Tip for growing Helianthus maximilliani

dandy_line(3B (Brainerd, Mn))September 10, 2006

I am posting this following tip I discovered by accident for Helianthus maximilliani. These plants get huge in rich soil and will flop over once they start flowering. Not a pretty sight. Cutting these plants way back-and late in the season will force them to begin flowering when the stems are only 3 feet high. They make for a very nice clump of yellow this way. I discovered this by accident when the county mower cut down some plants I had put in the public boulevard. They were cut down around the 1st of August. This resulted in the very nice display of short flowering stems in September.

Yes-in a way it's like doing what the Buffalo did for 10,000 years-cut them down to ground level. The plant had to combat this by sending up flower stalks in a very short time. It makes sense to cut all large prairie plants down in mid summer.

Depends on what plant, I think. Many (or most)of them will recover, and bloom on shorter, bushier plants. Some of them will not. I've heard this works well on Joe Pye Weed cut back in June. Great tip!
