I have 10 dahlias that have not bloomed yet. Can I give them some 10-50-10 Shultz or is that a bad thing to do?
You did not say, so I have no idea if or when you have fertilized this growing season, so I would rather not comment. I have a set of instructions written by Swan Island Dahlias which I am willing to send to you if you send me your e-mail address. Please mention what you want me to send to you. I get a lot of spam, so I have set my filters very high, therefore I ask you to PLEASE put the word "GardenWebber" in the subject area to keep your e-mail to me out of my junk pile. THANK YOU.
The nitrogen amount of 10 is a little high for this time of year in your area. We always cut the nitrogen to 5 or less after the first of September here in the South so our blooms won't be spindly and the tubers rot during the winter. Also, too much nitrogen during the late season can keep the eyes from forming.
You might use it during this last week in August but after this week I would go to Mor-Bloom 0-10-10 (google it) and you can double the strength per gallon and make it 0-20-20 without any problems.
There are a couple of other blooming agents that work well and both have seaweed. Maxsea 3-20-20 (google to find it) and a new one Sea Grow 4-26-26 from Charley's Greenhouse.
These should get those plants blooming
Thanks so much. I think the nights have just gotten so much colder. I didn't do the Shultz. Will look into the 0-20-20 Thanks
