Starter Fertilizer for Transplanted Seedlings and Repotted Plants

FoxFarm Happy Frog Jump Start is a dry fertilizer formulated for transplanted seedlings and repotted container plants. This 4 lb package supplies phosphorus for early plant growth, calcium to support cell-wall development, and mycorrhizal fungi to help increase root efficiency.

When seedlings move into their next growing space or container plants need a larger pot, match their nutrition to this early growth stage. Jump Start is designed for these planting transitions, with a proprietary fertilizer blend and mycorrhizal fungi that may enhance nutrient uptake and water absorption.
