I have them in several pots, most from plastic, one is ceramic. All plants that are in plastic, I re-pot every 2-3 years, change soil as well. They are also getting nutrients every 3-4 month , all plants together. Amaryllis on ceramic pot was not re-potted for at least 4-5 years. There are inside 2 main blooming bulbs (3+ inches in diameter), and several small (baby) bulbs.
This summer after the bloom I found that leaves of the main bulbs are not dark green , as it should be, but more like light green, and sometimes even yellow and partially brown. Also the bulb is not hard as other bulbs, but much more softer, and several outside layer are brown/dead and can be pealed away.

Bulbs are dying ?? why ? Extra nutrients are not enough ? I need to replace soil in ceramic pot as well ?

Any ideas ?

several pictures

Hmmm - I wonder if they are getting too much hot sun? Are they in full sun, or partial shade. Mine get yellow when it gets too hot, or if they are in too much sun. You might move them to an area with partial sun, or to an area that is somewhat cooler - if possible. If not possible, maybe give them a bit more water.

Are the outside brown layers of the bulb dry, thin and papery, or are they soft and squishy, like rot? If dry, thin and papery, then that is normal. If soft and squishy, then that may indicate rot. If rot, then they might have too much water. If rot, I would peel off the outer rotted layers, let the bulb dry off in the open air for a few days, and replant.

my plants receive only morning sun, so sun is not a problem.Heat I cannot control, about 95-100 F in the middle of a day (in the shade). But all other bulbs in other pots have no problem with that, and all nearby, all getting enough water.
Bulb have several brown outside layers, but if I squeeze the inner bulb, it is too soft, not hard like bulbs in other pots.

Then I suspect the bulb is rotting. You can try removing all the soft layers of the bulb and see if there is still part of the bulb in the center that is firm and still ok. If so, I would set the remaining bulb in the air to dry for a few days before replanting it.

So, re-potting a a good idea anyway ? It a ceramic pot, it will be very difficult to remove bulb from there, But I will try.

I checked the bulbs now again, it is not very soft, it is a little soft, like you have a bulb after a big bloom in the start of the season without any leaves.

I more thinking about old soil that was not replaced for 4-5 years. Can this be the case ?

Well, you said you have been fertilizing the soil? Then it may be OK. Although if could have an imbalance of nutrients I suppose. If the bulb does not seem as soft as before, you may just want to dump out some of the soil and replace with new soil.

Dumping some of the soil is impossible, there is actually no more soil in the pot, only roots. Local amaryllis strain love to produce huge amount of roots, usually within 2 years (mostly less) all soil in the pot got replaced by roots, no mater the size the pot you use. Only upper, less that in inch think layer is actually soil.

can you dump off that upper inch of soil then, and replace it with new?

I did it, but it will not help much. I will have to somehow to remove bulbs from the pot, maybe by braking it.

I have run into that same problem before, but as long as the actual bulb is smaller than the lip of the pot, you should be able to get it out. Lay the pot on its side, and start coaxing out any soil that you can, all around the edges. Then grab the leaves, as a group, low down by the soil line and start jiggling the bulb back and forth, while tugging gently. sooner or later, the bulb should come out. Good luck! Crossing Fingers!

I removed one of the small bulbs from there, about 12-13 cm in circumance. As you can see, it look strange, all its 2 leaves are light green color with brown dots and bulb, although it is green and hard, has only one root.

yes, I can see that the leaves are not very dark. Some of mine look the same way, but we had very high temperatures so I think it is heat stress.

The yellowing leaves don't look particularly diseased, but perhaps they have a nutrient deficiency due to being so crowded. At this point you may need to break the pot and pot up each one of the original bulbs in fresh soil. If you do repot, you probably will have to reduce the length of the remaining leaves, so they don't wilt too much. The baby bulb with the one root doesn't worry me too much. Sometimes they do take a long time to put out roots. Since it is only in this one clay pot, it is certainly worth trying to save the bulbs. If this is something that is spreading, then you might have a disease issue. You can use a systemic rose/flower anti- fungal treatment if you are worried about disease, but I don't think you are at the point quite yet. As Christie said, it could definitely have something to do with heat stress.

thank you for all, I will try to split and re-pot them, although I'm out of space. I will have to send most of them to my friends.

@sangel - an old, long-time, noted gardener in our community once told me that when you share your plants, you are sharing the blessings of God (or nature) and are therefore also blessed yourself. I tip my hat to you. Group hug

Amaryllis that I have growing outside in Florida had their leaves turn yellow this summer. They looked like those in the last picture you posted. Several trees around my property had been cut down, as a result the amaryllis now receive full sun. With the onset of Fall, sunlight has been reduced & the leaves are now deep green. I'll probably relocate the plants to an area that receives less sunlight.

I have an update. first sun is not a problem, it is almost 100% shade anyway, almost no plant will grow here in a sun (maybe cactus will )

Second I found a problem : the soil in this pot was too much clay. Removing plants from this soil, splitting them, cleaning bulbs end then re-potting to a new soil made from coconuts helped. One of the thing I found when removing bulbs from clay soil was almost lack of roots, and bulbs were very soft on touch. Now after several month in a new soil, new roots grew up and several strong green leaves came out.

Ron: that is very interesting, that repotting into better soil, made such a positive difference so quickly.

@bsharf

here is a pictures now. new pot with a new soil (except for two 1.5 " in diameter bulbs that I planted elsere). Roots are very strong, leaves are dark green (except for one near the red pot).

About 3 month after re-pot.
