Yesterday we started a two day yard-overhaul with the addition of fresh black mulch bark for a new weekly service client of ours.
Does your landscaper remove the prior year’s mulch bark before adding a new layer to your yard? Well, they should.
Here is why:
If you're applying mulch bark to a perennial bed, one might be tempted to just add a new layer of mulch bark on top of last year’s application. It is unfortunately a mistake commonly made by our landscape experts here in the Sacramento and El Dorado Counties. The problem is when we add layer after layer, season after season of mulch bark we do harmful things to our yard’s beds. By not removing last year’s mulch bark application we will see the cause of rot, nutrient starvation, and plant death.
Too much mulch bark ends up piled around a tree trunks and bases of plants, resulting in bark and branch decay, fungal diseases, rodent infestations and roots growing in the mulch bark rather than the soil (just to name a few adverse effects). If more than four inches of mulch is used, it can end up repelling water and thick layers of mulch bark can also prevent air from reaching the roots, suffocating the plant. Ensure your landscaper removes as much of the old mulch bark layers as possible before you add more this year.
As an FYI though, this will be an additional cost you may have not seen in the past on the estimate and invoice (time to remove the top layers of last year’s mulch bark, transport costs to the Sacramento Dump and the associated dump fees). To stay competitive and out price the other landscaper, most to not offer this needed step. They are doing a disservice to our yards in doing so unfortunately.
Ask your landscaper if they offer this must-have service. If they don’t, kindly suggest they should, educate them and reference this helpful article written a few weeks ago on TotalLandscapeCare.com https://www.totallandscapecare.com/business-best-practices/proper-mulching-techniques-for-landscapers/
All the best to you and a great yard!
