Tradescantia virginiana Care Indoors

To care Tradescantia virginiana indoors, provide bright indirect light, average warmth of 16-27⁰C, humidity of 50-55% and consistently moist, fertile, well-drained soil coupled with monthly feeding during the growing season.

Virginia Spiderwort care requires repotting only when extremely pot-bound as it thrives when slightly root-bound. Regular pruning is needed to keep it neat, to reduce pest and disease infestations, to encourage a bushy, compact growth and to rejuvenate growth. Keep reading for more on these growing conditions and how to achieve them.

Watering

Water your Tradescantia virginiana thoroughly in spring and summer while allowing the top 1-2 inches of soil to dry out between waterings. Maintain the soil consistently moist but not soggy to avoid yellowing and leaf drop.

Water less in fall and winter to keep the soil slightly moist as growth is minimal. Do not allow the soil to dry out completely to prevent wilting and leaf drop.

Make sure that the pot has a drainage hole and the soil is well-draining to avoid waterlogging as it can lead to root-rot and death of the plant.

Light Requirements

Tradescantia virginiana grows best in bright indirect light (dappled light). Keep it away from direct sunshine as it can lead to scorching of the leaves.

Too little light will result in yellowing and leggy growth. Therefore, if the natural light is not adequate, use full spectrum grow lights to supplement it.

Rotate the pot regularly to ensure that the plant receives light on all sides for balanced growth and prevent leggy growth.

Temperature & Humidity

Tradescantia virginiana blossoms in an average warmth of 16-27⁰C; a room temperature that is comfortable for you is ideal for this plant. Keep it away from drafts to avoid sudden changes in temperatures as they can cause reduced growth and leaf drop.

Virginia Spiderwort has no need for extra humidity; a humidity of 50-55% is ideal for this plant. However, if the air is too dry, set the pot on a wet pebble tray or use a humidifier to increase humidity. Ensure that there is proper circulation to reduce fungal diseases.

Potting Mix

The best soil for Tradescantia virginiana should be rich in organic matter and free-draining to prevent it from getting soggy while providing the required nutrients. A blend of 50% all-purpose potting soil, 25% perlite or pumice, and 25% coco coir or peat moss is ideal for this plant.

Fertilizer

Feed your Tradescantia virginiana with a balanced, liquid fertilizer every 4 weeks in spring and summer for lush growth.

Stop feeding in fall and winter as the growth is minimal and feeding at this time may lead to fertilizer burn.

Repotting

Repot your Virginia Spiderwort in the beginning of the growing season (spring to early summer), only when the plant has become extremely pot-bound.

Use a pot one size larger than the current one. Ascertain that the pot has a drainage hole to prevent the soil from getting soggy to avoid rotting. Check out these ceramic pots with drainage holes on Amazon.

Pruning & Grooming

Pruning Tradescantia virginiana involves:

• Regular removal of dead foliage to maintain the plant neat and tidy as well as minimize pest and disease infestations.


• Pinching off the growing tips to control the growth and encourage bushyness.


• Cutting back leggy stems at the beginning of the growing season to rejuvenate growth.

Occasionally clean the leaves by damp-wiping with a soft cloth to keep them clean and discourage pest and disease infestations.

Tradescantia virginiana Propagation

Tradescantia virginiana (Virginia Spiderwort) is propagated by plant divison or from stem cuttings at the beginning of the growing period.

Propagating Tradescantia virginiana by plant division

1. Water the plant thoroughly at least 1 day before to make it easier to divide and also hasten establishment.


2. Take the plant out of its pot and carefully divide it into sections. Ensure each sections has adequate roots and at least one set of leaves.


3. Select a 6 or 8 inches pot and ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting.


4. Fill the pot with free-draining soil and make a hole in the center of the pot. Ensure that the hole is slightly wider than the root base of the section.


5. Place the section in the previously made hole and lightly firm the soil around the base while taking care not to bury it too deep; maintain the section at the same soil level it was in the previous pot.


6. Wet the soil thoroughly until it comes out through the drainage hole.


7. Position the set up in a well-lit, warm place until the new plant is well established after which you can begin routine care.

Propagating Tradescantia virginiana from stem cuttings

The stem cuttings root easily so there is no need for rooting hormone.

1. Take a stem cutting from a healthy plant of about 4-6 inches and ensure it bears at least two sets of leaves.


2. Allow some time for the formation of a protective callus tissue over the cuts of the cuttings to prevent rotting.


3. Fill a rooting container with loose, free-draining soil to a depth of about 4 inches. Lightly moisten the soil.


4. With a pencil or similar object make a hole that is wider than the diameter of the cutting.


5. Carefully insert the cutting in the hole made previously to a depth of about 3 inches.


6. Place the set up in a warm, well-lit place and maintain the soil moist through out until new growth emerges.


7. Allow the new plant to be well established before transplanting to individual pots after which you can begin routine care.

Tradescantia virginiana Problems & Solutions
