The first plant I brought in the house and transferred to leca, a Monstera. Seems to be doing well, but it’s developed gnats. I put some sticky traps around the base of the plant, and I crumbled some mosquito dunks into the cache pot. I’m thinking maybe didn’t clean enough of the organic matter off the roots. Should I repot, clean all the leca and roots and start over? Should I just do cuttings with what I have and restart with no roots? Also read about adding Death Drops to the water. Should I add this to the water and water from the top letting it drain into cache pot? Any thoughts about this or other suggestions would be appreciated.
