Crabgrass is a widespread and vicious weed. It is quite resilient and reproductive. It will grow wherever there is the slightest crevice and grows quite well with a robust root system that is difficult to remove. It is adaptable to climatic conditions from temperate to tropical. It likes moisture, good fertility, light-loving, and not strict soil requirements, which can grow well on weakly acidic and weakly alkaline soil. It is planted in fast-spreading, healthy fertility, fast-growing plants, and many branches. After the invasion, it will quickly cover the lawn grass, causing a large number of bald spots and severely damage the decorative effect of the lawn, which is a vicious weed in the summer lawn.
- Morphological recognition
Annual weeds of grasses
Leaf-sheaths are shorter than internodes, sheath mouth or lower part sparsely pilose. Ligule obtusely rounded has 1 to 3mm long; leaf blade oblong-lanceolate has 4 to 12cm long and 5 to 10mm wide, sparsely pilose or glabrous. The spikelets are usually glabrous or adnate on both sides of the first lemma. Racemes 3-8, fingerlike at spike apex; two spikelets twinned on rachis side; first lemma usually glabrous or adnate on both sides pilose.
- Occurrence pattern
Crabgrass is slow to germinate at temperatures below 20°C and fastest at 25-40°C, and the optimum relative humidity for seed germination is 63%-92%. And it is very suitable for Optimal depth of the soil that is 1-5 cm. It can grow fast in Wet and light-loving, moist, and fertile ground environment. From the end of April to June, it can come out in large quantities. Till August and October, seeds side Mature sides shed and are vigorous in life. Mature seeds have dormant habits.
- Difficult to prevent
1. Not strict on soil requirements, can grow well on weak acid, weak alkaline soil.
2. It is fast spreading, with strong fecundity, fast-growing plants, and many branches.
3. It has a robust invasive ability, and can even invade the highly competitive communities such as dog’s tooth root and witch hazel.
Best Methods for Controlling Crabgrass
As the saying goes, it’s better to raise the soup to stop the boil rather than take the pot out of the fire. Where to pull and kill, but the spring comes again, and it is useless for you.
So first of all, you need to kill the crabgrass growth in the seed state. Since the germination of dandelion and martingale is very time-limited. So being able to suffocate them in the seed stage is the most important preventative work. There are well-established grass fertilizers and seed germination inhibitors on the market.

- Adjust the Mowing Height
Leave the grass of yours on the taller side, approximately 3 inches in length. Shade the soil is helped by taller grass blades. Leave lawn clippings behind to include all-natural shade and nutrients for the dirt. This can help stop the germination of crabgrass seed products.
- Get rid of Crabgrass by yourself.
Pull the lumps out, roots, and most. Try using a gardening weeder tool made to get rid of the origins of crabgrass. Usually, a claw is featured by these tools or perhaps plunger. You are able to drive deep into the floor, under the roots, to get rid of the plant. Although good at controlling crabgrass, this process will be time-consuming.

Ryegrass, early maturity grass, tall fescue, manila, dog’s tooth root, and other grass young lawn in the presence of Crabgrass can be used to prevent the use of Crabgrass clear – a bag to 15 kg of water to hit 330 sq. It is useful in preventing the removal of up to 4 leaves of Crabgrass, ryegrass, new fescue, tall fescue. Manila and other mature lawns can be used to remove the tip – a bottle of 30 kg of water to hit 667 square meters, effective prevention of 7 leaves, or less of the Crabgrass. The lawn of Bermuda, a dog’s tooth root can be used to prevent the use of chlorothalonil effectively.
When the grass appears on the lawn such as wheat, green onion orchid, frangipani, clover, horse-chestnut, etc., you can use bromegen or wormwood. The weed will be absorbed and spread to the whole plant, and after half a month, the grass will be dead and rooted.
If such weeds are present in hedges, color blocks, seedlings, or flowers, it is advisable to use Beben or Halothane after transplanting. It is effectively prevented.
- Encourage Certain Insects
This suggestion is most likely a little debatable because, in the experience of ours, the same folks that are attempting to eliminate crabgrass are incredibly likely not to want to get a group of pests or bugs in the yard of theirs.
