Common Name: Philodendron atom
Botanical Name: Thaumatophyllum bipinnatifidum 'Atom'
Such an adorable, compact plant that has waves for days! The Philodendron Atom is the perfect plant to add to any indoor space. It's a low-maintenance and highly appealing houseplant that keeps the world around it calm and soothing – what's not to love?!
Philodendron atom prefers bright indirect sunlight but can live in lower light conditions. When this plant receives less than 5 hours of indirect sunlight each day, its new leaves will emerge smaller, its vines will become leggy, and vibrant colors and variegation may fade! If your home doesn't have bright indirect sunlight, you can use artificial light as a supplement. We recommend LED grow lights turned on for 8-10 hours daily!

The soil of your Philodendron atom should be watered thoroughly after the soil is almost completely dry. It indicates that it needs water when the leaves start wilting. Water more often in the growing season and reduce the frequency during winter. It is best to refrain from watering if you cannot decide whether to add more. Water your Philodendron atom slowly, with room temperature water, and constantly drain any excess water from the pot. If you notice that the soil has become compacted and or so dry that it looks like a dried-up river bed, then soak the entire root ball in a bucket of water for 10 minutes or until the water has been thoroughly absorbed into the soil. This will loosen up the compacted soil.
Philodendron atom (and all philodendrons in general) love loose, nutrient-rich potting soil. Use a soil medium that can retain moisture but also allows for draining excess water to avoid root rot. Most pre-mixed soils will suffice. Make sure there is plenty of organic matter, like coco-coir, peat moss, or shredded leaves, and avoid soil containing moisture-retaining crystals. If your soil drains too quickly, we recommend repotting it into a compost-rich soil mixture with fewer drainage materials. Learn how to create your universal soil mixture for your indoor plants!
Most household temperature ranges (65-80°F) are adequate for your Philodendron atom. Temperatures under 55℉ stunt their growth, and prolonged exposure to cold temperatures can be fatal for this tropical indoor plant.
Like most tropical indoor plants, Philodendron atom will benefit from higher humidity but will do fine in average household air. Higher humidity (over 50%) is always better for tropical houseplants like this one. Learn how to increase the humidity in the air around your indoor plants!
A Philodendron atom plant will benefit significantly from regular fertilizing because it is a fast-growing houseplant! Use a weak solution (diluted to ¼ the recommended strength) of a complete liquid fertilizer every two weeks throughout the growing season. Do not fertilize during the winter months. Sometimes this indoor plant will grow all year long. If this is the case, fertilize it during apparent foliage growth with a ¼-strength diluted liquid fertilizer, or top dress the soil with worm castings or rich compost.

Philodendron atom plants' mature height is usually around 2 to 3 feet (60 to 90 cm)! Other Philodendron plants are known to grow much larger than the Philodendron Atom. The Philodendron Atom stays compact and bushy with smaller leaves. This plant's size is more manageable as well!

- Regularly remove any damaged or dead leaves to keep your Philodendron atom plants' appearance. Pruning your plant will also assist with the size and shape of the plant!
- Only repot your Philodendron atom when the plant begins root-bound or becomes too big for its current pot.
- Remember that Philodendron atom plants like higher humidity levels, and even more in indoor settings.
