Hey all,
I've recently transplanted my meyer lemon to a CHC + peat moss mix(woo hoo. no leaf drop). And, fortunately tiny little leaves are beginning to emerge where the mass flux of other leaves fell off.

Now, I'm wondering when I should begin fertilizing my tree?
I've looked on the internet and can't seem to find any ideal citrus fertilizer(read 5-1-3).

In my house, I have this plant fertilizer thats 10-15-10. With trace minerals of iron, manganese and zinc. Would that do more harm than good?

I'm not above diluting my pee and pouring it on my plant(at the 1:10 ratio I've read)..

Thoughts?

Thanks all.

ALSO my meyers new susbtrate was soaked in epsom salts.
Not quite sure the purpose of that was, but I did it.

A citrus tree uses nitrogen, phosphorous, and potassium plus the trace minerals. For every 5 parts N, a citrus tree only uses 1 part P, and 3 parts K. Your formula 10-15-10 has P as the highest element, when the least element a citrus tree uses is P. - Millet (662

The Peters is good. I think Dyna-Grow Foliage Pro http://www.dyna-gro.com/936.htm is a great one for container citrus. It has all the micronutrients needed for Citrus, including Magnesium and Calcium -- which are rare to find in any soluble fert. It isn't in 5-1-3 but it's 3-1-2 which is close enough IMO for a container citrus. But it has more micronutrients than Peters, which again IMO is more important for containers than in-ground.

I add a small amount (like 1/2 tsp / Gallon) of white Vinegar to the water then mix in the Foliage Pro. That will make the solution a little more acidic so Citrus can take it up better. Exactly how much vinegar you should add is different depending on your water supply. Get a simple pH test from the pet store or borrow from someone with an aquarium, you only need a few. Then you just add a tiny bit of vinegar at a time to a gallon of your water until it reaches between 6 and 6.5 pH.

Using the fert you already own once or twice won't hurt your tree since you are using a good draining mix, it should just flush out all the extra unused P. But I wouldn't even consider doing it for the long term, so buy the right one from the start.

Thanks for the input Millet and C4F.
Buying a 50lbs(100$+) bag of fertilizer is a little out of the question right now for one little citrus plant(/as a student who barely has enough money to pay next months rent ahaha). And, unfortunately I can't find any DynaGrow sources in Canada.

The search continues, I'll limit myself to one use of the crap fertilizer for now.

I am sure wherever u r, the stores carry miracle grow. It's 3:1:2 and contains all trace of minerals. http://www.amazon.com/Miracle-Gro-1001232-Purpose-Plant-Food/dp/B000P6QYJK/ref=sr_1_2?ie=UTF8&qid=1301427997&sr=8-2

Thanks again for the tips guys!!

Hey Sparkes

I'm another Canadian citrus grower as well. It's very hard to find fertilizer in Canada all I use is Miracle-gro 24-8-16 but now they started taking out the calcium out of their products so I have nothing else to turn to. There is no dyna-gro,dynamite, and jacks in Canada and bringing and other fertilizer products in from the Usa from either Ebay or amazon is illegal and prohibited. So i'm in the same boat as you. I was thinking of using Oscomote but there are no micro-nutrients.

You can add some granulated gypsum (CaSO4) to your potting mix for calcium (or even Dolomitic garden Lime) - I use 1 tablespoon per 2 gallons of potting soil as a conservative estimate. And use epsom salts for Mg. That way you can use the all purpose Miracle Gro product that you find in Canada and still have no deficiencies.

Good to know I'm not alone .
Thanks for the advice Sludge/Ashley!!
Will do next time!!
