- Overwatering is a problem for all plants except those that grow in boggy areas, such as cattails or other marsh plants. Plants that get too much water may develop root rot, a fungal disease that turns the roots, tubers or bulbs into mush. For that reason, you should never locate plants where standing water develops. The water tray underneath container plants should be emptied after each watering to avoid leaving the roots standing in water. On the other hand, some plants will not do well if their soil is allowed to dry out. In general, succulents and plants with succulent leaves can tolerate drought conditions better than other plants.
- Plants that get too much or too little light will not grow well. While this varies by the type of plant, in general, most plants that bloom need at least half a day of sunlight. Plants that have broad, thin leaves require protection from the afternoon sun, as the bright light may scorch the leaves. Most plants that have brightly colored foliage also grow best with some shade, as too much sunlight can fade the colors in the leaves.
- Plants have maintenance needs. Many perennials will not continue to bloom until the spent flowers are removed. Some clumping plants, such as day lilies, will spread rapidly unless they are dug up and separated. Some herbs, such as rosemary, can spread and get out of control unless severely pruned back. Some varieties of bamboo will spread underground unless contained with a barrier. It's important to know and follow closely your plant's exact care requirements.
