Martha Washington geraniums, also known as Regal or Lady Washington geraniums, have specific preferences when it comes to sunlight exposure. While they do enjoy bright light, it is important to protect them from hot, direct sunlight, as this can cause the petals to fade.
If you are growing Martha Washington geraniums outdoors, it is best to place them in a location where they will receive bright morning sun. This gentle sunlight helps promote healthy growth and blooming. However, it is crucial to ensure that the plants are protected from the intense heat of the afternoon sun. This can be achieved by providing some shade during the hottest parts of the day, such as through the use of a shade cloth or by placing them in a spot where they receive dappled sunlight.
When it comes to soil, Martha Washington geraniums prefer a rich and well-drained growing medium. It is essential to provide them with soil that is slightly acidic, with a pH level ranging from 5.8 to 6.5. This can be achieved by amending the soil with organic matter, such as compost or well-rotted manure, to improve both fertility and drainage.
In my personal experience, I have found that Martha Washington geraniums thrive when grown in containers. This allows me to easily control their exposure to sunlight by moving them around as needed. I have placed them on a covered porch where they receive bright morning sun, but are shielded from the harsh afternoon rays. This strategy has resulted in vibrant and healthy plants with abundant blooms.
To summarize, while Martha Washington geraniums enjoy bright light, it is important to protect them from hot, direct sunlight. Placing them where they receive bright morning sun but are shielded from the intense afternoon rays will help maintain the color and vitality of their petals. Additionally, providing them with rich, well-drained soil that is slightly acidic will ensure optimal growth and flowering.
