what is the name of this plant?

this is in my mothers yard,she wants to take care of them better,but doesnt know what they are. I told her someone here will know. :) thank you for your help.

 

Clivia

 

thank you Ron! ;)

 

They are forest dwellers in South Africa, with fairly dry, cool (but above freezing) winters and moist summers. Yours look like they're getting too much sun.

 

thank you very much, i better move them :)

 

I'd inspect them for mites. Look for fine, dense webbing with tiny speckles on it. Use a hand lens if you have to.

 

if free from mites ...what can we do if they are already planted in dirt; can we improve it somehow and help them bloom? Do we have to move them all?
any suggestions?
