2023年7月5日 · If infested material is used for mulch, the artillery fungus may be already in the mulch when the load of mulch arrives at a job site, and may then grow rapidly along your foundation during cool moist conditions.

2022年10月19日 · There is some suggestion that artillery fungus in mulch such as cedar and pine bark nuggets may occur less frequently than hardwood. It is most prevalent on the north side of a building and shoots spores towards bright light. This fungus produces a cup-shaped peridiole which contains fruiting bodies.

The fungus grows on dung and well-rotted wood such as the wood chips used as foundation bed mulches. It prefers open areas with little shade and sufficient moisture. With sufficient light, the optimum temperature range for the production of fruiting bodies is 10-20 degrees centigrade.

Growth of artillery fungus is favored by hardwoods in mulch, excessive rainfall, or irrigation of foundation plantings. Artillery fungus is problematic on north sides of buildings where shade maintains moist conditions.

2021年8月6日 · If you happen to spot some artillery spores in the mulch you just brought home, don’t ignore it. You can remove it by covering it with plastic to suffocate it and then dig it out and remove it. You could also rake the mulch out into a thinner layer so it will dry out quickly and prevent the spores from spreading.
