What are annual weeds?<\/span><\/h2>
Annual weeds are simply unwanted plants that only last a single growing season (roughly 12 months) but never beyond that. This means they\u2019ll sprout, grow, flower, produce seeds, and die within 12 months. Since they live such short lifespans, annual weeds usually have showier flowers that last much longer than their perennial counterparts.<\/p>
Annual weeds can be further divided into two categories depending on their growing season: summer annuals<\/strong> and winter annuals<\/strong>.<\/p>
Summer annuals<\/span><\/h3>
Also known as warm-season annual weeds, these weeds germinate in the spring and grow, bloom, and make seeds throughout summer. Summer annuals are more cold-sensitive, dying by the time the first frost comes.<\/p>
Here are some common summer annual weeds:<\/p>
- Crabgrass<\/a><\/li>
- Prostrate knotweed<\/li>
- Goosegrass<\/li>
- Southern sandbur<\/li>
- Spurge<\/li>
- Purslane<\/li> <\/ul>
Winter annuals<\/span><\/h3>
In contrast to summer annuals, winter annuals are more sensitive to heat. Also known as cool-season annual weeds, they sprout from late summer to early fall when temperatures start to cool down. They grow throughout fall, lay dormant in winter, and reemerge in spring. They then bloom from spring to summer before dying.<\/p>
Here\u2019s a list of some common winter annual weeds:<\/p>
- Annual bluegrass<\/a><\/li>
- Common chickweed<\/a><\/li>
- Henbit<\/a><\/li> <\/ul>
What are perennial weeds?<\/span><\/h2>
Unlike annual weeds, perennial weeds live for multiple years and become dormant during the winter. They usually last three or more growing seasons, blooming year after year. <\/p>
Perennial weeds are able to live as long as they can because of their hardy root systems, which can store energy that keeps them chugging through the winter. These root systems \u2014 typically with a central taproot \u2014 also make perennial weeds very difficult to get rid of. Perennial weeds can regrow from root fragments, so you need to take out the whole root system in one go to keep them out of your lawn for good. <\/p>
Methods to kill weeds permanently<\/a> from the root include herbicides, hand-pulling, weed-burning, smothering, and natural remedies like salt, vinegar, or boiling water. However, these methods can be tricky, because most of them will kill your grass along with the weeds. That’s part of what makes perennial weeds so hard to get rid of. <\/p>
Perennial weeds can be further classified into simple perennials<\/strong> and spreading perennials<\/strong>.<\/p>
Simple perennials<\/span><\/h3>
Simple perennials are perennial plants that spread only through seeds. They grow alone. Single perennials that grow near each other are separate plants rather than one big plant. Because of this, they\u2019re also called solitary perennials.<\/p>
Here are some examples of simple perennial weeds:<\/p>
- Dandelions<\/a><\/li>
- Plantain<\/li>
- Chicory<\/li> <\/ul>
Spreading perennials<\/span><\/h3>
Unlike simple perennials, spreading perennials spread through more than just seeds. They have special structures like rhizomes (underground stems) or stolons (above-ground stems) that spread horizontally, sprouting new \u2014 but identical \u2014 plants. This process is called vegetative reproduction, and it produces clones of the parent plant.<\/p>
Also called creeping perennial weeds, they can take over an entire lawn or garden within a few years if left unchecked<\/p>
Some of the most notoriously difficult to eradicate weeds are spreading perennials, including:<\/p>
- Ground ivy (creeping Charlie)<\/li>
- Poison ivy<\/a><\/li>
- White clover<\/a> (and other types of clover<\/a>)<\/li>
- Nutsedge<\/a><\/li>
- Quackgrass<\/li>
- Oxalis (however, it can also act as an annual depending on the climate)<\/li> <\/ul>
How to control annual vs. perennial weeds<\/span><\/h2>
Annual weeds are much easier to control than perennial weeds, but perennial weeds are typically easier to keep out of your yard in the first place because they don\u2019t reseed themselves like annuals. Let\u2019s see how different weed control measures stack up against annual and perennial weeds.<\/p>
