Starting and Planting

In Chico (USDA Zone 9a), start seeds indoors 6–8 weeks before the average last frost (mid-to-late March). Sow ¼ inch deep in warm soil (70–85°F). Transplant after the last frost and when nights stay above 50°F—typically early to mid-April. Plant deeply, burying the stem up to the first leaves for strong roots. Space 2–3 feet apart in rows or containers. Sweetie’s vigor makes it excellent for raised beds or large pots on patios around town. Local nurseries often carry strong starts by spring.

Location and Soil

Pick a full-sun location in Chico with at least 8 hours of direct sunlight—your valley backyard or community plot shines here during our clear, sunny days. It thrives in well-draining, fertile soil with pH 6.0–7.0. Amend Chico’s often alluvial soils generously with compost or organic matter for best results. Raised beds help with warmth and drainage during intense summer heat. Avoid shady or low-lying cool spots to maximize early production.

Support and Pruning

As an indeterminate variety with energetic vines, Sweetie needs sturdy support—use tall tomato cages, stakes, or a trellis to handle the heavy clusters. Prune suckers selectively to 1–3 main stems for better airflow and higher yields. In Chico’s dry heat, this also reduces disease pressure. Tie vines as they grow to keep heavy fruit clusters off the ground.

Watering and Feeding

Water deeply and consistently (1–2 inches per week), especially during Chico’s 90–100°F+ summer days. Use drip irrigation or soaker hoses to keep foliage dry and prevent issues. Mulch with straw to conserve moisture and cool roots in our Mediterranean climate. Feed every 2–3 weeks with a balanced organic tomato fertilizer or compost tea—Sweetie is a heavy producer that rewards rich feeding. Once established, it handles heat well with steady moisture.

Pest and Disease Management

Sweetie offers good resistance to alternaria stem canker and performs reliably in Northern California conditions. Watch for tomato hornworms, aphids, and occasional early blight. Chico’s dry summers reduce fungal risks compared to humid areas, but maintain good spacing and airflow. Hand-pick pests, use neem oil as needed, and rotate crops yearly. Companion plants like basil or marigolds help deter insects naturally. Remove any diseased material promptly.

Harvest and Flavor Tips

Harvest Sweetie cherries when they’re fully red and firm—usually starting in early to mid-summer in Chico and continuing until the first frost (around mid-November). Pick clusters easily by the handful; the fruits store well. For peak sweetness, let them ripen fully on the vine. Enjoy fresh as snacks, in salads, or halved for roasting—the intense sugary flavor shines with minimal seasoning. One plant can produce gallons of fruit all season long in our extended growing window!

Plant Sweetie this season in Chico for baskets full of irresistibly sweet cherry tomatoes—prolific, delicious, and perfect for our sunny California summers! A must-have for snacking and sharing with the family.
