Rock vs. Mulch
- Long lasting- stone will not have to be replaced over time
- Cost- while the initial cost is higher than mulch it’s a one time expense and you won’t have to add to it each year
- Fire proof- rock is not a flammable material and can be a good option for areas near a fire pit
- Durability- rock isn’t going to be affected by the elements and it will withstand more wear and tear than mulch
- Drainage- if your property has drainage issues stones will not hold water
- Soil temperature- rock will hold heat and raise the temperature of the soil in the summer, this can cause stress and dehydration for plants
- Nutrients- since rock won’t decompose there isn’t a nutritional benefit to using it, it also causes soil to be more alkaline while most trees prefer acidic soil
- Flexibility- rocks are heavy and difficult to move so they aren’t a great option if you’re wanting to plant annuals or if you think you might want to rearrange plants at a later date
When is Rock the Right Option: Rock is a good choice to go around buildings, decks, pools, and fire pits. If you decide to use rock around plants it’s best to stick to heat-resistant shrubs and trees that you plan to keep in the same spot for many years to come.
- Moisture- mulch retains water and helps plants stay hydrated, studies have found that wood chips held up to 3 1/2 inches of water per foot of mulch
- Cost- the initial cost for mulch is much less than stone
- Flexibility- if you enjoy planting annuals or if you think you may want to move plants around at a later date mulch can be moved around easily
- Plant health- when mulch decomposes it puts nutrients back into the soil, it helps insulate against temperature changes and studies have shown it can nearly double the rate of tree growth
- Weeds- mulch reduces weed growth and germination
- Soil erosion- mulch naturally helps prevent soil erosion
- Maintenance- mulch needs to be freshened up each year because heavy rain or wind can remove pieces
- Flammable- mulch isn’t a great option near fire rings or outdoor BBQ areas because of its flammable properties
- Fading- over time the color will fade from sun and exposure to the elements, this is another reason why mulch has to be periodically replaced
When is Mulch the Right Option- If you want a material that is more affordable initially and you enjoy planting annuals each year mulch might be a good choice. Mulch provides a lot of flexibility if you want to be able to move plants around or try something different periodically.
