Planting Dates - September 15 thru November 15. Bluebonnets typically have a hard seed coat and/or a certain percentage of dormancy associated with the germination. By planting in the fall, the seed is able to over-winter in the soil and result in a larger number of seed germinating in the spring.
Seeding Rates - 1 lb/2,000 ft² or approx. 22 lbs/acre. Rates are fairly arbitrary, as bluebonnets will usually increase in numbers through the years, if conditions are appropriate. For more flowers the first year, use a heavier rate. For a thinner stand the first year, with the intent of letting the plants propagate and become more numerous, use a lower rate.
Site Selection - Select a site that has good drainage in mostly to full sun.
Care and Maintenance - For best results, keep the area moist (not over-watered) for 4-6 weeks during the growth period. If mowing is desired once the bluebonnets are established, mow at a height of 4-6 inches only after the seed has set and flowers are brown and drying.
