Unless you want to patiently dig up every bit of crabgrass on your lawn ( and are prepared to get down digging all over again as before long as you ’ve finished ) , then the best way to toss off crabgrass in a Bermuda lawn is by using a very selective green goddess killer .
Step 1
Purchase a army tank - type atomiser . A 2 - gallon sprayer should be large enough for most nursing home weed problems .

Step 6
Water your lawn thoroughly after the weedkiller has had at least 24 hours to work its way through the leave of absence and into the roots . Keep your lawn dampness , but not soak wet , for seven day . Then , spray your K a 2d clip with the crab grass - selective weedkiller , mixing it per the manufacturer ’s statement .
