Can bark mulch protect bulbs underground

Bulbs are a reliable source of colour in the garden, but they spend much of the year lying hidden beneath the soil. Protecting them during this dormant stage is vital if they are to perform well in spring. Bark mulch can offer an effective layer of protection, shielding bulbs from both weather extremes and soil disturbance.

During cold winters, a covering of bark helps to insulate the soil, reducing the risk of bulbs being damaged by deep frosts. By moderating temperature changes, the mulch prevents the soil from freezing and thawing too sharply, which can otherwise cause bulbs to shift or even rise towards the surface.

Moisture control is another benefit. Bark mulch slows evaporation, ensuring that bulbs do not dry out in periods of low rainfall, yet it also prevents the soil from becoming waterlogged by improving drainage at the surface. In addition, the mulch creates a physical barrier, discouraging weeds that would otherwise compete for nutrients once bulbs begin to grow.

As the mulch breaks down, it enriches the soil above the bulbs, creating a better growing environment year after year. Gardeners wishing to give their bulbs the best possible protection can turn to AHS LTD for bark mulches suitable for this purpose.
