Welcome Jenny!
League City on Galveston bay in Texas? I bet that has very different summers from England!
>> I have just potted on some new cuttings
Does that mean they were already well-rooted in water, or were they rooted in one pot and now you've moved them to bigger pots?
I've read that "water roots" are poorly adapted to soil or soilless mix, and take a while to get used to it.
