Crossandra is a beautiful flowering plant that is commonly found in tropical regions. It is known for its orange, red, and yellow blooms that add a splash of color to gardens and landscapes. If you are interested in growing crossandra, it is important to know the sowing season and seed rate to ensure a successful harvest.
The ideal sowing season for crossandra is during the summer months when the temperature is warm and humid. The seeds require a temperature of around 25-30 °C for germination. In tropical regions, you can sow crossandra seeds throughout the year since the temperature and humidity remain constant.
When it comes to seed rate, it is recommended to sow around 20-25 seeds per square foot. This ensures that the plants have enough space to grow and develop properly. If you are planting in a pot or container, then you can sow around 3-4 seeds per pot.
To sow crossandra seeds, start by preparing the soil. The soil should be moist and well-draining. Mix in some compost or manure to enrich the soil. Take the seeds and sow them at a depth of 1-2 cm in the soil. Water the soil gently and keep it moist but not waterlogged.
Within 1-2 weeks, the seeds should start to germinate, and you will see the seedlings emerge from the soil. Once the seedlings are around 2-3 inches tall, thin them out by removing the weaker ones, leaving only the strongest plants.
Maintain the soil moisture by watering regularly and fertilize with a balanced fertilizer every 2-3 weeks. Crossandra plants require at least 6 hours of sunlight per day, so make sure to place them in a sunny spot in your garden or landscape.
In conclusion, crossandra is a beautiful and easy-to-grow flowering plant that can add color to any landscape or garden. By sowing the seeds during the summer months and following the recommended seed rate, you can ensure a successful harvest of these lovely flowers.
