Frequently Asked Questions

What should I do if my Butter King plants get powdery mildew?

Powdery mildew shows up as a white, flour-like coating on Butter King leaves, usually starting mid-season in humid spells. Remove badly affected leaves early, improve airflow by thinning crowded stems, and spray a preventive-ready fungicide labeled for powdery mildew as soon as the first spots appear (follow label directions). Avoid overhead watering so leaf surfaces stay dry, and discard infected plant debris rather than composting it.

How often should I water Butter King during the main growth (about weeks 3–8)?

During active growth, keep soil evenly moist so the top 1–2 inches don’t dry out completely, which typically means watering about 1–2 times per week depending on heat and rainfall. Water deeply at each session to reach the root zone, then let the surface dry slightly before watering again. Inconsistent moisture is a common trigger for stress and poor development, so aim for a steady rhythm rather than frequent light sprinkles.
