Spring Growth (Year 2)
8-10 weeksBasal leaves expand; stems elongate rapidly; plant reaches 1-2 feet by early summer
Continue weeding. Thin crowded growth if necessary. Provide supplemental water during drought. Stake if plants become lanky.
Flowering
6-8 weeks (late August to October)Dense pyramidal flower clusters form at stem tips, golden-yellow color intensifies; plants 2-4 feet tall
Deadhead spent flowers to encourage continued blooming. Avoid excessive nitrogen which promotes foliage over flowers. Monitor for powdery mildew.
