Growing & Sowing Tips
📅 SowingStart seeds indoors in February-March; move the seedlings outdoors 2 weeks after the last frost.
🌱 Depth0.3-0.5 cm
📏 Spacing20-30 cm
🌞 SunFull sun (5-6+ hours of direct sun a day); it tolerates light afternoon shade, but flowering is highest in full sun.
💧 WateringRegular, especially in hot weather; wilting is the first warning sign
🧺 HarvestFlowers start opening 8-10 weeks after transplanting; regular deadheading gives more flowers
🪴 SoilWell-draining, moderately fertile garden soil; flowering drops in overly nitrogen-rich soil
⭐ DifficultyEasy
🗓️ SeasonSpring/Summer
📅 Calendar is for the Northern Hemisphere; in the Southern Hemisphere shift sowing times by ~6 months.
💡 Key tip: Pinch off faded flowers regularly (deadheading); this practice keeps the plant flowering through the summer and prevents seed set. In the vegetable garden you can scatter petunias among beans, peppers, tomatoes or asparagus to use them as both a pest repellent and a pollinator attractor.
🤝 Companion logic: A good-natured neighbour compatible with most vegetables and herbs. It repels pests such as aphids, leafhoppers, the asparagus beetle, the tomato hornworm, the squash bug and the Mexican bean beetle (thanks to its nightshade alkaloids); its flowers draw bees and beneficial predatory insects. It works especially well with bean, pepper, tomato and asparagus; near squash it can be scattered as a pest repellent/trap. Avoid sowing it right at the base of strong, shading plants like corn, squash and sunflower (competition for light and nutrients).
