Lawns & landscape.
Measured clearly.
Seed, fertilizer, lime and fabric calculators for outdoor coverage projects.
Turn a physical garden into checkable quantities.
Landscape products are labeled by coverage or application rate. These tools keep that rate beside the measured area, making it easier to buy whole bags or rolls without turning a label recommendation into guesswork.

4 focused tools
Lawn seed
Estimate grass seed from lawn area and a product-specific seeding rate.
Fertilizer
Calculate fertilizer product needed from area, nitrogen target and the bag's nitrogen percentage.
Garden lime
Estimate lime product and whole bags from area and a soil-test application rate.
Landscape fabric
Estimate landscape fabric area and linear feet with seam overlap.
A practical sequence
- Measure net treatment area.
- Read the exact product rate or soil-test recommendation.
- Calculate product quantity and round packaging sensibly.
- Calibrate application equipment before covering the full area.
Common planning mistakes
- Using total lot size instead of treated area.
- Confusing nutrient pounds with fertilizer-product pounds.
- Applying lime without a soil test.
- Adding extra seed beyond label rates.
Lawns & landscape FAQ
Why does fertilizer percentage matter?
The nutrient recommendation is for pounds of nutrient, while the bag contains only a percentage of that nutrient.
Can these results replace product labels?
No. Labels control rates, timing, safety and legal use; the calculators only perform the quantity conversion.
