Growing a crab apple tree from seed is a relatively straightforward process, but with a few considerations that need to be taken into account. The benefits of cultivating a crab apple tree from seed are many, including a larger and more diverse selection than those available commercially. In addition, there is the satisfaction of having grown your own tree, as well as the opportunity to save money and make the garden more eco-friendly.
The first step in growing a crab apple tree from seed is to identify the type of tree desired. It is important to select a species of crab apple tree that is well-suited to your local conditions. After selecting the correct type, it is time to source a seed. Crab apple seeds can be obtained from stores, nurseries, and from mature trees in the wild. Once the seed has been collected, the next step is to prepare the seed for germination.
The seed must be dried thoroughly and, if necessary, cracked open to remove the hard outer layer and reveal the embryo inside. Planting the seed in a container filled with a moist, well-draining soil mix is recommended. Throughout the germination process, the soil should be kept at a temperature between 70-80F. After germination, increase the temperature to 70-90F and provide more light as the seedling grows.
As the young crab apple tree grows and matures, the soil should be regularly checked to ensure it is adequately draining. Re-potting and fertilizing may be necessary as the tree continues to grow in size. Pruning and training of the tree should be carried out regularly as well. Proper watering is a key element of successful crab apple tree growth and should be done every other day.
Although it can be a lengthy process, being patient and providing the correct conditions for growth will yield a beautiful and healthy crab apple tree. With patience and care, anyone can grow their own crab apple tree from seed and reap the rewards of the process.
When to Plant A Crab Apple Tree from Seed
Typically, crab apple tree seeds are planted during the fall months when their natural dormancy period begins. Planting during this time of year facilitates optimal growth and root development as the tree enters winter. During this period, the seeds should be soaked in room temperature water for 48-72 hours before being placed in the soil. This initial soaking allows the embryo inside the seed to absorb water more efficiently. Once the soil has been adequately soaked, the seeds should be placed in the soil, preferably in a darker, more shaded location.
Environmental Factors
The environment in which the trees are planted plays a key role in their growth and development. Crab apple trees will likely do best in an environment that has at least 6 hours of direct sunlight a day and when the soil temperature is between 70-90F. Additionally, the soil must be well-draining, as crab apple trees will not do well in soil that remains too moist for prolonged periods of time. In order to ensure these conditions are provided, it is recommended to check the soil regularly for drainage and temperature.
Seed Storage & Dormancy
If the desired environment is not present, the seeds can be stored for later planting. The best way to store the seeds is in a paper bag, placed somewhere dark and dry. The seeds can then be stored in the refrigerator and remain viable for up to two years. Alternatively, the seeds can be stored in a container of soil at temperatures of between 40-45F, which will put the seed into a state of dormancy until planted.
Staking & Tree Support
Once the crab apple tree is established and begins to grow, the tree will benefit from being staked or supported in order to provide structure to its frame. This is especially important during periods of high winds or heavy rainfall, when the tree’s branches might break if not supported. Additionally, staking helps to improve the overall shape of the tree as it matures.
Fertilizing & Pruning
Fertilizer is recommended for young crab apple trees. The tree should be fertilized once in the early spring and then again in the late summer. Fertilizing helps the tree to develop a strong root system and reach its maximum potential in terms of its size and growth. Pruning should also be conducted at least once per season, as it helps to eliminate any dead or disease-ridden branches, encourages more tree vigor, and contributes to its overall aesthetics.
