Do geraniums do well in Arizona heat?

Although classified as a perennial, geraniums are usually grown as annuals to be enjoyed for several months in the spring and fall. They can be kept during the summer, but our intense desert heat usually renders plants weak and flowerless until the arrival of cooler weather in the fall.

Can geraniums tolerate extreme heat?

Geraniums have always been known to tolerate heat better than most plant species, but the recent development of hybrid geraniums has meant varieties that can take on tough climates like Texas and Arizona, where 100-plus-degree summers are the norm.

Do geraniums like hot sun?

Most annual geraniums need a spot in full sun, except for the ivy geranium, which grows best in light shade. Perennial geraniums, on the other hand, grow in either sun or shade, depending on the type.

How often should I water my geraniums in Phoenix?

Be sure to water your Geraniums thoroughly, but allow the soil time to dry (equivalent to a damp sponge) in between watering. Use a well-draining soil, like SummerWinds Potting Soil, to ensure proper moisture. Yellowing leaves indicates that you may be watering too frequently.

Can geraniums get too much sun?

Geranium plants should receive around four to six hours of direct sunlight every day, and more if the light is filtered. However, they can survive in less sunny conditions.

When should I bring geraniums inside?

Article content. To overwinter geraniums, bring them indoors prior to frost. If you are growing them in a tub or container and time is at a premium (as it usually is in fall), simply drag the entire pot indoors where they should keep for a few weeks while you tend to other more pressing garden chores.

What temp can geraniums handle?

During winter, geraniums grow best with night temperatures of 50° to 60°F (10° to 16°C) but will survive if they drop to 32°F (0°C) and/or rise above 80°F (27°C), as long as they are kept relatively dry.

Do geraniums melt in hot weather?

With the introduction of interspecifics, there has been a shift in how geraniums perform. Our historic data shows that almost all varieties tested melted the first day we hit 100°F. They definitely melted if we had nights over 85°F. But recently, we have seen a number of interspecific hybrid geraniums introduced.

Can you grow Geraniums in Arizona?

Arizona Cooperative Extension, Yavapai County. Geraniums (Pelargonium sp.) are one of the most popular flowering plants. They are grown as bedding plants, perform well as both bedding plants and potted plants, and can be easily as house plants if given a sunny location.

What are the best hybrid geraniums for high temperatures?

But recently, we have seen a number of interspecific hybrid geraniums introduced. They have been not only able to tolerate our high day and night temperatures, but they survive longer into the season. The Caliente and Calliope series, both from Syngenta Flowers, have been two of our best performers for the last four seasons.

Are your geraniums having trouble in the Texas summer?

Jenny Wegley, research and greenhouse manager at the Dallas Arboretum and Botanical Garden in Dallas, Texas, shares geranium highlights at the arboretum from this past summer. We have had trouble in the past with geraniums not being able to tolerate the heat and drought conditions of our summers.
