Nemesia can bloom all summer, but it depends on various factors such as the specific species or cultivar, growing conditions, and maintenance. I have personally grown Nemesia in my garden, and I have found that with proper care, they can continue to bloom for an extended period.
Firstly, it is important to choose the right species or cultivar of Nemesia that is known for its long blooming period. As mentioned earlier, N. strumosa and N. fruticans are two popular species that can bloom for an extended period. However, there are also specific cultivars within these species that are bred for their long-lasting blooms. It is a good idea to check with your local nursery or garden center to find out which cultivars are best suited for your region.
In terms of growing conditions, Nemesia prefers rich, well-drained soil with a slightly acidic to neutral pH. It is important to provide adequate sunlight for the plants, ideally at least 6 hours of direct sunlight per day. If the plants are grown in too much shade, they may not bloom as profusely or for as long.
Regular watering is crucial for Nemesia, especially during hot summer months. The soil should be kept evenly moist, but not waterlogged. It is a good practice to water the plants deeply, allowing the water to penetrate the root zone, and then let the top few inches of soil dry out before watering again. Avoid overhead watering, as it can lead to fungal diseases.
Deadheading spent flowers is another important task to ensure continuous blooming. By removing the faded blooms, you encourage the plant to produce more flowers. It is best to pinch or cut off the flowers at the base, just above a set of healthy leaves. This not only promotes more blooms but also helps maintain a neat and tidy appearance.
Fertilizing Nemesia can also contribute to prolonged blooming. A balanced, water-soluble fertilizer can be applied every 2-3 weeks during the growing season. Be sure to follow the instructions on the fertilizer packaging for proper dosage and application.
While Nemesia can bloom all summer, it is important to note that individual flowers may not last for an extended period. The plants produce numerous flowers, and as long as the growing conditions are favorable and maintenance tasks are carried out, new blooms will continue to appear throughout the summer months.
Nemesia has the potential to bloom all summer if proper care is provided. By selecting the right species or cultivar, providing adequate sunlight, regular watering, deadheading spent flowers, and fertilizing, you can enjoy a continuous display of colorful blooms in your garden.
