Question 1

How long after fertilizer application can I water my lawn?

Accepted Answer

You should wait 24 hours before watering your lawn after a typical treatment. This waiting window gives liquid weed control time to dry completely on weed foliage. After 24 hours, turning on irrigation safely activates the granular fertilizer beneath.

Question 2

Can I water my lawn 12 hours after fertilizer and weed control treatment?

Accepted Answer

Yes, you can water after 12 hours if necessary, provided the liquid weed control has fully dried. While two hours is the minimum drying time required, waiting 24 hours remains ideal for optimal performance.

Question 3

Will rain ruin my weed control application?

Accepted Answer

Rain will only ruin your weed control application if heavy downpours occur within two hours of treatment. Once the liquid product dries on weed leaves, rainfall will not decrease its effectiveness.

Question 4

What happens if granular fertilizer sits on the lawn without water?

Accepted Answer

Granular fertilizer sitting on dry grass remains completely dormant and inactive. If left dry for more than 10 to 14 days during hot summer weather, the fertilizer granules can cause turf burn.

Question 5

How soon can children and pets play on the grass after application?

Accepted Answer

Children and pets can safely return to the lawn once liquid weed control products have dried completely. In most cases, keeping family and pets off the grass for two to three hours is sufficient.

Question 6

Should I turn off my automated irrigation system on lawn treatment day?

Accepted Answer

Yes, you should turn off your automated sprinkler system on your scheduled treatment day. Leaving sprinklers on can rinse away fresh weed killer before technicians even finish their route.

Question 7

How much water is required to wash granular fertilizer into the soil?

Accepted Answer

Roughly 0.25 to 0.5 inches of water is enough to dissolve granular fertilizer and carry nutrients into the root zone. A single standard irrigation cycle usually accomplishes this goal easily.

Question 8

What should I do if a sudden storm hits right after my lawn technician leaves?

Accepted Answer

You should allow 10 days to monitor how well the weeds respond to the application. If heavy rain washed away the product and weeds persist, contact your lawn provider to request a free reservice call.

Question 9

Can watering too much make lawn care treatments ineffective?

Accepted Answer

Yes, overwatering causes severe soil runoff that flushes active weed controls and soil nutrients past the root zone. Excess water ultimately weakens your lawn and promotes new weed germination.

Question 10

How long should I monitor my weeds before requesting a free reservice call?

Accepted Answer

You should monitor your lawn for 10 days following a rain-impacted application. Most weed herbicides take up to two weeks to display visible curling, yellowing, and weed death.
