? re: initial fertilization w/ 5:1:1 mix

noleradMarch 3, 2014

I am going with Al's 5:1:1 mix for my container vegetable (predominantly tomatoes) and herb garden this spring. I will be using Dynamite Select All-Purpose Indoor/Outdoor Fertilizer (15-5-9) as the initial SRF when transplanting to the containers. This will be supplemented during the season w/ Foliage-Pro and Pro-Tekt.

The Dynamite web site states the following: "For new plants and transplants, sprinkle Dynamite into the hole near the roots and then backfill." In a full 20 gal container and applying at the recommended rate of 1 Tbs/gallon of soil, this would result in a total fertilizer volume of 20 Tbs (1.25 cups).

This seems like an awful lot of fert to place so close to a fragile transplant. Would it be better to mix the Dynamite throughout the soil before digging the transplant hole? If so, would this mixing best be done after moistening the soil?

Thanks for your help.

So the tomatoes are in pots and the herbs are in the ground? I can't tell if you're talking about the ground or pots in your post. Can you clarify?

Everything will be in pots. Sizes will vary, with the largest approx. 20 gallons. Thanks.

Definitely mix the Dynamite throughout the soil before putting it in your pot. It would hurt roots if it was all clumped together like that.

1.25 cups in a 20 gal isn't excessive. Yes, mix it in well. No need to moisten first, but water well after you're all planted.

If you ever forget like I do sometimes to mix in the initial CRF application, then just sprinkle a little bit on top of the 5-1-1 surface in the pot and mix it into the first inch or two. Then remember to apply more in a couple of months as the weather heats up. Light and more frequent always preferred in pots over heavy and infrequent fertilizing.

Also, with 5-1-1, there isn't really a transplant hole and backfilling. That's why you confused me. You make a volcano in the pot, splay out the bare plant roots and lay radially on top of the volcano. Then you fill in carefully doing your best to get mix in amongst the roots. You'll understand once you get your first planting under your belt.
