Brought my tomatoes back, I thought that they were gone. Mixed a 5 gal bucket and put on them and within a week they were back going strong.

25 Thriving Secrets ($4 value), the habits behind fuller, greener houseplants
Potted Plants Can't Feed Themselves
A houseplant lives within the contained ecosystem of its pot. The roots can't reach beyond it for more nutrients, and every watering can wash nutrients out through the drainage holes. When you pay attention to every new leaf, root, and growth point, precise feeding matters.
Bloom formulas: loaded with phosphorus for the fruit and flowers your pothos is never going to set
Fertilizer spikes and granular feed: release from one concentrated spot or on their own schedule, giving you less control over when nutrients reach the root zone
Water alone: doesn't replace the essential nutrients your plant uses as it grows or loses through regular watering
YARDi Indoor Core 3-1-4: mixes directly into your water for a measured, consistent application throughout the pot, making it easier to feed with intention as your plant's needs change
That's the difference between a plant that simply gets by and one that grows full, vibrant, and impossible to ignore.
Food Your Plant Can Use Today, Not Next Month
A spike puts everything in one spot and lets it out on its own schedule. A pump puts the right amount, added straight into your regular watering routine.

bolt
Already dissolved, so it's available the moment it reaches the roots
water_drop
Spread through the whole pot instead of concentrated in one hot spot
event_available
The same dose every time, whoever does the watering
Same idea, completely different delivery. Spikes miss the roots and the timing. A pump doesn't.
Pump. Pour. Done.
Your whole routine, in three steps.
STEP 1
Add
Two to four pumps into a 1 quart watering can. The pump measures the dose, no guesswork.
STEP 2
Feed
Water as usual. It's already dissolved, so the roots can use it the moment you pour.
STEP 3
Repeat
Every 2 to 3 weeks during active growth. Ease off in winter when growth slows.
Why Houseplants Slowly Stop Looking Like They Did at the Store
A nursery plant arrives full because it was grown under bright light in freshly fed soil. Put it in the corner of a living room, water it with tap water for six months, and it starts to stretch, drop its bottom leaves, and push out each new leaf a little smaller than the last.

Nothing Left in the Pot
Most potting mix contains an initial dose of nutrients. Once that's used up, a closed pot has no way to make more.
warning
Fed the Wrong Thing
A bloom or all-purpose garden formula is built around fruit and flowers, not the leaves you actually bought the plant for.
Depleted soil and the wrong formula, and the plant gets a little smaller every season instead of bigger.
The Right Nutrients, in a Form the Plant Can Use Now
Indoor Core puts plant-ready nutrition into your regular watering routine, in a ratio built around foliage.
Supports vibrant, continuous foliage growth
Feeds the moment you water, with nothing to break down first
Formulated for indoor conditions
Potassium at 4% adds support for flowering varieties
One formula for a mixed collection of flowering and foliage houseplants
Targeted indoor nutrition across a mixed collection, with added support for the flowering ones.
Why the 3-1-4 Ratio Works Indoors
Every number in the N-P-K has a job (nitrogen, phosphorus, potassium). Here's what the 3-1-4 is doing for a plant in a pot:
3%
Nitrogen (N)
The number that leads. Provides what the plant uses to push new leaves and hold a deep green.
1%
Phosphorus (P)
Kept low on purpose. Enough for roots, propagation and repot recovery, not a fruiting crop's dose.
4%
Potassium (K)
The highest number. Supports water regulation and sturdy, upright growth in dry indoor air.
Indoor Core puts that balance into one pump bottle, formulated for the plants you keep for their leaves.
