The return of spring is celebrated for many reasons, but with warmer weather comes the reawakening of nature — including unwanted weeds. Planning for the emergence of spring vegetation is perhaps the most important part of land management. Having a strong understanding of plant life cycles and various control methods is necessary to develop an effective integrated vegetation management plan.
In general, there are three types of life cycles for weeds: annual, biennial or perennial. The best way to treat and control unwanted weeds is dependent on the plant’s life cycle and current stage of growth.
AnnualsPlants that germinate from seed, flower, set seed and die within a single year. Annuals are only able to spread by seed. Annuals can be further divided into summer annuals (which germinate in spring or early summer) and winter annuals (which germinate in late summer or fall). BiennialsPlants that usually live for two years. Seeds usually germinate and grow without flowering in year one and then grow a stalk, flower, produce seeds and die in year two. |

PerennialsPlants that can live for many years and do not die after flowering. Perennials can store food in parts of their structure that remain underground, allowing them to survive over winter and reemerge come spring. There are two types of perennials: simple and spreading. Simple perennials grow separately and have separate, vertical root systems. They spread only by seed. Spreading perennials grow horizontally and can spread by seed or vegetative reproduction. |

Now you can begin forming a vegetation management plan. The most effective programs are integrated and use both mechanical and chemical solutions to control weeds. Mechanical methods are great reactive means for immediate remedies, but long-term control requires herbicide applications. Preemergent herbicides in late winter or early spring can stop growth before it starts. Postemergent herbicides can help kill unwanted plants that have already sprouted. Using herbicides proactively can help lessen the need for mechanical removal, decreasing danger to applicators and saving land managers time, energy and money in the long run.
Because of the various weed life cycles, it’s crucial to also prepare yourself to take care of the fall germinating plants later in the year. Adding fall applications into your program can help you get ahead of weeds, break the cycle and ultimately have cleaner lands the following spring.
Whether it’s roadside, utility corridors, railroads or municipal sites, you’ll want to use vegetation solutions that address your unique needs while assisting you in being a proper steward to the land in your care. Envu representatives can provide you with information and tips on the best herbicides and modes of action for a strong integrated vegetation management program.
