Grass Seed Planting Tips
If your lawn is already established and you want to replace it and do not need to level, we suggest the following:
- Before you start you need to measure the area that you are planning on planting so you will know how much additives, fertilizer and seed you need. S ave your notes for this in a safe place for later use.
(length x width = square feet)
- It is best to get a soil test ahead of time so you know your soils' needs. This should be done one to two months ahead of time while you are planning your lawn. These tests take time to be completed which can give you time to gather the proper items that you will need for a successful planting. You can contact your local county extension office to find out where you can send these tests to be done. It is best to use the labs in your area for the best results. They need to be pulled from several locations in your lawn to be accurate. They should be pulled from the top 6-8" of soil to be correct.
- With the following options we are giving you the best control we had was using one of these options in the fall and actually waiting until early spring to replant your lawn. You should do one of the following options below and then move on to steps 4 and 5. After that if you are waiting until spring to plant, start off with step 6. If your temperatures have been in the mid 50's to 60's for 7 to 10 days a few times and your area to be planted shows no signs of weeds move on to step 7 about top coating and you will be ready to plant.
- Option One: This method should provide some excellent weed prevention when done properly on its own. Use peat moss, fine bark dust or potting soil at a depth of 2-4 inches over the top of your soil without mixing it in to the soil that is there. This will create a clean top layer to plant your seeds in and create a seal from your weedy top layer that you might have had. This option is more expensive but can work with good results. The fine saw dust is the least expensive of the three. Peat moss is more expensive and then potting soil is the most expensive.
- Option Two: You could consider the use of a herbicide that will kill the weeds for you. This method can be very effective and can be done in less time and cost less but you must be very careful and follow the directions on the label very carefully. If you choose to use herbicide spray the lawn with herbicide at least 3 days after regular mowing for best results. If you used the herbicide method wait the recommended time on the herbicide label and mow as short as possible. Remove the debris, you can save it as compost if you prefer. Then repeat process again with thatcher blade on mower, removing any excess debris. Or you could use strait apple vinegar that will control a lot of weeds.
- Option Three: One of the best ways to have effective weed control and the safest is to use sheets of clear plastic and cover the area you are working to kill and suffocate what is growing. This can be a little expensive and time consuming but will give you good control when done properly. The area needs to be covered completely for 6-8 weeks to kill some of those established harder to control grasses. After this time period has past remove the plastic and move to step 3 or on to step 6. Unfortunately, this does not work as well in the Northwest due to our cooler temperatures.

- When working the soil, be careful not to over work it if it is too wet. You could damage the soil by doing this and it takes a very long time to recover. A general rule of thumb is to pick up a handful of dirt and squeeze it in your hand, making a fist. Hold your hand straight out and drop the dirt on a firm surface. If it remains in a ball and does not break up, the ground needs to dry more before working. Loosen top 1" of soil using a cutter or tiller. There is no reason to go deeper.
- Rake and level removing heavier debris. You can use peat moss or sawdust on top of soil. (Make sure what you use is clean and does not have weed seeds in it.) Apply just enough to cover approx. 1/4". Level out with leaf rake. If lime or Gypson is needed this would be a good time to apply. If you can find a pellet or granular lime it is a lot easier to apply. Try to apply as even as possible. Use a fertilizer spreader to apply. It is best to apply these additives with a spreader of some kind for uniform coverage and to make a good planting medium.
- If you have problems with weeds in your lawn this is a good time to get better control on them. If you have the patience after you thatch, level and add additives start watering area to be planted. You need to keep moist for approximately two weeks. Do not water too much, when soil shows moist in morning and drying in afternoon you need to water again. Do not water excessively allowing pooling, this will drown the new seedlings of grass. If you do not have water let the area to be planted sit idle for 2-3 weeks. This will give weeds close to the surface a chance to grow.
- With 3rd option, after two weeks have passed you can repeat step 2 of covering with clear plastic again, this will control the new weeds that you have brought to the growing surface. The plastic will need to remain in place for another 2-4 weeks depending on how good of weed control you want. The longer time period the better. This should be done during the growing season to get effective control and needs to remain sealed to get good control. This method is hard to do because of the patience that are needed but you will be rewarded greatly which a beautiful clean lawn that will last longer.
- If you decide not to use the plastic try to rake of the weeds lightly with a leaf rake or pull out with a hoe or by hand. Try not to disturb the soil any more than you have to as when you do you will increase your chances of having more weeds grow again.

- If you use peat moss or sawdust you can apply them 1/2" deep over the area to be planted. This will help seal some of the weeds under the soil or sawdust applied if you have not done so previously. This will also aid in starting the new seed that you are going to plant and give them a fine growing medium for starting in. Level and smooth with a leaf rake and you are now ready to plant.

