  • water dropWater

    Sweet peas, including 'Jacqueline Heather', prefer to be watered deeply and infrequently, allowing the soil to dry out slightly between waterings. Generally, aim to water once a week with about 1 to 1.5 gallons of water per plant, depending on weather conditions. During hot or windy weather, they may require more frequent watering, but be cautious as overwatering can lead to root rot. It's important to water at the base of the plant to keep the foliage dry and reduce the risk of fungal diseases.

  • sunLight

    Sweet peas like 'Jacqueline Heather' thrive in full sun, where they receive at least 6 to 8 hours of direct sunlight daily. The best spot for them is in a well-lit area that gets morning sunlight and some afternoon shade, particularly in hot climates to prevent the blooms from fading quickly.

  • thermometerTemperature

    Sweet peas, including 'Jacqueline Heather', perform best in cool to moderate temperatures, ideally between 55°F and 65°F. They can tolerate a minimum temperature of about 40°F and a maximum of around 75°F, but prolonged exposure outside this range can hinder growth and flowering.

  • scissorsPruning

    Sweet peas, including the variety 'Jacqueline Heather', should be pruned to encourage bushier growth and more blooms. Pinch out the tips when the plants are about 4-6 inches tall. Deadheading spent flowers regularly will also promote continuous blooming. The best time for pruning is when the plant has produced several pairs of true leaves.

  • circleLife cycle

    Sweet pea 'Jacqueline Heather' begins its life cycle when the seed is sown into well-draining soil, ideally in early spring or late autumn. Germination occurs within 7 to 15 days, after which the seedling emerges, growing its first true leaves and developing a root system. As it transitions into the vegetative stage, the plant grows rapidly, producing climbing stems and characteristic pinnate leaves that require support such as a trellis. Flower buds develop as the plant matures, leading to a blooming phase where fragrant, purple-pink flowers are produced, particularly abundant in cool, temperate conditions. Following pollination, typically facilitated by bees and other insects, the plant sets seed pods, and once the seeds are mature, they can be harvested for subsequent planting. In the final stage, the plant begins to senesce and will eventually die back, especially if exposed to frost, completing its annual life cycle.

  • sproutPropogation

    • Propogation time


    • Propogation: The Sweet Pea 'Jacqueline Heather' can be propagated effectively by sowing seeds, and the ideal time to start this process is in late winter to early spring. The most popular method to propagate Sweet Pea 'Jacqueline Heather' is through seed propagation. To do this, soak the seeds in water for 24 hours to soften the hard outer shell, which can speed up germination. After soaking, plant the seeds about 1 inch (2.54 centimeters) deep in pots or trays filled with moist potting soil. Keep the soil temperature around 55 to 65 degrees Fahrenheit (13 to 18 degrees Celsius) for optimal germination, which typically occurs in 10 to 21 days. Once the seedlings have developed a few sets of true leaves, they can be hardened off and transplanted outdoors after the danger of frost has passed. It's important to plant them in a location that receives full sun to partial shade and has well-draining soil to promote healthy growth.
