Plant Spacing Calculator
Proper plant spacing is the difference between a thriving garden and a crowded, disease-prone one. This calculator tells you exactly how many plants you need to fill a garden bed based on the recommended spacing for your chosen plant. It supports both square and triangular (offset row) layouts — triangular spacing fits about 15% more plants in the same area and is ideal for dense groundcovers and ornamentals.
Use Calculator →Garden Mulch Calculator
A 2–4 inch layer of mulch suppresses weeds, retains soil moisture, moderates soil temperature, and improves your garden's appearance. Getting the quantity right prevents both short-changing coverage (leaving weeds a foothold) and over-applying (which can suffocate roots and cause crown rot). Enter your bed dimensions and desired depth to get cubic yards and bag counts.
Use Calculator →Garden Watering Calculator
Most vegetable gardens and flowerbeds need 1 inch of water per week — from rainfall, irrigation, or a combination. This calculator converts your garden's area and weekly water need into gallons and liters, so you know exactly how long to run your sprinkler or drip system. Adjust for rainfall received to avoid over-watering.
