n Step 6 : Treat your soil with high-quality calcium . Organic lawns grown in this part of the country will almost always benefit from an autumn dose of calcium , which in time will help eliminate the most common and obvious weeds . Ap-
organisms while spreading weed seeds . What to do : Drag your rake across the lawn with just enough pressure to pull the leaves away .
n Step 10 : Aerate high-traffic areas . High-traffic areas — usually patches by the driveway and walkway near the road — are prone to common plantain weeds , which
rejuvenate your lawn before the frost sets in , and grass seeds will outcompete weed seeds . This is the one time of year when an aggressive raking can help , just prior to overseeding . The raking helps loosen the soil to get better seedto-soil contact . Be sure to water daily until the seed germinates .
plying lime is one way , but make sure it ’ s the right type . Dolomitic limestone , the most common type , is high in magnesium but fairly low in calcium . Instead use calcitic limestone , which has enough calcium — and use pellets rather than powder to keep potentially harmful dust to a minimum . If the soil test shows that your soil is alkaline — with a pH over 7 — use gypsum instead of lime because gypsum won ’ t affect the soil ’ s pH . As with limestone , pellets are better for most lawns .

Although the entire lawn can benefit from aeration , it is especially useful for these high-traffic areas . You can rent a “ core aerator ” ( with hollow spikes that remove cores of soil rather than solid spikes that only poke holes ) at a hardware store for about $ 35 to $ 90 by the day . Core aerators require more exertion to operate than lawn mowers — if you ’ d rather not tackle
n Step 12 : Top-dress your lawn with compost . This step can be costly , but top-dressing your lawn with compost in the fall is probably the single best thing you can do . Although it looks like black dirt , compost isn ’ t soil . It is decomposed organic matter that serves several critical functions including adding nutrients . Order a bulk delivery from a nearby compost manufacturer or your municipality . Montgomery County ’ s own Leafgro is an excellent bagged source found in most of the County ’ s garden centers .
