Sad news about my giant monstera… it became infested with thrips and I tried many things to get them under control but the plant really suffered. It went from giant healthy leaves and tons of new growth to brown and curled leaves with new growth immediately becoming infested and damaged. The plant started to look so ratty and unhealthy that I did kind of a drastic thing and dismantled it.
I attempted to use a pesticide spray for thrips but because the plant was so large it was difficult to actually make sure I sprayed every single surface of the leaves and stems, and areas must have been missed where the bugs continued to thrive because after several treatments the bugs were still there. It was also not great to spray inside the house as it could be harmful to our pets or daughter, and because the plant and pot were so massive and heavy it was really difficult to get it outside to treat fully. Eventually I just admitted defeat. Screw you, thrips!
Adult thrips are super tiny little black bugs that look like dots of dirt on the leaves, like in the first photo above. Young thrips are even harder to spot and are tiny yellowy dots that cluster on the leaves, especially on the underside. They suck moisture from the leaves leaving brown spots and other damage that you can see in the photos.
I cut the entire plant down to the dirt. Ahhhhh so sad!! I put all the stem pieces into water to propagate new leaves after I have cut away all the infested ones, so the plant will go on but it will take some time to recover.
The water propagation is already going well with the stems sprouting roots and new buds. The stems and roots that are still in the soil have also begun coming back and so far there are no signs of thrips still hanging out there. I even have a new leaf now, hopefully it will grow back in time and maybe reach its former glory 🖤
