Although the calendar says March, here in St. Louis and other parts of the Midwest we have 10 inches of snow outside. It is hard to think about gardening when the ground is blanketed with white.
Spring will come whether we are ready for it or not. The official first day of Spring (Vernal equinox) is only 2 1/2 weeks away (March 20).
Even though the last frost date is different for each time zone it is now the time to prepare for gardening. If you can’t do much outside because of cold or snow, you can plant those seeds or order your plants, fertilizer, etc., so you have them when the weather is right.
Old Man Winter can even hit the southern parts of the country in March. My son lives in Dallas where they were hit with a snowstorm last night. There was enough snow to build a snowman. Check it out at http://tcaball.com/.
