  • water dropWater

    For sweet peas, it's vital to maintain consistently moist soil, especially during their active growth and flowering period. They should be watered deeply when the top inch of soil feels dry to the touch, which could mean providing about 1 gallon per week, depending on weather conditions. However, take care not to overwater, as this can lead to root rot. During hot spells, watering may be needed more frequently, but always test the soil moisture before adding water. It's best to water early in the morning to allow foliage to dry out during the day, which helps prevent disease.

  • sunLight

    Sweet peas thrive in full sun, where they can receive at least 6 hours of direct sunlight every day. The ideal spot for planting sweet peas would be an area with ample morning light and some protection from intense afternoon sun, as too much heat can reduce flowering. Ensure the planting site has good air circulation to promote healthy growth and prevent diseases.

  • thermometerTemperature

    Sweet peas prefer cooler temperatures and will flourish when daytime temperatures are around 60 to 75 degrees Fahrenheit, with nighttime temperatures ideally between 50 and 65 degrees Fahrenheit. They can withstand a light frost and should be planted in early spring. The maximum temperature for sweet peas should not exceed 80 degrees Fahrenheit, and the minimum should remain above freezing to prevent harm to the plants.

  • scissorsPruning

    Pruning sweet peas encourages bushier growth and more abundant blooms. Regularly deadhead spent flowers, removing them just above a set of leaves to prompt further flowering. Around midseason, you can cut back the stems by about one-third to rejuvenate the plants. The best time for significant pruning is when the plant begins to look tired or after a flush of blooms has finished.

  • bambooSoil

    Sweet Pea 'Brook Hall' thrives in rich, well-draining soil with a pH between 6.0 and 7.5. To create the best soil mix, combine two parts loam, one part well-rotted manure or compost, and one part sharp sand to ensure good drainage. Regular addition of organic matter will help in nutrient retention and structure improvement.

  • plantRepotting

    Sweet Peas like 'Brook Hall' are typically annuals and thus do not require repotting. They are sown directly where they are to flower and do not thrive well with transplanting due to their delicate root systems. They are best sown in new pots each season if not sown directly in the ground.

  • water dropsHumidity & Misting

    Sweet Pea 'Brook Hall' prefers moderate humidity conditions, similar to what is commonly found outdoors in their growing season. They do not require exceptionally high humidity, but it's important to ensure the air isn't too dry, particularly if grown indoors which can be mitigated by occasional misting.

  • circleLife cycle

    Sweet pea 'Brook Hall' begins its life cycle when seeds are sown into well-drained soil, typically in late winter or early spring. After germination, the seedlings rapidly develop a root system and shoot, and will soon produce climbing tendrils that require support, as Sweet peas are climbing plants. The vegetative stage is characterized by the growth of stems and leaves, and this stage can last for several weeks as the plant gains height and strength. As temperatures increase in late spring or early summer, the plant enters the flowering stage, producing fragrant, colorful flowers abundantly, which can attract pollinators like bees and butterflies. Following pollination, the flowers will produce pods containing seeds, thus reaching the reproductive stage. These seeds mature, are harvested or fall to the ground, and then enter a period of dormancy until the next growing season when the cycle can begin anew.

      Spring-Early Summer

    • Sweet pea 'Brook Hall' is typically propagated through seeds. The optimal time for sowing these seeds is either in late winter, around February to March, or in autumn, around October to November for areas with milder climates. To propagate them, first you need to soften the hard seed coat to encourage germination. This can be done by soaking the seeds in water for 24 hours or by gently nicking the coat with a file. Then plant the seeds about 1 inch deep (2.54 centimeters) in pots filled with a well-draining seed starting mix. Place the pots in a bright area and keep the soil moist. Germination usually occurs within 10 to 21 days. Once seedlings have grown strong enough and the risk of frost has passed, they can be transplanted outdoors into their final positions. It's important to provide support for the climbing vines as they grow.
