Insect Controls
Target surface feeding insects (including ticks and fleas), tree/shrub insect controls and our first round of bug shields to keep the pest out.

Organic Fertilizer and soil additives
Rebuild your soil profile or correct your PH. A soil test allows us to take a deep look and see what's missing.

Tree/Shrub Insect Controls

Other services upcoming:

Aeration/Seeding
