How To Get Rid of Weeds After Hydroseeding

Hydroseeding is a planting method where seeds, fertilizer, soil, moisture holders, mulch, and other stabilizers are sprayed into the ground at once. These elements are mixed in a tank and later pumped into the soil.

One of the advantages of hydroseeding is that it helps prevent the spread of weeds. However, you cannot completely avoid growing unwanted plants on your lawn. To control weeds in a hydroseed lawn, you can apply the following techniques:


You can use standard herbicides for weed control. Depending on the type of grass you planted in your lawn, choose the herbicide that kills weeds but does not damage your grass. Find out the type of weeds in your garden then research on the herbicide that controls them.

Tenacity herbicide can be applied to control crabgrass, oxalis, ivy, and other broadleaf weeds at the early stages of germination. Roundup is a selective herbicide that will kill weeds without affecting your plants. You can also apply Metrosine on your weeds but only after the plants are fully established.

Only spray the specific spots with weeds instead of drenching the soil. Ideally, targeting the leaves of unwanted plants would solve your weed problem. Herbicides can be effective for weeds such as oxalis, clover, and chickweed. Crabgrass is tougher to control using chemicals. 

Uproot the weeds by hand

If you have a small size lawn, you can identify the areas with a high concentration of weeds and uproot them by hand. This will work for crabgrass, which continues to thrive even when sprayed with chemical herbicides.

Uprooting is time-consuming, however, and might take you a few days to get rid of all unwanted plants. You can opt to ignore the crabgrass, as it is an annual plant, and wait for the next season.

You can then apply a crabgrass preventer on the soil during the subsequent spring, which will solve your problem. Ensure that you only use crabgrass preventers after planting your preferred grass seeds, as they might stifle early germination. 


Weeds will likely grow again in areas of your lawn that are patchy with grass. Therefore, it would help if you reseeded regularly to ensure your grass grows healthy and thick. An advantage of hydroseeding is that it facilitates rapid and dense grass growth in your garden. Weeds will struggle to flourish when they lack space. Proper grass care by watering, mowing, and fertilizing will choke out the weeds. 

Professional landscaping

When hydroseeding, you need a lot of experience and knowledge on how to apply the mix properly. You might damage your lawn by using too much water or fertilizer in your mixture, which can encourage weeds and crabgrass.

You can opt to work with a hydroseeding expert who will help you establish your lawn and control weeds appropriately. Ideally, you want your hydroseed lawn to thrive as quickly as possible.

A landscaping expert will get your yard up to your standards much faster. However, this option is expensive. A typical hydroseed lawn might require 4 to 5 hours of work to complete and additional hours to control weeds.

If you do not have the time to spray or uproot weeds and have the financial ability, a professional landscaper is the best option for managing weed growth. 


You should evaluate the resources available to you, both time-wise and financially, to determine the best method to control weeds in the hydroseed lawn.
