Landfill regulations against the disposal of yard waste have increased substantially over the last several years, resulting in a large surplus of bark mulch. Realizing the ongoing popularity of bark as a landscape enhancement, entrepreneurial minded individuals are springing up everywhere to offer bark mulch for sale. Naturally this means price competition for bark mulch in Port Orchard, which makes for a great opportunity to get some landscaping done on the cheap, right? Maybe. But then again, not so much.
Improperly stored bark mulch is prone to becoming “sour mulch” which can severely damage or even kill your plants and trees. According to studies dating back to 1966, stored bark has been known to develop low pH levels which leads to dangerous anaerobic by-products such as methane, alcohol, ammonia and hydrogen sulfide. Traditionally, sour mulch has been a somewhat rare problem since it is alleviated by increased oxygen levels associated with the frequent moving of the piles. In the past, the piles were “disturbed” often enough when a load of bark was sold to assure healthy aeration. But experts worry that this will no longer be the case. Larger piles and longer storage times due to supplies outrunning demand point to greater opportunity for bark piles to become toxic.
So how do homeowners and businesses avoid the grief of having their prized plants and shrubs burned to death by bark they intend to protect and enhance their property? While no one is immune, the safest way to get healthy bark in Port Orchard is to buy from a proven landscape dealer. For example, Randles Sand & Gravel, has a huge customer base which translates into constant inventory turnover and thus there is little chance of their bark breaking bad.

A second tip: your nose will know. Before spreading the mulch, reach into the pile and grab a handful and take a whiff. If you catch the scent of vinegar or ammonia know that you indeed have some sour mulch. But all is not lost. Spreading the pile out on a protected surface such as a tarp or driveway and allowing it to air out for three to seven days will bring the pH levels back into safe ranges in almost all cases.
