How To Control Water Hyacinthwater hyacinth

There are some weeds that actually start out as desired plants and are planted because of their beauty, however, planters and pond owners are quickly filled with regret after planting the weed and seeing it multiply and take over. This is especially the case with the aquatic weed, water hyacinth. In a perfect world, only a few of these plants in the water would be pleasant, but water hyacinth doesn’t work that way, preferring to completely cover a pond with it’s spread. If left unchecked, water hyacinth can dominate an entire body of water.

Water hyacinth is a free-floating aquatic weed found either on the surface of fresh waters or anchored in mud. Water hyacinth it’s known for its wide fleshy green leaves and pretty-looking purple flower. Plant size ranges from a few inches to a meter in height. Water hyacinth is a very prolific plant with it’s potential to spread being extremely rapid resulting in sizable infestations over large areas of water causing a variety of problems.

Water hyacinth can grow in mats up to 2 meters thick which can reduce light and oxygen in waters, affecting water chemistry and causing a significant increase in water loss due to evapotranspiration. It also causes transportation and recreational problems, hampering activities such as boating, fishing and swimming.

How To Get Rid of Water Hyacinth: 3 Step Solution

Removing water hyacinth is no easy feat, but it’s not impossible.  There are several ways you can go about removal. Some take the manual route and physically remove the weeds via raking or skimming them off the water surface. However if you have a particularly large water hyacinth problem where they have heavily overtaken your pond or lake, physical control may be too labor intensive, costly and time consuming to carry out. At Solutions Pest and Lawn we have aquatic herbicides which you can use to kill off water hyacinth and discourage growth. Below we have laid out a 3 step plan where if followed closely, you can easily eliminate water hyacinth.

Step 1: All chemical control treatments should start with a careful inspection. Survey your lake or pond and determine what the best and safest plan of option there is to take. You have to take into account how the lake or pond is utilized not only by humans but also the fishes and aquatic life which inhabits the water. Asking yourself these questions and weighing the pros and cons of control before proceeding is a highly recommended first step in making sure that you do not affect the vegetation and communities which live within the water or contaminate the water where it’s not safe to swim in or drink.

Step 2: Once you have carefully analyzed your pond and lake, you can then move on to selecting a treatment method to manage the water hyacinth. At Solutions Pest and Lawn, we have a large selection of different aquatic herbicides which come in both liquid or granular forms. Liquid herbicides are a great solution because they attack weed growth in shallow water on or above the ponds surface and can be spread evenly with a pump sprayer. This makes the control process efficient and convenient to physical removal.

Granular herbicides are also an excellent selection especially when weeds are submerged as blankets under the water surface in deep areas of the pond or in ponds with flowing water. These heavier granules can be applied with a hand spreader and will sink directly onto the weed beds. What you select is entirely up to your personal preference. You will see our recommendations below.

Step 3: Apply the selected herbicide to your pond or lake during ideal temperatures and following the instructions carefully on the product label of the herbicide you chose. Depending on the size of your pond or lake, you may need to conduct treatment in sections, waiting 2 weeks between treatments until you’ve treated the entire body of water. To prevent water hyacinth from returning, make sure to control the nutrient levels in your pond. There is a more
