I have two plants. One was turning dark brown on the edges. That would undoubtedly be from over-watering. The water meter read dry all around and moist in the middle. Water meters don't measure moisture, they measure electrical conductivity. Fill a clean cup part full of distilled water, insert a clean water meter probe and note it reads 'DRY'. Sprinkle some salt in the water (makes the water conduct electricity) and watch the meter move to 'WET'. It's much better to use a 'tell'. See below. I soaked it and the nursery said to take take it out if the pot and ket the rootball dry out. After I did that, I repotted and soak it. The advice to remove the root/soil mass was to pull the excess water out of it. Putting it back in the pot and soaking it undid what would have otherwise been beneficial. I also cut the brown off of the edges. No problem in doing that. You should find this piece about Good Growing Habits helpful. The shortest route to green thumb status starts with learning all you can, instead of trying dozens of different things and ending up totally confused by the mixed results. When you learn what to do beforehand, you don't spend your valuable time getting bit on the butt by mistakes; rather you use your practical experience to validate what you already learned. Practice that, and you'll leave the 'trial-and-error crowd' standing in your slipstream. Using a 'tell' Over-watering saps vitality and is one of the most common plant assassins, so learning to avoid it is worth the small effort. Plants make and store their own energy source – photosynthate - (sugar/glucose). Functioning roots need energy to drive their metabolic processes, and in order to get it, they use oxygen to burn (oxidize) their food. From this, we can see that terrestrial plants need plenty of air (oxygen) in the soil to drive root function. Many off-the-shelf soils hold too much water and not enough air to support the kind of root health most growers would like to see; and, a healthy root system is a prerequisite to a healthy plant. Watering in small sips leads to avoid over-watering leads to a residual build-up of dissolved solids (salts) in the soil from tapwater and fertilizer solutions, which limits a plant's ability to absorb water – so watering in sips simply moves us to the other horn of a dilemma. It creates another problem that requires resolution. Better, would be to simply adopt a soil that drains well enough to allow watering to beyond the saturation point, so we're flushing the soil of accumulating dissolved solids whenever we water; this, w/o the plant being forced to pay a tax in the form of reduced vitality, due to prolong periods of soil saturation. Sometimes, though, that's not a course we can immediately steer, which makes controlling how often we water a very important factor. In many cases, we can judge whether or not a planting needs watering by hefting the pot. This is especially true if the pot is made from light material, like plastic, but doesn't work (as) well when the pot is made from heavier material, like clay, or when the size/weight of the pot precludes grabbing it with one hand to judge its weight and gauge the need for water. The advice to water when the top inch or two of the soil is dry is almost always counter-productive. Fingers stuck an inch or two into the soil work ok for shallow pots, but not for deep pots. Deep pots might have 3 or more inches of soil that feels totally dry, while the lower several inches of the soil is 100% saturated. Obviously, the lack of oxygen in the root zone situation can wreak havoc with root health and cause loss of a very notable measure of your plant's potential. Inexpensive watering meters don't even measure moisture levels, they measure electrical conductivity. Clean the tip and insert it into a cup of distilled water and witness the fact it reads 'DRY'. One of the most reliable methods of checking a planting's need for water is using a 'tell'. You can use a bamboo skewer in a pinch, but a wooden dowel rod of about 5/16” (75-85mm) would work better. They usually come 48” (120cm) long and can usually be cut in half and serve as a pair. Sharpen all 4 ends in a pencil sharpener and slightly blunt the tip so it's about the diameter of the head on a straight pin. Push the wooden tell deep into the soil. Don't worry, it won't harm the root system. If the plant is quite root-bound, you might need to try several places until you find one where you can push it all the way to the pot's bottom. Leave it a few seconds, then withdraw it and inspect the tip for moisture. For most plantings, withhold water until the tell comes out dry or nearly so. If you see signs of wilting, adjust the interval between waterings so drought stress isn't a recurring issue. Al

If you clean the tip of your moisture meter and dip it in a cup of distilled water, the meter will tell you the water is dry; this because the meter actually measures electrical conductivity. So if you have a given volume of water in a given soil, the higher the TDS (total dissolved solids or roughly - salts) the wetter the moisture meter will tell you the soil is. A wooden dowel, used as a 'tell' is more reliable. If I do heavy root work on tropicals, I habitually reduce the canopy by a very large fraction to keep the plant from A) collapsing, or B) from shedding branches that might be an important part of the composition I'm building. Example: From this root mass to this:You can see the huge roots I severed, and that was only the first rootwork session. Since then, I've pruned the root mass back to just about even with the soil level in the image below. We actually have a tool designed specifically for this chore, called (what else?) a root cutter. The tree is F benjamina. The foliage mass, on the same day, went from this: To this: I'm not sure what this means: There is no other location that's suitable for this big tree. Given this condition, should I supplement the lack of light with the Dyna-Gro in a month or so? You can't counter or remedy a lack of light by supplying fertilizer. In fact, you need to be careful about not over-fertilizing in low light conditions. Dyna-Gro's Foliage-Pro 9-3-6 is a good choice for low light conditions though, because it's nitrogen sources tend to reduce likelihood of the coarse growth that occurs when using fertilizers that get their N from urea.

Your plants' issues, relative to the spoiled foliage, are most likely related to over-watering, a high level of dissolved solids (salts) in the soil solution, or an ammonium toxicity that develops when roots are asked to live in saturated soils. I'd suggest that you start using a 'tell' to determine when your plants actually NEED water, and only then supply it. A 5/16" wooden dowel rod, ends sharpened in a pencil sharpener, makes a good 'tell. Read more below, and please forgive the formatting. It's from something I wrote and saved. The leaf shedding can be from a decrease in light during the last 6 weeks or so, from nutritional issues; it can be a drought response to a high level of dissolved solids in the soil solution, under-watering, or over-watering. It also appears there might be some mechanical damage (like a bruise would be to a human or animal) and some oedema symptoms on the calathea.

I can't see anything wrong with your plant, but there's a lot of mis-information regarding housplant care, so this info below will help keep your plant on the right track. FLFs love lots of light, eastern light is not very strong and this plant would do best right up in front of an unobstructed south facing window. If it can only reside in this room, it needs to be right in front of the window without the blinds blocking the light. You could even place in on a plant stand or table so that the leaves can catch as many rays as possible. I'm not sure the mirror has any benefit since the reflected light is diffused, but it's certainly not hurting anything. I would however stop misting because it does not improve humidity and sometimes invites pests. If you're interested in increasing humidity you should look into using a pebble tray, but the humidity in the South-East during winter isn't too bad, so it's up to you. The leaves may be drooping due to the soil being too dry currently or the soil retaining too much water. I don't think that plastic bag under the pot is a good idea as it can trap moisture inside the pot. Watering with three cups of water likely didn't water the plant thoroughly. Good watering practice is to insert a wooden dowel or bamboo chopstick all the way to the bottom of the soil - some people think checking the soil with your finger is effective, but it only evaluates the top inch, the bottom soil could still be soggy (over-watering is a common issue). If the dowel comes out wet with soil clinging to it, the soil is still wet and it is not time to water. Check every few days until the dowel comes out clean and dry. Then water thoroughly so that water flows freely out of the drainage holes in the bottom and then let it rest for about 20 min so the excess water can drain out, this is easiest in the shower or kitchen sink. Don't water again until your dowel is reading dry again.
