Q.
We read your early spring article in the RJ on tomatoes and planted 6 plants in
mid-March. We planted a mix of ‘Sweet
100s’, ‘Champion’ and another plum tomato.
We have been watering, using Miracle Gro for tomatoes and watching them
closely. The plants appear stunted. We have them in cages, and they have only
grown a short distance up the cage. Any suggestions?

| The smaller tomatoes, pear, cherry and grapes are always a sure thing in Las Vegas. The larger tomato is ‘Black from Tula’, an heirloom type. When the spring season is long and cooler, tomatoes do better. |

Planting dates for tomatoes in our climate can range from mid-February to mid-March.
Watch the weather and use your weather app on your phone. It’s been cold lately.
Wait for temperatures to warm up a bit. Tomatoes are a “warm season” crop, and
they prefer soil and air temperatures a bit warmer than our spring provides at
times. Our spring temperatures have been erratic. Low soil temperatures can
slow tomato growth even if the air temperatures are high.

About a week before you are to plant
tomatoes, cover the soil with clear plastic and seal the edges. This is so the
warm temperatures under the plastic don’t “leak out”. Warm the soil temperature
to at least 65 F in the top few inches. I would slit the plastic and plant at
that temperature. A soil thermometer stuck in the soil an inch or two deep
helps you to check it.

| Tomatoes can be started a bit earlier if the soil is covered with plastic and there is good weather. |
Raised beds in full sun warm up much
faster in the spring than those raised beds in the shadow of a wall or home.
Have two raised beds: one for early production in the spring and another for
later production.
