How many years can petunia live?

1. Survival time

Under normal circumstances, it can survive for one to two years. However, due to different planting methods, growth environment, cultivation methods and other conditions, the survival time of petunias is often different. Some only live for a few months before dying; some live longer, up to a year; some can live for two years; and some can live for four to five years, or even longer. In fact, as long as you master the various planting conditions, you can extend the survival time of petunias. If the temperature, light, water, fertilizer, pruning, etc. can be reasonably controlled, the survival time of petunias will be greatly extended, and they can survive for one or two years or even longer. However, if it lives too long, its parts will age and the plant will become unhealthy, drying up and weakening. Moreover, the number of flowers that bloom will become fewer and fewer, and eventually there will be no flowers at all. So, generally speaking, petunias only need to be grown for one or two years. When it blooms, you can collect its seeds and prepare for the next round of planting.

2. Precautions

1. Pay attention to daily pruning and fertilizing.

2. Make adequate preparations for the wintering of petunias to ensure they can overwinter safely. It needs to be placed indoors in winter, and when the temperature is below four degrees, it will grow very slowly. It's almost stagnant, so pay attention to the temperature.

3. Provide plenty of sunlight and good ventilation conditions.

4. If you only raise it for one year, you should "pinch" the seedlings during the seedling stage. After two or three times of "pinching", the petunia will bloom and fill the pot.
