I must not have been very clear. Buffalo grass is a native grass in my area. It is mixed in with other grasses in pastures and prairie throughout the natural landscape. As our lot currently stands, the weeds (mostly tumbleweeds) have taken over any good prairie grass that is there. We are not planting the 3 acres to lawn, we are planting buffalo grass, which is something we can keep maintained, is native and does not need watered. We are planting over 150 trees and shrubs and plan on introducing a variety of planting beds throughout the property with native wildflowers and ornamental grasses. I feel like we are improving our landscape in a very responsible way and am simply asking for help doing this correctly. Our lot is across from a golf course and although it is in the country (our lot backs a pasture for grazing cattle and circle of corn) it does have to have the look of a manicured area. I frankly feel that people in this area are very good at removing invasive, although "native" weeds that cause a nuisance not only in the way the look but in the amount of water they suck from the ground, and therefore taking over the native grasses. People here plant buffalo grass, keep it mowed and don't water it, which is what we would like to do. Thank you all for your help.

Maybe Senecio vulgaris, common groundsel??? If so, pretty early for bloom although it is a spring bloomer. Can be tough to control as it has developed resistance to many products. Contact your local extension service for the right treatment. hortster Here is a link that might be useful: common groundsel

Hello - I am in Twin Cities of Minnesota - Zone 4. I overseed with a mix of perenial ryegrass, fescue and KBG every year, Since I am in MN not much watering in March and April. :) but I do have an irrigation system so it never gets dried out in the summer months.
