Geranium Master Idols

This series of zonal geraniums produces vigorous, heat-tolerant plants. Its multiple large flowers and good branching habit make the six-colored series ideal for use in patio pots or in the landscape. Production in gallons is recommended. Master Idols come in Red, Scarlet Red, White, Pink, Neon Purple and Coral.

Production:

• For unrooted cuttings, unpack and stick them as soon as possible. Stick one cutting per cell and avoid overlapping leaves. If space permits, cuttings may be stuck directly in finishing container.
• Mist enough to keep leaves turgid, but avoid excess leaf wetness to prevent disease.
• Keep temperature at 68-72°F during rooting. Light shade may be required on bright, sunny days.
• Enhance root growth by using 100 to 150 ppm N from a nitrate-based fertilizer after roots appear.
• For rooted cutting liners, unpack immediately and plant as soon as possible. When planting, liner mix surface should be just below the level of growing mix in the finished container. Water if necessary.
• Use a well-drained growing mix with sufficient moisture retention. Avoid iron and manganese toxicity by maintaining a pH level of 6-6.5.
• Thoroughly moisten the growing mix during irrigations, allowing it to dry slightly in between. Reduce the chance of disease by avoiding wet foliage at night.
• Fertilize with a 200 to 250 ppm N fertigation from a complete N-P-K water-soluble fertilizer. The majority of N should be in nitrate form. Avoid fertilizers with high iron and manganese content.
• Keep EC at 2-2.5 mS/cm (SME).
• Master Idols need moderate to bright light intensity. Keep an eye on overhead crops to ensure they’re not causing excess shading.
• Keep day temperature at 70-75°F and night temperature at 65-68°F for three to four weeks to establish crops. Once established, maintain night temperature at 62-65°F for normal production.
