The best exposure is full sun in the morning with light afternoon shade. High summer heat can take its toll on these plants. Many common geraniums stop blooming in sizzling weather, a condition known as "heat check. " (They'll resume blooming when cooler weather arrives. Care. Allow soil to dry to some extent between waterings, then water thoroughly. During the winter, water much less, but do not let the roots dry out entirely. Geraniums do best when given a period of dormancy through the winter months, during which they use less water and do not grow much. A. The two most common reasons for geraniums not blooming prolifically are too little light or too much fertilizer. Geraniums are a sun loving plant that need 4-6 hours of full sun a day, or perhaps longer in somewhat filtered light. South and west exposures are usually best. Ivy, zonal, and scented geraniums are great options for hot summer container gardens. Their blooms come in many different colors (except yellow or blue) and they love hot weather. Make sure that they will get morning sun and afternoon shade if possible. Generally, geraniums are happiest with five or six hours of sunlight a day, though this number can be a bit more or a bit less. It is best to plant geraniums in soil that drains well.

Fertilize geraniums every week because the plants require a consistent supply of nutrients to bloom continuously throughout the season. Use an all-purpose, balanced water-soluble fertilizer applied at a rate of 1 tablespoon to 1 gallon of water. Deadhead wilted blooms throughout the season.

The grounds become a marvelous mulch that helps keep in moisture. Note: Be sure to use coffee grounds on full-grown plants only. Geranium seeds have a hard seed coat, and the grounds can inhibit germination.

Simply touch the soil with your finger going down a couple of inches and your geranium should tell you if she is thirsty or not. If it feels dry, it's time to water, if it's still moist, then wait another day or two and re-test. Just make sure you always allow the soil to get dry before watering and you should be fine.

You should deadhead whenever your geranium blooms begin to look brown or weak. To deadhead your geraniums, rather than simply pulling off the top flowers, you need to go a little deeper in the plant and snap the stem below its node or joint, where new growth begins.

One of the most common causes for yellowing leaves is too much moisture or overwatering. Generally, on over-watered plants, the bottom portions of geraniums have yellow leaves. They may also develop pale-looking water spots. Water or air temperature that is too cool can also result in geranium yellow leaves.

To grow perennial geraniums in one of these cooler USDA zones, plant your geraniums in a container that may be moved indoors in mid- to late fall, before the first frost. Geraniums may be brought outdoors again in the early to midspring, when the threat of frost has passed.

A Healthy Watering Schedule Check the soil with a moisture meter every time before watering. If you don't have a moisture meter, try sticking your finger into the soil, 1 inch down. Water the geraniums when the soil is on the dry side. During warm weather, you may need to water more often.

Try some simple strategies to fight scraggly geranium growth. Buy only geranium plants that have three or more branches. Pinch back geraniums when you plant them and deadhead branches after blooms fade. Remove blooms as they fade. Plant geraniums in full sun where they receive six or more hours of sun each day.

Elsewhere, grow them as outdoor annuals or indoor houseplants. While geraniums can withstand cooler temperatures and even light frosts, hard killing freezes -- when temperatures drop below 20 degrees Fahrenheit -- result in freeze damage and possibly death of the geranium.

Excessive moisture is another cause for leggy geraniums. Geraniums should be planted in well-draining soil and should only be watered when the soil is dry to the touch. Overwatering geraniums can result in a stunted, sickly and spindly geranium plant.

Temperature Range for Geraniums Cultivars of the geranium species typically available at garden centers and nurseries grow best in daytime temperatures between 65 to 75 F and nighttime temperatures between 50 to 60 F.

Geraniums as Indoor Potted Plants Before the first frost, carefully dig up your geraniums and pot them in 6”- 8” diameter containers, with lightweight potting soil. Cut the plants back by a third to a half. Water the pots thoroughly. Place the pots in a bright, cool spot.
