Do you replace your mulch every season?

Personally I always just added to it. To replace what got "lost" from last year. I'm not sure about benefits of replacing it...I think adding is sufficient, at least for me.

Mulch should be replaced yearly as many deadly incects etc make a home there. These bugs can cause some diseases to spread into plants flowers etc. I change my muclch every season to avoid the bugs. It's a personal decision. But beware bug beds. During the warming time the moisture builds up under the mulch making it very attractive for many types of incects both good and bad. Most thrive under thse moist warm conditions. So go with whatever you're comfortable with.

The broken down material is added to the soil. It is a good idea to just add to it. Have you ever seen the soil in the forest. very year the leaves are piled on top of last years and it is some of the richest soil you can come across. If you do decide to remove it, be sure to add it to the compost pile!!

Ours just seems to disappear... blows away, sink into the soil.. not sure where it goes, lol. I like putting mulch around my plants in the spring because it looks nicer.

All my flowerbeds are perennials so once I plant them, I don't touch them at all until they get crowded and I have to dig them up to divide. Between times, I just keep adding mulch every fall and sometimes in the spring if needed. Have yet to water any of my flowerbeds or pull weeds cause the thick layer of mulch (grass clippings, leaves) keeps the weeds at bay and prevents the moisture from evaporating. When I do have to dig them up, that's when I spread a ton of aged horse/cow manure on top of the mulch and till it all under b4 replanting the divided plants and adding more mulch to start the process all over again. Strictly organic gardener who always discovers new ways to save gardening time. lol

I simply add to my mulch each spring. It seems that quite a bit of it disappears over the winter months, so I put new mulch back on top.
