Top 10 Mistakes Gardeners Make


There is a saying that one cannot be a good gardener if she (or he) has not killed at least a thousand plants. That said, there must be a large number of great gardeners.

Gardening mistakes can be time consuming and ultimately costly. Correcting some of these mistakes may sound counterintuitive, but understanding and avoiding  very common errors helps create healthier and more attractive lawns and gardens.

Common Mistakes

  1. Overwatering encourages shallow root systems, stresses plants, wastes water and increases their susceptible to disease and pests. Watering every day is one of the largest mistakes. Water deeply, but only once or twice a week. Most plants (including lawns) go dormant during the fall and winter, so they don’t need much or any water.
  2. Too much fertilizer can cause real problems in the landscape. Too much fertilizer may kill beneficial microbes in the soil, actually encourage disease and requires extra water. Especially dangerous are chemical fertilizers which contain lots of salt. Salt kills organisms, and good gardeners know that the micro- and macro-organisms in the soil are important to soil and plant health. Additionally, fertilizer runoff is one of the largest polluters of our streams, waterways and esturaries.
  3. Kill all those bugs. The goal is to get the unwanted pests under control and the good ones encouraged. Using chemical pesticides kills beneficial soil organisms and the insects that keep pests and diseases at bay. Even organic pesticides should be used sparingly. As with fertilizers, pesticides leach into our water systems.
  4. Misdiagnosing a problem. Know thine enemy. Search the internet for answers or use the local master gardener hotline (if there is one in your area) to identify the problem and possible solutions. Contact the local extension service. There are probably a number of master gardeners in your area who would be happy to help you as well. Two good books for plant and garden care are The Vegetable Book, a Texan’s Guide to Gardening, by Dr. Sam Cotner and Doug Welsh’s Texas Garden Almanac.
  5. Non-native or non-adapted plants. Azaleas – yes. Palms – no. There are several great sources for native plants and ones that are adapted to the Gulf Coast region. One source is Earthkind. This site, produced by Texas A&M, provides hundreds of plants that are adapted to the region. Simply choose your region or input your zip code and the website will lead you through the rest. Another valuable site is Lady Bird Johnson Wildflower Center’s Native Plant Database, which will guide you to lists, planting instructions and habits of hundreds of native species.
  6. Right plant but wrong place. Think and plan before planting. Plants that love the sun probably won’t do well in a shady area. Plants that like dry, well-drained soil won’t be happy in a bog garden.
  7. Not preparing soil before planting. Healthy soil = nutrients and beneficial microorganisms = healthy plants. Use good, organic compost. If you are buying from a local compost operation, ask for specifics on the compost. Compost is generally sold by the bag, or by cubic yard. If buying from a big box store, check the labels to see if it discloses anything about the compost. Find A Composter  is a good place to start.
  8. No mulch. Mulch helps the soil retain moisture, keeps soil at a more constant temperature and discourages weeds. As it decomposes, mulch adds nutrients to the soil. A word of caution. Those pretty mulches which are orange or black are probably dyed. The dye is not something to worry about, because it is made from soy-based dyes,.But the source of the mulch is something to worry about, especially if it discloses that it is made from “recycled” wood (mostly from shredded shipping pallets). Many of these pallets contain wood that has been saturated with chromated copper aresenate (CCA), as a preservative. The CCA can leach into the ground. It can also be taken up by the plant into leaves and fruit. If you must use dyed mulch, do not use it on your vegetable garden.
  9. Planting or pruning at the wrong time. Plant and prune trees in the winter when they are dormant. Don’t resod in the winter.Plant spring blooming flowers in the fall. Plant fall blooming flowers in the spring.
  10. Short-term thinking. How big is that little sapling  going to get in five or 10 years? How much space will the one-gallon esperanza need in a couple of seasons? Remember that those little plants being well irrigated by your sprinkler system now may have a lot of trouble watering everyting when the plants get big. Consider installing drip irrigation in your beds. Drip produces no wastage, gets water down into the root systems where it’s needed and reduces your water bill.
