Plant Guide
Everything we're growing — what they need, when they fruit, and how they get along together.
🍅 Cherokee Purple Tomato
Variety: Cherokee Purple is an indeterminate heirloom — meaning vines (not a bush), continuous fruit set possible, needs strong support. Central Texas Gardener (PBS Austin) names it among their favorite indeterminate types.
Fruit: Large beefsteak tomatoes, dusky purple-red with dark "shoulders," classic rich heirloom flavor. Typically 8-12 oz each.
Harvest window: ~70-90 days from transplant (so first ripe tomatoes around late July if planted May 16-17).
The Pflugerville reality
Heirloom tomatoes like Cherokee Purple are sensitive to intense heat. The Texas A&M AgriLife guidance for blossom drop is clear: when overnight temperatures stay consistently above ~75°F, the flowers drop without setting fruit. In Pflugerville, that typically means:
- May 16 to mid-June: normal flowering + fruit set
- Mid-June to late August: the heat-pause. The plant stays alive but stops setting new fruit. Existing fruit continues ripening.
- September to first freeze (late November): the fall flush — new flowers and fruit again as nights cool.
Knowing this lets us plan: we cover the bed with shade cloth in June, keep mulch deep, and don't panic when fruit set pauses.
How we care for it
- Trellis: 16-foot cattle panel + T-posts. Cherokee Purple vines reach 6-8 feet. Tomato cages are not enough.
- Spacing: 24 inches between plants (3 plants along the long side of the bed).
- Water: Soaker hose under mulch. About 1 inch of water per week, increasing in summer heat. Consistent watering prevents blossom end rot.
- Feed: Organic Espoma Garden-Tone at planting. Sidedress again at first fruit set (~4-6 weeks later).
- Shade cloth: Deploy when sustained 95°F+ arrives (typically mid-June).

🌶️ Jumbo Jalapeño Pepper
Variety: Jumbo Jalapeño — larger fruit than standard jalapeños, classic medium-heat flavor.
Heat behavior: Peppers handle Texas heat much better than tomatoes. Expect continuous production through summer.
Harvest: 60-90 days from transplant. Pick when peppers are 3-4 inches long, still firm and shiny. Leave on the plant longer if you want them to turn red (sweeter + slightly hotter).
How we care for it
- Placement: South end of the bed (gets earliest sun, away from tall tomato shade).
- Water: Same as tomatoes — consistent, mulched.
- Feed: Same Espoma Garden-Tone schedule.
- Harvest gloves: Capsaicin is strong on hands. Wear gloves or wash hands well after handling.
🫐 Prime-Ark Freedom Blackberry
Variety: Prime-Ark Freedom — the world's first thornless, primocane-fruiting blackberry. "Primocane-fruiting" means it produces fruit on first-year canes (this year's growth), unlike traditional blackberry varieties that need a full year to establish before bearing fruit. Texas-adapted; heat and humidity tolerant.
Why thornless matters: Safer with Lulee and Rowan in the yard — no thorny canes to catch on.
First fruits: Expected late summer / fall 2026 on primocanes — so we should see berries within months of planting.
Why a separate container
Blackberries prefer slightly acidic soil (pH 5.5-6.5), while tomatoes prefer near-neutral (6.0-6.8). Pflugerville's native soil is alkaline (pH 7.5-8.0), so the blackberry lives in its own half-whiskey-barrel with potting mix amended with elemental sulfur to bring the pH down. This also keeps the perennial blackberry separate from the annual tomato rotation.
How we care for it
- Container: Half-whiskey-barrel (already on hand) with drainage holes drilled. 20+ gallon capacity.
- Soil: General potting mix + ¼ cup elemental sulfur per cubic foot of mix (about ¾ cup total).
- Sun: Full sun ideal, with afternoon shade in Pflugerville summer (similar to tomatoes).
- Water: Consistent moisture — containers dry faster than ground beds.
- Feed: Espoma Berry-tone (or Garden-tone) every 6-8 weeks during growing season.
- First-year pruning: Pinch cane tips when they reach 3.5-4 feet to encourage lateral branching (more fruit potential).
A second blackberry plant is planned for the fall budget — so we'll have two by next spring.
🌿 Companion plants for the tomato bed
Our tomatoes don't grow alone — they share the bed with herbs and flowers that help them. According to Texas A&M AgriLife research (Joseph Masabni, AgriLife Today, 2023), the most useful tomato companions are basil (as a disease-indicator), marigolds (deter hornworm-laying moths), and parsley.
Role: Disease-indicator + pollinator attractor. Masabni notes basil shows powdery mildew and other diseases before they show on the tomato plant — making basil our early-warning system. (Despite the folk wisdom, AgriLife research found basil does not change tomato flavor — but it's still worth growing.)
Use: Pesto, caprese salad, tomato sauces. Pinch flowering tops to keep leaf production going.
Safety: Dog-safe per ASPCA.
Role: The strong scent deters the hawk moth that lays hornworm eggs. Marigold roots also release a compound toxic to soil nematodes (microscopic pests).
Placement: Around the tomato plants, established at the same time so they're ready when pests arrive.
Safety: Generally safe for dogs — mild GI upset only if eaten in large quantity.
Role: Classic tomato companion. Attracts beneficial insects. Use the flat-leaf variety — more flavor than curly.
Note: Parsley does best in cool weather in Central Texas — it'll thrive April-June, slow down in peak summer, and rebound in fall.
Safety: Dog-safe per ASPCA.
Role: Aphid trap (aphids prefer nasturtium to tomato — they sacrifice themselves). Bright orange/yellow flowers attract pollinators. Edible peppery leaves and flowers — great in salads.
Placement: Edge of the bed where the trailing habit can spill over.
Safety: Dog-safe.
Chives are excellent tomato companions except when there's a dog in the yard. Chives (and all Allium-family plants — onions, garlic, leeks) contain N-propyl disulfide, which can cause hemolytic anemia in dogs. Even small amounts of ingestion can be dangerous for Lulee.
We're substituting basil, parsley, marigold, and nasturtium — all dog-safe and all good tomato companions. If Sam wants chives in the kitchen, we can grow them in an elevated container on the back porch where Lulee can't reach.
🌿 What we're NOT planting (and why)
Sam loves cilantro. But cilantro bolts (flowers and stops producing leaves) very quickly in Central Texas heat — by late May it's already on borrowed time. The fix: plant cilantro in October in the shadier yard area for harvest through winter and spring. See the Fall Garden page.
Tomato leaves and stems contain solanine (mildly toxic to dogs in quantity — ripe red tomatoes are safe). Jalapeño plants are in the same family. Practical reality: most dogs ignore tomato foliage entirely, and the raised bed makes access harder. We'll keep an eye on Lulee around the garden but the risk is low. ASPCA recommends contacting their poison control line at (888) 426-4435 if you ever suspect ingestion.
