Why are some columns showing "โ€”"?

Start Indoors shows "โ€”" because Garlic is typically direct sown outdoors rather than started indoors. It germinates quickly and doesn't transplant well.

Transplant shows "โ€”" because Garlic is best direct sown where it will grow. Transplanting can disturb the roots and slow growth.

Direct Sow shows "โ€”" because Garlic benefits from being started indoors first, then transplanted after the last frost.
