Frequently asked questions

How do I find the mature spacing for my plants?

Check plant tags, seed packets, or gardening guides for recommended spacing. This is usually the distance needed between plants when fully grown.

Should I use square or triangular spacing patterns?

Triangular spacing fits more plants in the same area and provides better space utilization, while square spacing is easier to plant and maintain.

What if my garden area is an irregular shape?

Break irregular areas into rectangular sections, calculate each separately, then add the results together for your total plant count.
