🌱 WHY WE START 'Promise' SWEET PEA SEEDS IN ROOTRAINERS
Like all sweet peas, 'Promise' develops a deep root system quickly. Rootrainers encourage strong downward root growth and reduce transplant shock when seedlings are planted into the garden.
We start every Sweet Pea Gardens crop in professional Rootrainers and recommend them to gardeners who want stronger plants and more flowers.

Safety: Sweet peas, just like many plants we grow in our gardens, are toxic. Sweet pea seeds and any part of the plant should not be ingested.

Why We Use Rootrainers at Sweet Pea Gardens
Sweet peas develop long roots quickly. Rootrainers encourage deeper root growth and reduce transplant shock when planting into the garden.
These are the trays we use to start our own sweet pea crop each season.
