Likely causes
Overwatering
Most likelyHow to tell: The foliage turns yellow or brown and the soil stays soggy for days. You might notice a sour or swampy smell coming from the pot.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is in a container, ensure the drainage holes are not blocked. Repot into fresh, well draining potting mix if the soil remains waterlogged.
Poor Drainage
PossibleHow to tell: Water sits on the surface of the soil long after you have finished watering. The plant looks wilted even when the soil feels damp.
What to do: Mix perlite or coarse sand into your soil to improve aeration. If the boxwood is in the ground, consider building a raised bed or adding organic matter to break up heavy clay soil.

When to worry
If the roots are black and slimy, the plant is likely beyond saving. It is normal for a few older inner leaves to drop as the plant grows.
Stopping it coming back
Only water when the top inch of soil is dry and ensure your pot has plenty of drainage holes.
