For a very long time, perennials have been one of the more popular varieties of flowering plants. One of the biggest advantages of planting perennials in your garden is that they come back every year. Perennials are popular with both beginning gardeners and experienced gardeners because of the rewards reaped for planting them and being able to have beautiful flowers for multiple seasons.

Another benefit of planting perennials is that they are often easy plants to maintain. Usually perennials are quite easy to care for, and don't require too much extra maintenance, usually just some good quality soil, adequate water and plenty of sunshine. They do have some issues that you should be aware of, one of the most serious being that they are more apt to get plagued by insect and disease than annuals, which only live for one season. Because perennials remain planted in the ground and come back year after year means that they are prime targets for various types of problems, even in fall or winter.

In order to prevent disease or infestation, it is best to buy the healthiest looking plants that you can find. Pay close attention to the plants you buy at the nursery or home center, and do not buy any that show visible signs of disease, fungus, or insect infestation. Healthy plants are stronger plants, and therefore are better able to withstand any bacteria that might be in the soil. A healthy plant will be able to fungi or bacteria that would likely kill off a weaker one.

If you can find them, look for disease-resistant varieties of perennial plants. They have been specially bred for resistance to diseases and insects. Through the process of selective breeding, perennial plant breeders have worked hard choose certain plant varieties that able to survive many common garden problems.

Once you plant your perennials, check them daily for any signs of disease of insect infestation. The ideal time to do this is when you are performing your normal plant maintenance, such as weeding or watering them. Make it part of your general plant maintenance routine. Look for plants with wilted leaves, holes or chew marks on the leaves, dark areas on the leaves or flowers, or chew marks or cut marks on the stems. If you notice any problems, use a gardening manual consult a more experienced gardener to figure out the problem. If you diagnose the problem quickly and accurately, you have a better chance of saving the plant.

The method that you use to water your perennials can affect whether they become diseased. Watering from overhead, such as with sprinklers, promotes the water to pool up on the leaves, which can encourage mold or bacteria to spread among the plants. It is preferred that you water at the root, either through drip irrigation or a garden hose. Not only will this keep water from pooling up on the leaves and flowers, but it the water will reach the roots more quickly, where it really needs to be.

Good care for your perennials is not over at the end of the growing season. It is important to continue to care for your plants even after they have stopped flowering. Make sure you prune your perennial plants according to the specifications for the particular variety. While some varieties of perennials need to be trimmed back drastically, others need very little pruning or none at all. It is vital to heed the needs of each of the types of perennials in your garden.
