Plantra® Fertilizer Packets
To keep your seedlings well-fed after planting we offer easy to use “slow-release” fertilizer packets that can be placed in the planting hole when your new seedlings go in the ground. The 30g “Booster Pak” with its 22-10-7 blend is specifically formulated for hardwood seedlings.
For conifer seedlings we recommend the 10g “RT Pak” 18-9-9-9 [S] mix.
Product Specifications
Directions:
Place fertilizer packets 1.5in to 2in apart from the seedling roots at a depth of 1.5in to 2.0in. Locating the Pak in an organic layer or next to the organic material can improve results.
