Expert Insights
Smart analysis for your Landscaping project
Mulch Depth by Purpose
Weed suppression: 3-4". Moisture retention: 2-3". Decorative: 1-2". AI recommends depth based on your project goals.
Gravel Base Requirements
Driveways: 4-6" compacted base + 2-3" gravel. Paths: 2-3" base + 2" gravel. AI adjusts for vehicle vs foot traffic loads.
Soil Amendment Calculator
AI factors your soil type (clay/sandy/loam) and plant needs to recommend compost and amendment quantities — not just volume.
Calculation Formula
Volume (cu ft) = Length x Width x (Depth / 12)
Cubic yards = Volume / 27
Tons = Cubic yards x Density factor (1.4-1.7)