Planting Grass
Now it is time to seed your lawn after choosing the lawn mix of your choice. Using a fertilizer spreader at the designed setting, seed your lawn one direction back and forth using 1/2 the seed you planned on using. Now seed your lawn opposite or crossways using the remaining 1/2 of the seed. If you have a little seed left over save it for touch ups later. Now you are ready to water and let you lawn grow unless you want to touch it up lightly with leaf rake or a roller to firm down. The seed needs to be very shallow, basically on top of the soil. Seeds should not be deeper than the length of the seed. If you see seed lying on top you are ok. Remember that the rates we recommend are minimum and performance can be increased by using higher rates.
Watering
You need to keep your soil moist for the next 2-3 weeks. Re-water when soil looks dry on top in mornings. Do not allow water to pool or you could have dead spots. It is best to water for short periods when establishing, keep moisture on the upper level of the soil where the seed is planted. After the seedlings emerge you can start to reduce your watering and let the soil start to dry a little more so the roots will grow deeper in the soil as the plants get established.
New Lawns
For new lawns you need to get the soil leveled, smoothed out, and formed up to your preference. Make sure that you have good topsoil on the top of poor clay or rocky subsoil on top will prevent success. We would recommend watering your area the same as if it were planted for 2-3 weeks to get the weeds in the soil growing. Do not water excessively to create pooling. After this time let it dry off on top and decide which method works best for you above under 'PLANNING AND PREPARING FOR RENOVATING A LAWN'. After you have done one of the methods above you can top coat using less than 1/2" peat moss or sawdust. Make sure this topcoat is clean of weed seeds. This will give you a good seed bed fairly free of weeds and is very easy to use.
Repairing spots in established lawns
If you have a damaged spot in your lawn that you need to reestablish here is a suggestion on what we have found a successful method for reestablishing grass.
- Remove weeds or unwanted vegetation from area you need to patch
- Scratch area that you are going to seed with a hoe or garden rake at a depth not exceeding much more than an inch so the roots can grow in the soil
- Use potting soil, peat moss or fine sawdust and spread approximately 1 inch deep over the area to be repaired then rake and level. Do not mix with soil
- Use one of the seed mixes and apply seed with our easy to use shaker container
- Keep moist until established (best when done in the spring or fall)
Fertilizing your lawn
We use fertilizer at lower rates and apply a small amount each time to avoid fertilizer being washed away. We recommend waiting until your lawn is up and growing before you fertilize, (usually after the 1st or 2nd mowing). You need to follow the rates recommended on the fertilizer you use. What we have found for a growing an excellent lawn is to feed a little less and feed more often with fertilizer than to apply an excessive amount all at once, which could damage or kill your lawn. One of the easiest ways of avoiding problems and is a lot more safe is to use a slow release fertilizer. This will help your lawn stay greener for longer and is safer for the environment.
Lawns are like people in some ways - you eat more often than once a week and so does your lawn. The soil is like a kitchen, it can hold only so much food, and needs to be replenished during the growing season. When you mow your lawn, you take away nutrients. The more you mow, the more you take away and you need to replace.
Watering established
As your lawn becomes established it will need to be watered according to the weather. The warmer and dryer weather conditions, the more frequent between watering. Look around your lawn for dry looking spots. Some areas will dry out more often such as under trees or shallow soils. If you watch these dry areas they will guide you for how often you need to water. During the summer in the northwest a good rule of thumb is to fill a tuna fish can every week to ten days. What this means is put a tuna fish can under your sprinkler when you water and when it is almost full, that should be enough.
An established lawn likes a heavier soaking with drying in between to help prevent diseases. It is best to water at night or early mornings if you can. You will get the most out of your watering.
Lack of watering tends to make the grass look dry appearing and excess watering causes yellowing and tends to wash nutrients out of the soil. Excess watering will create more mowing and has a tendency to increase weed growth.
Mowing
The first time you mow it is best to let the grass become well established. You normally cut most of the grasses around 11/2" to 2" height. It is best to mow the lawn on a regular schedule according to growth. Normally you should cut 1/3 of the plant height. So when the grass is 3" cut back to 2". Letting grass grow to excessive heights and cutting them back short is hard on the plants and tends to shorten the life of the plants and causes unwanted stress, also poor color.
Cultural practices
- Keep the blades sharp on the mower to keep from bruising the cut edge of the leaves. (This keeps from bruising cut edges).
- Keep fertilized to keep "Dark Green", healthier and disease free. (Lack of nutrients can cause increased disease.) We recommend a smaller amount at a time.
