You may need to repot it in a faster draining soil. Avocados are usually grown in coastal areas with a lot of sandy soil. Lighten the soil a bit and this will give you a chance to look at the roots. If ant are rooted cut them off until you get to healthy roots and sprinkle with cinnamon, let it sit for a day or so. Then water sparingly until the roots heal.

It could just be typical transplant shock...it may come out of it eventually. Did the soil you used have any fertilizer in it? My sister used that type once accidentally when transplanting an indoor tropical and killed it.

Your fern's leaves look a lot like feathers. My guess is that birds are snipping them off to use for nesting material. They often do this. If it were bugs, they would not snap them off where the leaf meets the stem (mostly), they would do haphazard munching leaving scallops and holes in the leaves. It does not look like bugs to me. Your ferns look healthy and they can surely survive losing a few little frondlets. I wouldn't worry unless it got much worse. In the meantime if you think there may be bugs, spray the ferns with some homemade cayenne pepper spray. Lainey

You can get rid of a boat load of aphids and spider mites by the careful spraying of plain water to blast them away. Not so strong that you could cause plant damage, but enough to get rid of the critters. Spider mites tend to congregate on the underside of foliage, so pay some attention to that location. Use your fingers, too, to help squish. Then, you might try an application of insecticidal soap, mixed according to label directions. Again, direct the spray to all parts of the plant. I've found that spider mites can be controlled by applications of alcohol and water (in a 1:4 ratio). Save that remedy for when you bring your plant inside or out of the direct sunlight. Same goes for the soap, too. I should say that spider mites can be very difficult to get rid of entirely. Aphids, not so much. But you will have to do a much better job at observing your plant from now on, so that you can continue treatments. Pest populations like that don't occur overnight.
