What are the ecological habits of petunias?

Prefer warm and sunny surroundings. Not resistant to frost and afraid of rain and waterlogging. It grows at a temperature of 13 18 and 4 10 in winter, if it is lower than 4, the plant grows again.

However, in the rainy season, there is a lot of rain, which is very unfavorable to the growth of petunias, the potting soil is too wet, the stems and leaves are easy to grow, the flowering period is rainy, and the flowers are easy to fade or rot.

If the potting soil is waterlogged for a long time, the rotten roots will die, so it is advisable to use loose, fertile and well-drained sandy loam soil for potted petunias.

It is a long-day plant, and the growth period requires sufficient sunlight, and it takes about 100 days from sowing to flowering under normal light conditions. When petunias are cultivated in winter greenhouses, the stems and leaves grow luxuriantly under low temperature and short day conditions, but it is difficult to flower, and when the spring enters the long sunshine, the flower buds quickly differentiate from the top of the stems and leaves.
