Growing your very own plum tree from scratch is a fun and fulfilling project that any gardener can undertake. Plum trees are not only beautiful but also bear delicious fruits that can be enjoyed for years to come. While buying a pre-grown plum tree from a nursery is the most common way to get started, going the full DIY route by planting a plum seed can be highly rewarding. In this post, we’ll go through the essential steps on how to grow a plum tree from seed.
Before getting started, it’s essential to understand that plum trees thrive best in USDA hardiness zones 5 through 9. This means that the locations with the best conditions for growing plum trees are places with moderately warm summers and cool winters. Be sure to check your specific location’s hardiness zone to ensure the successful growth of your plum tree.
Preparing the Plum Seed
The first step in planting a plum tree is getting your hands on a good-quality seed. To do this, after finishing a juicy, ripe plum, retrieve the seed from inside the fruit. Clean the seed thoroughly, removing any bits of pulp or debris still attached, and then dry it out overnight. Once your seed has dried, use sandpaper to remove the outer layer or coat, or alternatively, chip off one end with a nail clipper. This step is crucial as it will allow the seed to absorb moisture more effectively.
After preparing the seed, the next step is to get it to sprout, which involves a process known as “stratification.” Stratification simulates the natural conditions that a seed would experience over winter, which encourages it to germinate. To stratify your plum seed, place it in a plastic bag with a handful of damp peat moss or vermiculite. Seal the bag and put it in the refrigerator. This cold, damp environment will trick the seed into thinking it has gone through winter. Keep the seed in the refrigerator for about 6 to 8 weeks, and remember to check the bag periodically. You should see the seed sprouting a tiny root. Once this happens, your seed is ready to be planted.
How to Plant a Plum Tree Seed
Planting the sprouted plum seed is the next exciting step. Choose a location for your future plum tree. It should be a sunny spot with good drainage. Fill a small pot with potting soil until it’s about two-thirds full. Make a hole in the soil that’s deep enough for the seed’s root and place the seed in the hole with the root pointing downwards. Cover the seed with more soil, leaving the sprout exposed. Water the soil gently, ensuring it’s moist but not waterlogged. Keep the pot in a warm location with plenty of sunlight. Monitor the moisture levels of the soil and water when it feels dry to touch. After a few weeks, you should start to see your plum tree begin to grow.
Transplanting your Plum Tree Outdoors
After your plum tree has grown to about 6 inches in height in its pot, it’s ready to be transplanted outdoors. However, the timing is crucial. The best time to transplant your plum tree is in early spring or late fall when the tree is in its dormant period.
Choosing the Right Spot and Preparing the Soil
Plum trees require full sun and well-draining soil. Find a location in your garden that gets at least 6 to 8 hours of sunlight a day. Once you’ve selected the perfect spot, it’s time to prepare the soil. The soil should be well-draining but retain some moisture, and have a pH between 6.0 and 7.5. If your soil is heavy clay or sandy, improve its texture by adding organic matter such as well-rotted compost or manure.
Dig a hole in your prepared soil spot, making it deep enough to accommodate the root ball of your plum tree and twice as wide. Place the tree in the hole with the root pointing downwards and cover it with soil, ensuring the sprout is still exposed. Water it generously after planting, and continue to water it regularly, especially during dry spells, but avoid waterlogging the soil.
With the right care and attention, your plum tree should start to thrive in its new outdoor home, growing into a strong, healthy tree that will bear delicious fruits for you to enjoy in the years to come.
Watering and Fertilizing your Plum Tree
Proper watering and fertilizing are essential for the healthy growth of your plum tree. Young trees need regular watering to establish their root system. Water your plum tree deeply once a week during dry weather, ensuring the soil is moist but not waterlogged. As the tree matures, you can gradually reduce watering.
When it comes to fertilizing, a balanced fruit tree fertilizer or a slow-release granular fertilizer can be ideal. Apply the fertilizer in early spring before the onset of new growth and follow the guidelines on the product label for quantity. Avoid over-fertilizing as it can lead to overly lush growth and fewer fruits. If the leaves of your plum tree are dark green and the growth is vigorous, it’s a sign that no additional fertilizer is needed. Remember to keep the fertilizer a few inches away from the tree trunk to prevent burn. Regular mulching can also help retain soil moisture and add nutrients to the soil.
