Hi again!
I usually buy plants from the grocery store and the store typically over waters plants and sometimes fail to provide drainage(with all the fancy packaging). Either way, I have had three plants get moldy from being over watered. The first two I just replaced the soil and disinfected their pots. What should I do when I get an over watered plant from now on? Thank you!

I would buy my plants from a better source if possible. Do you have a decent nursery nearby?

I agree with Ursula, find a better source for your plants, if they have been over watered you dont know how long the roots have been sitting in the wet soil and root rot has probably already started.

Agree, I wouldn't buy a plant that looked like it was struggling. Even if it was on clearance, if it dies, that's just like throwing $ away. I'd much rather pay the regular price for one in normal condition.

I suggest that you buy your plants from a nursery and your food from a supermarket!
The grocery does not get involved in the plants they sell nor the oranges they sell.

I don't know. I have a nursery near by but they have a ridiculously small selection. Also many of the over watered plants I buy are in great shape and they are not in clearance. Like my lavender plant, it is growing now but a few days after I got it it got all moldy. I replaced the soil and its fine now. I just wanted to know what to do if I had really soggy plants.

The source of the plant is not usually the problem. I can't tell you how many plants I have rescued from apparent death in co-worker's trash cans, LOL! They claim I have a "green thumb". Maybe, but what I do is give them a chance to survive.

A fresh pot of decent soil, a light tough watering them with aquarium water, average sunlight, and most recover. Sometimes it takes a while and you have to be patient. Plants are patient too.

And don't be afraid to tap them out of the pot. Sometimes the soil stinks (figuratively AND literally). I have sometimes just carefully washed off all the old soil and set them down in cheap pots in new potting soil and tapped around the roots until there were no air pockets around the roots.

And I suddenly have a whole new plant, thriving!
