I just got some liquid fertiliser for my citrus plants. I wondered if it would be suitable for figs. The ratio is 2.3: 1.2: 3.8

This is the stuff: https://www.amazon.co.uk/Citrus-Balanced-Concentrated-Liquid-Fertiliser/dp/B003WAYCZ4/ref=sr_1_1?ie=UTF8&qid=1493903399&sr=8-1&keywords=citrus+fertiliser

No reason whey it wouldn't work. I use Osmocote.

I often end up using comfrey liquid for most things but for citrus I find that some can be fussy about fertiliser. I haven't been growing figs long enough to see their reaction to different feeds.

I had a lot of citrus and they were fussy so I got rid of them. They grew to quite a size - six feet was my tallest. I'm using Osmacote since it's slow release and figs don't feed as much as other plants apparently.

I hear its good in pots, might try some, will let you know if any plants get burnt.

Edited to add: OK I do not have that brand on hand, I bought EPSOMA citrus and avo, at Walmart (did the Walton family invade your Isle?).

It is 5% Nitrogen, and slow release, to very slow release. It is actually meant to go with the soil in the pot.

I need to up pot some figs, if all goes well, I may make a thread of it.

For citrus I use a high nitrogen fertiliser. Citrus needs more nitrogen than any other macro nutrients . Plus they need magnesium and iron. Scientifically the nutrient intake ratio for citrus is for every 5 nitrogen they need 1 phosphorus and 1 potassium. This is if you want to harvest edible fruits . Somewhat similar to that ratio will work also. But for an ornamental tree any fertilise would do. For figs in our climate since breba crop being the dominant crop a high nitrogen fert might make them drop and this has been happening to me. I use NPK 141 ratio followed by npk 123 or 113 in summer. For main crop only varities I use NPK 312 follows by NPK 113 or 123. I also add micro nutrients every other month plus some organic stuff. This works for me and you can easily find fertilisers with the above ratio. As kelo said osmocote is good also but the only good one for citrus is the Osmocote pro top dress.

I use 13-13-13 for my in ground satsumas,it works well.Not good for figs though.
Try Becnels website for citrus .

Vigoro Citrus and Avocado works great in our soils because it have micro-nutrients which we often lack.  Bottom line is figs will eat almost anything.

Thank you everyone for your responses, very useful info. Vinny, that is just the sort of info I had hoped for. I had wondered if the high nitrogen in the citrus feeds might be bad for fruiting figs. What brand do you use?

Miracle-Gro Water Soluble All Purpose Plant Food has a ratio of 24-8-16, which means that it contains 24 percent nitrogen, 8 percent phosphorus and 16 percent potassium, as expressed in the national standard format but too much for figs.

Osmocote Pro

Thank you kelo and vinny, much appreciated!
