- Warm Climates (Mild Winters): Sweet peas can be directly sown outdoors in late fall or early spring in warmer regions. In areas with mild winters, fall planting allows for strong root development, leading to early and vigorous spring blooms.
B. How to Plant Sweet Peas
1. Growing Sweet Peas from Seed
Sweet pea seeds have a harsh outer coat, which can slow down germination. To improve seed sprouting, try these methods:
- Soaking Seeds Overnight – Before planting, soak the seeds for 12 to 24 hours in a bowl of lukewarm water. This accelerates germination and softens the seed coat.
- Scarification Method – Use a nail file or a small knife to gently nick the seed coat, helping moisture penetrate and encouraging faster sprouting.
In well-prepared soil or seed trays, the seeds should be sown ½ to 1 inch deep. The soil should be kept moist but not soggy until the seedlings appear.

Sweet peas can be sensitive to extreme temperatures, and temperature stress can cause them to bloom prematurely or even decline early. To keep your plants healthy and productive:
- Provide Shade During Hot Weather: In areas where summers are scorching, give your sweet peas some afternoon shade to prevent heat stress. You can plant them in places that protect them from the harsh noon heat or use shade fabric.
- Cool Soil: Sweet peas prefer cooler soil temperatures. Organic mulching around the base of the plants can aid in controlling the temperature of the soil, keeping the roots cooler during hot weather.
- Watering: To reduce stress, keep the soil consistently moist but not soggy. Water deeply during the early morning hours to avoid the heat of midday.
Incorporating these practices into your routine will encourage your sweet peas to bloom longer, giving you a stunning display of flowers that lasts well into the growing season!
