Assessing the Plant Health
Before taking any action, it's crucial to assess the health of your Cassava plant. Look for signs of disease or pest infestations. Healthy plants stand a better chance of surviving the winter, so if your Cassava is struggling, address these issues first. Remove any affected leaves or stems to prevent disease from spreading during the winter.
Pruning Cassava for Winter
Pruning your Cassava plant before winter helps reduce the energy the plant needs to stay alive. Cut back the plant to about 30 cm (12 inches) tall. This focuses the plant's energy on the roots and base, which are more critical for its survival during the cold months.
Mulching the Soil around Cassava
Mulching is one of the best ways to protect Cassava during winter. Apply a thick layer of mulch, at least 10-15 cm (4-6 inches), around the base of the plant. This insulates the soil and protects the roots from freezing temperatures. Materials such as straw, wood chips, or even dried leaves work well for mulching.
Providing Shelter from Frost
Protect your Cassava plant from frost by covering it with a frost cloth or burlap. For added protection, you can construct a simple frame around the plant to hold the cloth away from the leaves. Ensure the cover reaches down to the ground to trap as much warmth as possible and prevent frost from reaching the plant.
Watering and Fertilizing in Winter
During winter, Cassava requires less water as it goes dormant. Water sparingly to keep the soil slightly moist. Overwatering can lead to root rot, which is detrimental to the plant's health. Fertilization can generally be skipped during this period as the plant's growth is significantly slowed down. Resume fertilizing in the spring as new growth begins.
