Narrow-leaf plantain is a potent weed that grows in different lawn conditions. Unlike most plants, the narrow-leaf plantain likes dry and alkaline-rich soil.

If you can identify them early, you can save yourself a big headache. Narrow-leaf plantains are challenging to remove because they develop deep root systems. You have to make sure you remove the entire root. Otherwise, it will grow back.

If you have a severe infestation of narrow-leaf plantains or broad leaf plantains, they may require herbicide.

A member of the buttercup family, this little yellow flower is one of the first to bloom in spring. You can find lesser celandines in woodlands, hedgerows, and gardens. The plant has glossy, dark green leaves and small yellow flowers.
