Review: Good product - I've been winning plants at 'Plant Bingo' at our local shop and really want to keep them alive. lol This plant food perked up a couple that were looking questionable and are now blooming, so I am totally happy with it. A little goes a long ways for house plants so I will add some to my garden plants this week, too.
Review: Beyond impressed at what this does for my petunias - First time using this brand and I just have to say WOW. My container petunias that I just planted a few weeks ago are absolutely thriving, tons of lush growth and flowers with an insane number of flower buds popping up on the stems practically daily. I'm really impressed so far and can't wait to see how they finish out the year. I would have bought fewer plant starts if I knew I'd be getting such excellent growth! I'm going to have to thin out my containers and I'm not even a month into the season. It dissolves immediately in my pump-action sprayer and mixes well in the can-type waterers as well. I'm using this along with a yucca solution to maximize nutrition and proper moisture for petunias in coconut fiber hanging baskets, my Wave petunias puffed up 2x as thick with leaves in just a week! I'll take some before pics and share with after pics once the season is over. If you're thinking about this fertilizer...DO IT!!
