Fertilizer Tablets

Enlarged view.  Each tablet is about 1/2" high and 3/4" in diameter.  Each tablet is 10 grams.                        Nitrogen, Phosphate, Potash (NPK) 20-10-5

Features of the Tablets

Safe:  The slow-release nutrients in the tablets are compressed under many tons pressure.  The tablets do not dissolve; instead, the nutrients are gradually released by the action of soil bacteria.  Therefore, the risk of burning roots is negligible. 

Effective:  These tablets provide 8 times the plant's need for nitrogen, 13 times the need for phosphorus, and 4 times the need for potassium required to quadruple the size of a seedling during the first year after transplanting.  But little of the surplus nutrients are wasted; most are slowly absorbed by the tree's roots.

Versatile:  These tablets work in any kind of soil so long as there is sufficient moisture to permit root growth and sufficient soil bacteria to break down the tablets.

How to Use:  Dig hole, position plant at the proper level and backfill halfway up the root ball.  Place one 10-gram tablet 1 to 2 inches away from roots and 4 to 6 inches below the surface of the soil.  Do not place at the bottom of the hole.  Continue backfilling, tamp around plant lightly and water thoroughly.

Cost: Each 10-gram tablet costs 15 cents.  (2018 prices)
