Plants Sensitive To Preen

Preen, a selective herbicide marketed to prevent weed growth in your garden, can be problematic for some plants. Certain plants are more sensitive than others, and if preen gets too close, these plants can experience stunted growth or even death.

Plants such as violets, ferns, hydrangeas, and rhododendrons are on the “sensitive” list, and others may be as well. Preen can harm sensitive plants that are not yet established, and the effects can last for years. For example, a young bed of annuals, newly seeded lawn or a collection of blooming bulbs may all be damaged by preen.

It is important to research plants that are sensitive to preen, and to be aware of how the herbicide might impact your garden or landscaping before you use it.

Alternatives To Preen

When it comes to using weed control products, preen is a commonly used brand. However, certain plants cannot tolerate preen’s active ingredient, trifluralin. Fortunately, there are alternative weed control methods available. These include options such as hand weeding, mulching, herbicidal soaps, and vinegar solutions.

While preen may be effective, these alternative methods have their advantages and disadvantages. For instance, hand weeding is laborious but safe for all plants. Mulching can prevent weed growth, but it may not be as effective as preen. Herbicidal soaps and vinegar solutions require multiple applications, but they are safer to use around sensitive plants.

Overall, before using any weed control method, ensure that it will not harm your specific plants.
