When I purchased this dieffenbachia tropic Marianne, there were already a few leaves browning so I didn’t water it until 2 weeks after I got it cause I wasn’t sure of the state it was in. Parts of leaves all over were also starting to brown so I just trimmed (prune?) to start fresh but now there’s little patches of brown growing in again but still new growth (so cool - now I get the excitement!). I am not sure what to do with the browning that comes in often? My main reason for cutting off the browning was because it started bringing in tiny mosquitoes or flies. I water every 2 weeks, not much sunlight where it’s placed and use miracle grow every 2ish-3 weeks (taking turns with watering). I also use tap water because that’s what is available in my office. Not sure if that should change. 😬 #dieffenbachia

Oh it’s also still in a plastic pot sitting on a plate… I will be getting a pots this week.
1ft to light, indirect

Browning is usually due to too much dryness/lack of watering, yellow leaves from over watering. I’d check the soil - if it’s dry an inch or 2 down in the pot, time to water!
Yeah, the new growth is what hooked me, too :)
What’s your humidity like?
@dylan1stokes humidity isn’t great… it’s in an office 😅 heat is usually 67-70 degrees
@Jenstolt85 thank you! I’m still pretty new to all of this. Would a moisture meter be helpful?
@SensuousSalal dieffenbachias like high humidity, so maybe this has something to do with it🤷🏽‍♂️
Browning bits on the leaves themselves won’t bring in what I’m assuming are fungus knats, it’s damp soil and high organics/fertilizers. If your plant is growing well and not showing any signs of nutrient excess, than I’d suggest that you focus on letting the soil dry out more in between waterings. I’d even go so far as to recommend that you push the length between waterings to the point where the plant starts to droop a little bit and that will you give you a better gauge of how long it actually takes for your particular soil to dry out and what the soil looks/feels/weighs when it’s that dry. From there you would want to water a few days before drooping occurs, gauging this by the soil characteristics mentioned before. Don’t water by a schedule though, get in there and really figure out how moist/dry that soil is. It can be difficult though, so a moisture meter can help. Just be a bit wary of relying too heavily on them as they can be inaccurate for a variety of reasons, but I find the most problems with them occur when they’re used in soils that have a high perlite or other inert material %.
Another note: that method of waiting until droop will not work for all types of plants, some it may be harmful to, but Dieffenbachia are actually fairly drought resistant (it’s those thick, caney stems!) and will perk right back up from a slight droop. I hope that was helpful and good luck! Your plant still looks great, so I’m confident you’ll be able to turn those issues around :)
I find that dieffenbachia are temperamental. In the winter I only feed once a week. I would cut off dead leafs.
@JessaBurra thanks so much!! I will definitely have to consider this drying out between watering because it might’ve been overwatered when I recovered it then. It’s doing a lot better. Dropping a bit but I tried to move it to a more indirect sunlight corner
