Forked Sundew Dichotoma Care Guide

Care overview

A large warm-temperate forked sundew. It may die back or form a resting crown during winter, particularly under natural seasonal light. Healthy roots normally regrow when warmth and light increase.

Light

Very bright light with several hours of direct sun or a strong grow light. Gradually acclimatise plants previously grown under weaker nursery lighting.

Watering

Keep wet using the tray method during active growth, using rainwater, distilled water or RO water. If the plant enters winter dormancy, keep the substrate damp rather than deeply flooded and never allow it to dry completely.

Humidity

Moderate humidity with good airflow. It does not require sealed terrarium humidity.

Temperature

12–30°C

Feeding and fertiliser

Do not fertilise the substrate. Allow the plant to catch insects naturally; use only species-appropriate foliar or pitcher feeding if ever needed.

Potting mix

Use nutrient-free carnivorous plant compost or a thoroughly rinsed coco coir/perlite mix. Never use fertilised houseplant compost.

Propagation

Root cuttings, division, seed and leaf cuttings

Support

The tall forked leaves may lean naturally but normally require no support. Give the roots a relatively deep pot.

Mature size

Most rosettes remain compact at roughly 5–20 cm across, while forked or climbing sundews may produce taller foliage and flower stems.

Semi-hydro suitability

Suitability depends on the plant, root condition and the chosen semi-hydro system.

Dormancy and winter growth

This warm-temperate sundew may die back to a resting crown in cooler, darker conditions, but it need not be forced dormant under suitable warmth and light. Keep the substrate damp rather than deeply flooded while growth is paused, then resume its normal tray level when active growth returns.

About this plant

Forked Sundew Dichotoma (Drosera binata var. dichotoma) is held in the Snip & Sprout permanent collection and propagated in small batches when suitable parent growth is available.

Crown, rhizome or root decline

Likely cause

Causes vary by genus and can include unsuitable moisture, poor aeration, heat, cold, damaged tissue and disease.

What to do

Inspect the affected plant and correct conditions according to the genus rather than applying one watering rule to all carnivorous plants.

Mineral or fertiliser damage

Likely cause

Many commonly grown carnivorous plants are adapted to nutrient-poor conditions and can be damaged by mineral-rich water, unsuitable compost or inappropriate fertiliser use.

What to do

Use water and growing media recommended for the genus. Rainwater, distilled water or other suitably low-mineral water is appropriate for many commonly grown types.

Poor growth

Likely cause

Insufficient light, unsuitable water, the wrong growing medium, incorrect moisture or a normal dormancy period can all reduce growth.

What to do

Check the requirements of the genus and species. Carnivorous plants do not all share the same moisture, temperature or dormancy needs.

Does Forked Sundew Dichotoma go dormant in winter?

This warm-temperate sundew may die back to a resting crown in cooler, darker conditions, but it need not be forced dormant under suitable warmth and light. Keep the substrate damp rather than deeply flooded while growth is paused, then resume its normal tray level when active growth returns.

How large can Forked Sundew Dichotoma grow indoors?

Most rosettes remain compact at roughly 5–20 cm across, while forked or climbing sundews may produce taller foliage and flower stems.

What water should I use?

Use rainwater, distilled water or reverse-osmosis water unless the individual care guidance states otherwise. Mineral-rich tap water can damage many carnivorous plants over time.
