A grower with a healthy N. hamata in overgrown live sphagnum (strands hanging 5–6") sees red spots on older leaves. Asks if Ortho systemic spray will harm the moss.
No treatment needed unless you see actual fungal patches or insects.
Can kill sphagnum if sprayed heavily. Concentrate spray on plant, avoid moss. But with a healthy plant and no pests, don't spray at all.
Enjoy the beautiful hamata—it's thriving.
