#2.Lilly Miller Morcrop Vegetable Food 5-10-10

While we know that the Lilly Miller Corcrop is intended for vegetables, we actually find that it works miraculously for dahlias as well. You just have to kind of take a leap of faith and try it out. While this may not be the best dahlia fertilizer in terms of overall efficacy compared to Jacks Classic No. 4, it sure does work great on certain batches that just can’t seem to grow properly.

We like that it is specially formulated with slow and quick release nitrogen which works wonders with dahlias actually. Also, it is fortified with essential plant minerals, also great for dahlias. Overall, this product is great but a bit less consistent than the Jacks Classic No.4. This just means that you will get some dead plants every now and then.

#5.Osmocote Smart Release Plant Food

Lastly, we recommend the Osmocote Smart Release Plant Food, which has a high total nutritional content. This is a 14-14-14 fertilizer and works at pretty low soil temperatures. We think that it does a really good job in promoting strong root growth as well as a lush above ground growth. The Osmocote Smart Release contains a nutrient granule coated with semi-permeable resin.

The standout feature is the fact that it has a smart release, which basically means that the coating will allow water to penetrate it and release the nutrients inside. Also, we like the idea that more nutrients are released during warmer temperatures where it is more beneficial for your dahlias.
