when using the seed program can i see that day or should I wait.
This will be my first year using your program rather than using Scotts .
I’ve read a lot of good things about your products.
Jonathan Green | March 20, 2017 at 12:23 pm
You can seed and apply Crabgrass Preventer plus New Seeding Fertilizer and Mag-I-Cal all on the same day.
Anthony Brown | May 12, 2017 at 11:21 pm
Hope your yard came out as nice as mine. Love this product. Beautiful grass. First time using it. Scotts is not the product that I will buy again.
Michele Robinson | March 20, 2017 at 12:02 pm
Hello fellas, it’s me again! My nursery doesn’t carry Crabgrass Preventer plus New Seeding Lawn Fertilizer. What should I use in place of it?
Jonathan Green | March 20, 2017 at 12:26 pm
You can use Green-Up for seeding and sodding and then after the new seedlings have been mowed 3x, apply Crabgrass and Weed Preventer.
Christopher Molinaro | March 22, 2017 at 9:26 am
So is the Crabgrass Preventer And the Magical Product something I want to use, if I reseeded in the fall and have not yet applied anything this spring? Or do I go a different route?
Jonathan Green | March 22, 2017 at 10:04 am
Follow our Standard Seeding Wheel (the first wheel on this page) http://www.jonathangreen.com/application-wheel. Fall seeding is preferred as warm soil temperatures and reduced pressure from germinating weeds yield the best results.
Christopher Molinaro | March 27, 2017 at 2:08 pm
ok so being that I overseeded in the fall, there’s no need to overseed again this month?
Jonathan Green | March 27, 2017 at 2:26 pm
Not unless you have bare dirt spots that need to be filled in.
Gary Lima | March 23, 2017 at 1:44 pm
Hi I overseered with black beauty late last fall but I think it was to late. nothing came up.
Will it come up this spring? Or do I need to reseed again
Jonathan Green | March 23, 2017 at 1:56 pm
Dormant seed should come up if the seed was covered by a little soil and when the soil temperatures have reached 55° for about a week. It is still too cool out.
Gary Lima | March 23, 2017 at 2:49 pm
Ok thanks so don’t put crab grass prevented down
Jonathan Green | March 23, 2017 at 3:13 pm
You can apply Crabgrass Preventer plus New Seeding Fertilizer.
Zachery Miera | March 25, 2017 at 1:12 pm
Hi I plan to over seed around the 2nd week of April. I plan to apply Black Beauty Heavy traffic grass seed, Mag-I-Cal, and Green Up for seeding and Sod all at the same time. Do you recommend that I top dress the yard with a little soil as well or will raking it in do the trick?
Jonathan Green | March 27, 2017 at 9:15 am
If the soil is rich and in good shape, raking will be fine. Adding top dressing is beneficial as it adds organic material to the soil and provides a nice cover for the grass seeds.

Hi guys, im a newbie with lawn and seeding. Im using 3 different seed products on my lawn areas, black beauty ultra mix, dense shane and full sun. I started seeding in early march this year. I have prep my soil with love your lawn and magi-cal and had great result when my seeds were sprouting. I later found out that i can use the crabgrass preventer 1st step for seeding. So on my dens shade area, i prep my soil with love your lawn, magi-cal then 3 days after applied the crabgrass preventer. On that afternoon of that same day i applied my denseshande seeds. Theyve grown really well its only been in 2.5 weeks and theyre about 2.5 to 3 inches estimated height.
i was looking at the new seeding wheel, it does say i can use magical and crabgrass preventer for early spring, And another process on late spring, summer and fall.
My question is whats the sequnce in applying thr products?. Do i apply magical the 1st week then 2nd week crabgrass preventer then alternately applying them through appril?
For the green up weed and feed, how often do i apply them for late spring. Is it every week.
Im just afraid i might do harm and do good on my grass
Jonathan Green | March 27, 2017 at 9:13 am
Mag-I-Cal and Crabgrass Preventer plus New Seeding Fertilizer are only applied once as spring applications. Green Up Weed and Feed is applied once 6 weeks later. Apply products once according to the square footage of your lawn.
CHRISTINE BRENNING | March 27, 2017 at 5:18 pm
if we put down the crabgrass preventer and fertilizer tomorrow, my husband wants to know if he wants to put some grass seed here and there when is it safe.
