Grow Fast Acting Houseplant Food

No. You cannot burn or overdose your plants with Grow Concentrate. Synthetic plant foods are mineral salts, and too much salt scorches roots — which is why most advice tells you to use half or a quarter of what the label says. Grow Concentrate is a brewed worm casting extract, not a salt, so there is no dose to get wrong. Use it every time you water.

A quarter teaspoon per quart (32 fl oz) of water. The same for every plant in the house, whatever it is and whatever size pot it is in. There is nothing to work out per plant.

Yes, at the same dose. The usual advice is to stop, on the basis that plants go dormant. Most tropical houseplants in a heated house do not truly go dormant — they slow down and keep needing food, just less of it. A low-strength organic food handles that on its own: a plant growing slowly simply takes up less. You do not need to change the dose or the frequency.

Most customers notice healthier plants within 2 to 4 weeks of consistent use. Leaf shine and colour usually change first, and new growth follows. Slow-growing plants such as ZZ plants and snake plants take longer to show visible change than pothos or monstera.

Check light and water first. If a plant is sitting in wet soil, or it is in a dark corner, or the roots have filled the pot, feeding will not fix it and may make it look worse. Sort that out first. If the plant is stable but has not grown in months, has pale or small new leaves, or has been in the same potting mix for more than a couple of months, that is a feeding problem and this is what it is for.

Yes, when used as directed. It has been tested by independent animal toxicologists and deemed safe under normal circumstances. Store the bottle out of reach as you would any plant care product.

Grow Concentrate feeds the plant. Enrich feeds the soil. Grow is a microbe-rich extract that delivers enzymes, nutrients and microbes straight to the roots with every watering, for faster growth year round. Enrich Slow Release Plant Food is a worm casting blend that feeds slowly and strengthens roots over weeks. Most tired houseplants benefit from both, and they can be used together.

Almost certainly not from this one. That crust is a build-up of soluble salts, and it usually comes from synthetic fertilizers or from hard tap water. It is not permanent — water the pot thoroughly until it drains freely a few times and it will leach out. Grow Concentrate is not salt-based, so it does not contribute to it.

It is low odour. Most organic plant foods have a strong smell because they are made from raw organic matter; brewing the castings into an extract removes most of it. You can use it indoors without the room knowing about it.

All of them. It is formulated for plants in pots and works on monstera, pothos, philodendron, peace lily, snake plant, fiddle leaf fig, ZZ plant, calathea, rubber plant, alocasia and the rest, at the same quarter teaspoon dose. It is also safe on outdoor plants, herbs and edibles — rinse produce before eating, as you would anyway. For succulents and cacti, feed only during active growth in spring and summer.

At a quarter teaspoon per quart, the 8 fl oz makes about 190 quarts, the 42 fl oz refill makes about 1,000, and the double refill makes about 2,000.

Upright, out of direct sunlight, away from excessive heat. It does not need refrigerating.
