Care Instructions
Nasturtiums require bright, direct sunlight for optimal growth. They prefer moderate temperatures and can tolerate a range of humidity levels. Water the plant when the soil partially dries out, and ensure it is not waterlogged. Regularly check for pests and remove any dead or yellowing leaves to keep the plant healthy.Harvest
Tropaeolum majus, commonly known as nasturtium, can be harvested approximately 60 days after planting. The flowers, leaves, and seeds are all edible and can be harvested as needed. Flowers should be picked when fully open, leaves can be harvested when they are young and tender, and seeds can be collected when they are mature but still green. It is best to harvest in the morning after the dew has dried but before the heat of the day. Regular harvesting encourages more growth and flowering.Soil
Nasturtiums prefer well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil is not too rich in nutrients, as this can lead to excessive leaf growth at the expense of flowers. Adding some sand to the soil mix can improve drainage.Fertilizer
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize sparingly, as too much fertilizer can reduce flowering. Apply fertilizer once a month during the growing season for best results.Repotting
Repotting is generally not necessary for nasturtiums, as they are annuals. However, if growing indoors or in containers, repotting may be needed if the plant outgrows its pot. Choose a slightly larger pot with good drainage and fresh soil.Propagation
Nasturtiums can be easily propagated from seeds. Sow seeds directly in the garden or in containers after the last frost. Plant seeds about 1/2 inch deep and keep the soil moist until germination, which usually occurs within 7-10 days.Pruning
Pruning is not strictly necessary but can help maintain the plant's shape and encourage more blooms. Remove spent flowers and any dead or yellowing leaves regularly. Pinching back the tips of the plant can also promote bushier growth.Toxicity
Nasturtiums are not toxic to pets or humans. In fact, both the flowers and leaves are edible and can be used in salads and other dishes. They have a peppery taste similar to watercress.Additional
Nasturtiums can also act as a companion plant in the garden, helping to repel pests such as aphids and whiteflies. They can be planted near vegetables to provide natural pest control. Additionally, their bright flowers attract pollinators like bees and butterflies.REVOLUTIONIZE YOUR PLANT CARE