Jonathan Green | March 28, 2017 at 10:22 am
You cannot seed for 4 months after applying Green Up with Crabgrass Preventer. Ether use this product and wait until fall to seed, or use Crabgrass Preventer plus New Seeding Fertilizer.
Jennifer | April 1, 2017 at 2:59 pm
It’s April 1st in Long Island NY and I noticed that, weeds have already started to pop up before I could get to putting on Crabgrass Preventer w/ plus new seeding fertilizer (I need to seed in spots). Is it going to be too late for it to really be of any use? The forsythias are not in full bloom but the buds have definitely swelled. Also, I know I am able to seed on the same day BUT could I also wait a few weeks until it is a little warmer and I’m actually around to water? Thanks.
Jonathan Green | April 3, 2017 at 8:28 am
It is not too late. Crabgrass will not germinate until the soil temperature reaches 60°. We would advise waiting a couple of weeks. The seed will not germinate until the soil temperature reached 60° either.
Gary Possley | April 2, 2017 at 10:05 am
What should the ground temp. be for using crabgrass killer green up and magical in northern Illinois ?
Jonathan Green | April 3, 2017 at 8:18 am
Crabgrass preventer should be applied when soil temperatures reach 50 to 55°. If you apply the herbicide too early in the spring, it may break down before the end of the germination cycle.
Michele | April 3, 2017 at 10:58 am
Should I mow lawn before I apply Mag-I-cal and Green Up for Seeding and Sodding?
Jonathan Green | April 3, 2017 at 12:21 pm
A mowing a few days before is advisable if the grass is over 3 inches long.
Ron | April 7, 2017 at 6:51 pm
Seeded last fall have a few bald spots. Want to apply Crapgrass Preventer plus Mag-I-Cal
Monday. My guestion is do I need to water ?
Also at what settings to I apply each using a Scott drop spreader?
Jonathan Green | April 10, 2017 at 9:09 am
Apply both of the products and then water them both in at the same time. Visit our Spreader Settings page for all of our settings.
Erik | April 14, 2017 at 7:46 pm
I live in the west suburbs of Chicago. I’m wondering about a good seed to use.
Jonathan Green | April 17, 2017 at 8:37 am
If you have full sun to partial shade conditions, Black Beauty Ultra grows well in your area.
Tanya | April 19, 2017 at 6:52 am
If I used Crabgrass preventer with green up can I still use the Crabgrass preventer with seeding ?
Jonathan Green | April 20, 2017 at 10:27 am
Seed will not germinate if you have used Green Up with Crabgrass Preventer. If you are seeding a different area, you can use the Crabgrass Preventer plus New Seeding Fertilizer.
Tanya | April 22, 2017 at 7:24 am
How long should I wait before I try to seed? Please advise thank you.
Jonathan Green | April 24, 2017 at 9:10 am
You must wait 4 months to seed after applying Green Up with Crabgrass Preventer. It will be summer at that time so we advise waiting until mid to end of September.
Mehdi | April 19, 2017 at 7:26 pm
I went ahead and used the organic crab preventer but noticed i started having too many weeds. is it tool late to switch back to the second wheel application and over seed in the fall?
Jonathan Green | April 20, 2017 at 10:26 am
You can switch back and forth. For existing weeds, we suggest applying Lawn Weed Control, a granular herbicide.
Michele | April 20, 2017 at 9:48 am
My neighbor backyard is pretty bad shape! Dry soil that has cracked, lots of dead grass and huge bald spots. What do you recommend.
Jonathan Green | April 20, 2017 at 10:24 am
We recommend having a soil pH test done and adjust with Mag-I-Cal as needed. We also recommend applying Love Your Soil as the cracking could indicate compaction.
Michele | April 22, 2017 at 9:08 am
I live in northern nj. Can i use magi cal without doing a ph test first. I heard the soil here is acidic. Also do you apply mag ical with crabgrass preventer mixed with drop spreader or two seperate applications. Thank you
Jonathan Green | April 24, 2017 at 9:17 am
The soil in NJ does tend to be acidic but we do suggest a soil pH test. Many times garden center and hardware stores will do this for free. You can apply the Mag-I-Cal and the Green Up with Crabgrass Preventer on the same day but not mixed on the same spreader.
