Two jobs and a garden

I was fortunate to be hired at a new job that provides insurance benefits at a reasonable rate with a more realistic hourly wage which makes my other job look like i'm a chump. The new job is at a blue home improvement center with a decent reputation and i really do enjoy it. But i'm so new right now and i feel so green. Its not beyond my abilities but the learning curve of the cashiering system that honestly is almost archaic, is very steep.  The thing is that i love my old job too so, though i did give my official notice of 2 weeks, i was asked to stay on if possible. My "old" job is at a nationally known craft shop that does not have a reputation for high (some say unfairly low) wages and part time comes with no insurance benefits. 

The company itself may not be the best but the people i work with at my location are pretty darned cool. Smart, kind, intelligent, committed,  creative....   I have to keep my job with benefits but i don't want to leave my old job. in the last 32 days i have had 4 days off.  But 2 employers is nothing new..  I'm pushing 40 and i'm not a feminist in today's sense of the word but i'm expected to also be a mom and wife, so when i get home from one job or the other,  i don't get to just hang up my car keys and supper miraculously appears, the kids things are ready for school tomorrow and the pets get fed...laundry delivers itself to respective machines, lunches make themselves and ....well, whatever.

what to do about the garden?  if i keep this up i won't have time.  i'm thinking of just black plastic mulch for the entire garden and using drip hose.

Let's see.
