One of the most common questions asked by gardeners is, “What are the best plants for desert heat?” The answer is actually quite simple. Geraniums need at least five to six hours of direct sunlight per day to thrive. During their growing season, they can tolerate temperatures as low as 55 degrees Fahrenheit. To ensure a successful transplant, you should plant your geraniums in pots that drain well. You should also choose a spot that receives a minimum of 4-6 hours of direct sunlight daily.

Geraniums can be planted in pots or the ground. Make sure you leave about 10 to 12 inches between each plant. After planting, make sure you remove dead flowers and leaves from your geraniums. They are also susceptible to fungal diseases, and you should avoid over-watering them. Over-watering can result in root rot or edema. In addition, cut off the blooms of geraniums once they begin to fade. Deadheading is another essential aspect of geranium care.

You can grow geraniums in a low-water garden in the San Francisco Bay Area. They will tolerate daytime temperatures in the mid-80s. You can plant them next to Old Roses, bearded iris, and pinks, as they provide shade and help maintain a cool temperature. To prevent evaporation, cover the soil with at least 5 inches of mulch.

If you’d like more flowers, you can also divide them and plant them in groups.
