Botanical name: Philodendron selloum
Synonyms: Thaumatophyllum bipinnatifidum, Philodendron bipinnatifidum
Common names: Lacy Tree Philodendron, Tree Philodendron, Splitleaf Philodendron
Lacy Tree Philodendron (Philodendron selloum) also called Tree Philodendron is an easy to grow non-climbing large plant which is most impressive in a large space.
The leaves are simple, large, deeply lobed, ruffle-edged, usually drooping and dark green in color. The trunk is relatively thick and woody with characteristic "eye-drop" leaf scars.
Tree Philodendron produces aerial roots from the stems and these root have an important part to play. Push them into the soil to provide moisture for the upper leaves. Flowers rarely appear under room conditions.
Philodendron selloum is also known by the botanical names Thaumatophyllum bipinnatifidum and Philodendron bipinnatifidum.
Tree Philodendron leaves can grow up to 2 ft long and are attached to long smooth petioles about 2 ft long.
According to the NASA Clean Air Study, Lacy Tree Philodendron was found to be a good indoor air cleaner of common VOCs specifically trichloethylene.
Philodendron selloum is native to South America; Brazil, Bolivia, Argentina and Paraguay.
In its tropical natural habitat, Tree Philodendron is known for its ease in covering land mass and typically spreads out its tree-like trunk from between 8-10 ft.
One common variant of Philodendron selloum is Philodendron bipinnatifidum 'Hope' also called Thaumatophyllum bipinnatifidum 'Hope' which is a shorter plant, maturing at the height of about 4 ft.
Its leaves are slightly smaller about 1.5 ft long, smooth-edged and more solid, attached to 1.5 ft long petioles.
Another common variant of Philodendron selloum is Philodendron bipinnatifidum 'Xanadu' also called Thaumatophyllum bipinnatifidum 'Xanandu' which has a mounding growth habit.
A look-alike plant but quite different from Philodendron selloum is Monstera deliciosa (Swiss Cheese Plant) whose leaves have holes rather than the seperated lobes in Philodendron selloum.

Feed Lacy Tree Philodendron every 4 weeks during the growing season with a balanced water-soluble fertilizer for lush growth.
Do not feed Tree Philodendron during the cold season as growth is minimal at this time and feeding at this time can lead to fertilizer burn.
Repot Lacy Tree Philodendron every 2-3 years during the growing period. Use a pot that is 1 size larger than the current one.
Ascertain that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot disease.
Use a heavy container to prevent the Tree Philodendron from toppling over as it can become top-heavy.
The best soil for Lacy Tree Philodendron should be rich in organic matter and free-draining to prevent it from getting soggy while providing the required nutrients like this quality potting mix available at Amazon.
Pruning Lacy Tree Philodendron involves removal of yellow and dead leaves to maintain the plant neat and minimize pest and disease infestations.
Cut back leggy stems at the beginning of the growing season to rejuvenate growth and encourage a bushy, compact growth.
Lacy Tree Philodendron (Philodendron selloum) can be propagated during the growing season from stem cuttings.
Take a stem cutting of about 4-5 in. long. from a healthy Lacy Tree Philodendron.
Insert the cutting in moist, free-draining soil and pLace the set up in a warm, well-lit place.
Maintain the soil moist until new growth has emerged. Allow the new Tree Philodendron to be well established before transplanting after which you can begin routine care.

Lacy Tree Philodendron (Philodendron selloum) problems indoors are yellow leaves, dropping leaves, brown leaf tips and edges, rotting, weeping at leaf tips, pests and diseases among others. Keep reading for more on these problems and how to fix them.
As the lower leaves of Lacy Tree Philodendron age they drop but if there is an abnormal leaf drop, the reason is sudden change of growing conditions.
Avoid moving Tree Philodendron to a new position before acclimatizing it gradually to avoid leaf drop.
If the leaves turn brown and dry before they drop, then, too high temperature is the cause of leaf drop.
Lacy Tree Philodendron prefers average warmth with a minimum of 150C. Protect it from hot draughts; keep the plant away from hot air vents or near any source of heat.
Overwatering Lacy Tree Philodendron is the reason for yellowing leaves if many leaves are affected and there are signs of wilting and rotting.
The remedy is to water Tree Philodendron thoroughly during the growing season while allowing the top 2 in. of soil to dry a little between waterings.
If there is no wilting and rotting, underfeeding is the cause of yellowing leaves in Lacy Tree Philodendron.
Remedy the situation by feeding the Tree Philodendron every 4 weeks during the growing season with a balanced water-soluble fertilizer but withhold feeding during the cold season to avoid fertilizer burn.
If only lower leaves are affected and have dark spots and new leaves are dark and small, then underwatering is the cause of the yellowing leaves in Lacy Tree Philodendron.
The solution is to water the Tree Philodendron thoroughly during the growing season while allowing the top 2 in. of soil to dry a little between waterings but never allow the soil to dry out completely.
If leaves are pale colored and have straw-colored patches the cause of yellowing leaves is too much sunlight. Keep the plant away from direct sunlight or place it in a shaded place.
If the soil is too wet, Lacy Tree Philodendron will respond with leaves weeping at the tips.
Allow the top 2 in. of soil to dry out between waterings and reduce frequency of watering to avoid getting the soil too wet.
Also ensure that the pot has a drainage hole and that the soil is free-draining to avoid getting the soil soggy (too wet).
The reason for rotting stems in Lacy Tree Philodendron is the fungal stem-rot disease which is promoted by high moisture and too little warmth.
You can save the Tree Philodendron by repotting and keeping the soil dry and warm for a period of time before watering it again. Read more on how to treat stem-rot disease in houseplants.
There are two possible causes of brown papery leaf tips and edges in Lacy Tree Philodendron. One possible cause of brown papery leaf tips and edges is dry air (low humidity).
