Which one does everyone prefer?

I have never heard of a foliar slow release. - Millet (992-)

Do you prefer foliar fertilizer or a granule slow release fertilizer?

I prefer granular slow release fertilizer because there is less risk in damaging the roots and nitrogen is released more slowly and longer lasting.

I use both Osmocote slow release fertilizer, and regular water soluble fertilizers. Using both in a nutritional program, eliminates the feast and famine approach to fertilizing, that can happen when only water soluble fertilizers are used. - Millet (991-)

I also use both along with Epsom salt.

I was using only water soluble but it's just getting so darned time consuming for my 100 container trees (not all citrus). I recently applied Dynamite 18-6-12 (and some 18-6-8 when ran out) to nearly all my citrus trees. Hoping to only do WS ferts like once a month during growth season.

On the same topic, Millet -- what ratio and frequency are you using the Peters 25-5-15 in conjunction with which Osmocote?

On almost the same not , I apply some Spinozad to control leaf mineres. Would it be good to mix in some foliar fertilizer with the pestecide? And if so which foliar would be good?

c4f,

Which Dynamite is 18-6-12?

From what I have dug around, the Dynamite is repackaged Nutricote CRF formulas.

These seem promising, as the formulas also include minors.

C4F, sorry for taking so long to answer your question. I was in Washington DC over the weekend, from May 6 until the 9th. I'm always glad to get out of that city, even though I stay far away from all the tourist sites, DC is always a crowded mess. To answer your question, along with the slow release fertilizer, I apply 25-5-15 at the rate of 250 PPM N. Form a month before expected bloom to a month after fruit set, I fertilize every time I water the container. Then for the rest of the summer I fertilize every other time I water. During the winter, I fertilize every other time I water, because the tree is growing inside a warm greenhouse with high levels of light. - Millet (980-)
