Cultivation Advice 

  • Start Nemesia Strumosa Blue White (KLM) seeds indoors about 8-10 weeks before the last frost date. They prefer cooler temperatures for germination.
  • Once seedlings have developed a few sets of true leaves and the danger of frost has passed, transplant them outdoors. Choose a location with well-draining soil and partial sun.
  • Provide well-draining, fertile soil for optimal growth. Incorporate compost or organic matter to improve soil texture and nutrient content.
  • Sow the seeds in pots or trays filled with a seed-starting mix. Gently press the seeds onto the surface of the soil, as they require light for germination.
  • If transplanting seedlings outdoors, space them around 8-10 inches (20-25 cm) apart to allow for proper growth and airflow.
  • Keep the soil consistently moist, especially during germination and early growth stages. Once established, water when the top inch (2.5 cm) of soil feels dry.
  • Use a balanced, water-soluble fertilizer diluted to half-strength every two weeks during the growing season to promote healthy growth and flowering.
  • Apply a thin layer of mulch around the plants to retain soil moisture and suppress weed growth. Avoid covering the seedlings too deeply.
  • Regularly deadhead spent flowers to encourage continuous blooming. Prune back leggy growth to promote a more compact and bushy habit.
  • Provide some shade during intense heat, especially in warmer climates, to prevent wilting and stress on the plants.
  • Monitor for pests like aphids or spider mites. Use natural remedies or insecticidal soap to address any issues promptly.
  • Harvest flowers for fresh-cut arrangements, as Nemesia Strumosa Blue White (KLM) blooms can complement floral displays.
  • Periodically trim or pinch back the plants to encourage bushier growth and promote more flowering stems.
  • These flowers thrive in cooler temperatures. In hotter regions, provide shade during the hottest parts of the day to prevent stress and wilting.
  • Continuously remove spent flowers to encourage the plant to produce new blooms. This will prolong the flowering period.
  • Avoid over-fertilization, as it may lead to excessive foliage growth instead of promoting flowering. Follow the recommended frequency and dosage.
  • Ensure the mulch layer around the plants is not too thick, as excessive mulch can trap moisture, potentially causing root rot or fungal issues.
  • If your garden is prone to strong winds, stake taller plants or use a supportive structure to prevent them from bending or breaking.
  • Provide adequate protection during frosty conditions. Cover the plants or bring containers indoors to shield them from cold temperatures.
  • These flowers attract pollinators like bees and butterflies, contributing to the health of your garden ecosystem.
  • Regularly check for signs of pests, diseases, or nutrient deficiencies. Early detection allows for prompt intervention and resolution.
  • If growing in containers, ensure proper drainage and choose a container size that accommodates the plant’s root system adequately.
  • If grown in containers, ensure adequate but not excessive watering. Containers can dry out faster than garden beds, so monitor soil moisture regularly.
  • Maintain a consistent feeding schedule with a balanced fertilizer to provide essential nutrients without overfeeding.
  • Consider using natural pest control methods like companion planting, introducing beneficial insects, or using organic pest repellents to manage pests effectively.
  • Regularly harvest fresh blooms for indoor arrangements to enjoy their beauty and fragrance indoors while promoting continuous flowering.
  • Taller varieties may benefit from staking or support to prevent them from bending or breaking under the weight of the flowers.
  • In warmer climates, provide afternoon shade during extreme heat to prevent heat stress and preserve plant health.
