including vegetables, roses, shrubs, and houseplants, thanks to its balanced nutrient profile.

Because it is highly water-soluble, it can be used for both soil drenching and foliar feeding. When applying to leaves, ensure you follow the dilution instructions to avoid potential leaf burn.

The 20-20-20 ratio provides an equal balance of nitrogen for foliage growth, phosphorus for root and flower development, and potassium for overall plant health. It is an excellent maintenance fertilizer for plants that require consistent, balanced nutrition.

Jack's Classic is designed to be highly soluble. While it dissolves best in room-temperature water, it will mix effectively in most conditions, leaving no residue in your watering can or sprayer.

Frequency depends on the specific needs of your plants, but generally, it can be applied every 1 to 2 weeks during the active growing season. Always refer to the label instructions for the specific dilution rates based on the plant type.
