If you are getting good sounding low notes within 9 months of playing, you are doing very well. You might try this exercise to increase the control while tonguing the low tones.
At a slow tempo play low C as a whole note (semi breve) then tongue four legato quarter notes (crotchets) and then play another whole note (semi breve) all on the same breath. Concentrate on keeping the throat open, the airstream moving and well supported (pressurized) and the back of the tongue down (as saying "AHH") when you tongue.
When legato tonguing starts to come out well controlled, then do the exercise with regular tonguing, and then staccato.
