Petunias For Fall

petunia-market-packspetunia-mass

This is the season that petunias thrive just like in spring. They are appearing in garden centers and big box home improvement stores now. Go ahead and plant them as soon as you purchase, even though we are very dry, if you can keep them watered. Remember they will bloom and grow only until our first frost. I like to make sure mine are planted in well broken up soil and planted at the level that they come out of the pots. Water well. Use the three time rule when planting; in other words, water each plant three times at planting. After a couple of weeks in the ground, fertilize with a basic liquid feed and then another time in mid-October. Since petunias this time of the year are mostly prostrate, I like to mulch the plant with pine straw, and this will keep the plants from rotting on wet ground. The key to constant bloom is pinching off the spent blooms. Each year petunia displays are more and more popular, with good reason. They are striking.
