How to control Tropical Spiderwort?

Do you want to control the tropical Spiderwort? There are several options to regain control of your growing space. For those with small gardens, tropical spider grass can be controlled manually. This should be done by removing the weeds as soon as they come out of the ground. Not only does this make it easier to remove the plant, but it also ensures that it doesn’t have a chance to multiply. Because of their ability to spread underground, removing mature comfrey plants can be extremely difficult. 

Implementing intensive planting can also help control the presence of tropical spider plants. Fast-growing plants can better shade the ground if you reduce plant spacing. Without sunlight, tropical spider plants of different types can have trouble establishing themselves in planting. Tropical spiderweeds in large plantations can be more difficult to control. 

In these cases, manual control is usually not a realistic option. Commercial growers can use the pre-emergence method with some success.
