Based on their nature, weeds are divided into annual weeds and perennial weeds
1. Annual Weeds
Broadleaf winter annual weeds:
- Seeds germinate from late summer through fall
- Weeds over winter and continue to grow in early spring
Broadleaf summer annual weeds:
- Seeds begin to germinate as soils begin to warm up
Grassy winter annual weeds:
- Seeds germinate in late summer to early September
Grassy summer annual weeds:
- Seed germination begins in early to mid-spring
- Seeds continue to germinate in the summer
2. Perennial Weeds
Broadleaf Perennial Weeds:
- Perennials are persistent from year to year
- Range from weeds that are easy to eliminate, to some of the most difficult to control
Grassy perennial weeds/Sedges:
- Some of the most difficult weeds to control in a lawn
- Total lawn renovation is usually necessary
Other classifications include common weed, easy to control weeds, difficult weeds, and Trees and Stumps.
Small standing trees and roots are also unwanted and categorized as weeds. The way to cope with them is to use an axe to cut then down (from November to March).
Various control measures to get rid of weeds include pulling weeds, digging weeds, mulching, cultivating, reducing, reseeding, crowding plants, glyphosate herbicide, organic herbicides, corn gluten herbicides, and flamers etc. Choose one that suits the plant and your budget, and keep your garden free from weeds.