Michele Robinson | April 23, 2017 at 9:58 am
I have friend who has clay soil. After seeing my lawn he wants to know what products to use on his. He is thinking about digging up lawn and replacing it with top soil. Is there a short cut to get his lawn established.
Jonathan Green | April 24, 2017 at 9:23 am
Love Your Soil will help to alleviate the compaction of the clay soil. It can be applied as often as every 6 weeks if needed. Tilling top soil into the top 6 inches of his soil will also help and may be a good idea.
Mary | May 2, 2017 at 8:56 am
i used Green Up with Crabgrass Preventer in late March. Was that too early for the Jersey Shore? Should I now apply Weed and Feed? Should I have seeded first along with Green Up, then applied Crabgrass Preventer? I have full sun, and crabgrass is a concern. When can I seed? In the fall?
Jonathan Green | May 2, 2017 at 11:06 am
That was a bit early. To extend your crabgrass control, apply Crabgrass and Weed Preventer at the end of May. This product has no fertilizer and will not interfere with the Green Up Weed and Feed. Apply the Green Up Weed and Feed to a damp lawn the next time no rain is predicted for 48 hours. We recommend fall seeding. Warm soil temperatures and reduced pressure from germinating weeds yield nice results.
Sue | May 17, 2017 at 11:39 am
Our organic lawn care service never showed so I am trying to do it this year on my own. I am late to the game but our yard has weeds all over! I was thinking my first application should be the green up weed and feed lawn food and then apply it again 30 days later. Is that correct?
Jonathan Green | May 17, 2017 at 12:11 pm
Yes, you can reapply in 30 days but do not apply it if temperatures are 85 degrees or higher or if it is humid.
Josh | May 18, 2017 at 8:40 am
I just applied gypsum and Scott’s starter fertilizer to my new lawn. Want to switch over to Jonathan Green. How long do I need to wait to apply love your soil (I have bad clay soil) and start with the rest of the program? I also need to put down more grass seed as the landscape contractor didn’t do a very good job.
Jonathan Green | May 18, 2017 at 10:33 am
Wait 2 months before applying Love Your Soil. Please email us at email@example.com. We need to know your location to best advise you. Please tell us your sun and shade conditions and if possible, what type of grass seed was just planted and what type of products were used and when.
Bill McKenna | May 20, 2017 at 12:47 pm
So, the only thing that goes down in the fall is the love your soil product?
Jonathan Green | May 22, 2017 at 9:11 am
We recommend Love Your Soil in July or August and Winter Survival in September or October.
Bill Bakker | May 22, 2017 at 11:30 am
We live at Jersey Shore we applied 3/12/17 first treatment CrabGrass Preventer and Mag-i-cal silver bag and Green up Blue & white bag 5/1/17 applied Green up weed & feed yellow bag & crab grass preventer purple bag My ph is 6.1 but still get some weeds Question is what is next steps?
Jonathan Green | May 22, 2017 at 12:11 pm
You are doing great! The next application we recommend is Love Your Soil in July followed by Winter Survival at the time you are over seeding. (Mid September is a good time for this). As your lawn thickens and your pH improves, the weeds will diminish.
Michele Robinson | May 30, 2017 at 12:42 pm
I just mowed my lawn and I see a lot of yellow grass blades. How do I correct this to make my lawn green again. And there are clovers in the grass also.
Jonathan Green | May 30, 2017 at 1:04 pm
It could be hungry, stressed or have a turf disease. Please send a few, good quality close-up photos to firstname.lastname@example.org. We need to see what is going on in order to best advise you.
Michele | June 12, 2017 at 8:49 am
I have some spots in yard where the grass is burnt. How do I correct.
Jonathan Green | June 12, 2017 at 8:52 am
Water heavily for one week to try to save grass burnt by fertilizer. Reseed damaged areas in the fall.
Robert | June 14, 2017 at 8:17 pm
I am about to apply late spring here in the Chicago area. what is the pet policy regarding letting my dogs on the lawn??
Jonathan Green | June 15, 2017 at 9:04 am
Jonathan Green’s organic products are safe for children and pets immediately after application. These products contain feed-grade ingredients, commonly used in animal and pet foods.
After applying these products, water your lawn to move the fertilizer to the roots. Once the grass has dried, people and pets are safe to re-enter the lawn area.
