Additional Plant Care
You can make more Philodendron selloum plants by cutting off pieces of the stems or by dividing the parent plant. Choose a healthy stem with a few leaves still attached and cut it just below a node. Take off any leaves that are close to the stem's base and leave a few leaves at the top. Dip the cut end into a rooting hormone, plant it in moist soil, and keep it warm and just slightly damp for a few weeks. To divide a plant, take the parent plant out of its pot and use a sharp, clean knife to cut the root ball into two or more pieces. Plant each piece in a new pot with potting soil and give it a good drink of water. Put the new plants in a bright but indirect light, and keep the soil moist until new growth appears.
"The Philodendron selloum contains calcium oxalate crystals, which are considered toxic if ingested by humans and pets. When chewed or ingested, the calcium oxalate crystals in the Philodendron selloum can cause irritation and discomfort in the mouth, throat, and gastrointestinal tract. Symptoms may include mouth and throat irritation, drooling, swelling, difficulty swallowing, and potential gastrointestinal distress such as vomiting or diarrhea. It's important to note that the severity of the symptoms can vary depending on the individual and the amount ingested. If someone, including a pet, ingests parts of the Philodendron selloum and exhibits severe symptoms or if you have any concerns, it's important to seek immediate medical attention or contact a poison control center. They can provide guidance specific to the situation and offer appropriate advice."
Philodendron selloum plants like to have a little bit of space between their roots, so it's best to only repot them when they've outgrown their pot. When it's time to repot a plant, choose a pot that is one or two sizes bigger than the one it's in now and has holes in the bottom for drainage. Fill the bottom of the new pot with fresh soil that drains well, and then gently take the plant out of its old pot. Check the roots and cut off any that are dead or rotten. Put the plant in the new pot and add fresh soil around the root ball. Be careful not to bury the stem too deeply. Give the plant a lot of water and put it somewhere with bright, indirect light.
The best way to prune Philodendron selloum is to use clean, sharp pruning shears to cut back any leaves that are yellow or damaged, as well as any stems that are too long or thin. It is important to cut cleanly and not hurt the tissue around the cut. Philodendron selloum plants can also be pruned to make them grow in a bushier way. To do this, cut off the top of the plant stem just above a node where new growth can start. This will make the plant grow more branches and make it fuller and more compact. You should prune the plant when it's growing, which is usually from spring to early fall. Don't prune it in the winter, when it's not growing. Philodendron selloum can also get quite big, so it's important to prune it to keep it at a size you can handle. With the right pruning, Philodendron selloum can look healthy and nice for many years and continue to grow well.
To feed a Philodendron selloum, use a balanced, water-soluble fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Before you put the fertilizer on the plant, you should water it well and dilute the fertilizer to half the recommended strength. Apply the fertilizer to the soil around the plant's base with a watering can or spray bottle. Be careful not to get any on the leaves or stem, as it can burn them. During the growing season, which usually lasts from spring to early fall, do this every two to three weeks. Don't give the plant fertilizer when it's sleeping in the winter. Too much fertilizer can hurt the plant, so it's important to follow the directions on the package and not use too much. If the leaves start to turn brown or black, cut back on how often you fertilize or make the solution less strong. You can also follow the instructions on the package and use a slow-release fertilizer once every three to four months.
Philodendron selloum plants like a soil mix that drains well and is full of nutrients. For Philodendron selloum, you should mix peat moss, perlite, and coarse sand in equal amounts. This kind of soil mix lets water drain away but keeps enough water for the plant to grow. Root rot can happen if the soil mix is too heavy or compact. Also, adding some organic matter to the soil, like compost or worm castings, can give the plant more nutrients.
