Keep it looking like the day you bought it.
Dry indoor air is tough on tropicals. Brown edges, pale leaves, cuttings that sit there doing nothing. Below, each problem comes with what’s actually in the bottle, what it does inside the plant, and why that fixes it, straight off the label.

Dry airFed with BloomThe big one in dry homes
Crispy brown edges
Dry indoor air pulls water out of thin leaf edges faster than the plant can top it up. Tips go brown, edges curl, and the plant looks tired even when you’re doing everything right.
- New leaves come out thicker and tougher, with clean edges
- Big Monstera and Alocasia leaves hold themselves up instead of flopping
- Far less tip burn through the dry winter months
Why it works
The edge is the thinnest part of the leaf and the furthest from the water supply, so it dries out and collapses first. Two things help: tougher cell walls, and a plant that handles dry-air stress better.
- Potassium silicate + monosilicic acidin Silica
Silicon is the one thing in here the plant builds into its own structure. It gets laid down in the cell walls of new growth, so new leaves come out physically stiffer and hold up better at the edges. - Southern bull kelp (Durvillaea potatorum)in Seaweed
A cold-water Southern Ocean kelp carrying natural cytokinin- and auxin-like growth compounds and potassium. Potassium is what the plant uses to open and close the pores on its leaves, which is how it manages water loss.

Water onlyRoots + SeaweedRare cuttings and props
Cuttings that root, not rot
You’ve paid good money for a node cutting and it’s been sitting in water for a month. Give it something to work with.
- First white root tips showing sooner
- More roots, thicker roots, side branches before you pot it up
- Less sulking when it moves into soil or LECA
Why it works
A cutting has no roots, so it’s living off whatever’s stored in the stem. To root it needs two things: a signal to start, and the raw material to build with.
- Root-initiating compoundsin Roots
Signal the cells at the node to start dividing and form new root tips. That’s the switch. - L-form amino acidsin Roots
Ready-made building blocks the cutting turns straight into root tissue, instead of having to make them first from stored energy it doesn’t have much of. - Fulvic acid + vitamin B1in Roots
Fulvic acid holds onto minerals and carries them across into the new root. Thiamine (B1) helps the cutting handle the stress of being cut. - Southern bull kelpin Seaweed
Natural auxin- and cytokinin-like growth compounds, the same family of signals plants use to grow roots and shoots.

When you’ll see it: roots visibly ahead in 2–3 weeks. Seaweed tints the water a light tea colour, so change it weekly.
Tap water onlyMonthly feedEvery plant, eventually
Pale, leggy and sparse
Most houseplants sit in the same potting mix for a year or more. Once it’s used up, leaves come out smaller and lighter with long bare stems between them. Seafuel goes in the watering can; Groigen is a leaf spray you mist on in the evening.
- Deeper green on new leaves
- Bigger leaves, sturdier stems, a fuller-looking plant
- A potting mix that stays alive between repots
Why it works
Pale, small leaves usually mean the potting mix has run out of usable nutrition, and nitrogen is normally the first thing to go. Nitrogen is part of chlorophyll, the green stuff, so short supply shows up as lighter, smaller leaves.
- Southern Bluefin Tuna hydrolysate, cold-processedin Seafuel and Groigen
Fish broken down into amino acids without heat, so the nitrogen, oils and proteins stay intact. Gentle, steady nitrogen in a form the plant can use, not a harsh salt. - Humic acidin Seafuel
Holds minerals in the mix in a form the roots can take up, so the feed doesn’t just wash out the bottom of the pot. - Southern bull kelpin Seafuel
Natural growth compounds and trace minerals that keep new growth even. - Sea water minerals + nori-type red algae (Porphyra)in Groigen
Trace elements and amino acids misted onto the leaf, which absorbs them directly. A second way in on top of the roots.

Clean whiteThe pricey ones
Keep the white white
The white on an Albo, Thai Con or Pink Princess has no chlorophyll. It’s the weakest part of the leaf and the first to go brown and papery in dry air, and that’s where the plant’s value is.
- Fewer brown, papery patches on the white sections
- Tougher leaves that cope better with moving and handling
- Steady growth so the plant can afford to keep its white leaves
Why it works
White sections have no chlorophyll, so they can’t make their own food. They’re fed by the green parts of the leaf, their cells are weaker, and they’re the first to dry out.
- Potassium silicate + monosilicic acidin Silica
Silicon goes into the cell walls of new leaves, white sections included, making that thin tissue tougher and less likely to go brown and papery. - Fish hydrolysate, bull kelp + humic acidin Seafuel
Steady amino-acid nitrogen and trace minerals keep the green parts working hard, so the plant can afford to carry its white.

New leaf comingThe rescue
Bring a sad plant back
Alocasias are the classic. A cold window, a move, a pest run-in or a dry week and they drop leaves or go dormant. Don’t bin it yet.
- A new leaf pushing up from the middle, often before the old ones finish yellowing
- Firm white new roots when you check the root ball
- A plant that bounces back instead of sitting dormant all winter
Why it works
When an Alocasia drops its leaves, it’s pulled back to its corm and roots to wait out the stress. It won’t push a new leaf until it has fresh roots to support one, so the roots come first.
- Root-initiating compounds + L-form amino acidsin Roots
The signal to start new roots and the building blocks to make them, so the plant rebuilds what it lost underground. - Vitamin B1 + fulvic acidin Roots
Thiamine helps buffer the stress of a move or a cold snap. Fulvic acid carries minerals into the new roots. - Southern bull kelpin Seaweed
Natural cytokinin-like compounds, the signal plants use to restart shoot growth, plus potassium to help manage water while the plant gets going again.

When you’ll see it: feed weekly until the first new leaf opens, usually 3–6 weeks. Sort any pests out first. Bloom helps recovery, it doesn’t treat bugs.
