Answer: It does take persistence to combat dandelions. Attack when they are weak, which means weeding with a vengeance whenever you see them emerging, removing as much of the root as possible. If the weeds have already gone to seed, mow and remove the clippings to prevent reseeding. A healthy lawn is a deterrent to dandelions because they prefer thin turf. Also, mowing with the blade set high will allow the grass to shade the low-growing weeds and slow the germination of weed seeds. To achieve a thick, lush lawn, put your turf on a regular feeding and watering schedule; fertilize in April, June, September and November (check your local garden center for specials on fertilizers - they typically go on sale at just the right time for application in your growing region).
Best wishes with your new home and your new landscape!
