Light Requirements
The Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn thrives well in full sun and part shade environments. It requires at least six hours of direct sun per day to mature. The more sun it receives, the better it grows, but it can also tolerate shade, especially in hot climates.
Temperature Requirements
The Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn favors cold climates but can tolerate a range of temperatures. It can withstand temperatures as low as -40°F (-40°C) in winter. During the summer, the temperatures should ideally range between 60°F (15.5°C) and 80°F (26.7°C) for the plant to grow well.
Soil Requirements
Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn thrives best in moist, well-drained soils with high organic content. Though it can tolerate a range of soil types, it requires slightly acidic to neutral soils with pH levels between 5.5 and 7.5. Adding compost or other organic matter to clay soils improves aeration and drainage, while adding alkaline amendments like lime to acidic soils helps to adjust the pH to the ideal level.
Cultivation of Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn
Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn, commonly known as Mackenzie willow, is a shrubby willow native to North America. It is popularly grown as an ornamental plant, and its cultivation requires certain steps to ensure proper growth.
When cultivating Mackenzie willow, it is important to choose a location that receives full sunlight. The plant prefers moist, well-draining soil, so adding organic matter such as compost or well-rotted manure to the soil before planting can be beneficial. The ideal soil pH for the plant is between 6 and 7.5, but it can tolerate a wider range of pH levels.
Watering Needs of Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn
Mackenzie willow requires consistent watering, especially during the first year of establishment. The soil should be kept moist but not waterlogged. In hot and dry weather, the plant may require watering every 2-3 days, whereas in cooler weather, once a week may suffice. Overwatering can lead to root rot, while underwatering can cause the leaves to wilt and drop, so it is important to strike a balance.
Fertilization of Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn
Mackenzie willow benefits from regular fertilization with a balanced, slow-release fertilizer. Fertilizer should be applied in early spring before new growth begins. Too much fertilizer can lead to excessive growth, which can cause the branches to become brittle. Therefore, it is essential to use fertilizer in moderation.
Pruning of Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn
Pruning should be performed in late winter or early spring before new growth begins. The main purpose of pruning is to shape the plant and remove any dead or damaged branches. It is also essential to cut back any diseased or insect-infested wood to prevent the spread of pests or disease. Mackenzie willow can be pruned heavily to control size and shape, but care should be taken not to remove more than one-third of the tree canopy in a given year.
Propagation of Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn
Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn, commonly known as Mackenzie willow, is a deciduous shrub that can grow up to 3 meters tall. It is native to North America and can be found in wetlands, along rivers, and in other areas with moist soil. Here are the propagation methods for this plant:
Softwood cuttings
Softwood cuttings from young stems taken during the growing season can be used for propagation. The cuttings should be about 10-15 cm long and should have at least three nodes. Remove the leaves from the bottom half of the cutting, leaving 2-3 leaves at the top. Dip the cut end in rooting hormone and plant it in a pot filled with a mixture of perlite and peat moss. Keep the soil moist and the cutting should begin rooting in a few weeks.
Semi-hardwood cuttings
Semi-hardwood cuttings can also be used for propagation. Take the cuttings in mid to late summer when the wood is partially mature. Cuttings of about 15 cm long can be taken and prepare them by removing the leaves from the lower half and making a shallow cut at the bottom. Dip the cut end in rooting hormone and plant it in a medium of perlite and peat moss. The cuttings should be placed in a shaded area until roots develop.
Division
An established plant can be propagated through division. Dig up the entire plant, then separate it into smaller pieces, making sure each piece has both roots and stems. Replant the sections in a well-draining soil mixture and keep the soil moist until the plant is established.
Seeds
Seeds can also be used for propagation. Collect the seeds when the capsules are mature or purchase them from a reputable supplier. Soak the seeds in water for 24 hours. Sow the seeds in a container with a moist medium of sand, perlite and peat moss. Keep the container in a cool and shaded area until the seeds germinate, which usually takes 2-3 weeks.
Disease and Pest Management for Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn
Salix eriocephala Michx. var. mackenzieana (Hook.) Dorn, commonly known as Mackenzie willow or Arctic willow, is a shrub species that is native to the northern regions of North America. While the plant is fairly resistant to diseases and pests, there are a few common issues that can arise. Here are some tips for managing them:
Common Diseases
Cytospora canker: This fungal disease can cause bark cankers, yellowing leaves, and dieback. To manage it, promptly remove infected branches, prune away dead and diseased wood, and improve air circulation around the plant through proper pruning.
Willow scab: This fungal disease causes black spots on leaves and twigs. It can be managed by removing infected plant debris and minimizing overhead watering.
Willow blight: This bacterial disease affects newer leaves and can cause foliage to wilt and die. To manage it, remove affected leaves and prune away dead wood. Avoid overhead watering and improve air circulation through proper pruning.
Common Pests
Willow sawfly: The larvae of this pest can skeletonize leaves and cause defoliation. To manage it, prune away affected branches and handpick and destroy the larvae.
Willow leaf beetles: These pests feed on leaves and can cause defoliation. To manage them, prune away affected branches and handpick and destroy the adults and larvae.
Spider mites: These tiny pests can cause leaves to become discolored and covered in fine webbing. They are often brought on by drought stress. To manage them, keep plants adequately watered and use insecticidal soap or neem oil.