Lawn Weed Control and Green Up Weed & Feed:
Lawn Weed Control and Green-Up Weed & Feed are used to control and suppress broadleaf weeds. In order to work properly, they should not be watered in. Therefore, it is safe to re-enter the lawn area 48 hours after application. In this time the product has moved from the plants leaf to the roots, making it safe for children, dogs, cats etc.
Follow all label directions for products that contain pesticide controls for re-entry instructions. All control products have been screened by the Federal Environmental Protection Agency (EPA) and are properly labeled for use on lawns or gardens. Please read and follow all label directions.
Rashaun Cherry | July 31, 2017 at 10:42 pm
Hey guy’s I pretty new here! I have been using Scott’s/ True-Green for about 3 years now. I’m green the results I’m looking for. There last application was about 2 weeks ago I have 2 more then I’m done with them! So my question is where on the wheel should I start and when?
Jonathan Green | August 1, 2017 at 9:33 am
Jump on the Standard Program Wheel at the July/August application of Love Your Soil. This is an all organic soil food and will not interfere with other products that have been or may be applied. http://www.jonathangreen.com/application-wheel
Rashaun Cherry | August 4, 2017 at 2:25 pm
Thank You! What seed should I use for over seeding?
Jonathan Green | August 4, 2017 at 2:29 pm
What are your sun and shade conditions and what state are you located?
Rashaun Cherry | August 4, 2017 at 2:34 pm
Very sunny No shade at all. I’m in South Holland, IL
Jonathan Green | August 4, 2017 at 2:39 pm
We recommend Black Beauty Ultra for your area and conditions.
Rashaun Cherry | August 4, 2017 at 2:58 pm
Ok Thanks ! I’m very excited to see the results!
Shirley | August 5, 2017 at 6:25 pm
We have a side walk grass that was now pure crabgrass weeds. Can I dig up all of it and then apply Mag-i-cal and Love Your Soil at the same time to prepare for seeding this fall with Black Beauty? We live in North East Boston area.
Jonathan Green | August 7, 2017 at 8:58 am
Yes, but we suggest waiting until the beginning of September. If we get an August heat wave, the young seedlings may not survive.
Todd In Essex NJ | September 4, 2017 at 8:59 am
I reseeded 1/2 my back yard spring 2017. Now that it’s fall I’d like to know the best way to wipe out. Crab grass in other areas. I used grab grass preventer earlier this year on the entire lawn and fed with green up in July.
Jonathan Green | September 5, 2017 at 10:44 am
Crabgrass is an annual and will die out with the first frost. Over seed around it and over it. Next year, we suggest an application of Crabgrass and Weed Preventer to extend your crabgrass control.
Todd In Essex NJ | September 5, 2017 at 11:09 pm
Should I kill off the crab grass now before a fall overseed?
Can you suggest a product?
I did apply the crab grass preventer this year and I’m not sure it did much at all
Jonathan Green | September 7, 2017 at 4:04 pm
Crabgrass is an annual and will die of with the first frost. Overseed right around it and over it. Next year, we suggest an application of Crabgrass and Weed Preventer the first week of June to extend your crabgrass control.
Rob | September 5, 2017 at 9:40 pm
Hi. I live in central NJ and I am looking for suggestions. I am going to do core aeration this weekend and would like to overseed as well as apply fertilizer. My yard is primarily sunny but I do have a few shade areas. What products do you recommend I use this week and in what order?
Jonathan Green | September 7, 2017 at 4:02 pm
We recommend Black Beauty Ultra. If you wish to do 2 fall feedings, seed with Green Up for Seeding and Sodding and then follow up with Winter Survival at the beginning of November. Alternatively you can use Winter Survival as your seeding fertilizer. You can apply the seed and fertilizer in any order after you aerate. We recommend Black Beauty Ultra to seed with for your area and conditions.
Rob | September 7, 2017 at 10:04 pm
Thank you for the advice. I forgot to ask about “love your soil”. Should I apply this as well. My yard is primarily clay.
Jonathan Green | September 8, 2017 at 8:43 am
Love Your Soil may also be applied on the same day. For yards with clay soil, you may want to try applying Love Your Soil in the spring and the fall. It will help your new seedlings establish better root systems.
