My husband to be is a new Muslim

Just to add, there is no need to rush him nor is there a need to then rush into a marriage. Sorry, I don't mean to be blunt or hurtful here but I feel it is necessary to say so... especially when your mother, who knows you and the groom-to-be, seems to be saying so. Who are we to say anything different here?

[edit: just one last comment - since he is looking forward to marriage, it is his duty to be ready for it in deen. Your mother can't stop you but I can tell you don't want to disappoint her and having read your replies to other comments I see that you acknowledge that she has a valid point. Just keep praying to Allah (SWT) and encouraging him; if he can't handle it or doesn't want it then maybe its best not to go into it and wait. I speak from experience, wait.]

It's not that he can't learn it or hasn't got the brain to learn. It's him making the time and effort to learn it . A start would be nice. She believes he doesn't want to learn and he believes no matter how much he learns she will never be pleased. It's a vicious circle. It's hindering him starting to some extent.

well you can't really blame your mother for thinking the way she does if he has really not made any time or effort to learn. A person who understands the importance of salah and a person who is devoted to Allah would make this their priority to learn the salah and pray them on time

if you have not done so already...do istikhara

As long as he is a Muslim, there is no reason to delay the marriage. Insh'Allah he will become much better soon after. Be patient.
