Introduction

The philodendron gloriosum is my favorite plant I have 5 of them at the moment. They are awesome, just a big bold leaf our of the ground! I love the way they grow sideways too.

Light Needs

The gloriosum will do best with bright indirect sunlight. Do not let them get any direct sun as it will burn the leaves. They will do fine further back from the window though and mine have done just fine in mediumly lit areas.

How Often to Water

They do not want to sit in wet soil for too long, so check them once a week and only water them if the top 50% layer of soil is dry. Do not soak these your gloriosum at watering time, but give it just enough until it drips out of the bottom. Make sure you empty out any water after ten minutes so the plant does not sit in water.

Fertilizer

Use a balanced plant feed once a month in spring and summer.

Soil

The best soil mix for a gloriosum is one rich in organic matter and really well draining, with plenty of perlite.

When To Repot

Pot it up when it outgrows it’s current pot, the best time of year is in spring. If you want your gloriosum to grow large leaves you need to let it crawl, so a big pot with plenty of space for it to grow sideways is ideal. Something like a big window planter is great as the plant can develop and grows sideways. You can leave it in it’s current pot and take cuttings when it grows over the edge too, but you should really find out how great it looks when allowed to crawl and develop big leaves!

Humidity

50% is ideal for a gloriosum, you can go even higher up to 80% even. They will thrive if given 50% or more. The higher humidity the more you need to be careful of fungus on the leaves.

Temperature

The ideal temperature range for a gloriosum is 18-27°C (64-81°F). Don’t let them get too cold in winter a cold draft can really damage them.

Philodendron Gloriosum Propagation

To propagate a gloriosum wait until the new growth out the end of the plant has developed into a full leaf, then cut it off at the base, making sure to include the node the bottom.
Let the cutting heal over for 2 hours or so for the wound to heal, this will reduce the chance of the cuttings rotting.

Philodendron Gloriosum Chonk

Gloriousums are often sold as chonks, which are really small node cuttings. They are expensive plants and so sometimes the only way to get one is by buying a chonk. Often a seller will have a chonk, as naked nodes are common, all it takes is for a leaf to die back.
To grow a chonk you should place it in moist (but not soaking wet) sphagnum moss. It is important to remember that gloriosums grow sideways and not upwards, so the chonk should not be fully buried, but only half buried, and it should be horizontal – not pointing into the moss, but laid across it. Put a plastic bag around it to keep the humidity high, but leave a small hole for air. It should root quickly within a few weeks and you’ll see growth out the end soon after.

Philodendron Gloriosum Dark Form

There is some controversy about the dark form gloriosum, most that are on the web as dark form are just slight variations, or darker matured normal gloriosums that are grown with less light. The jury is still out on this, we’ll keep you posted!
