FAQ
Houseplant Formula is a base fertiliser for foliage and flowering houseplants grown in potting mix, including tropical plants. You can use it for plants such as monsteras, ficus, anthuriums and peace lilies. Adjust the dose and feeding frequency to how actively your plant is growing.
Garden Formula is a general-purpose base fertiliser for vegetables, herbs, flowers and ornamental plants grown in garden beds, borders or outdoor pots. It’s suitable for crops such as lettuce, cabbage, garlic, onions and leeks. For heavy-feeding crops such as tomatoes, peppers and cucumbers, choose Tomato & Chile Formula for more targeted feeding.
Yes. Tomato & Chile Formula is designed to support flowering and fruit development in heavy-feeding crops. As well as tomatoes and chile peppers, you can use it for sweet peppers, cucumbers, courgettes, aubergines, pumpkins and citrus trees.
Sea-Prime is an organic booster that combines seaweed extract and amino acids. You can use it on houseplants, vegetables, herbs, flowers, fruit plants, ornamental plants and lawns.
If you also use a Garden Gold base fertiliser, alternate the two. Use your base fertiliser at one feeding, Sea-Prime at the next, then return to your base fertiliser.
Feed with Houseplant Formula every 10–14 days while your plants are actively growing. Start with 5 ml per liter of water for young or sensitive plants. Slow-growing plants, including many succulents, generally need feeding less often. If growth stops, pause feeding until you see new growth.
During active growth, feed with Garden Formula or Tomato & Chile Formula about every 7–10 days. Adjust the dose and frequency to the plant’s needs, its stage of growth and the condition of the soil. Slow-growing plants and established plants in nutrient-rich soil may need feeding less often. Apply the diluted fertiliser around the roots, ideally when the soil is slightly moist.
Feed according to how much your plants are growing. If growth slows in winter, reduce feeding. If a plant is resting, wait until it starts growing again. Houseplants that are still putting out new growth in a bright spot or under grow lights may benefit from occasional feeding at a lower dose.
The table shows approximately how much solution you can make from each bottle size. For Houseplant Formula, Garden Formula and Tomato & Chile Formula, use 5–15 ml per liter of water. For Sea-Prime, use 5–10 ml per liter of water when watering around the roots or 2–5 ml per liter of water when applying it as a foliar spray.

Apply Houseplant, Garden and Tomato & Chile Formula through the roots. Dilute the fertiliser in water and pour it onto the soil or potting mix around the plant.
You can also apply Sea-Prime through the roots or use it as a foliar spray. For foliar application, follow the spray dose on the label and lightly mist both sides of the leaves. Spray early in the morning or later in the day, away from full sun.
Each Garden Gold base fertiliser can be used on its own. If you’d like to add Sea-Prime, alternate the two. Use your base fertiliser at one feeding, Sea-Prime at the next, then return to the base fertiliser. Prepare and apply each product separately on its own feeding day.
We make our fertilisers without vinasse and formulate them to be low in sodium. Each base feed is designed for a different use. Houseplant Formula is for indoor plants, Garden Formula is for vegetables, herbs, flowers and ornamental plants, and Tomato & Chile Formula is for heavy-feeding fruiting crops. All three contain seaweed extract and amino acids and are designed for regular feeding during active growth.
We make our fertilisers in the EU. Our base formulas use plant-based by-products from EU-grown crops.
Seaweed extract supports root development and helps plants cope with stress from heat and dry conditions. Amino acids are building blocks plants use to make proteins. Fulvic acids are a type of humic substance that helps keep nutrients available around the roots.
When feeding plants in a home with children or pets, follow the dilution and application instructions on the bottle. Keep the bottle and any mixed solution out of reach, and empty any excess feeding solution from plant saucers so children and pets can’t drink it.
For foliar application, dilute Sea-Prime according to the label and use a handheld spray bottle or pump sprayer set to a fine mist. Lightly mist both sides of the leaves.
For application to the soil, use a watering can or equipment that delivers the diluted fertiliser around the roots. For larger gardens, the Birchmeier Aquamix 1.25 V is a hose-end applicator for this purpose.
Our base products (GARDEN GOLD - Houseplants, Garden or Tomato & Chile Formulas) do not have a strong odor, perfect for indoor use.
Our seaweed extract product GARDEN GOLD - Sea-Prime Formula carries a subtle ocean scent due to its high concentration of seaweed extract.
