Our small batch, extra potent blend of readily available tree nutrients are exactly what your trees, plants, and bushes need to revitalize and look great for years to come. The competition doesn't come close!

  • Nitrogen found in most chemical lawn fertilizer is largely responsible for the unnatural rapid growth that weakens trees by thinning their protective cell walls; this opens the door for disease, wind damage, and bug infestations... 
  • Plants and bushes need the same nutrition as slow growing trees. Give your yard a serving of this ultra potent, undiluted, carbon based fertilizer and watch in amazement as your trees thrive and your landscape transforms into a lush paradise.
  • Excellent results on all trees, bushes, and evergreens! Use 2 times per year to save a dying tree and 1 time per year to maintain good tree health.
  • Happy trees have less problems. This stuff works.

What Makes Us Different?

Frequently Asked Questions

What makes Tree Secret® different from other fertilizers for trees?

Most tree fertilizers on the market are either a general lawn fertilizer repackaged with a tree label or a granular fertilizer loaded with synthetic nitrogen that forces fast, weak growth. Tree Secret® was formulated specifically for what trees actually need. The 4-1-0 ratio delivers nitrogen along with sulfur, phosphorus, and available nutrients derived from all-natural sources like alfalfa and rock phosphate. Instead of thinning cell walls with chemical fertilizers, Tree Secret® feeds the microbes in your root zone so they can break down and deliver nutrients at a biological level, supporting stronger root growth, better nutrient availability, and healthy growth that lasts. That's why we consider it the best fertilizer for trees on the market.

Can I use Tree Secret® on shrubs, bushes, and fruit trees?

Absolutely. Tree Secret® works on all types of woody plants, including deciduous trees, evergreens, fruit trees, shrubs, and bushes. Plants and bushes need the same nutrition as slow-growing trees, so a single application of this complete fertilizer gives your entire landscape what it needs. Use it twice per year on stressed or dying trees and once per year for general maintenance. For larger trees, base your dosage on trunk diameter to make sure you're applying enough.

When is the best time to apply fertilizer for trees, and how do I know if my trees need it?

The best time for fertilizer application is in early spring when trees are coming out of dormancy and again in late summer or early fall to help them store nutrients before winter. Avoid fall fertilization too late in the season, as it can stimulate new growth that won't harden off before frost. For established trees, one to two applications per growing season is typically enough. If you're unsure whether your trees need additional fertilizer, a soil test is the best place to start. Your soil test results will show your soil pH and nutrient levels, so you know where the gaps are. Signs of nutrient deficiency include pale or yellowing leaves, stunted new growth, and a thin canopy. Tree Secret® is an excellent foundation for any tree care program because it delivers essential nutrients without the salt buildup that comes with synthetic options.
