Alstromeria plants

Alstromeria -  Planted bare roots in tubs beginning of January.  All have grown stalks that are almost 3' high. They look healthy but no sign of flowers. They are growing taller and taller.  What should I do?  Do I remove the existing stems to promote new growth or leave them as they are in the hope?  Any advice will be welcomed.

I wonder what sort they are? Alstromeria come in many sizes. Some flower at about four inches but the commercially grown ones that are used for cut flowers can be six foot or more.

Plenty of time for them to flower, I have a large clump and no sign of flowers yet.

It is very early, they will flower in Summer.

Some of mine didn't die down at all over the winter and by the beginning of April they were very tall. I cut them right back and they are growing away again with plenty of flower buds. They are quite forgiving.

Interesting that you cut them back, I’ve read that you are supposed to pull them, right from the base to promote new growth,  what do others do please?

I pull them like pulling rhubarb as per Sarah Raven.

I only cut the the whole plant back because it was too large too early in the year. When it flowers I also pull the spent flower stalks.

Thank you for your comments.  When would you cut the whole plant back, i.e. which month would you consider the plant to be too large too early.  Never grown them before.
Would you consider them to be too large at 3' at this time of the year?  Would appreciate your comments.
