Ideal time to plant bluebonnets is in the fall, especially if planting by seed.
Growing bluebonnets from seed can be challenging due to their tough seed coat and low germination rates. But, scarification to the seeds using sandpaper to roughen the seed coat may help it along.
However, residual seeds remain in the soil for the following year. As the hard seed coats wear down from abrasion and decay, with some water the seedlings begin to sprout.
The hard seed coat is an excellent mechanism for survival during unfavorable years, but it can frustrate the gardener who wants a spring display of colorful blooms the first year after planting.
Soak Bluebonnet seeds in lukewarm water over night before sowing outdoors.
Then sow wildflower seed directly into prepared soil 1/8 inches deep, which is loosened and weed free. Keep the soil moist until germination.
In order to reseed the Blubonnet wildflower, allow the pods form and drop their seeds.
Once Bluebonnets established just sit back and let them be! As long as they have plenty of sun and well-drained soil they are going to thrive.
For a beautiful display, mix them in with perennials to add early spring color before the perennials take off.
If one year bluebonnets are superabundant, there are more seeds still in the soil to germinate for the next year. When it comes to establishing Texas Bluebonnet, the key is you’ll need to be patient.
