Seed Starting


For best results use a lightweight, soilless growing medium for unrestricted root growth and drainage (not potting mix).

Peat pellets and pots help to reduce root shock and damage when transplanting to larger containers or into the ground.

Read the germination instructions on/in your seed packs for specific heat and light requirements.

Label your trays and pots right away when planting different types/varieties to prevent any mix-ups.

Helpful Tips

You should be planting your grass in at least 3" of good top soil which we sell by the bag or cubic yard (picked up or delivered) if your soil is too shallow.

The pH of your soil is also very important. We offer a soil testing service, or you can buy a simple kit if you wish to do the test yourself.

Starter fertilizer is very important and will help you improve your rate of successful germination. The high Phosphate level helps your roots grow deep.

Watering is a must. Put an empty cat food or tuna can 10 feet from your sprinkler and see how long it takes the can to fill with an inch of water. Repeat watering for this duration every 2-3 days (more frequently when very hot). Early mornings are the best time to water.

To grow grass successfully, you need a minimum of 4 hours of sun for Dense Shade mixes. Sun & Shade mixes will need 6-10 hours of sun. If you get 10-15 hours of sun, you will want a Sunny mix.

Tall Turf Type Fescues grow a deeper root system to be able to survive a drought longer. You need lots of water to start.

If you are over seeding, use half the rate when applying. If your lawn is 10000 sqft. and is already covered in grass, a 5000 sqft. bag will do the whole area.

Here we are using Grodan "grow cubes" surrounding an "A-OK" starter plug. The tomato plant was started from seed and transplanted into a 3" net pot. The "grow cubes" provide the necessary air pockets and provide moisture retention. Just add water with any of our Foxfarm or Hydrofarm liquid concentrated formulas.
