My lawn has a fair amount of weeds among the grass. I've been concerned about using my mulching mower and leaving the grass clippings because I'm also leaving the weed clippings. Won't this just spread the weeds?
regards

Maybe, maybe not.  There are a lot of factors to consider.  Have the weeds set seed?  If so, then potentially.  If not, then no way.  More importantly, using a mulching mower may spread seeds, but the healthier soil that will result from mulching will be more likely to promote the growth of fussier plants such as your grass, helping to out-compete the weeds, and the mulch itself if it is thick enough can suppress weed growth by blocking sunlight from reaching the soil.  Weeds are pioneer species that succeed by quickly filling in empty spaces in the soil and are not adversely affected by low nutrient content the way other plants are.  Fill in those spaces with healthy grass using mulching along with all the other strategies used to build soil, and the weed problem will diminish over time.  Probably won't go away completely without a lot of care, assuming an organic strategy, but it will diminish.  It is important to note that there are always so many weed seeds already buried in the soil just below the surface just waiting for a chance to germinate that spreading a few around with a mower probably makes very little difference.

unless you are super particular about an immaculate lawn of no weeds..allow the weeds to grow in your lawn.

they are super good for the lawn, i have clover that grows in mine and it provides nitrogen for the soil and grass..i have yarrow, daisy, dandilions, plantain also that grow in mine and all are edible or used for tea..

some day you might wish that you had left these to eat..they are yummo.

eat them in early spring and then just mow them the rest of the year.

Thanks for the advice. I'll probably mulch but don't plan to make tea from my lawn.
