Xtreme Gardening Controlled Release Fertilizer Paks, 500 Count
Nurseries, landscapers and reforestation crews plant by the hundreds, and feeding each one by hand is not practical. This 500 count bag puts one measured dose in reach for every planting hole. Each packet holds 10 grams of polymer-coated granules with a 12-10-10 analysis. The coating meters nutrients out slowly as soil moisture passes through it. A single packet keeps feeding for up to 12 months. Xtreme Gardening developed the release method through its parent company, Reforestation Technologies International. According to the company, under 1 percent of the nutrients escape to the environment. That keeps feed where roots can reach it instead of in runoff. The packets are biodegradable, so nothing needs to be dug back out. The balanced ratio supports root growth, foliage and flowering together. Crews can drop packets into holes as they plant, with no spreaders or scoops to manage. Transplants, perennials, bulbs, vegetables and potted ornamentals are all listed uses.
Using Fertilizer Packets Across Large Plantings
Stage the bag at the planting site so packets go into each hole as it is dug. Place one packet at the bottom or side of the hole before setting the plant. Leave a little soil between the packet and the root ball for young, tender roots. Backfill, firm the soil and water each plant thoroughly. Steady moisture through the first weeks gets the release under way. For container production, set one packet into the mix beside each liner at potting. For existing landscape plants, push packets into the soil along the drip line. Skip extra granular feeding on packeted plants during that first season. Track growth and leaf color across the block to spot any plants that need attention. Reseal the bag between uses so humidity cannot reach the remaining packets. Store it off the floor in a cool, dry area.
