SELECTION
Choose geraniums by color and growth habit, either upright or hanging. Pick healthy plants, full & bushy, with visible flower buds.

SOIL
Grow plants in soil that is porous enough to provide good drainage. In the garden, the plant beds should be cultivated, and organic matter added, mixed & leveled before planting. Improve soil by adding composted cow manure, Complete Planting Mix, or peat moss to the top 4-6" of topsoil. Fertilizers such as 10-10-10 or 5-10-5 may be worked into the soil or added as a light top dressing. For potted plants use a good potting soil mix that contains peat and has good drainage.

PLANTING / SITING
Plant geraniums at the same depth they were growing in the original container. Geraniums grow and bear flowers best if sited in full sun, that is, 6 hours a day of direct sunlight. Plant geraniums outside only after danger of frost is past, usually around Memorial Day. Space them about 18" apart.

WATERING
Water when the soil surface is dry and before plants wilt. Potted plants will dry out more quickly than plants in the ground; a product such as Soil Moist can help retain soil moisture in pots. Water in very well when first planting, and maintain moisture after that. Even watering will prevent oedema in leaves.

FEEDING
To maintain good growth apply a soluble fertilizer such as Peters Blossom Booster or Miracle - Gro every 2-3 weeks. A slow release fertilizer such as Osmocote is also good. Follow manufacturers directions.

MAINTENANCE
Geraniums should be dead-headed regularly to promote continued flowering. Grasp the flower stem close to the main stem and snap off entire flower stem. Avoid leaving part stems behind as they can rot and ruin your plant. Use the same method to remove yellow or dead leaves. Keeping the plant clean will not only look better but helps prevent disease and insect infestation.

PEST CONTROL
Inspect plants regularly for pests and diseases. Treat as soon as a problem becomes evident. A systemic insecticide such as Bonide Systemic Granules can help prevent insect problems. Ortho Rose & Flower spray and Bayer Advanced Garden Rose & Flower Insect killer work well for most insect problems. Clean plants have less problems- deadhead and keep weeded.
