Calculators

Calculate how many pounds of fertilizer to apply based on lawn or garden area, target nitrogen rate, fertilizer analysis, and an optional application adjustment factor.

Calculate how many hedge plants are needed based on the total hedge length, recommended spacing, planting pattern, and expected plant loss allowance.

Estimate the amount of seed potatoes needed based on planting area, row spacing, in-row spacing, average seed piece weight, and a field adjustment factor for paths, gaps, and uneven planting.

Calculate how many potato seed pieces you can plant based on bed length, number of rows, spacing within rows, and spacing between rows. This helps estimate planting capacity for garden beds or field rows using common potato spacing practices.

Calculate how many onion plants fit in a bed or row based on planting area, row spacing, in-row spacing, and walkway allowance. Useful for bulb onions, bunching onions, and intensive bed layouts.

Estimate how many garlic cloves you can plant in a bed based on bed dimensions, spacing between cloves within rows, spacing between rows, and bed layout efficiency.

Estimate how much carrot seed is needed based on planting area, row spacing, in-row spacing, expected germination rate, and seeding method. The calculator returns the estimated seed weight required in grams, including adjustment for stand losses and planting method.

Estimate how many lettuce plants fit in a rectangular garden bed based on bed dimensions, spacing method, and pathway allowance.

Calculate how many strawberry plants fit in a bed based on bed dimensions, row spacing, plant spacing, and planting layout.

Calculate how many apple trees fit in a rectangular planting area based on row spacing, spacing between trees, and an optional access/path allowance.

Calculate recommended planting density for a fruit orchard based on row spacing, in-row tree spacing, planting area, and layout efficiency. The calculator estimates how many fruit trees fit in the available area using practical orchard spacing assumptions.

Estimate how many cucumber plants fit in a garden bed based on bed dimensions, row spacing, in-row plant spacing, and growing method.

Calculate how many zucchini plants fit in a garden bed based on bed dimensions, growing method, and spacing recommendations. This estimate uses typical in-row and between-row spacing for bush, compact, and vining zucchini varieties, with an optional access path adjustment.

Estimate how many squash plants fit in a garden bed based on bed dimensions, row spacing, in-row plant spacing, and growth habit.

Estimate how many pumpkin plants fit in a garden bed based on planting area, row spacing, in-row plant spacing, and vine size type. This helps plan realistic pumpkin spacing for bush, semi-vining, and vining varieties.

Calculate in-row corn plant spacing based on row width, target population, field area, and expected emergence rate. The result shows the recommended spacing between plants within each row.

Estimate corn plant population per acre using row spacing, in-row seed spacing, germination rate, and field emergence. This calculator helps convert planting geometry and stand-establishment assumptions into an estimated final plants-per-acre value.

Calculate in-row corn seed spacing based on target population, row width, field area, and expected emergence. This helps estimate the distance between planted seeds needed to achieve a desired final stand.

Calculate the germination rate as the percentage of seeds that successfully sprout, based on the total number of seeds tested and the number that germinated.

Estimate how many tomato plants fit in a rectangular garden bed based on bed dimensions, spacing between plants, spacing between rows, and tomato growth habit.

Estimate how many pepper plants fit in a rectangular garden bed based on bed dimensions, spacing between plants, spacing between rows, and walkway allowance.

Estimate the recommended vegetable garden size in square feet based on the number of people to feed, vegetable consumption level, gardening experience, and whether you want extra space for succession planting and crop variety.

Calculate recommended row spacing based on field width, number of rows, row width, and walkway clearance. This helps plan evenly spaced rows across a planting bed, garden plot, or layout area.

Calculate the estimated plant population per hectare based on row spacing, plant spacing, field area, and expected germination percentage.

Estimate the total amount of seed needed based on lawn or field area, seeding rate, expected germination, and overseeding intensity.

Estimate the seed required for planting based on field area, target plant population, expected germination, seed purity, and thousand seed weight.

Estimate the seed required per acre based on target plant population, expected germination, seed purity, and thousand-kernel weight.

Estimate the total amount of seed needed based on planting area, target seeding rate, expected germination, and expected field loss.

Estimate how much area a quantity of grass seed can cover based on seed amount, application rate, overseeding vs new lawn, expected germination, and spread loss.

Estimate the total seed weight needed based on planting area, seeding rate, expected germination, field loss, and unit system.
