Overview

• September signals active work: complete late-winter pruning, weed, aerate and amend soil, apply measured fertilizer, and begin early pest and disease inspections.
• Container advice gets granular with spacing of roughly 20–30 cm for herbaceous crops and pot depths of up to 30 cm for small herbs versus 50 cm or more for larger vegetables.
• Pot material and color matter for moisture and heat management, with plastic holding more water than terracotta and light-colored containers keeping substrates cooler in full sun.
• Quality checks are urged for inputs, including SENASA-registered vegetable substrates with pH about 5.5–6.5, factory-sealed seed packets with dates and scientific names, and compact, healthy seedlings sized by common liter categories.
• Watering is advised at dawn or dusk so plants reach midday well hydrated, with warnings to avoid overwatering and to ensure good aeration as warmer, more humid weather raises fungal risk.
