Troubleshooting
Cranberry 'Stevens' problems — and how to fix them
Cranberry 'Stevens' (Vaccinium macrocarpon 'Stevens') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Drying out
Even brief dryness damages this bog cultivar, wilting runners and fruit. Maintain permanently moist soil, standing pots in water trays through the growing season.
Lime-induced chlorosis
Alkaline water or media yellow the leaves. Use only rainwater and acidic, peat-based compost to hold the required low pH.
Excess runners, light cropping
Over-feeding or shade yields lush runners but few berries. Grow in full sun, feed sparingly and trim surplus runners to favour fruiting uprights.
Fungal fruit rots in stagnant conditions
Though disease-resistant, poor air flow and stagnant water can invite fruit rots. Ensure moving fresh water or periodic refreshing and good light exposure.
