There is a mild issue - and it is probably this specific trailer more sensitive to something in culture... dry air may be. What I was going to mention is there is a trick for trailers - and it is - shallow pot. Seems that it is potted in the same way as the standards - something like 4 inches pot - and it would benefit if you put it in something shallow - half of the height of the current container. You can just take the scissors and make a shallow pot out of the similar one or make holes in a small plastic tub for whipped Philadelphia cheese. It will eventually graduate into 5 inch bulb pot.

While repotting - remove a good amount of these yellow leaves and half of the green ones - and you probably will need to trim a root. You need to leave some of the stem exposed, do not bury it - wen the bare stem of the trailer is exposed - it will send suckers - new crowns - and trailers are looking the best and blooming the best if you have at least 3 crowns on the plant.

Be brave

Thanks Irina! Just learned something from you! Rosie

Rosie - you know it, I am sure... but you prefer rosette type plants.

Irina, you are great. You can tell what pot I use. Yes, I use 4 inch tub pot from violet showcase. Is it considered shallow? Actually, this plant has 3 other crowns grow from the base on the other side.

Thanks

IT needs a big cleanup. All leaves that are pushing on one another creating a cockscomb on a top should be removed. Start with outside removing old yellowing leaves. Then get inside and remove all the leaves that are pushing on the other rosette - or almost pushing. Look again, take the leaves that are too big anyway. Yo will have a pretty sparse plant. Repot it in a 5" bulb post. In a month it will all leaf up and look good. In a couple more it will be blooming.

But Irina,,,,I love trailers also. I have some!!! Rosie
