How-to: Tomatoes — Rio Ranch

01 Quick spec

Planting windows (spring + fall)

18–24"

Spacing, caged or staked

60–85d

Transplant to first ripe fruit

North-TX planting window: set transplants out after the last frost (~Apr 1) for the spring crop, and start a second round in mid-summer (transplant Aug) for a fall harvest before the first frost (~mid-Nov). Pollen aborts above ~90°F, so both crops are racing the heat.

02 Growing it here

Two seasons, one enemy: heat

North Texas gives you two windows, not one. The spring crop goes out after Apr 1 and sets fruit through May and June; once days top 90°F, blossoms stop setting. A fall crop transplanted in August ripens through the cooling weeks up to the ~mid-Nov frost. Lean on heat-set varieties (Phoenix, Solar Fire, Florida 91, Sun Leaper) and small-fruited cherries that shrug off heat.

Transplant, never direct-seed

Always set out transplants — start seed indoors 6–8 weeks ahead (Feb for spring, June for fall). Plant deep, burying two-thirds of the stem to root the buried portion. Space 18–24" in rows ~3–4' apart and cage or stake at planting so you're not wrestling a sprawling vine later. Mulch heavily to hold moisture and even out soil temperature.

03 The year

Month	What
Feb	Sow spring crop indoors under lights (6–8 wks before set-out).
Apr (after ~Apr 1 frost)	Transplant spring crop; cage/stake; mulch.
May–Jun	Peak fruit-set and first harvest before the deep heat.
Jun	Sow fall crop indoors.
Aug	Transplant fall crop for autumn fruit-set.
Oct–mid-Nov	Fall harvest; pull green fruit before the ~mid-Nov first frost.

04 Problems & what to watch

Pests & disease

Tomato hornworms strip foliage overnight — hand-pick (look for black droppings). Blossom-end rot (sunken black bottoms) is a calcium/uneven-water problem — mulch and water steadily. Watch for early blight and spider mites, both worse in heat and drought stress.

Heat

Above 90°F days / 75°F nights flowers drop and fruit won't set — this is why we run spring and fall crops, not one long summer crop. Use 30% shade cloth over plants in July–August and water deeply to keep them alive through to the fall set.

05 Harvest & beginner mistakes

Stage	Do this
Picking	Harvest at the "breaker" (first blush) stage and ripen on the counter — beats the birds and cracking.
Frequency	Pick every 2–3 days at peak; over-ripe fruit invites pests.
End of season	Pull whole green-fruited plants before frost; ripen indoors.

Beginner mistakes to skip: planting one big spring crop and losing it all to July heat; caging too late; overhead watering (invites blight) instead of soaking the roots; and skipping mulch, which is what causes most blossom-end rot here.
