Feed all the plants in your garden with the Miracle-Gro LiquaFeed All Purpose Plant Food Advance Starter Kit. This plant food and feeder set grows plants twice as big!* In addition, this garden product makes feeding as easy as watering. Use with all types of in-ground or container flowers, vegetables, trees, and shrubs. To apply, attach a garden hose to an outdoor spigot then connect the Miracle-Gro LiquaFeed Feeder to the other end. Insert the plant food bottle into the feeder then rotate until vertical and turn the knob to FEED. Turn on the water and begin feeding! Plants should be fed every 1-2 weeks. For the best results, feed plants by applying to the soil at their base, spraying each spot for a few seconds until the soil is saturated. Shake well before each use, and only apply this concentrated liquid plant food using a LiquaFeed feeder. The starter kit comes with one Miracle-Gro LiquaFeed Feeder and one 16 oz. bottle of Miracle-Gro LiquaFeed All Purpose Plant Food, which feeds up to 400 sq. ft. of garden area. *vs unfed plants.
