Media: Use a well-drained, disease free, peat-based growing mix with pH 6.0-6.2 (no lower) and
EC <1.5mmhos.
Temperatures: Temperatures for rooting out after transplant should be 65-68°F (18-20°C)
Temperatures for growing on can be lowered to 62-65°F (16-18°C)
Light: Light levels should be 3000-5000 f.c. as a guide. HID lights can be used in low light
periods to give more total light and encourage flowering.
Irrigation: Practice a good wet/dry moisture cycle but avoid wilting. Geraniums do not like to be too
wet but can’t tolerate wilt either.
Fertilizer: Feed 1–2 times per week with 150–200 ppm N from 15-5-15, 17-5-17, or 13-2-13, it is
best to use calcium based fertilizers, extra iron can be added if needed. Keep media pH
6.0–6.8, and media EC 1.25–1.75 mmhos, any higher can cause root damage.
Growth Regulators: Quantum is a slower growing, more compact variety than Horizon so less PGR is
required. For toning, use sprays of Cycocel (350-1500 ppm) or B-Nine (800-1500) +
Cycocel (350–1000 ppm) to control growth. Bonzi sprays (2–5 ppm) can also be used
once the foliage covers the media but avoid drenching. It is best to run your own trials to
avoid overdosing, as weather and cultural regimes can affect the requirements
Pests: Aphids, Thrips
Diseases: Pythium, Botrytis, Alternaria Leafspot, Rust. Necrosis on lower leaves is likely to be
caused by media pH <6.0, upper yellow leaves – high media pH >6.8 or low iron.
