How Deep?

Posted by honnat (My Page) on

I just got done planting some dahlia tubers (2 black wizards and 2 Isadora). I bought them from a garden center. Brand is "Netherland Bulb Company". The package says that I should plant them so that the top of the tuber is 1 inch below soil line. But now I am reading that it should be 4-6 inches down. Should I get them in deeper?

RE: How Deep?

In my sandy soil, I plant 6 to 8 inches down. The stake is put in the hole before the tuber to avoid damaging the tuber later.

RE: How Deep?

I agree with "grannymarsh", but my suggestion is to plant that deep, but cover the tuber only 1 or 2 inches, then, as you new growth appears, fill the hole until you are even with the surrounding garden. It would be better to lighten up the soil with compost, and, or, perlite, or, fill the hole with something like Promix, or Sunshine mix.

Good luck!
