Sweet pea are known for being relatively easy to grow, with a few special care points to ensure healthy blooming. They require a position with full sun to partial shade and well-drained, fertile soil. A critical care aspect is providing adequate support, such as trellises or netting, for their climbing habit. Additionally, regular deadheading promotes continuous flowering throughout the season. Watering should be consistent, but overwatering must be avoided to prevent root rot.

Sweet pea likes a place that is warm in winters and cool in summers, with sufficient sunlight. It doesn't thrive well in extreme heat and is slightly tolerant of cold conditions. Best growing temperatures are between 5 to 20 ℃. Temperatures above 20 ℃ affect its growth and even cause withering and death. As an annual plant, sweet peas can be planted in almost all zones. Sweet pea does not require much water and is fairly resistant to drought. If you water it regularly, it will grow better.
