Cecil I was thinking about your figs affected by heat.
In order to avoid excesive heat problems for in pot figs,a remedy that works for sure is Pot in pot.
Placed the original pot with the fig,in it,in another larger pot.
In between the walls fill it with Light,Packing,material,insulation,or shreded Newspaper .
Of course make sure The drainage is still functional,and if needed drill more Holes.
This is needed because when the soil gets hot ,in the pot it create all kind of problem.
The Texas heat will be defeted,for sure,with this method.
