Garlic Seed Calculator


Without a doubt the most frequently asked question is "How much seed garlic do I need?"

Here is the formula we use when planning our plantings:


Width (in feet) times 2  x  Length (in feet) times 2 = Number of cloves needed 


or  W2 x L2=Number of cloves needed


 A 4' x 4' bed will hold up to 64 plants with a 6 inch spacing. Figure on Softneck varieties averaging about 24 seeds to the 1/4 pound. Hardnecks will average about 14 seeds per 1/4 pound. These are averages so if you want to insure that you fill your space order just a tad more.
