Philodendron Subhastatum Care

Philodendron Subhastatum

Philodendron Subhastatum doesn’t require special care and attention. You should remember to protect them from intense light and water them regularly to keep up the vibrance of their glossy leaves.

Soil

Well aerated, loose, friable, fast draining, sandy loam soil mixture is best for them. This media is mixed with perlite, coco-coir, pumice to increase drainage and worm castings as a nutrient source. Since they need to drain out the water quickly, soil mix must be prepared accordingly.

Light

They are shade loving plants. Natural, filtered light and bright indirect light are best for their proper growth. Direct exposure to sunlight may lead to leaf burn and scorches making the plant meaningless. Thus, sheer curtains or some shade cloths should be used to mellow the direct rays of light hitting on their leaves. It should be made sure that all the parts of the plant get equal amounts of light energy for their symmetrical and uniform growth.

Temperature

They are tropical shade loving plants and their growing temperature ranges from 18°C to 25°C( 64 to 77°F). The minimum temperature should not drop below 10°C. They are brought inside the house during winter to prevent their leaves’ colour from deteriorating. They must be protected from extreme weather changes.

Humidity

They need more than 50 % humidity to preserve the glossy leaves. Humidifiers can be used in places with low humidity.

Watering

Philodendron Subhastatum are water loving plants. When it comes to watering, they don’t like to dry out too much in between waterings. Unlike other Philodendron species, it sulks quickly if it’s too dry. When and how to water depends entirely on your growing conditions. The watering frequency should be increased with increasing temperature of the place you are growing it in. Wet and water-logged soil should be avoided to prevent the plant from dying. You can use your finger to check the soil texture or use a moisture metre for accuracy.

Fertilisers

Organic fertilisers, liquid kelp, deodorised fish emulsion are great fertilisers for this plant. Adding worm casting in the potting media will have enough fertiliser for it to start off in. You can fertilise it weekly during their growth phase and reduce the frequency to once a month during their resting phase. Overfeeding the plant with fertiliser is not good for their roots.

Potting And Repotting

The fine loose potting mixture should be prepared with well-draining soil added with coco-coir, worm castings, perlite and milled orchid bark to provide needed nutrition and moisture to the plant.

Repotting is practiced when the roots start growing through the holes of pot, the nutrients on the potting min gets exhausted or the plants get retarded being pot bound. It can speed up its growth on repotting. The old media is brushed off and the overgrown roots are trimmed before repotting.

Training And Pruning

Pruning is barely required for the Philodendron subhastatum. The pruning shears should be sterilised to prevent infections and illnesses from spreading. The yellow leaves are removed and repotting is done if the roots start grout out of the pot.

Cutting off too much of the plant will stunt the Philodendron Subhastatum’s growth.

Philodendron Subhastatum Propagation

This philodendron can be  propagated mostly by their stem cuttings. We can see some aerial roots growing on their stems which can be included in the stem cutting.

  • A stem cutting with at least one node and a leaf is needed for their propagation. Usually it is better to leave two nodes on the top part to ensure a better chance of its survival. There may even be aerial roots already starting to grow.
  • Use candle wax or something to seal the cut to prevent the growth of bacteria and fungi.
  • A pot is selected and filled with the potting mixture prepared beforehand.
  • The cutting is then placed in the pot with its node part submerged under soil mix.
  • Watering is done and the plant is then kept in a shaded area.
  • Water them on a daily basis. Just make sure the soil retains just the right amount of moisture.
  • It will take 2 or more months for this propagation to grow into a new plant.

Common Problems

One of the most common problems for Philodendrons is root rot due to overwatering which is indicated by yellowing of the leaves.

We can barely encounter any pests under normal growing conditions. But also it can’t hurt to keep an eye out for any mealy bug, scales, spider mites or things like that. If you notice anything, spray your plant vigorously with water first and then with surgical spirits or apply a systemic insecticide. You can rub it out mechanically and spray it with water again if the pests resist the spray.
