I just made my first Geranium buying trip last week and I managed to get 8 large pots filled with a variety of pink, red, white and peach flowers. Notice I said first trip because...I have two more trips to make to the nursery. I try to spread them out so the damage to my credit card gets spread out as well. I'll be making another trip for more Geraniums and some other flowers, again next week.
I go to a gardening center that is about 40 mins away from where I live. Reason being, that I love there selection of Geraniums. It doesn't hurt that this town has the best chai lattes known to man so, no matter how hot it is outside, I stop in and get a chai on my way home. Large, extra hot, with spices on top.
I Miracle Grow my potted plants once a week, from the time I plant them, until the end of the season. I've read lots of different theories on this , whether you should or you shouldn't but I firmly believe in Miracle Grow. I use it for my perennial garden to, just not once a week. But for annuals, I don't know, summer is so short and hey, I like my flowers big. I've found it gives me the biggest and longest blooming flowers so, it is well worth the little extra effort.
