DOSAGE

Dosage for the Houseplant Feeding Program

15 ml = 1 tablespoon

5 ml = 1 teaspoon

Use in an alternating rhythm

Houseplant Formula
5–15 ml per 1 litre of water
Use as the base fertiliser through watering around the roots. Start with 5 ml for young, small or sensitive plants and use 8–15 ml for larger houseplants or plants in active growth.
Sea-Prime around the roots
5–10 ml per 1 litre of water
Use as alternating support through watering, for example in the feeding after Houseplant Formula.
Sea-Prime as a foliar spray
2–5 ml per 1 litre of water
Useful when you want faster extra support during active growth, recovery or stress moments. Apply a light, even mist, preferably including the underside of the leaves.

Use this program preferably in an alternating rhythm: one feeding with Houseplant Formula, the next feeding with Sea-Prime, then back to Houseplant Formula. You do not need to use both products in the same watering.

How often to use

Use during the active growing season, usually once every 1–2 weeks. In winter, or when your plants are growing slowly, use less often or apply a lighter dose.

Regular feeding at a suitable dosage works better than giving a heavy dose now and then. Always apply Houseplant Formula around the roots, preferably onto slightly moist potting soil.

Sea-Prime through roots or leaves?

For regular support, Sea-Prime can be used through watering around the roots. As a foliar spray, Sea-Prime is useful when you want faster extra support during active growth, recovery or stress moments.

Use Sea-Prime as a foliar spray preferably early in the morning or later in the day and not in full sun. Mist the leaves lightly and evenly, preferably including the underside of the leaves.

Important

Always dilute with water before use.
Shake both bottles well before use.
Use the mixed solution preferably on the same day.
Do not apply to completely dry potting soil.
Always start with a low dose for young or sensitive plants.
Do not use Sea-Prime as a foliar spray in full sun, high heat or shortly before rain.
Store cool, dark and frost-free between 5°C and 30°C.
Natural sediment may occur; this is normal for products made from natural raw materials.
