How to Plant & Grow Geraniums


Tufts of colorful bloom heads on sturdy stalks surrounded by wavy, vivid green foliage are the hallmarks of geraniums. Pelargonium genus geraniums include the commonly planted annual zonal varieties and are the most readily available at garden centers. Blooming in colors from red, coral, salmon, pinks and whites, geraniums can be grown outdoors or indoors, depending on the variety and your climate.

Step 1

Choose a bedding location in full sun with well drained soil or a pot with drainage holes. Pots as large as 12 inches across will provide adequate room for a large root system.

Step 2

Cultivate beds with organic compost, such as pine bark, to a depth of 6 inches to improve drainage. Create a potting mix for containers of equal parts garden soil, peat moss and perlite for best results.

Step 3

Incorporate a 10-20-10 rate fertilizer according to manufacturer directions at the time of planting in beds or in containers.

Step 4

Plant geraniums up to 1 foot apart in beds and one per pot for 12-inch diameter pots.

Step 5

Cover the planting bed with several inches of organic mulch, such as pine needles, to maintain moisture and deter weeds.

Step 6

Water geranium beds well to maintain soil moisture, but do not allow roots to sit in puddles. Allow excess water to drain through holes in containers, and avoid using a tray, which may encourage rot or disease spread.

Step 7

Apply additional liquid fertilizer every four weeks to improve growth and flowering volume.
