I’m new to plants and these three are having some issues! I think I might be over watering them but I’m not too sure! If I am, how often should I be watering a dragon tree, money tree and arrowhead plant? I have attached pictures and any help would be much appreciated! All plants have been kept on the windowsill of a south facing window! Dragon tree: I’ve been watering this guy about every 9 days.. it’s stem is kinda soft and it’s bottom leaves are turning yellow and falling off! Also it has roots coming out of the drainage holes, should I repot it? Money tree: this one gets water once a week! my money tree has new growth but it’s larger leaves are getting large brown spots and the leaves are drooping! Arrowhead plant: and this one gets water about every week too! this guys leaves are looking bleached and droopy but it still has new growth so I’m confused! ANY HELP IS APPRECIATED!
They all sit on a windowsill that is south facing! It doesn’t get direct sunlight and is pretty dim! I’ve attached a photo of the window for reference.. the picture was taken at 2:40! Hope that helps
Your watering is probably ~OK. Your light is pretty marginal, and these plants will "live", so to speak, but decline over time. The eldest leaves (most interior/closest to the trunk/crown) will die and new leaves will grow out of the crown, but growth will be slower than normal and the lifespan of the leaves will be shorter than normal. Feeding with a liquid fertilizer during the growing season would probably help make the color a little darker green, but, that's a double-edged sword. Growth is a product of the sum of the conditions: light, water, fertilizer, air, soil, and pestilence. You can't make up for a shortage in one component by increasing another component: increasing fertilizer won't offset a shortage of light. In fact, increasing fertilizer beyond modest would probably just increase the length of the stems reaching for light that isn't forthcoming giving you plants that would be more spindly. We become invested with the plants we acquire, and most people have qualms about throwing a plant away. You might look over your charges and ask which of them you are willing to baby for what length of time for them to continue growing... just the same, a year, five years, etc., etc. If you decide to throw some overboard, it's easier than you may think. On the day before trash day, put it on the curb so passers-by can see they are abandoned. I almost guarantee that someone will carry it away to a new home. (Do it on a dark day so the don't sunburn too bad) Then, you can shop around for replacements that are specifically low light tolerant. Dumbcane, Cast Iron, Coffee Arabica and others that people here will suggest.
