Water Beta macrocarpa consistently to maintain moist, but not waterlogged, soil. Allow the top 2-3 cm of soil to dry out between waterings, especially during warmer periods.

Reduce watering in cooler months to prevent root rot. Ensure good drainage to avoid fungal issues.

Pruning is generally not required for Beta macrocarpa, as it is grown for its root or foliage. Remove any damaged or diseased leaves promptly to maintain plant health.

If grown for ornamental purposes, light trimming can be done to maintain shape, but avoid heavy pruning which can stress the plant.

Beta macrocarpa is typically propagated by seed. Sow seeds directly into the ground or in pots in early spring after the danger of frost has passed. Seeds germinate best in warm soil (around 20-25°C).

Thin seedlings to the desired spacing once they have a few true leaves.

As Beta macrocarpa is often grown as an annual or for its root harvest, repotting is rarely necessary unless growing in containers for extended periods.

If the plant becomes root-bound in a pot, transplant it into a larger container in spring. Use a well-draining potting mix.
