Tree Secret is a non-synthetic, carbon-based tree fertilizer sold in 64-ounce jugs. It is pitched as a biologically correct alternative to high-nitrogen chemical lawn fertilizers, which the brand says push weak, fast growth that thins cell walls and invites disease, wind damage and insects. The label calls for two applications a year to help a struggling tree and one a year for maintenance, and says it also works on bushes and evergreens. It is a niche product with a devoted following rather than a mainstream granular tree spike, and its main trade-off is that it is a liquid concentrate applied on a schedule rather than a slow-release spike you set and forget.

Owners rate it very highly and many describe reviving trees they thought were lost. Praise centers on visible new growth and greener foliage after a season of use. Criticism is thin, mostly about the effort of mixing and applying it and wanting faster results.
Tree Secret is a biologically correct, non-synthetic fertilizer made for trees. It was formerly known as Save-A-Tree. It is a small-batch, undiluted, carbon-based blend of readily available tree nutrients.
It is intended for trees, bushes, plants and evergreens. Unlike the nitrogen in most chemical lawn fertilizers, it is not meant to force the rapid growth that thins trees' protective cell walls and leaves them open to disease, wind damage and insects.
Use it twice a year to help save a dying tree. Use it once a year to maintain good tree health.
