Yes, you can plant out your sweet peas if it is currently between March and May and conditions are mild.
When to Plant Out Sweet Pea Seedlings
According to the reference (08-Jan-2021), the recommended time to move your sweet pea seedlings or plants from indoors or pots into their final outdoor position is:
- During a mild spell between March and May.
Planting out during this period gives your sweet peas the best start as temperatures are rising, and light levels are improving after the winter months.
Why Timing is Important
Planting out too early in midwinter isn't ideal because temperatures and light levels are less favourable for growth. Waiting for the March to May window ensures the plants have a better chance of establishing successfully before the heat of summer arrives.
Sweet Pea Sowing and Planting Timeline
While the question focuses on planting out seedlings, the reference also provides helpful information on when to sow sweet pea seeds:
- For best results: Sow seeds in late October/November or late February/March.
- Direct sowing: Seeds can also be sown directly into the ground in April or May.
| Activity | Recommended Timing | Conditions |
|---|---|---|
| Sowing Seeds | Late October/November | Overwintering |
| Sowing Seeds | Late February/March | Early spring start |
| Sowing Seeds | April or May (direct in ground) | Warmer soil |
| Planting Out | Mild spell between March and May | Improved temperatures |
Key Considerations for Planting Out
- Choose a mild spell: Avoid planting if harsh frosts are still expected.
- Prepare the soil: Sweet peas thrive in fertile, well-drained soil.
- Provide support: Have stakes, netting, or other supports ready for the plants to climb.
By following the guideline to plant out your sweet pea seedlings and plants during a mild spell between March and May, you give your sweet peas the best opportunity for strong growth and abundant blooms.
