Nicotiana, also known as flowering tobacco, is a genus of plants that are prized for their beautiful and fragrant flowers. These plants are relatively easy to grow from seed, making them a great option for both experienced and novice gardeners. In this comprehensive guide, we will provide you with all the information you need to know on how to sow nicotiana seeds successfully.

When to Sow Nicotiana Seeds

The best time to sow nicotiana seeds depends on your climate. In general, seeds can be sown indoors 6-8 weeks before the last frost date. If you are sowing seeds directly outdoors, wait until the soil has warmed to at least 60°F (16°C).

Choosing the Right Seeds

There are many different varieties of nicotiana available, so it is important to choose the ones that are best suited to your climate and growing conditions. Some popular varieties include:

• Nicotiana alata: This is the most common type of nicotiana, and it is known for its large, trumpet-shaped flowers.
• Nicotiana sylvestris: This variety has smaller flowers than N. alata, but it is more fragrant.
• Nicotiana langsdorffii: This variety is native to South America, and it has large, showy flowers that are often used in cut flower arrangements.

Preparing the Soil

Nicotiana plants prefer well-drained soil that is rich in organic matter. Before sowing the seeds, prepare the soil by tilling it to a depth of 12-18 inches (30-45 cm) and adding compost or other organic matter.

Sowing the Seeds

Nicotiana seeds are very small, so it is important to sow them carefully. Sow the seeds on the surface of the soil and gently press them into the soil. Do not cover the seeds, as they need light to germinate.

Watering the Seeds

After sowing the seeds, water them gently. Keep the soil moist but not soggy.

Germination

Nicotiana seeds typically germinate within 10-14 days. Once the seedlings have emerged, thin them out so that they are spaced 6-12 inches (15-30 cm) apart.

Transplanting the Seedlings

When the seedlings are 3-4 inches (7-10 cm) tall, they can be transplanted outdoors. Choose a sunny location with well-drained soil. Dig a hole that is twice as wide as the root ball of the seedling and plant the seedling at the same depth as it was growing in the seed tray.

Caring for Nicotiana Plants

Nicotiana plants are relatively easy to care for. They require regular watering, especially during hot weather. Fertilize the plants monthly with a balanced fertilizer. Deadhead the spent flowers to encourage new blooms.

Troubleshooting

Nicotiana plants are susceptible to a few pests and diseases. Common problems include:

• Aphids: These small insects can suck the sap from nicotiana plants, causing the leaves to turn yellow and wilt.
• Whiteflies: These small, white insects can also suck the sap from nicotiana plants.
• Botrytis: This fungal disease can cause the leaves and flowers of nicotiana plants to turn brown and rot.
