5-1-1, fertilize or not?

Phildeez(9b)April 12, 2011

I have this random fertilizer called Multicote. It is an "up to 8 month" fertilizer with a 9/3/6 ratio. Should i mix this in before potting? I also have MG Tomato 18/18/21 that I can use throughout if I do not fertilize now.

My mix is 5 parts fine redwood compost, 1 part potting soil (2/3 potting, 1/3 local), and 1.5 parts coarse Turface, because i messed up and spilled it when pooring.

The potting soil is Kellogg's Patio Plus. The redwood mulch is pretty darn fine compared to some pictures I've been seeing, with a lot of dust and small particles. I added a small amount more potting soil and redwood to make up for the 1.5 of Turface. I don't figure slightly too much turface will be a problem when I am aiming for hot weather tolerance.

On top of fertilizer, do I really need to worry about lime if my water is hard and has loads of calcium and other minerals?

Hey, Phil!

The quick answer is, No, you don't need to include the slow-release fertilizer.

That said, let me give a longer answer. If you suspect that you might not fertilize
as regularly as you hope, then you might consider mixing in some of the slow-release.
I use Osmocote 4-month because I'm not as consistent with fertilizing as I should be.
With a 4-month formula, I can also be fairly certain that the fertilizer will be gone
by the end of the season.

In fast-draining soils, these slow-release products don't last as long as advertised
for the simple fact that we water more often - which has the benefit of flushing the soil.

Gotcha. I held off, I will fertilize too frequently if anything, withOUT the slow release in there. I was more worried about a variation in the two ratios and that the slow release might have been a more desirable proportion of each. I know I saw that Al uses a fertilizer with the same ratio, but that Foliage Pro has far more micro-nutrients. Also, the potting soil I used contains bat guano and a couple other compost ingredients.

4/6 plants are repotted and looking happy on day one. Just the pair of Habs to go!
