So I was at my local nursery today looking for sweet 100 tomato plants when I came across a huge hanging petunia - gotta be three feet across. $29.95 later it's hanging by my front door and I'll get the tomato plants tomorrow.
It's absolutely gorgeous with lots of dark violet flowers and I'd like to keep it that way. The hanging pot that it's in is plastic. Any hints on care for something like this? Water it once a day? Fertilizer? I'm located about forty miles north of New York City in Zone 5.
