I think spring is finally here. At least with these much warmer temperatures, the outside chance of a very late frost has dwindled significantly.
The warmer temperatures are coaxing the many wildflowers into growth spurts. My numerous amaryllis and St. Joseph lilies are blooming non-stop and my Dutch iris blooms are already a memory. My 10-foot tall angel trumpet growth succumbed to the January freeze, but only the part above ground was affected. All of them have again sprouted from the roots, looking healthy and strong. I gave them a little slow release organic fertilizer to help them on their way.
The lion’s ear in my front yard had reached over six feet last summer, but it too froze back to the ground. It is now sending out sprouts, as are the four or five varieties of lantana, plumbago, night blooming jasmine, and Texas star hibiscus.
I did lose my ginger root plants (Zingiber officianale) …at least they’re not up yet. But my ginger lily (Hedychium sp.) is looking so well that I have already divided it.
Based on all that circumstantial evidence (also using the time-tested lore of budding pecan trees), I would venture to say that spring has arrived.
The National Oceanic and Atmospheric Administration (NOAA) publishes a “Day of the Last Spring Freeze” map, which roughly corresponds to the U.S.D.A. Cold Hardiness Zone Map. The USDA map is the standard which gardeners and growers can use to find out which plants are most likely to thrive in a location.
Both maps draw a ragged line across Montgomery County. The jagged line, which runs southwest from Cleveland in the east to Magnolia in the west, currently divide Montgomery County almost in half. The northern part, which includes about three-fourths of Conroe, all of Willis, Cut and Shoot, Montgomery, and about half of Magnolia, is in Zone 8B. The southern part is in Zone 9A. The difference is that the area designated as 9A has become, on average, about 10 degrees warmer than the northern part of the line.
The southern part includes The Woodlands, Kingwood, New Caney, about a fourth of Conroe, Oak Ridge North, Shenandoah, Porter, about half of Magnolia and Spring. The line has two long prongs, one which stretches north almost to Lake Conroe, and another that almost reaches Dobbin Lake.
My plants can’t read maps, but they generally do know when the ground and ambient air is warm enough to stick their little green arms out of the ground. Sometimes, they might be surprised, but chances are, they’re not going to be this year.
So, you can start trimming back the dead parts of your plants. If you’re doing compost, the pruned parts make a great addition. Just make sure you cut all the hardwood stems into very small pieces or shred them.

In the vegetable garden, it’s almost too late to plant tomatoes, although if you’re brave enough, you can try. Early Girl tomatoes produce in about 55 days from the day you put them in the ground. That means, if you set them in today, they’ll be producing around the middle of May. Longer producing varieties may not produce until June. Then nighttime temperatures may have risen so high that the tomatoes will stop setting fruit.
Many people planted beans the first week of March and cucumbers the second or third week. Mine are about 8 inches high already, although my cucumbers just sprouted last week. The Montgomery Master Gardener website (http://www.mcmga.com) has a printable calendar on what vegetables to plant when.
