Lawn Care

Partsman41953(8)March 20, 2013


I live just outside Columbia, SC. I have a slopped lawn which stays soft most of the time and only gets partial sunlight most of the day. My other problem is that the swale stays moist most of the time as well and I have a difficult time growing grass there. I am not sure what type of grass I have but I do know that my lawn is full of poa annua. What should I do to try and grow a healthy lawn? I do have a couple of small trees in my front lawn which does keep some sunlight off my lawn at times during the day.

I am open to any suggestions.

Can you post a picture showing the shade?

How often do you water and for how long?

How high/low do you mow?

Right now with no leaves on the trees the yard is getting sun most of the day but during the summer where the 2 small trees are the area that stays soft I would estimate only gets sun for about 4-5 hours a day.

I only water maybe 2-3 times a week as the area by the swale stays soft and moist most of the time.

To answer your question about mowing, I have a brand new Toro mower that was set up on the medium cutting height and I have not changed it.

I hope that answers your questions.

Watering is your problem. This time of year you should be watering no more than once per month. When you water it should be a full inch all at one time. Measure with tuna or cat food cans. Your soil will become very firm (hard) by the time you water again. This is normal. Wet and soft all the time is the reason weeds sprout. You should increase the frequency slowly through the spring until in the hottest heat of summer you are watering once every 7 days. During very hot and dry periods, you might go to once every 5 days. By watering like this you discourage the weed seeds from sprouting. They need continual moisture like they are getting now. Established grass gets moisture from deep roots. When you water deeply, then the grass can get that moisture for many days on end without needing to be refreshed.

Sounds like you have too much shade to grow most grasses. Your two choices would be fescue or St Augustine. I would ask around with the neighbors to see what they have. Bermuda and Kentucky bluegrass would be out of the question. Most zoysias will not grow in that much shade, either.
