Yes, I agree, they don't need to be deadheaded ---- but mine is really not "long" enough to require a trim. When it gets a bit longer I will trim it, but right now it's not required. I use Miracle-Gro fertilizer - the one that is a "Bloom-Booster", so the Nitrogen % is lower. Sunlight right now is at a premium - the weather is definitely not as warm as it should be this time of year here in New Jersey. Hopefully June will be a sunnier and warmer month.
