All potting mixes are not created equal. Your container plantings need soil that holds some moisture but drains well and offers plants a rich supply of nutrients. Purchase a reliable, high-quality commercial potting mix or make your own special blends for various uses.
If you fill containers with garden loam or packaged potting soil, they may be too heavy to move. In addition, the soil tends to become oversaturated when wet, and then dry out and turn rock hard. Add water-absorbing polymer crystals to your potting soil to minimize your watering chores. But remember, container plantings require watering more often than garden plants -- daily in hot, dry weather.
