How do I grow bluebonnets?
The secret to growing bluebonnets is to act like Mother Nature. Bluebonnets grow best in poor soil that is undisturbed, such as in much of central Texas.
Bluebonnet seeds have a tough outer coat that must be worn away in order for moisture to penetrate. If you purchase “scarified” seeds and broadcast them on top of the ground in October, you will give them the best chance.
(Scarification means scratching, notching or wearing down by mechanical or chemical means, hard seed hulls to promote germination.)
Now all you do is wait. You may not see any flowers the first year as they will not germinate until fall conditions are just right. Once seeds begin to grow, it is very important to let them develop mature seeds before you mow or remove the plants; otherwise you must plant again in the spring.

My clippers and pruners are rusty; what can I do?
If you store tools in the closed position they may retain moisture from the plants you were cutting, causing rust. It is wise to leave them open so they can dry thoroughly. Spray garden tools with WD-40 and wipe them dry after use. You can also keep a bucket of sand with motor oil poured on top. When you plunge tools into this, it not only coats them but keeps them sharp. Then simply hang them to dry and store them open. Remember to always wipe tools well before using to prevent damage to plants.
