Is it better to overseed in the spring or fall?

Fall is the best choice. The soil is still warm which means the seed will germinate faster. Also, weed growth tapers off after summer, so your new grass won't have to compete for sunshine, water, and nutrients. Overseeding in spring is the next-best option.

Can I just throw grass seed down on existing lawn?

Should I overseed more than once?

Is your lawn thin, full of crabgrass and other annual weeds, or damaged by insects such as white grubs or chinch bugs? If the answer is yes, then repetitive overseeding can help. Repetitive overseeding is an easy method to make existing lawns more dense by simply sowing more seed .

Can you sprinkle grass seed on top of soil?

Will grass seed germinate on top of the soil? Yes; in fact, germination will suffer if too much soil is placed on top of the seeds. The experts at Jonathan Green recommend placing a thin layer of mulch or topsoil over them to help keep them moist and warm and promote growth.

Should I put topsoil over grass seed?

Do not put top soil over grass seed, but you can add a thin layer of organic matter to help the seed to germinate. 'Never put topsoil over newly planted grass seed,' says Yamaguchi.

Does overseeding actually work?

THE BENEFITS OF OVERSEEDING

Overseeding newer turfgrass varieties into an older lawn can help it better withstand insects, disease, drought, shady conditions and heavy traffic. The investment in overseeding pays off by reducing the amount of fertilizer, water and pesticides required.

Should I pick up plugs after aerating?