- Mowing at closer intervals let you mulch clippings back into lawn. This is a healthy practice as long as it is done frequently otherwise you should remove clippings and compost them.
- Do not water excessively or it will cause washing out of nutrients, more frequent mowing and disease.
- Water good soaking approximately 1" or tuna fish can at a time enhances deeper rooting and a more drought tolerant lawn.
- Proper planting times are April, May and September through October in the Northwest.
Weeds
Weeds in an established lawn can sometimes be difficult to control, but once your lawn is established and cared for properly a lot of weeds will be controlled by the grass you planted smothering them out.
Broad leaves can be controlled with a weed and feed fertilizer at the recommended rates on the container or you can use a hoe to pull out the weeds if you choose not to use herbicides. Grass weeds are much harder to control than broad-leaves. The procedure we recommend for planting is a very good start to controlling a lot of these weeds by eliminating a lot of these weeds in the top growing area. However there are always some weeds in the ground that have hard seeds or are sometimes just dormant and escape controls. If you have problems with other grasses you can either spot spray or hoe out the unwanted plants.
Pests and disease
There are times when even the healthiest lawns are attacked by pests and diseases due to weather, soil and other conditions. If you have a particular problem send us an e-mail and we will try to help your recognize the problem.
We have found in recent years of field production, for example, that we have had a substantial increase in earthworm population in our soils. Because of the increase in worms, we now have a problem with moles, who have come into eat the worms, but have become a problem by making lots of holes all over our lawn. This is a sign of a healthy lawn but it does create a pesky pest that can be controlled. Slugs are another problem in the northwest; they have an appetite for grass. We have found over the years that our soils are healthier due to less chemicals being used and better crop rotations that help bring you better products
For over seeding a lawn for cool season grasses
When the temperature drops to cooler temperatures in the Southern areas it is the best time to over seed Bermuda grass lawns, in order to keep your lawn looking beautiful and green through the winter.
- For best results mow your lawn as close as possible to the ground or use a vertical cut machine. Rake and remove the debris. The debris removed would make an excellent compost.
- You can rent a thatcher or get a thatcher blade for your lawn mower. You need to loosen a thin layer of soil so the seeds can root in.
- Now you are ready to overseed your lawn. You should apply seed using 2-3 times more than the recommended new lawn-seeding rate. Seeding 1/2 the seed one direction and back and forth and the remaining 1/2 the opposite direction from that. You can use a broadcast spreader or a fertilizer to insure a more uniform coverage.
This project should be done when your warm season grass slows in growth or it will smother out the seed you planted. This is normally done in October and November in most areas. In the northwest the end of March through May would be a good time to overseed your lawn to improve the quality of it.
Dethatching
Dethatching a lawn is needed when you have excess debris built up, which prevents your lawn from growing properly by not allowing nutrients to get through to the soil. In extreme cases your lawn will almost die out from the thick mats of dead roots, clippings and debris. You need to thatch and remove this debris. The best time to do this is fall or spring when plants are slowing in growth. This will also improve the health of your lawn.
Aerating
In some areas you tend to have high traffic. That will tend to compact soils not allowing water and nutrients to get to the roots. Old lawns with very little care that have been in a long time have more problems with this because the old root mass is built up throughout the lawn. If you are replacing a new lawn or OVER SEEDING it would help insure success of your new lawn to aerate before replanting. You can rent these machines if needed from rental places.
Debris
You need to make sure not to leave debris that covers the top blades of grass in your lawn. Whether it is leaves, needles grass clippings or other debris, if left lying thick enough will block light from reaching the plants and will damage or kill spots in your lawn.
Shade
If you have shady areas such as under trees you might need to get a different mix to seed those areas to achieve a successful lawn. Trees and lawns tend to fight for moisture and nutrients also. Depending on the size and type of tree, those areas might need a little extra care to stay in top shape.
A last word
In some areas like in the Northwest, to keep a top notch premium lawn you need to overseed or kill out and start over every 3-5 years depending on how well you maintain your lawn, some will last longer. In the southern climates they will need to be over seeded every year.
Timing on seeding lawns and controlling weeds is important. The growths of these two items are controlled by temperature. The debris such as clippings, leaves and roots from these projects work really well for composting for your garden or flower beds. When composted properly they can make an excellent amendment to your soil.
We realize there is a lot of work caring for your lawn, but it will give you satisfaction for a very low cost and a lot cheaper than spending extra money paying to exercise somewhere and a lot more rewarding doing something that really shows. Remember you are also helping the environment by producing oxygen, filtering the earth and staying home instead of driving a car that causes pollution. You are putting something back instead of taking something. Think about it!
