General Care Instructions
Sunlight Requirements
Full sun (6-8 hours minimum). In very hot climates, light afternoon shade may be beneficial.
Watering Needs
Consistent moisture is critical, especially during fruit development. Provide 1-2 inches of water weekly, adjusted for rainfall and temperature.
Temperature Range
Prefers temperatures between 65-85°F (18-29°C). Growth slows below 55°F (13°C) and may be damaged by frost.
Fertilizer Requirements
Apply balanced fertilizer at planting time. Once flowering begins, switch to a phosphorus-rich fertilizer to encourage fruit production.
Harvesting
Harvest in approximately 85 days from planting. Pick regularly to encourage continued production. For tomatoes, harvest when fruits are firm and fully colored; for cucumbers, harvest when they reach 2-4 inches for pickling varieties.
