Helps encourage steady leaf and stem development for thriving philodendron plants.
Supports healthy root development for better water and nutrient uptake.

Leaf misting (optional)
½ tsp per pint (16 oz) of water
Every 1–2 weeks
Bright, indirect light suits them best. They tolerate medium light with slower, leggier growth, but harsh direct sun scorches leaves, especially on Pink Princess and Birkin.
Water when the top inch or two of mix is dry, then let the pot drain fully. Yellow lower leaves usually mean the soil stayed wet too long.
A chunky, well drained mix of potting soil with bark, perlite or coco chips, around pH 5.5 to 7.0. Vining types climb happily on a moss pole.
Ordinary household humidity works, though 50 percent or more brings bigger leaves. Keep plants away from heating vents and cold drafts, in rooms between 65 and 80F.
Feed every two to four weeks through spring and summer, mixing Philodendron Fertilizer into your watering, then stretch to every six weeks or so through the darker months.
Repot every year or two once roots circle the drainage holes, moving up a single pot size. Oversized pots hold water long after your philodendron has used it.
Philodendron Fertilizer is built for small, consistent feeding rather than occasional heavy doses, which is how a fast-growing foliage plant uses nutrients. Mix 1 teaspoon per quart of water and feed every 1–2 weeks through spring and summer while your philodendron is actively growing, then every 4 weeks in fall and winter. Mixing it into your regular watering keeps nitrogen arriving steadily for new leaves without the buildup that comes from infrequent strong doses. A potted philodendron depends entirely on what you feed once its mix is spent.
Leaf size comes down to steady nitrogen, enough light and, for climbing types, something to climb. Philodendron Fertilizer covers the nutrition: its 3-1-2 ratio runs nitrogen ahead of phosphorus and potassium for continuous leaf production, with calcium, magnesium and iron keeping those leaves large, deep green and glossy. Pair regular feeding with bright indirect light, and give climbers a moss pole, since many philodendrons produce larger leaves as they climb. Each new leaf should then come in larger than the last.
Yes. Philodendron Fertilizer is formulated for the genus, and heartleaf, brasil, micans, Birkin and the rarer variegated aroids all share the same foliage-first needs, so the 1 teaspoon per quart dilution and schedule work the same across them. For heavily variegated plants, bright indirect light matters most for holding the variegation; the feeding supports the green tissue that powers your philodendron. Upright types like selloum and xanadu feed the same way.
Philodendron Fertilizer is a dilute liquid feed, and dilution is what matters here. Fertilizer burn happens when concentrated salts sit against the roots: too much product in too little water. Mixed at 1 teaspoon per quart and applied every 1–2 weeks in season, the 3-1-2 formula arrives in solution at a strength the roots take up as they water. Over two-thirds of the nitrogen is nitrate, the form roots absorb directly. For recently repotted or newly acquired plants, start at half strength for the first two feedings.
New growth typically comes in greener within the first couple of weeks of regular feeding, as the nitrate nitrogen and iron in Philodendron Fertilizer reach your philodendron quickly. New leaves follow over the growing season as your plant keeps pushing new growth on a steady nitrogen supply. Plants that have sat in the same pot for over a year tend to show the most noticeable turnaround, because their mix has run out of the nutrients the formula replaces. Existing small or pale leaves won’t change; the new ones will.
