Ideal Pot Size

Finding the ideal pot size for a houseplant depends on the size of the plant’s root ball. A 6-8 inches pot will suffice for a young Bigroot Geranium, allowing the plant ample room to grow and establish its root system.

As the plant matures and spreads, you may transfer it to a one-size bigger container to prevent overcrowding and ensure optimal growth.

Bigroot Geranium Propagation

Propagating Bigroot Geranium at home is relatively simple, and there are two primary methods: Division and Stem Cuttings. All you need are—a healthy, disease-free plant, a sterile clipper, and some well-draining potting mix.


  • Gently remove the parent plant from its pot in spring or early fall.
  • Using a clean, sharp knife or garden shears, divide the root ball into sections, each containing a healthy portion of roots and foliage.
  • Plant each division into separate pots filled with well-draining potting mix.
  • Water the divisions thoroughly and place them in a location with bright, indirect light.

Stem Cuttings:

  • Take 3-4 inch stem cuttings from the parent plant, ensuring each cutting has at least one leaf node.
  • Remove the lower leaves, leaving only the topmost leaves.
  • Dip the cut end of each cutting into rooting hormone powder to promote root development.
  • Plant the cuttings in small pots filled with a well-draining potting mix, burying the nodes 1-2 inches deep.
  • Water the cuttings thoroughly and cover the pots with clear plastic bags or place them in an indoor greenhouse to maintain high humidity.
  • Place the cuttings in a location with bright, indirect light and ensure the soil remains consistently moist but not waterlogged.

After 4-6 weeks, new growth will appear. You may cut back on watering once the plant reaches a considerable height and provide it with a suitable growing environment.

Bigroot Geranium Care


Bigroot Geraniums require bright sunlight to produce fuller blooms. Place it near the west or south-facing window to provide the same. However, if you notice the leaf edges turning brown or crisp, move it to the northern windows or filter the sunlight with a curtain.

Do remember that the plant will bloom with little to no flowers in absolute shade, so keep grow lights handy in case your home doesn’t receive direct sunlight at all.


The perennial prefers a well-draining soil mix that retains moisture without becoming waterlogged. Go for a high-quality potting mix amended with a fistful of perlite, vermiculite, or coarse sand to boost drainage. The plant is not overly fussy about soil pH, but it generally prefers a slightly acidic to neutral pH range of 6.0-7.0.


Bigroot Geranium requires consistent moisture for optimal growth. Water the plant when the top 1-2 inches of soil feels dry to the touch. Follow a weekly deep watering session by saturating the medium until water drains out of the drainage holes and letting the medium dry out a little before repeating again.

This will ensure that you don’t end up overwatering while meeting the plant’s moisture requirements. Reduce the watering frequency during the plant’s dormancy in the colder months to avoid plant shock.

Temperature & Humidity

Geranium macrorrhizum prefers moderate indoor temperatures, ideally between 65-80°F (18-26°C) during the day and slightly cooler temperatures at night. It can tolerate brief temperature fluctuations, but prolonged exposure to extreme temperatures can stress the plant.

The plant is relatively adaptable and can tolerate average indoor humidity levels. However, if your indoor environment is exceptionally dry, consider using a humidifier or placing a tray of water near the plant to increase the moisture levels in the air.


Feed your Bigroot Geranium with a balanced, water-soluble fertilizer, such as a 10-10-10 or 20-20-20 formulation, diluted to half strength, every 4-6 weeks during spring and summer to encourage robust growth and blooming.

Avoid over-fertilizing, as this will lead to excessive growth and potential nutrient imbalances. Keep from feeding the plant in the colder months when it enters a period of dormancy.


Pruning is essential for maintaining a healthy and attractive Bigroot Geranium. Remove any dead or yellowing leaves to promote airflow and prevent diseases. Also, ensure to prune back the spent flower stems to encourage a more compact growth habit and stimulate new growth.

If your geranium becomes too large or overgrown, trim back the foliage by about one-third to maintain a more manageable size. Always use sharp, sterile pruning shears or scissors to make clean cuts and minimize the risk of disease transmission.

Common Troubleshooting Tips

Keep an eye on the potential issues that may arise while Growing Bigroot Geranium Indoors. Find some common problems and their solutions below!

  • Yellowing leaves: Maintain proper moisture balance in the medium and do not let it get overly wet or dry. Allow the top 1-2 inches of soil to dry out between waterings.
  • Leggy growth: Move the plant to a location with brighter, indirect light. Avoid placing it in direct sunlight, which can scorch the leaves.
  • Leaf scorch or Browning: Relocate the plant to an area with filtered or indirect light to prevent further damage.
  • Failure to Bloom: Ensure the plant receives enough bright, indirect light to encourage flowering. Reduce the frequency and strength of fertilization to avoid excessive growth at the expense of flowering.
  • Pests: Inspect the plant regularly for pests such as aphids, mealybugs, or spider mites and treat the affected areas with insecticidal soap, neem oil, or horticultural oil spray. Isolate the affected plant to prevent the spread of pests to other plants.
  • Root Rot: Improve the soil mix’s drainage by adding perlite, vermiculite, or coarse sand. Ensure the pot has drainage holes and avoid overwatering.
  • Powdery Mildew or Other Fungal Diseases: Prune the plant to remove dead or crowded growth and maintain adequate spacing between plants to improve air circulation. Avoid misting the plant and reduce humidity levels if necessary.
