When to plant Sweet Pea Plants

Plant Sweet Pea plants in early spring, as soon as the soil can be worked and the threat of frost has passed. This is typically from March to April in most regions. Choose a sunny location with well-drained soil enriched with compost. Sweet Peas thrive in cool conditions, so early planting ensures they establish before the warmer months. Provide support such as trellises or fences for climbing varieties, and water regularly to promote healthy growth and abundant flowering throughout the season.

How to Plant Sweet Pea Plants

To plant Sweet Pea plants, choose a sunny, well-drained spot enriched with compost. Install supports like trellises for climbing varieties before planting. Sow seeds or transplant seedlings 1 inch deep and 6 inches apart, ensuring rows are spaced 12 inches apart. Water thoroughly after planting and maintain consistent moisture throughout the season. Apply mulch to retain moisture and suppress weeds. Feed with a balanced fertilizer monthly to promote healthy growth and flowering. Regularly deadhead spent blooms to encourage continuous flowering and pinch off tips to promote bushiness. With proper care, Sweet Peas will flourish, filling your garden with their charming fragrance and vibrant colours.

Sweet Pea plants typically take about 8 to 12 weeks from planting to reach maturity and begin flowering.
