For the last two gardening seasons I have fallen in love with Bayer Garden products.
I'm an avid gardener with an abundance of roses that are
supposed to be pest and disease free. They are far from it (see picture above). The first year I planted my roses they were so eaten up by insects they were just twigs sticking out of the ground. A landscaper suggested I pull them out and throw them away. Yea, not a good idea for what I paid for those roses. Plus, I really wanted them to be beautiful and thrive. I researched and found I had sawflies, Japanese Beetles, Aphids, etc..
I tried
Bayer Advanced All-In-One Rose & Flower Care.
This stuff works!!! I used to spray EVERY day and now I just put this at the base of the plants and shazam... Deed done. Give me a nice cold tea and a hammock I can rest in for the next few months. This stuff keeps working that long. I put this on my Oak Leaf Hydrangeas when I saw they were getting black spot. It stopped it dead in it's tracks and the leaves looked flawless the rest of the season. I love this stuff. It is so effective AND easy.
From personal experience I would suggest following the storage temperature suggestions. I left mine in the shed in this northern climate and it wasn't quite as effective this year. I bought a fresh bottle and it worked as good as ever. I find if I put it on during the time of new growth it is even more effective.

Since the product for the roses and shrubs worked amazingly well I checked out other Bayer products for the garden. For my trees I chose the systemic treatment they call
Bayer Tree and Shrub Protect and Feed. This one is even easier to apply than the one for the flowers. Japanese Beetles used to plan their meet and greets in my trees every year. Not any more! In fact, I don't have issues with any pests at all now. How about another gallon of iced tea and a cabin on the lake because this stuff lasts for a full 12 months! At first I thought it was a bit pricey but when I thought about it I only apply it once a year and it works great.Again, with this product, it seems to have worked best during the time of new growth.
Now for the feeding part. My house was built last in the row of five homes. Thus, my Crimson King Maples were the smallest. I put this product on them this year and they are NOT the smallest anymore!! I'm amazed every time I drive by the row of trees. I could almost see them growing. They are now the same size as the neighbor's trees which were planted three years earlier than mine. I plan to put it on again next spring. The goal is to get them even bigger than the neighbor's trees!
