Texas Bluebonnet flowers thrive in warm weather areas in the southern part of the country. The best time to sow seeds is in the mid to late fall. They germinate and grow over the winter months. Germination can be difficult and slow. And, the seeds may not sprout at the same time. Sow the seeds 1/8″ to 1/4″ deep. For large, mass plantings, broadcast-spread the seeds. Then, lightly rake them into the soil.
They can be directly seeded into your flower garden or started indoors for transplanting later. In Texas, they are planted in late fall and over-wintered. In more northerly, areas they are best started indoors or after the last frost date.
Garden Tip: For faster and more successful germination, soak seeds for 72 hours before planting.
Also, for indoor starts, we recommend using a heated germination mat, to increase the speed of germination. And, it, results in a higher germination rate.
Final Plant Spacing: Space plants 12 – 18 inches apart.
Days to Germination: Seeds sprout in 7 – 14 days.

The plants are excellent reseeders. So, select a location where they can grow undisturbed for many ears.
Mix in some compost into the planting site. After planting, apply a balanced fertilizer. Then, water the planting site.
In poor soils, apply a general-purpose fertilizer every four to six weeks during the growing season. In average to rich soils, you do not need to add fertilizer during the season.
The plants are drought tolerant. It’s one of the reasons why Texas Bluebonnet plants are excellent wildflowers. Allow the soil to dry between watering. Most likely, you will only need to water the plant during extended periods of hot and dry weather.
Keep the area well-weeded when the plants are young, so they do not need to compete with weeds for soil moisture and nutrients.
If you grow them in flower gardens, apply a two to three -inch layer of mulch around the plants. This creates a neat and tidy appearance. And, it helps to retain soil moisture.
