*Guides differ on whether you can plant this month
**Some differences between sources on exact dates when to plant, but they all said you can plant sometime this month.
***The Central Texas Community Garden Manual says plant seeds indoors this month, and the other guides say wait until February or mid-March and plant directly. I've put cilantro seeds out starting in January, so I think anytime in March you want to plant them is fine. No need to wait.
