A 5-foot saguaro was stabbed in ~50 places with a rusty spike. After recent rains, the plant is rotting and oozing black fluid. The owner, who paid $500, wants to know if it can be saved.
Greg states that black ooze usually means the plant will not survive. Scooping out rotted tissue and letting it heal is an option, but the damage is likely too extensive, and the recent rain will accelerate decay. The plant's appearance will be severely marred even if it lives.
Greg suggests checking Craigslist for larger saguaros at lower cost (though transport/planting is DIY). For similar stature with faster growth and lower price, he recommends Trichocereus terscheckii or Neocardenasia herzogiana, which are common in Arizona nurseries.
Once a saguaro shows systemic black rot from penetrating wounds, recovery is unlikely. Consider replacement with a more vigorous, affordable columnar cactus.
