Popular Garden Summer Weeds
Based on the development stage, garden summer weeds are categorized into annual, biennial, and perennial.
Equally important, we can identify weeds by examining their structure and dividing them into grass and broad leaves.
Grass Weeds are monocotyledons from the Poaceae family that bear long leaves with parallel veins and hollow, rounded, closed, rigid stems.
Crabgrass is an annual summer weed native to Eurasia, growing from spring to late summer.
Their light green leaves are curly along the margins and are covered with large stiff hairs.
Additionally, the weed has green flowers with 3 to 5 spikes forming a long cluster on one side of the flattened stalk.
Crabgrass reproduces by tiny, round seeds that appear like a small corn plant.
2. Barnyard Grass
Do you know Banyard grass is toxic due to the presence of nitrates in the large amount?
Barnyard Grass is an annual weed native to Asia. You can find their clustered blooms on long branches with heads standing erect.
Besides, the weed has flat, folded leaves with a distinct midvein that bears opened or flattened leaf sheath and a rough surface on both sides.
3. Goose Grass
Goose Grass has smooth, open, flat foliage with long hairs at the base around the collet. Its leaves have short membranous spikes at the top of the collet region.
Endemic to Eurasia, it reproduces by tiny seeds attached to the zipper appearance in the spike, forming at the tip of the seed stalk.
As the plant matures, it bears a white crown and a lower flat stem with clustered flowers along the spikes.
Sandbur has dull green, smooth, flat foliage folded lengthwise and rolled up on edge. Its leaves have a linear shape with rough upper and smooth lower surfaces.
It is native to Eurasia, Africa, and South Pacific.
Sandbur produces pointed flowers in clumps enclosed in the round, spine-covered Bur, which is its distinctive feature.
Besides protecting the roots, Bur also produces seeds and keeps them viable for years in the soil.
5. Yellow Fox Tail
It is a common annual weed, native to Europe.
Yellow Fox Tail’s tall spikes appear needle and thread-shaped, with its bright yellow flower being its central attraction.
It has alternate, linear, flat, loosely spiral leaves with long velvety hair at the bottom at maturity.
Besides, it produces a seed with a yellow, cylindrical head composed of many tightly packed single-flowered spikelets.
Broadleaf weeds are dicotyledonous that have broader leaves with distinct veins.
Over time, these weeds may be the hidden reason for destroying your turfgrass stand.
Chickweed is an annual summer weed native to Europe and Asia.
You can distinguish it by its oval-shaped leaves with pointed tips and hairy margins at the base growing opposite each other.
Likewise, the plant produces star-shaped flowers with five-lobed petals held by a loop of five sepals from below.
Chickweed is an invasive weed that produces reddish, brown, and yellow rounded seeds with a flat top.
7. Carpet Weed
Carpet Weeds have small white flowers found in the leaf axils, which bloom in mid-late summer.
These annual broadleaf weeds are native to America.
Lambsquarter has trigonal leaves with gray undersides, covered with white coating in the newly grown foliage.
Likewise, it has modest green flowers with dense and granular clusters at the end of the stems. Its scant flowers lack petals and bloom from May to November.
Lambsquarter grows annually and is inhabited throughout Europe and Asia. Further, it has round and black seeds, which are narrow with parallel edges.
Purslane is the annual summer weed native to Eurasia and holds medicinal value.
Apart from having healing ability, it is a prolific seeder producing round-shaped seed capsules.
Purslane leaves are thick, fleshy, spoon-shaped, and broadest near the rounded tip. Its leaves are succulent, mainly attached to the branching stem rather than the main stem.
10. Prostrate Knotweed
Prostrate Knotweed grows annually that has alternate, linear, and stalkless leaves.
Young leaves are dark green and longer, while the size gets smaller, and the green color fades away in mature leaves.
The plant is native to Europe, Asia, and America and reproduces with brown, narrow, and rounded seeds with a powdery white coating at its tip.
Prostrate Knotweed has a tiny, white, and yellow flower in clusters at the leaf axils. Moreover, its flowers grow from the base of the leaves and bloom in mid-summer.
