How to Use

How to Use and Dosage

  • Existing Pots: Sprinkle 1 scoop (10ml) on top of the soil in Ø19cm pots and water as usual.
  • Repotting: Repot your plant as normal. 180 days after repotting mix 1 scoop (10ml) into 3L of substrate and mix it through the soil.

Tips

  • Fertilize only while the plant is growing (spring/summer). Pause during fall and winter.
  • Less is more: Never exceed the recommended dosage.
  • No need to dissolve in water—apply directly to the soil.
  • Ferns: Use half the dosage (sensitive to over-fertilising)
  • Do not use this fertiliser the first 180 days after repotting with SYBASoil!

Tropical Slow-Release Plant Food

Tropical Slow-Release Plant Food is the reliable way to keep your leafy houseplants well-fed with minimal effort. This tropical slow release fertilizer provides a consistent supply of nutrients over time, making it ideal for Monstera, Philodendron, and other fast-growing tropicals. Especially effective in mineral substrates like SYBAStones, these tropical nutrient pellets ensure plants in semi-hydro or soil-free mixes receive balanced and steady care.

Why Slow-Release Matters for Tropicals

Tropical houseplants have a reputation for being hungry growers. Standard feeding methods often give a strong boost that quickly fades, leaving plants vulnerable to nutrient gaps. Tropical controlled release fertilizer avoids that cycle by delivering tropical release nutrition gradually. This approach mirrors how plants in the rainforest receive nutrients, helping them maintain steady growth, stronger roots, and lush foliage without the stress of sudden spikes.

How It Works in Mineral Substrates

Designed for use in setups like SYBAStones, this tropical long term fertilizer breaks down slowly, releasing tropical mineral nutrients directly into the substrate. One application supplies tropical care pellets that feed for months, ensuring reliable growth in both chunky and fine houseplant blends.

Benefits of Tropical Growth Pellets

  • Steady feeding that fuels large-leaf development and strong stems
  • Supports mineral-based substrates where nutrients can wash out quickly
  • Prevents weak growth and pale foliage by offering continuous care
  • Reduces the need for frequent fertilizing, saving time and effort
  • Gentle release that avoids burning roots or overfeeding
  • Season-adjusting; Automatically feeds more in summer, less in winter

With tropical bio growth pellets, your plants receive a rhythm of nutrition that matches their natural appetite for steady energy and resilience.

Ingrediënts

Coated mineral fertiliser made in the Netherlands. Slow release plant food with its controlled release of nutrients through coating technology is the most efficient way of feeding. Because of the coating around the nutrient, you use much less compared to uncoated fertilisers, organic fertilisers and/or water-soluble fertilisers.

Another big difference is that there is little or no nutrient leaching. This is not only good for the substrate and water quality, but also for optimal uptake by the plants.

Frequently Asked Questions

How often should I re-feed?

After ~180 days or when the plant stops growing and starts showing nutrient deficiencies.

Can I combine different fertilisers?

We do not recommend mixing any of the SYBASupport Line fertilisers. Combining with Worm Castings & Lava gravel is possible.

For SYBASoil, We do still recommend waiting until the nutrients have run out (~6 months after repotting).

Can I use this product for cuttings?

We wouldn't recommend it, as too many nutrients & underdeveloped roots can harm the plant. This fertiliser is a mineral one, it's more intense.

Instead use a more gentle BIO fertiliser from SYBASupport.

Can I use this product year-round?

But don’t plants need different amounts of nutrients in summer and winter? This product helps with that!

The warmer it gets, the more nutrients will be released—less when it’s cold.

So you can apply year-round. We still would not recommend to add this plant food in the middle of winter, waiting until the early spring is ideal.

Can I use this product during the growth & flower stage?

Yes you can!

How do I store Tropical Slow-Release Plant Food?

Make sure the product is stored in a dry, dark & cool place.

Stored this way the fertiliser will stay good for years, after that it's effectiveness will start to drop.

Will Tropical Slow-Release Plant Food save my dying plant?

If a plant isn’t doing well, adding fertiliser is like giving candy to someone with a stomach ache—it might make things worse.

First, check what’s wrong: too much water, not enough light, or pests. Fix those problems before feeding it.

If lack of nutrients is the problem, your plant might look pale, grow slower, or have yellowing leaves, especially the older leaves.

That’s when fertiliser can help—but always use the right type and amount to avoid overfeeding!

What's the difference between BIO & Mineral fertilisers?

Mineral fertilisers are like fast food for plants—quick and easy but can run out fast.

Organic fertilisers are like healthy home-cooked meals—slower to work, but they make the soil better over time.

*For mineral substrates like SYBAHydro, we havent been able to find a suited bio fertiliser, that's why we sell the mineral fertilisers

How to recycle the Tropical Slow-Release Plant Food?

All SYBASupport jars & bottles are made from 100% rPet (recycled & recyclable), remove the label and bring them to your local recycling facility under recycle code 1.

The scoops can be re-used and are from PP. You can recycle them under recycle code 5.

We are actively researching a way to create our own recycling services.

What's the difference between Liquid & Slow release fertilisers?

Liquid fertilisers are like a quick drink for your plants—they get nutrients fast but need more refills.

Slow-release fertilisers are like a snack that keeps unwrapping itself, feeding your plants bit by bit over time.

Customer video review of Tropical Liquid Plant Food

J’ai commencé par acheter pour rempoter mes Orchidées. Je me suis renseigné sur la Marc énormément était étonnamment, surpris par leur différence de terreau pour chaque spécialité de plantes d’intérieur, Ce qui permet vraiment à nos plantes de libérer leur plein potentiel, car le terreau est vraiment adapté à elle. J’adore leur peau transparent qui me permet de garder un visuel sur les racines et le drainage de ceci, je collectionne de plus en plus leur terreau et j’en suis 100 % satisfaite.

Ik heb al me cactussen in Minerale Cactussen & Vetplanten Mix staan. Standaard zit er al Cactus plantenvoeding langzaam werkend in voor 6 maanden. Ik zie na 3 maanden dat ze er erg goed bij staan. Ook de wortelgroei gaat erg goed ondanks dat het nu de rustperiode is. In het voorjaar weer een beetje bij strooien dan komen zullen er weer veel bloemen komen.

Hele fijne plantenvoeding. Door het pompje kan je supergoed doseren en word je kastje waar het in staat niet vies; voorheen had ik met voeding met een schenkdop. Ondanks het omspoelen van de schenkdop en goed vastdraaien lekte de voeding alsnog en werd mijn kastje heel vies en plakkerig. Het pompje is daarom ideaal! Helemaal lekvrij, dus kastje blijft schoon. Mijn plantjes, allemaal overigens, doen het supergoed! Topspul!

Customer photo review of Orchid Slow-Release Plant Food

J’étais sceptique concernant l’Engrais pour orchidees, mais après 4 semaines, mon orchidée a refleuri. Je suis agréablement surprise, je pensais qu’elle était morte et qu'il ne restait que les hampe et les fleurs. Je l’ai trempée après avoir mis l’Engrais à libération prolongée pendant 15/20 minutes. Elle est en pleine lumière sans soleil direct et la température chez moi est de 20 degrés. Un peu humide le climat en ce moment quand-même. J’espère que mes autres orchidees refleuriront aussi. Merci Sybotanica pour vos produits et conseils.
