🌱 Start with fresh seeds: Use fresh celery seeds to ensure good germination. Old seeds may have a low germination rate.
🏠 Start indoors: Sow seeds in growing trays or pots indoors before the last frost. Celery needs warmth to germinate, which may not be available outdoors early in the season.
💧 Maintain constant moisture: Celery requires consistently moist soil to germinate and grow well. Avoid letting the soil dry out between waterings, but also avoid waterlogging.
☀️ Provide adequate light: Place seedlings in a location with direct sunlight or under grow lights for 12-14 hours a day to promote healthy growth.
🌿 Transplant carefully: When seedlings are about 10-15 cm tall and the climate is suitable, transplant them into the garden or large pots. Be sure to space them properly to avoid competition for nutrients.
🌾 Fertilize regularly: Celery is a fast-growing plant that needs constant nutrients. Use a balanced fertilizer to maintain plant health.
🌬️ Protect from wind and extreme heat: Provide partial shade during intense heat and protect plants from strong wind to prevent damage.

One-line summary: Growing celery successfully requires starting with fresh seeds, maintaining moisture, providing adequate light, and protecting plants from heat and wind.
