Hello! I hope it's ok to post questions like that here. I have ALWAYS had problems with Monsteras and their leaves browning and dying off. I always thought it might be a too dark or too sunny location. Now I've made some new living room space and I thought maaaybe this spot would be good (bit away from a large window, lots of light but no direct sunlight hits it)

But once again the leaves turn brown, just as they did with the regular Monsteras I had. I tried spraying them with water for humidity, but no help.

So now I wanna ask if anyone has an idea what could cause this? If there might be something I'm obviously doing wrong?

Any help would be greatly appreciated <3 ๐ŸŒฟ

I think adding liquid potassium silicate to your watering routine (0.5ml-1 tablespoon per gallon) every 1โ€“2 weeks to strengthen cell walls and prevent heat/drought stress. It is particularly effective for reducing browning on variegated plants (like Thai Constellations) by fostering thicker, healthier leaves.

How to Use Silica for Plant Care: Watering Additive: Mix liquid silica into your water first, letting it sit for 10โ€“20 minutes, before adding fertilizer.

Foliar Spray: Lightly mist leaves with a silica-water mixture 1โ€“2 times per week for faster uptake. Soil Amendment: Mix solid forms like diatomaceous earth or rice hulls directly into the soil to improve long-term nutrient availability. Dosage: Use a lower concentration (e.g., 0.5 ml per gallon) frequently (every watering) rather than high doses to avoid nutrient lockout or fertilizer burn.

Benefits of Silica: Reduces Browning: Strengthens cell walls, preventing, for example, the browning of new variegated leaves, says this TikTok video. Increases Resilience: Improves resistance to heat, drought, and pests. Better Metabolism: Increases nutrient absorption, leading to stronger, more structured foliage.

Note: Silica is not mobile within the plant, so regular application is necessary to protect new growth.
