Geranium flowers are perennials that reach 1 to 2 feet tall with green circular leaves. Geraniums produce flowers from late spring until the first fall frost. The flowers create red, pink, white and orange color spots in the garden. Geraniums with red blossoms attract butterflies and hummingbirds. These subtropical plants last year-round in warm climates but die off when exposed to freezing temperatures in colder climates. Geraniums are used in flower beds, ground covers and floral borders.
Remove grass, weeds, rocks and debris from a site in full to partial sun to reduce competition for soil nutrients and water.
Loosen the soil to the depth of 6 to 8 inches with a shovel. Spread a 1-inch layer of sphagnum peat moss, manure or compost on top of the soil. Mix the soil amendment in to improve drainage and richness of the soil.
Rake the planting area smooth and level. Remove the geranium plant from its small container.
Dig a hole as deep as the root ball with a hand trowel. Plant the geranium no deeper it was in its nursery container to guard against root rot.
Place the seedling in the hole and fill with soil. Firm the soil in around the plant gently so as not to compact the soil or injure the stem. Space the rest of the geranium plants 12 to 24 inches apart.
Mix 2 tbsp. of 20-20-20 or 15-30-15 liquid fertilizer into 1 gallon of water. Pour the mixture on the soil around the plants, but do not get it on the leaves since this will damage the foliage.
