I used to use miracle gro, til I discovered horse and chicken manure, vermicompost and urine. Whoosh! This stuff is good! I've got tomatoes growing like grapes. Your father would've been doing you a big favour releasing his coffee! I've got a test plant that I fed urine to for 2 days (test plant cuz I didn't believe all the reports that it's a good idea) and it's green and lush. The others are struggling a bit since running out of vermicompost.

nasturtiums don't like wet. I've bought plants in the past, had them in pots and watered them religiously. They suffered and sometimes died. This year, we're having long stints of high temps with little water, I seeded some directly into the garden and they are glorious.
