Petunias can tolerate relatively harsh conditions and hot climates. They need at least five hours of sunlight every day and flourish in moist soil and conditions of low atmospheric humidity. They are amongst the most beautiful and easiest annual flowers to grow. Petunias are bright and lively, bloom from spring until frost, and scent the air with lovely fragrance. After transferring it to a pot, make sure to keep the soil moist but do not overwater them. Also, make sure the plant pot has a drainage hole in the bottom of the pot
