Growth Technology Citrus Focus 1 Litre - Specialist Feed for Potted Citrus Trees
Best for: Anyone growing oranges, lemons, limes or mandarins in pots or containers who wants a feed actually formulated for citrus rather than a generic all-purpose plant food.
Our thoughts
Worth flagging clearly: this is a citrus tree feed, not a hydroponic nutrient for cannabis or veg crops - if that's what you searched for, you want a different aisle entirely. But if you've got a lemon or orange tree in a pot that's looking a bit sorry for itself, this is a proper, purpose-built feed rather than a bottle of generic "plant food" with citrus on the label.
Growth Technology Citrus Focus is a balanced liquid concentrated fertiliser formulated specifically for citrus trees grown in pots and containers - oranges, lemons, limes, mandarins and similar. It's part of Growth Technology's "Focus" range of plant-specific feeds, the same family that includes well-known products like Chilli Focus and Tomato Focus, built from mineral salts enriched with humic and fulvic acid to improve soil fertility over the long stretches between repotting, plus added seaweed as a nitrogen source.
Because container-grown citrus can't send roots out to find more nutrients the way a tree in open ground can, regular feeding matters more than it does for most garden plants. Citrus Focus is designed to be used weekly through the citrus tree's active growing period, roughly March to October, supporting healthy foliage, root development and fruit production without the guesswork of trying to adapt a general-purpose feed to a fairly specific plant.
How it compares
It's a specialist feed rather than a generic one, which is really the whole point of buying it.
- Against a generic balanced liquid feed like Miracle-Gro All Purpose, Citrus Focus is formulated around what citrus specifically needs, rather than a one-size-fits-all NPK ratio.
- It sits in the same "Focus" range as Growth Technology's other plant-specific feeds (Chilli Focus, Tomato Focus and others), so if you already trust one of those for a different plant, the same formulation logic applies here.
- It's a soil/container feed for fruit trees, not a hydroponic nutrient line - it's not designed to be dosed by EC/PPM targets the way a cannabis or veg hydro feed would be, so don't compare it directly against those on strength or dosing method.
If you specifically need to feed potted citrus, this beats reaching for a generic feed and hoping for the best.
Usage guidance
Simple dosing, applied through the growing season.
Dosage
Add 10ml of Citrus Focus per litre of clean water, applied weekly.
When to feed
Feed regularly from March through to October, covering the citrus tree's main growing and flowering/fruiting period. Reduce or stop feeding over winter when growth slows down.
Where to use it
Suited to citrus grown in pots or containers, indoors, in a greenhouse or conservatory, or moved outside for the summer months.
Technical specifications
- Product type: liquid concentrated fertiliser for citrus trees

Who this is for
- Owners of potted citrus trees - lemon, orange, lime or mandarin - grown indoors or in containers outside
- Conservatory and greenhouse growers keeping citrus through UK winters
- Anyone whose citrus tree has gone a long stretch without repotting and needs fed soil fertility topped up
- Gardeners who've tried a generic all-purpose feed on citrus without great results
Not the right product if you're after a hydroponic nutrient for cannabis, veg or other fast-growing hydro crops - Citrus Focus is a container fruit tree feed.
Our take
Citrus Focus does one job well - feeding potted citrus trees properly through their growing season, rather than leaving them to survive on a generic feed that wasn't designed for them. Simple dosing, clear feeding window, no guesswork about what it's actually for.
A straightforward buy if you've got citrus in pots. One we sell a lot of to gardeners rather than hydro growers, and it earns that.