Pruning Your Plum Tree
As your plum tree grows, it’s important not to neglect its pruning. For the first year, prune your tree to promote a strong and healthy structure. Remove any damaged or diseased branches, and cut back any branches that cross over each other to form a “V” shape. In the second year, prune your plum tree to reduce its height and encourage fruit production.How big do plum trees get
Plum trees can vary significantly in size depending on the variety and growing conditions. Generally, these trees grow to a height of about 10 to 20 feet tall. Some dwarf varieties, which are suitable for small gardens or containers, can be as short as 8 to 10 feet. On the other hand, some of the larger plum tree varieties can reach heights of up to 25 feet or more. It’s important to consider the mature size of the tree when choosing a planting location, ensuring it will have enough space to grow and flourish.
How to Grow a Plum Tree in a Pot
If you lack garden space, don’t fret, as planting your plum tree in a pot can be a great alternative. First, choose a pot that’s at least twice the size of your tree’s root ball with good drainage holes. Fill the pot with a well-draining potting mix enriched with organic matter, such as compost.
Dig a hole in the center of the pot that’s deep enough for the root ball. Place the sprouted plum seed into the hole with the root pointing downwards and then cover it with soil, leaving the sprout exposed. After planting, water the soil thoroughly but avoid overwatering to prevent waterlogging.
Place the pot in a sunny location that receives at least 6 to 8 hours of sunlight each day. Just like planting in the ground, monitor the moisture levels in the pot and water when the soil feels dry to the touch. As the tree grows, you may need to upgrade to a larger pot to accommodate its growth and ensure it has enough nutrients to thrive.
Remember, potted plum trees can dry out faster than trees in the ground, so they may require more frequent watering. Likewise, they may need more regular feeding as nutrients can be quickly depleted in pots. Use a slow-release granular fertilizer and follow the product guidelines for the correct quantity.
Harvesting your Plums
The moment of reaping the fruits of your labor has finally arrived. Harvesting your plums usually occurs between late summer and early fall, but it can vary based on the variety and the growing conditions. The best way to tell if your plums are ready for harvest is by their color, size, and firmness. Ripe plums will have a full, rich color, and will feel slightly soft when gently squeezed.
To harvest, gently twist the fruit and it should easily come off the branch. Avoid pulling or tugging at the fruit as this can damage both the fruit and the tree. Remember to only pick plums that are fully ripe as they do not continue to ripen after they’ve been harvested.
Once harvested, handle your plums with care to avoid bruising. They can be eaten immediately, stored in a cool place for a few days, or used in various delightful recipes. From jams and jellies to pies and sauces, there are endless ways to enjoy your home-grown plums. Harvesting your own plums is truly a rewarding experience, encapsulating the joy and satisfaction of growing your own fruit.
Different Types of Plum Trees
There are a myriad of plum tree varieties, each with their unique characteristics, growing needs, and fruit types. Here are a few examples:
- European Plums (Prunus domestica): These trees bear oval, purple plums that are perfect for making prunes. They are hardy and can thrive in a variety of climates.
- Japanese Plums (Prunus salicina): Known for their juicy, sweet fruits that come in a range of colors from yellow to deep crimson, these are typically larger and rounder than European types. They prefer warmer climates.
- American Plums (Prunus americana): Native to North America, these plum trees produce small, sweet fruits suitable for jams and jellies. They are exceptionally hardy and can tolerate a wide range of soils.
- Damson Plums (Prunus insititia): These plum trees are known for their small, tart, blue-black fruits, traditionally used in cooking, jams, and for making sloe gin.
- Dwarf Plum Trees: Ideal for smaller spaces or container gardening, these compact trees can grow anywhere from 8 to 10 feet tall, depending on the variety.
Each plum tree variety offers unique benefits, so when choosing one, consider your climate, available space, and how you plan to use the fruit.
