Several bags of lawn care products I bought
got wet in the bag. Are they still good?
|
 |
It depends on what they are and how much moisture they absorbed.
Fertilizer is okay if it can be crumbled into spreadable particles.
If dried clumps shatter easily when you tap them with a hammer, the fertilizer
is still usable. But don't try to use any fertilizer unless it's dry and pulverized
into individual pieces. Large chunks of fertilizer can damage grass, so if you
can't spread it, don't use it.
Weed & Feed and Crabgrass Preventer lose their effectiveness
soon after they get wet. If the product was wet when purchased, let us know or
discuss the problem with your retailer.

|
Can lime and fertilizer be applied on the same
day?
|
|
Yes, as long as you don't apply more than of 50 lbs. of lime
per 1,000 square feet. Also, avoid mixing the products which you put into your
spreader at the same time. Instead, apply them separately.
|
|
How do I know what number to set on my fertilizer
spreader?
|
|
Click Here for Spreader Settings. You
will find the spreader settings for many of the most common spreaders on the
back of bags. If you have any questions, you can call our Consumer Service
Hotline or contact us for assistance.

|
I spread the fertilizer, but my lawn didn't turn
green. What happened?
|
|
There are three likely causes: too little fertilizer, lack of
water, or you could have fertilized your grass at the wrong time. To learn more
about when to fertilize your particular type of grass, go to Lawns.
To see if you didn't get the right amount of fertilizer on the grass, check
the spreader and bag to see if you used the proper setting. Make sure your spreader
isn't clogged. Also recheck your math to make sure that you correctly estimated
the area of your lawn and that you applied the right amount of fertilizer for
the size area. Coverage is given in square feet on the front of the bag.
Fertilizer needs to be watered in by rainwater or water from a sprinkler before
it can reach grass roots. If you think your lawn has received less than 1 inch
of water since you fertilized it, water it now and see if this corrects the problem.
You should see noticeable greening within 3 to 5 days.

How soon should I water after applying fertilizer?
|
|
Fertilizer Only: Water immediately after applying fertilizer,
or at least within 24 hours. The water begins the fertilizer release process,
and it will also help avoid burning by granules that are resting on the leaves.
The green, Polyon timed-release fertilizer will not burn your lawn when used as
directed, because they are designed to feed safely and evenly over time. But every
mix contains some fast release nitrogen to green up your lawn right away. Water
carries this nitrogen to the root zone and greatly reduces possible injury to
existing blades of grass.
Weed & Feed: Water your lawn before application to help the product
stick to leaves, but don't water again for 24 to 48 hours.
Crabgrass Preventer: Water in well after applying to help the product
soak into the top few inches of soil.
|
|
How soon can I aerate my lawn after applying
a Weed & Feed?
|
|
We recommend that you wait at least 2 weeks. This gives the products
ample time to work, and gives your grass a chance to fill in areas where weeds
were growing. Also keep in mind that aerating works best when done in the proper
season. Aerate your lawn after it shows signs of vigorous new growth.
|
|
How soon can I aerate my lawn after applying Crabgrass Preventer?
|
|
It is best to aerate the lawn before applying crabgrass preventer
containing Dimension®. If you must do so after, which would be the case with
warm season lawns, wait at least 4 months after applying Crabgrass Preventer
with Dimension.
|
|
How soon can I sow seed after applying a weed
control product?
|
|
In this case, it is essential to check information on the bag.
Because weed killers vary in their ability to linger and prevent seed from coming
up, the answer will depend on the product. Always follow the label directions.
Crabgrass Preventer: Do not sow seed within 4 months of applying crabgrass
preventer. By fall, which is the best time to sow seed of cool-season grasses
anyway, you should get good results from seeding. You can plant sod in areas treated
with Crabgrass Preventer after 1 month.
Weed and Feed: You will get better germination if you do not use Weed
and Feed for at least four weeks prior to planting seed.
|
|
Can I use Crabgrass Preventer with Dimension
in vegetable and herb gardens?
|
|
Absolutely not. It is only for use on lawn grasses and some ornamentals.
Always read the label directions carefully before applying any product.
|
|
I’ve used Weed and Feed but it didn’t
work. Why?
|
|
This is a common complaint because weed-and-feed products need
certain conditions to be effective. Here are six reasons why it may not have worked.
- There was poor contact with weeds. Don’t mow immediately before applying.
Instead, mow your grass two days before applying Weed and Feed to stimulate growth
of weeds. Weed and Feed works best on broadleaf weeds that are actively growing.
- The weeds are grassy. Weed and Feed kills broadleaf weeds such as dollarweed,
dandelion, and plantain. To control crabgrass and other grassy weeds, use Crabgrass
Preventer rather than weed and feed.
- The weeds are large and mature. If weeds are not actively growing, the product
can’t be as effective. For best results, apply early in the growing season
while weeds are young and still actively growing.
- The weather is too cool or too warm. It’s best to use Weed and Feed in
spring or fall. Again, this is when weeds are actively growing. When the weather
is too cool or too warm, the weeds just sit there, not really growing.
- The Weed and Feed granules were washed off the foliage by rain or watering
within 2 days after applying.
- The weeds in your lawn are not listed on the label. Although Weed and Feed
is effective on most broadleaf weeds, there are a few that are immune.

Are fertilizers harmful to birds or pets?
|
|
Fertilizers that don't contain herbicides or pesticides shouldn't
harm birds or pets. As a rule, it's a good idea to water thoroughly after applying
to help wash granules into the soil and off the grass blades.
The situation is different with broadleaf weed killers, which work by sticking
to the leaves. They should not be washed off for at least 48 hours after application.
During this time, keep pets and children off the treated area.
Label directions on pesticide products generally say to keep anyone, other
than the applicator, out of the treated area until the spray has dried or the
dust has settled.
|
|
Is fertilizer safe to use around pets and children?
|
|
Yes, fertilizers can be used around pets and children, but it's
essential that they be stored well out of childrens' reach. Also, have your children
play elsewhere while you are applying fertilizer. Invite them back when the fertilizer
has been watered in and the grass has dried.
Never allow children to handle fertilizer. Fertilizers can be harmful if swallowed.
Be sure to read all caution statements and directions on the package before applying.
|
|
I applied too much fertilizer to my lawn. What
should I do?
|
|
The best thing to do is to remove as much fertilizer as possible.
If it's soon after application, you can run over the lawn with a mower that has
a bag attached. Mowers create a vacuum effect that can pick up some of the excess
fertilizer. If your lawn is small, you can also use a wet/dry shop-type vacuum
to pick up the extra fertilizer.
If you can’t do either of these things, water thoroughly (at least an
inch) for 4 consecutive days. There is no guarantee that this will work, but taking
these steps may reduce potential damage.
Lawn damage from too much fertilizer or spilled fertilizer is often caused
by excessive salts in the soil. After removing as much fertilizer as possible,
flushing the area with water to dilute the salts and move them below the root
zone is the only way to minimize damage.
|
|
I applied too much Weed and Feed. What should I do?
|
|
Flush the area with 2.5 to 5cm (1 to 2") of water daily
for 3 to 4 days to minimize potential damage to your lawn. Do not make another
herbicide application until next year.
