Philodendron Hope Selloum Care

Placement

PRO TIP: If you want to grow your Hope Selloum vertically, use stakes to guide its growth upward instead of outwards.

The Philodendron Hope Selloum (Philodendron bipinnatifidum), recently reclassified Thaumatophyllum bipinnatifidum or the Tree Philodendron, is a hardy native of the tropical regions of South America. In the correct conditions, their deeply lobed leaves can grow up to almost 5 feet, but indoors they can still give an immensely tropical feel to any room.

The Hope Selloum appreciates a warm humid environment, and a moderate amount of water and light. Place your Selloum in a spot where it will receive medium or bright indirect light. This plant does not do well in low light spaces. It can tolerate very high light but may need additional care.

If you are unsure of the lighting conditions in your home or office, check out our guide for how to measure light in your space.

The cut leaves of the Hope Selloum can survive for months in a vase. Change the water out once a week, and place this beauty in any surface throughout your home.

Routine Maintenance

PRO TIP: The Hope Selloum's long stems will bend toward sunlight, so rotate the plant frequently to keep it looking its fullest.

Always be sure to assess your plant’s watering needs upon receiving it. Before giving your plant a drink, it is best to check the moisture level in the soil first to ensure it isn’t moist right beneath the surface. Also, consider aerating the soil of your plant before the initial watering. We compact the soil to avoid shifting during transit, so aerating can help the soil breathe and allow moisture to be released.

Philodendrons prefer soil that is consistently lightly moist. As epiphytes with aerial roots, they are sensitive to overwatering, so they don’t want to sit in soggy soil. Typically, you shouldn’t have to water your Hope Selloum more than once a week. If the top 2 inches of the soil are dry, your plant could use a drink.

Rotate your plant periodically to ensure even growth on all sides and dust the leaves often so the plant can photosynthesize efficiently. When dusting the leaves, also take the opportunity to inspect the undersides and keep an eye out for pests.

Remember each plant is a unique living thing and may have varying needs, especially in their individual locations. Pay attention to the condition of your Hope Selloum and its watering needs and you will have a  long and happy relationship.

Frequently Asked Questions

Help! My Hope Selloum is turning yellow!

  • Most often yellowing occurs due to over or underwatering. If you see a combination of yellow and brown on the same leaf, it is often due to overwatering. If you're noticing yellow leaves, along with some brown crispy spots on additional leaves, then it could be underwatering. Check in with the soil to determine if it matches your diagnosis.

There are these weird, leafless brown growths coming off of my Philodendron. Is that normal?

  • Yes! These are called aerial roots and are totally normal. In nature, these are what help give support to the plant and allow it to climb and reach more light. The roots will not damage walls or surfaces, and you can always prune them if they get unruly.

My Philodendron has gotten way too big. What can I do?

  • Prune it back! These guys are very hardy and can handle a good trim. You can also train your Hope to grow whichever way your heart desires by using stakes and ties.

How often should I fertilize my plant?

  • In general, house plants will thrive when they are fertilized spring through fall. Fertilize once a month with an organic houseplant fertilizer, following the package instructions for dilution and administration. Greenery NYC uses an organic potting mix with a slow release fertilizer in the soil, so your plant will not need fertilizer within the first 6 months of receiving it.

How often does my plant need to be repotted?

  • For larger floor plants, we suggest repotting every 18-24 months. Typically you want to choose a potting vessel 2”- 4” larger in diameter to allow for growth. Don’t choose a pot much larger than the previous as this could drown the plants roots. If you prefer to maintain the current size of your plant, repot into the same vessel, providing new soil and trimming away some roots and foliage. Spring or summer is the ideal time to repot as the plant is at its strongest.

Standard Planter Instructions

There are two types of standard planters offered by Greenery Unlimited—those with drainage holes, and those without. Within these two categories are an array of sizes and styles to choose from. The presence of drainage holes and the size of the planted vessel both play a role in the quantity and frequency of water given to your plant.

Plants purchased in pots without a drainage hole have been set up with a built-in drainage system. A layer of Aeration Stones (porous, absorbent material made of recycled clay) has been placed beneath the soil to act as a reservoir for any excess water that flows through the soil. You will need to be slightly more cautious not to pour too much water into these containers as there is no way for the excess water to escape. We suggest slowly pouring small amounts of water in bit by bit, until you have reached the desired moisture level in the soil.

For plants potted with drainage, water until the excess begins to come out the bottom of the pot and into the catch tray.

Self Watering Container Instructions

The self-watering containers require a deep and thorough watering of the topsoil after they are first placed. This is important because the roots of the plants first need to grow into the reservoir in order to drink from it. Follow the standard planter instructions for at least four weeks, before testing the reservoir. During the dormant seasons, or for plants that have slower growing habits, consider top watering for up to ten weeks. 

TEST: After the initial top water period, fill the water reservoir until the red indicator reaches half way between the MAX and MIN line. If the indicator goes down over the first few days, it means the plant is ready for regular reservoir servicing. If not, be sure to continue top watering for a few more weeks, until the red indicator goes down, meaning the plant has started drinking from the reservoir. 

RESERVOIR SERVICING: Once the indicator goes down, do not refill the reservoir right away. Similar to how humans need a breath of air between gulps of water, almost all plants require a drying out period. Always allow for the reservoir to empty all the way, and after a drying out period of a few days, be sure to refill it until the indicator reaches the MAX line.

From here on out, you should NEVER topwater the plant while using the reservoir system. If you water from the top, it can drown the plant. In the Self Watering Container, the top layer of soil will eventually become extremely dry and hard, and may even pull away from the edges of the pot. This is not a cause for concern, but simply because the plant is drinking directly from its roots in the water reservoir. You may opt for adding fresh soil into the gaps between the soil and planter, so as to give the plant a nutrient boost. You may annually, or bi annually, top water the plant to flush the foot system. Only do so when the reservoir is empty and the plant is ready for more water.
