Gerberas: Not Too Much Sun
Although Gerberas must have sunshine you will need to offer them protection against the rays from the harsher afternoon sun. This is why so many people have difficulty establishing these plants in the outdoor garden setting. Choose a prime location for these plants that lets them receive the morning sun and provides some shelter during the afternoon. An east facing location will be ideal. Some people also discover that growing Gerberas in front of some taller plants will provide them with the shade they need during the afternoon.
Growing gerberas can be a little tricky sometime, but is definitely worth it.
