This maple species is adapted to wet soils and can withstand periodic flooding without harm. However, it will not grow well in consistently dry soil and may suffer from drought stress. Proper soil fertilization, aeration, and moisture management are important for successful growth and development of this plant.
Cultivation methods
Acer barbatum Michx. var. longii (Fern.) Fern. is native to the southeastern regions of the United States, including states like Georgia, Florida, and Alabama. It grows well in hardiness zones 5 to 9, preferring well-drained soils that are slightly acidic to neutral. Gardeners should ensure the planting site has ample sunlight and space for the tree to grow to its full potential.
Watering needs
Adequate watering is necessary for the healthy growth of Acer barbatum Michx. var. longii (Fern.) Fern. Young trees need more frequent watering, and the soil should be kept uniformly moist, but not waterlogged. It is essential to ensure that the soil drains entirely between watering, as consistent wetness can lead to fungus and rot. Once established, the trees can withstand moderate drought, but it is always best to keep the soil consistently moist.
Fertilization
Acer barbatum Michx. var. longii (Fern.) Fern. trees require fertilization to ensure healthy growth and proper development. A balanced fertilizer, such as a 10-10-10 or 8-8-8 blend, can be applied in early spring, just before new growth appears. Mature trees can be fertilized once in late spring or early summer. It is essential to follow the manufacturer's recommendations on the fertilizer's packaging regarding application rates and frequency.
Pruning
Pruning Acer barbatum Michx. var. longii (Fern.) Fern. trees should be done in late winter or early spring while the tree is still dormant. Dead, damaged, or diseased branches should be removed first, followed by any crossing or rubbing branches. Gardeners should ensure that the tree's central leader or main trunk is left intact and that no more than one-third of the canopy is removed at a time. It is also crucial to sterilize pruning equipment between cuts to prevent the spread of diseases.
Propagation of Acer barbatum Michx. var. longii (Fern.) Fern.
Acer barbatum Michx. var. longii (Fern.) Fern. can be propagated either from seeds or cuttings. Both methods have their advantages and disadvantages, and the choice depends on the grower's preferences and objectives.
Propagation from Seeds
Propagation from seeds is the most common method used to propagate Acer barbatum Michx. var. longii (Fern.) Fern. The seeds are available in the market or can be collected from mature trees. The following steps can be followed for seed propagation:
- Collect the seeds from mature Acer barbatum Michx. var. longii (Fern.) Fern. trees in late fall or winter when they are fully ripened.
- Soak the seeds overnight in water to soften the hard seed coat.
- Sow the seeds in a seed starting mix or peat pots and cover them with a thin layer of soil.
- Water the seeds regularly and keep them in a warm and bright environment.
- The seeds germinate in two to three weeks, and once they develop the second set of leaves, they can be transplanted to their permanent location.
Propagation from Cuttings
Propagation from cuttings is another method used to propagate Acer barbatum Michx. var. longii (Fern.) Fern., and it is a faster method than seed propagation. The following steps can be followed for cutting propagation:
- Take a 6 to 8-inch stem cutting from the current season's growth during the summer.
- Trim the leaves, and dip the bottom end of the cutting in a rooting hormone powder.
- Plant the cutting in a well-draining potting mix and water it thoroughly.
- Place the pot in a warm and bright location and keep the soil moist.
- Rooting of the cutting should occur in four to six weeks, and once it develops a strong root system, it can be transplanted to its permanent location.
Overall, Acer barbatum Michx. var. longii (Fern.) Fern. can be propagated using either seeds or cuttings. Propagation from seeds is more accessible and cost-effective, while propagation from cuttings is quicker and results in more mature plants.
