    Hey guys,
    I got a phone call from a guy who has a 'lumpy' lawn. he says it's been getting worse for the last few years. Anyone know what's causing it?
    I haven't seen it yet, but I'm thinking it may be from a cut-down tree that's roots are decomposing slowly.
    Any suggestions or advice would be appreciated.

    Thanks in advance,

    maybe the builder of the house burried trees and wood and it is now starting to decompose. How old is the house?

    TheKingNJ, thats what I was thinking. I've got a customer that has that, and about everywhere it sinks a few feet. Almost time to do some serious digging.

    Up here we have really big earthworms called Dew worms that cause the lawn to go lumpy. I know there is a chemical application you can use but it poisons the worms and if the birds get them, it poisons them too. I tell my customers to live with it. Aerating in spring and fall seems to help a bit as does topdressing (evens out the low spots). Don't know if this helps.
    This is from one of the local garden centers (goldenacregarden.com)

    Dew Worms create small mounds in your lawn, making it uneven. Some dew worms are beneficial as they prevent the ground from compacting. If you are overrun with them, apply carbolic at the recommended rate (mixing it with water), using a watering can to prevent chemical drift. Water your lawn and surrounding area thoroughly for 1-2 hours in the early evening, then apply the chemical. Remember to read the directions first before you apply the carbolic soap. Remove any dead worms seen, as they are poisonous to birds. Repeat this treatment several times at 2 week intervals and have your neighbors treat their lawns as well to lessen the chance of recurrence. This is only a temporary solution; the best method is to live with them and use gypsum to break down clumps and mounds left by dew worms.

    What does he mean by lumpy? I took over a few lawns that appeared to be lumpy, in being that there were alot of mixed in bare spots, etc., that made the grass not appear to be full at all, just really choppy. Does he mean the lawn itself or the ground?

    This is what we expierence in our area too. I wont treat them with a chemical application as they are beneficial to the soil.

    Those lumps should actually be a sign of healthy soil, and healthy soil grow greener lawns, right?
