Soaking Sweet Pea seeds in water overnight before planting can help soften their hard outer seed coat and support water absorption. Some gardeners also lightly nick the seed coat to encourage germination. Avoid soaking seeds that are already swollen or damaged, and discard seeds that become soft or show signs of decay.
Climbing varieties of Lathyrus odoratus commonly reach approximately 5–8 feet, although the mature height depends on the cultivar and growing conditions. Some dwarf and bush varieties remain much shorter. Provide a suitable trellis, garden netting, or fence for climbing varieties.
Keep Sweet Pea plants adequately watered, provide suitable sunlight, and remove faded flowers regularly before seed pods develop. Harvesting flowers frequently can also encourage continued blooming. Sweet Peas prefer cooler growing conditions, and flowering may decrease during periods of excessive heat.
