Philodendron Hope Selloum Care
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.
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.
Thaumatophyllum Hope Selloum like things on the drier side, and we suggest using a higher than normal ratio of drainage material such as our Aeration Stones, both on the bottom of the planter and mixed into the soil. In our opinion this type of plant looks best in either shallow planters set up off the ground, planters with stands, or high planters. Almost all of our large planters feature removable drain plugs with optional matching plant saucers as well.
Standard Planter Instructions
All of our Standard Planters include a removable drainage plug to give our customers the option of drainage. While no drainage is sometimes preferred for its aesthetic simplicity, we don't recommend this option for beginners as watering mistakes can be hard to rectify.
Whether you choose to use drainage or not, we always recommend using a layer of drainage (such as our Aeration Stones) at the base of the planter. A drainage layer allows the plant's roots access to oxygen in the pockets between the drainage medium, and a lack of drainage can cause anaerobic damage to your plant.
If you decide to utilize the drainage hole for your pot, make sure to include a Plant Saucer beneath your pot to collect excess water. For most plants in standard planters, we recommend watering about once a week. Water the soil mass until water begins pooling in your Plant Saucer.
With no drainage hole, you will need to be more precise in your watering. While we would love to give you a specific measurement of water to provide for your plant, the reality is that a plant's water requirements vary wildly depending on factors such as light exposure and the overall health of the plant. You will need to learn to tell when the plant is thirsty based on how its foliage looks. Droopy foliage is usually the first sign: when your plant looks a little slumped over that's usually a visual indicator that it's thirsty.
The best solution for checking your plant's moisture level, drainage hole of not, is to use a Soil Probe to determine the moisture content of the soil at the bottom of the planter.
Self Watering Planter Instructions
The Self-Watering Planters require a deep and thorough watering of the topsoil after they are first planted. This is important because the roots of the plants first need to grow into the reservoir in order to drink from it. Water your plant from the top for two to four weeks before using the reservoir. During the dormant seasons, or for plants that have slower growing habits, consider top watering for longer.
TEST: After the initial top water period, fill the bottom water reservoir. If the water in the reservoir is absorbed into the planter, 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 plant has started drinking from the reservoir.
RESERVOIR SERVICING: Once the reservoir empties on its own, do not refill the reservoir right away. Similar to how humans need a breath of air between gulps of water, most plants require a drying out period. Allow for the reservoir to empty all the way between watering. All plants are different in their needs so the amount of time the reservoir sits empty will need to be determined, but know that for most plants this period is between 1-3 days.
From here on out, you should rarely topwater the plant while using the reservoir system. Watering from below allows the plant to drink at its own pace, and can help combat certain issues like fungus gnats by allowing the top layer of soil to dry out more. Please note that if your plant's soil dries out too much, it can impair the wicking ability of the Aeration Stones in your planter. If your soil becomes too dry, we recommend giving it a thorough watering.

Aeration Stones promote healthy root growth by creating air pockets in the soil and absorbing excess water in the basin of your planter. These porous clay stones are a natural, efficient and invaluable material to set your plant up for success. We always suggest using these when working with a planter without drainage holes.
ARS Stainless Steel Pruners
Salts and moisture from potting soil wreaks havoc on cheaper metals. Stainless steel is one of the most durable metals available on a consumer scale, and these heavy duty pruners are built to take a beating. Great for pruning jobs large and small.
Neem Oil is an all purpose insecticide, miticide, and fungicide used for organic gardening. It's systemic, which means the plant will absorb the neem oil into its circulatory system and poison pests from within. Be careful not to overuse, as this can weaken plants and cause discoloration.
Plants do poorly without air to the roots. Overwatering causes the air to be pushed out of the soil, compacting the soil around the waterlogged roots of the plant. Using the Soil Probe aerates the soil as it checks for moisture.
Watering cans come in all shapes and sizes, and the perfect one for your home is the one you're happiest living with. Look for long spouts and a container volume that's appropriate for your plant collection.
Fox Farm Ocean Forest contains all the features we look for when aiming to ensure the long term health of a plant: excellent water retention, breathability, texture, and is made from organic materials.
10-4-3 fertilizer is a great, gentle choice for indoor foliage. Simply mix this in to your watering can using the supplied directions every other week. Ensure that your plant is receiving a good amount of light, otherwise it won't have the energy to process the nutrients and burnt tips may occur on the foliage.
