How to Grow Heart Leaf Philodendron from Seed

Philodendron Cordatum

Philodendron planted from seed take a long time to show significant signs of growth. Because of the long waiting period, most gardeners opt for a different method altogether, but this can be a very rewarding process. If you are interested in growing a Philodendron plant from seed, you will need the following gardening equipment:

Once you have collected all the equipment required, fill the seed tray with the seed starting mix and cover the seeds with a centimeter of the seed starting mix. Spray the soil with water so that it is moist but not soggy and set the seed tray in a warm room (68 to 73 degrees Fahrenheit) that gets plenty of bright but indirect sunlight.

Cover the seed tray with its lid or with plastic wrap to hold in moisture and water the soil when it gets dry.  Transfer the seedlings to a more permanent plant container and treat them as mature plants once strong sprouts have grown

How to Propagate Heart Leaf Philodendron

Nearly all Philodendron varieties are easy to propagate via stem cuttings. This method can either be done in water or in soil. Both options are simple and straightforward and can be done during springtime pruning sessions.  

The Stem Cutting in Water Method:

If you are interested in propagating a Philodendron plant in this method, you will need the following gardening equipment:

  • A healthy 3-inch long stem that includes a petiole and at least one leaf
  • A glass filled with water (preferably rainwater, distilled water, or tap water that has set out for 24 hours or more)
  • A sterilized cutting utensil
  • A well-draining plant container
  • Well-draining potting soil
  • Plastic bag

Once you have collected all the equipment required, remove the bottom leaves from the stem and place the stem into the water. Set the glass in a room that is between 68 and 73 degrees Fahrenheit. Be sure to set the glass in a spot that receives plenty of bright but indirect sunlight.

Cover the glass with a plastic bag to hold in moisture. Change the water on a weekly basis. Once the plant has grown roots, transfer it to the plant container filled with soil and treat the plant as a mature plant.

The Stem Cutting in Soil Method:

If you are interested in propagating a Philodendron plant in this method, you will need the following gardening equipment:

  • A healthy 3-inch long stem that includes a petiole and at least one leaf
  • A sterilized cutting utensil
  • A well-draining plant container
  • Well-draining potting soil
  • Plastic bag

Once you have collected all the equipment required, remove the bottom leaves from the stem and fill the plant container with the potting soil. Place the stem into the soil and moisten the soil so that it is wet but not soggy. Set the container in a room that is between 68 and 73 degrees Fahrenheit.

Be sure to set the container in a spot that receives plenty of bright but indirect sunlight. Cover the container with a plastic bag to hold in moisture and water the plant when its soil is dry.

Heart Leaf Philodendron Growing Conditions

This tropical plant should be kept in an environment that is similar to southeastern Brazil; mainly, a hot and humid environment.

How to Plant Heart Leaf Philodendron

When kept in ideal growing conditions, Heart Leaf Philodendron plants can grow quickly. This means that they may need to be repotted every two to three years, or sooner in some cases. Repotting will provide them with new, fresh soil and room to grow. Keep an eye out for the following signs to know whether or not your plant needs repotted before two to three years has passed:

  • Compacted Soil
  • Roots that are crowded and growing into a ball formation
  • A plant that looks too big for its current container

If you are interested in repotting a Philodendron plant, you will need the following gardening equipment:

  • A plant container that is 2 inches larger in diameter than the plant’s current container
  • Well-draining potting soil
  • Water

Once you have collected all the equipment required, fill the new plant container with the well-draining potting soil and create a hole in the soil for the plant to be set into. Remove the plant from its current container (be cautious about how much you touch its root system) and dust off any excess soil from its roots. 

Set the plant into the hole in the new container and secure it in its new container by spreading the soil around its base. Lightly water the plant and set it in a warm spot with bright but indirect sunlight.

Note: Repotting should only be done on warm spring days to reduce the risk of the plant going into shock 

Heart Leaf Philodendron Potting & Soil

This Philodendron variety requires soil that is well-draining. Plan to use soil consisting of peat, sphagnum, perlite, and wood bark to provide aeration and drainage. A homemade soil consisting of 50% coco coir or peat and 50% perlite is one option, or, you can use this premade Aroid soil mix.

Don’t forget that the plant container also needs to drain off excess water. Depending on how you want to grow your vining Philodendron, you will need to choose between a hanging plant container or a sturdy plant container with drainage and a mossy pole for climbing plants.

Heart Leaf Philodendron Water Requirements

Ideally, this type of plant should be watered using the soak and dry method to limit the risk of root rot. It is a very simple method with six steps:

  1. Test the plant’s soil before watering it. It should only be watered if the top two inches of its soil is completely dry.  If it is still moist, wait another day to water it.
  2. Fill a container with water.
  3. Set the plant container in the water, but make sure the water isn’t so deep that it will overflow the lip of the container. The point of the soak and dry method is to utilize the drainage holes in the plant container to soak up water from the bottom.
  4. Let the plant soak up water for fifteen minutes.
  5. Remove the plant from the water.
  6. Set the plant in a spot where the excess water can drain from the container’s drainage holes.

This Philodendron can also be watered in a shower as long as it gets thoroughly soaked and is allowed to drain off excess water.
