Frequently Asked Questions

Twin City Seed Co is invested in the success of your seeding whether it’s a lawn, a golf course, a roadside, a prairie, a field of alfalfa…you get the idea. We’ve tried to anticipate your questions, so we think you may find the answers you are seeking right here! If for some reason you do not, please email us at info@twincityseed.com or visit our contact page.


The best time to seed is going to be in the Spring or Fall.

Timeframes will vary depending on where in the country you are located. For example, Tall Fescue, when living in a colder climate, should be planted earlier in the fall to allow it time to establish roots.

While planting in the Spring or Fall is a generalization, seed according to packaged seed instructions. 

Crabgrass is a common problem when establishing a lawn from seed. If you try to apply a preventative prior to seeding, your lawn will not grow. While you should always read instructions before applying any crabgrass prevention, we recommend waiting until you’ve mowed your new lawn at least three times.

At the beginning of a new lawn establishment, you will want to keep the seed moist until the seed begins to germinate. Continue watering frequently, multiple times per day, until the majority of the lawn has germinated. At that time, you want to back off watering to once in the morning and once in the evening. Too much water can be a bad thing after a lawn’s establishment. Eventually, you will set a normal irrigation cycle or water on an as-needed basis. If it’s a shadier property, it will take longer to dry out, so keep an eye on it. Some parts of your property may not need watering as frequently as other parts based on sun exposure.

The biggest difference between Dense Shade and Shady is how many hours of sunlight an area receives. If the area receives approximately four hours of sunlight then Dense Shade is your best option. If the area receives light filtered sun throughout the day, Shady is the best choice. A note, Dense Shade mixes will not need to be mowed as frequently as a normal lawn; every other week at most.

Poor soils and minimal irrigation call for Tuff Turf. This is one of TCS’s biggest sellers. Not many people have irrigation, and a lot of home lawns have bad soils from when their house was under construction. It’s a very common situation.

Tuff Turf is TCS’s best recommendation for sandier ground if you want a traditional-looking yard. It’s deeper-rooted and very drought tolerant.

If even Tuff Turf struggles to take root in your yard, you may want to begin adding organic matter into the soil. Don’t bag your clippings, but leave them on top of your lawn, and start using organic fertilizer. It may take a while, but you will start seeing the benefits over time.

Yes, you can use a shade mix in a sunny yard. These mixes include more fine fescues, which will look different from kentucky bluegrass, turf type tall fescue, and perennial rye, but they will grow just fine. 

Depending on the amount of shade, it is most likely not worth trying to use a sunny mix in a shady yard. It will germinate, but eventually, it will die off. 

Sunny mixes are ones that contain a high amount of Kentucky Bluegrass or Perennial Rye. If your yard is both sunny and shady, it’s best to get sun/shade. Or decide to use a sunny mix for the sunny front yard and a more shade-tolerant mix for the backyard.

Well, this is not going to provide you with the best results. In fact, you may only get 20% seed germination.

For the best results with minimal effort, you need to have a good seed-to-soil contact. We recommend:

1) aerating the lawn

2) slit seeding (a mechanical method of planting grass seed that combines a bit of dethatching with seeding)

3) applying fresh black dirt with a garden rake

If you seed this way, it is best to do it in the Fall before Winter (in areas where there is snowfall), allowing the snowpack to help press the seed into the soil. 

For every new seeding, it is a good idea to use a starter fertilizer. This can be done at the same time as seeding or just after seeding, but you want to make sure the seed has everything it needs to grow.

Low Grow is not designed to be regularly mowed. We typically advise mowing Low Grow once in early fall to clean it up. If you like the whispy look, you can try and mow it before it goes into summer dormancy. This is trickier to do because of weather changes, but this is how golf courses achieve that whispy look throughout the playing season. Mow at the highest setting, and time it so it regrows sufficently enough before the heat of summer in your area. In Minnesota, that is roughly the end of May to early June, but the weather varies.

If you do want to mow, we recommend every 5 weeks or more at the highest setting. Please note that regular mowing will cause a decline in the turf stand.

Low Grow should be watered in the beginning through germination and establishment like any lawn-starting seed. After establishment, it is best to quit regular watering unless your area experiences a significant drought. Too much water can cause it to come in too thick for most customers’ preference. 

For those with a lot of dogs, it’s best to use TCS’s Tuff Turf Mixture. It is a stronger rooted mix making it sturdier and more difficult for animals to rip it up.

When starting this mixture, it’s best to section off the property and establish it in quadrants. If you’re not able to do that, plan to overseed for a few years. Ideally, you want to keep your dogs off the newly established yard for 30 days or more. That may be a difficult taskm but it will give you a better lawn.

To achieve a darker-hued lawn, try overseeding with one of TCS’s elite bluegrasses. Doing this regularly in the Fall or Spring after aerating your lawn will dramatically change the color.  Consider the sunlight necessary for your yard when selecting the variety. Some varieties have better shade tolerance than others like After Midnight, Mazama and Everest.

Drought tolerant means a seed has been tested in trials against other varieties of the same species to show better drought tolerance than its peers. When a Kentucky Bluegrass variety says it is drought tolerant on the tech sheet, that means that it is more drought tolerant than other Kentucky Bluegrasses. That same Bluegrass may or may not be as drought tolerant when compared to a tall fescue variety by comparison.

Whether or not to use fertilizer depends on the quality of your soil. It may or may not be necessary, but as a seed company we recommend it, especially if starting a new lawn from seed. Starter fertilizer will help the overall success of a seed’s establishment.

A lime-like hue is typical of a lawn needing nutrients. Incorporating a nitrogen-based fertilizer with iron will dramatically improve the lawn. Other reasons for a lime color may also be too much water. Check to see if the ground is too wet and follow up with the fertilizer treatment. If fertilizer has no effect, you may want to test the soil.

Also, a lawn mixture that’s high in annual ryegrass will result in a more lime green color, and fertilizer will only temporarily hide it.

A purple hue to a lawn is typically the result of a phosphorus deficiency. Or it can be a sign of overfertilizing. Think about what you did or did not do and make adjustments.

If it’s over fertilizing, the lawn will typically grow out of it with time. Another reason for a purple hue is drought. Sometimes the plant responds to being watered after struggling from drought with a purplish color. 

An erosion blanket is always recommended. It will add a bit to cost to your project, but like insurance, it can save you a lot of money, too. Should a significant rainfall occur, it can save your lawn. It will also boost your germination results and reduce the amount you will have to water.

Grub issues are very difficult to diagnose until after the damage is done. They’re also hard to diagnose because once the larvae develop they fly away.

If you notice irregular drought issues in your yard, this could be an indicator of damaged roots. Dig up a few small hand shovel-sized areas and look in the top two inches of soil for any active larvae.

In Minnesota, grubs typically start in late May/early June.
