Waco Garden Calendar: March


A picture of beets.  I got this picture from Pixabay, as I never grew beets in Waco.

Below you will find a list suggested plant dates for March!

March 23 is average date of the last spring from in Waco.  Instructions on seed packets will often say "plant after danger of frost." Well, ok, when is that? And how cold does it have to get for that frost to kill my plants?

Well, I looked it up and found that a frost of 29°F to 32°F will kill tender plants, but not damage most other plants. 25°F to 28°F is destructive to most vegetation, and frost 24°F and colder is REALLY BAD.  So check the weather this month when deciding how to protect your plants.

*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.
