I flowering amaryllis

[mr bartley green]

I've had an amaryllis for years. There is 3 or 4 bulbs in same big pot. The leaves are a good two ft tall but it hasn't flowered for at least 3 years. It's in a sunny spot near a window..and it seems to like where it is as the leaves are tall and green but it hasn't flowered for years. I water it and something add some baby bio so what am I doing wrong

Never grown them sorry but this website I've given a link to below seems to have some good info:
https://www.evergreenseeds.com/why-isnt-my-amaryllis-blooming/

I had a quick look and according to that it seems like too much nitrogen can give you lush green leaves but hinder flowering like a lot of plants so maybe wait a while and then try a bloom nutrient instead of baby bio.

I use the biobizz products called: 'bio-bloom' and sometimes also some 'top-max'
I usually get it from amazon website or ebay. It's not cheap but it's strong stuff though, you only need a drop in some water. Use less than what it recommends on the bottle to start with or you can possibly burn the leaf tips. I make a very pale, weak solution if I'm not sure; just a faint tint of colour in the water.

The article also mentions too much water or lack of soil aeration.
It also mentions the plant needing a dormancy period.

Just some thoughts though based what I read there but you may get some other more experienced replies.

You more than likely need to repot them. After three years the soil has nothing left to offer I would repot them individually, not all in one pot. They need an inch of soil around the edge of each bulb.

When you find your leaves are growing two foot long, that's a sign that they are reaching for light. Give them more light, new soil and they should bloom for you.

Yeah good advice, more roots more fruits at the end of the day!

They need to be cold for a period to flower, had mine in the greenhouse last winter and it was mild, only a couple flowered, I'm leaving them out this year. I can't remember the temp. off the top of my head, but I know a lot of people put them in the veg tray in the bottom of the fridge for a couple of weeks. Apparently you must not have apple in the fridge at the same time, it makes them sterile.

Good post @Oliver Buckle and to add to it, the temps they need to promote re-blooming are 50-55 deg F for several weeks. Storing them in a cool, dark place after the foliage dies back in late summer or early fall generally gets the job done.

The real key to getting them to bloom is LIGHT! Lots and lots and lots of light. Like full sun all summer long lots of light. Any time the temps are above 25*F full sun lots of light. I grow them in the ground in full sun with winter lows to about 29*. Light, light and more light. A little extra phosphorus is helpful, but not critical. More light.

But my amaryllis don't die back. Occasionally a leaf will go a bit yellow and then die back

 

[mr bartley green]

My amaryllis are by a sunny window that has partly open window blinds so they get lots of light..I'm going to do what you said and put them in slightly smaller pots and replace the soil

Doesn't matter if they die back or not. They need as much intense sun/light as they can get.
To induce dormancy you can let it get a chill down to 40* or less. If it takes putting it outside for a week or two, it can handle the chill.
If you do repot it, try to not disturb the roots too much. Monocots like Amaryllis don't get 'rootbound' in a way that harms their health and vigor. The roots get longer, but don't get fatter, so they don't girdle each other or the stem. If you do have to cut some, it won't kill them, just set them back a little.
The real key, like I said, is light, light, and more light. If they don't get enough, no amount of fertilizer or fresh potting soil will stimulate blooms.
