Introduction

Originally from Panama, the philodendron gigas is a velvet leaved climbing philodendron with impressive dark green leaves. They look great trained up a moss pole, and are fairly similar to the melanochrysum.

Light Needs

Bright but indirect sunlight is best for a gigas to get the best growth. They do ok back from the window a bit too.

How Often to Water

Check your plant every week, and water them when the top 50% is dry. After watering tip out any excess water, they must not sit in water logged soil as they get root rot easily.

Tip: underwater this plant rather than overwater it, they must not sit in soggy soil as they get root rot easily. Check the soil and only water if mostly dry, and make sure you don’t leave the pot sat in any excess water.

Philodendron Gigas Fertilizer

Feed a balanced feed every 3 or 4 weeks in spring and summer. Do not feed in colder months.

Soil

You want a rich well draining soil, as a cheap fix you can add 1 part perlite to 4 parts potting compost which will make for a more well draining, less root rot-prone mix. Ideally you can make a mix of equal parts orchid bark, perlite and compost. For more on Philodendron soil see our guide on what to buy or how to make your own: P h ilodendron Soil.

When To Repot

Repot them when they get root bound, be sure to check in spring so they have space to grow for the year.

Tip: give this plant a moss pole, it not only keeps it growth tidy but it will encourage it to grow larger leaves.

Philodendron Gigas Humidity

70% or even more. They are tropical plants and love a humid environment. You want to get the best out of those leaves and high humidity will help them thrive, where as they can crisp up in lower humidity levels.

Tip: Keep them humid, at least 60% in the day and they’ll be ok with a bit less at night. You can buy a humidity meter (affiliate link) to keep an eye on maximum and minimum levels.

Temperature

12-30°C (54-86°F) is ideal. They will grow quicker towards the warmer end of that range, 12°C (54°F) is a minimum temp at night or in the winter. Ideally aim for 20°C (68°F) in the day.

How To Propagate Philodendron Gigas

You can propagate a philodendron gigas with cuttings and root them in sphagnum moss, water or soil. Make sure you get at least one node and one leaf on the cutting. Let it callous over for half a day so that the open wounds heal over. Then plant it in it’s new medium, then put it in a plastic bag or box to keep the humidity high, leave a hole to keep air moving slightly. Keep it warm and humid and it it should root in a month or so. Gigas cuttings propagate quite well. Once it is rooted and starts to put out growth from the top of the plant you can pot it up into soil.
