How many seeds do I need per square foot?
Also question is, how many seeds do I need to plant?
In general, two to three seeds should be planted per hole. Seeds do not have 100% germination rates, so not every seed planted will sprout. Overseeding holes, cells, or pots will help ensure that the number of plants you desire will grow (or more!).
Also question is, how do I figure out how many plants I need per square foot?
Multiply the square footage of the planting bed by the plants needed per square foot to determine the number of plants needed. When using plants with different spacing requirements in the same area, estimate the square footage you will need for each plant. Number of Plants per Sq. Ft.
For example, if you wish to plant a new Kentucky bluegrass lawn, the seeding rate is 2 to 3 pounds of seed per 1,000 square feet. If you are planting a tall fescue lawn, the recommended rate is 8 to 10 pounds per 1,000 square feet.
