What you need to know to Plant & Grow
Climbing sweet peas thrive in cool spring temperatures and perform best when direct-sown early into deep, fertile soil.
-
Seed Preparation: Soak seeds overnight in room-temperature water prior to planting to soften the tough outer seed coat and encourage faster, uniform germination.
-
Outdoor Direct Sowing: Direct sow pre-soaked seeds outdoors in April and early May as soon as the soil becomes workable in spring. Sow seeds 12 mm deep and 5 cm apart. Germination typically takes 15 to 20 days in cool soil.
-
Thinning & Support: When seedlings reach 7.5 cm in height, thin them to 10 cm apart. Provide a sturdy trellis, netting, or fence for the self-twining vines to climb.
-
Garden Care & Feeding: Keep plants consistently watered throughout the season and feed regularly with a water-soluble fertilizer (such as 20-20-20 or 15-30-15).
-
Summer Performance Note: Flowering may naturally slow during peak mid-summer heat, but plants will resume prolific bloom production with the return of cooler, moderate late-summer temperatures.
