Although they are drought tolerant, that doesn't meant drought is a good thing. Regular watering is necessary for optimal performance.

Fertilizer is not necessary, although a little couldn't hurt. Take it easy on the nitrogen in the plants early phases as excess nitrogen could delay flowering. A little organic mulch is a good idea also.

If you are Harvesting Seeds check the blossom heads for maturity. The back side becomes a yellowish brown instead of its youthful green. The smaller petals that were covering the seeds will have dried and begin falling out. Some of the blossom heads may be leaning downwards. When the blossom head in fully mature 'snap' it off and remove and separate the seeds by hand. This can be a tedious task - you can also rub harvested heads together which helps to dislodge seeds.
