Planting & Soil Science

Don't excavate your profits away. Learn how to calculate California Bearing Ratio (CBR), specify biaxial geogrids, and drastically reduce base aggregate depths when designing hardscapes over weak soils.

A green roof isn't just a garden; it's a massive sponge. Learn how to calculate transmissivity rates, specify the correct drainage mats, and prevent catastrophic waterlogging on flat rooftop landscapes.

Slopes fail when geometry ignores physics. Master the geotechnical principles of grading by understanding the Angle of Repose, maximum mowable grades, and how to engineer stable terraces that resist erosion.

Don't drown your plants in amended soil. Learn the physics of soil bulk density, macro-porosity, and how to prevent the disastrous "Bathtub Effect" when amending heavy clay landscapes.

Stop planting trees in concrete coffins. Discover the biological math behind urban tree survival, including how to calculate required soil volumes, prevent sidewalk heaving, and utilize structural soils effectively.

Designing a rooftop garden? Don't risk a structural collapse. Learn the critical calculations for saturated soil weights, stormwater retention, and wind uplift required for safe and sustainable green roof design.

Prevent catastrophic hardscape failures. Learn how to accurately calculate soil load-bearing capacity, subgrade compaction, and live traffic stresses for commercial plazas and emergency access routes.

Avoid costly plant shortages and overcrowded beds. Learn how to accurately calculate plant quantities, factor in mortality rates, and master geometric planting patterns for commercial and high-end residential landscape projects.

Earthwork is the most expensive variable in landscape construction. Learn how to manage swell factors, optimize heavy machinery usage, and execute precision site grading to protect your project budget.

Healthy plants require precise soil chemistry and structure. Discover how to accurately calculate bulk soil volumes and organic amendments to create the perfect growing substrate without over-ordering materials.
