Arbab and Hamad bhai, it's hard to find specie Gerberas nowadays. Most of them are hybrids raised through tissue culture and therefore, if necessary precautions are taken, flower well for two or maximum three years only. After that, they either die or the flower size / number of flowers is drastically reduced. And if care is not taken, they might not last even a year. Specie gerberas last for many years if planted in a proper position but their flowers are not as stunning as the F1 hybrids.

This is a specie Gerbera and as you can see, the flower is no match to F1 hybrids. But it will grow for years if good drainage is ensured.
As per my little experience, most important factor for growing Gerberas successfully is drainage. They should be watered well however there must never be a boggy soil. The water must drain out quickly. Secondly, they need to be protected from scorching heat as well as frost. They do very well in ground as compared to pots as they need a large root space. However, the position needs to be carefully selected. In most areas, a wind protected dappled shade where they get a few hours of direct sunlight everyday is the best location for Gerberas. Avoid using a silty soil and add lots of leaf mould / compost to improve soil texture and drainage. Gerberas normally do not like competition so be generous while allocating root space. Watchout during monsoon as they will die quickly of water logging if the drainage is not good.
Other than the scientific methods, Gerberas should best be multiplied through division before spring. I used to grow specie Gerberas through seeds and they do ok but the hybrids wont grow from seeds. At least I was never successful. Division is the best method in my view. Use a very sharp knife when you are cutting the base and ensure that there is atleast one growing bud in the piece. An anti-fungal powder may be used while disecting.
Any other member with experience of growing Gerberas.... please help.
