Blackberries produce juicy berries in the summer or fall. Although these hardy perennial plants are native to many parts of the world, blackberries have been mostly domesticated in North America and Europe. The blackberry cultivars sold in the nursery trade today are the result of extensive and ongoing blackberry breeding. While the fruit color of blackberries is consistently black, the fruit size and shape, yield, growth habit of the plant, and harvest season vary between cultivars.
Blackberry plants are easy to grow and long-lived with a lifespan of 15 to 40 years.
How Long Does It Take to Grow Blackberries From Seed? A Complete Guide
Growing juicy, sweet blackberries right in your own backyard is an incredibly rewarding endeavor While you can purchase blackberry plants from a nursery, starting the berries yourself from seed allows you to choose from a wider variety of cultivars and offers a more cost-effective way to expand your berry patch. However, growing blackberries from seed does require time and patience In this complete guide, we will walk through the entire process, from seed collection to transplanting seedlings, and discuss just how long it takes for blackberries to grow from seed.
Seed CollectionThe first step in growing blackberries from seed is collecting ripe berries during harvest season to extract the seeds from. Choose plump, fully mature fruits, as these will contain the healthiest, most viable seeds Once you’ve gathered your berries, mash them gently to separate the seeds from the flesh Rinse the seeds thoroughly to remove any remaining pulp or residue. Inspect the seeds and discard any that appear underdeveloped, discolored or damaged. The seeds you collect will serve as the genetic starting point for your new blackberry plants.
Stratification
Before planting, it’s crucial to stratify the blackberry seeds. Stratification is the process of exposing seeds to cold, moist conditions in order to break dormancy and enhance germination rates. To stratify, place the cleaned seeds between damp paper towels or moist peat moss and store in the refrigerator for 3-4 months. This cold period mimics winter conditions and prepares the seeds for sprouting in the spring. Skipping this essential stratification step can result in poor or sporadic germination.
Planting the Seeds
Once stratification is complete, it’s time to plant the seeds. Fill seed trays or small starter pots with a high-quality potting mix, moisten the soil, and sow 1-2 stratified seeds per container, burying them 1⁄4 inch deep. Place the containers in a warm location around 70-75°F. To lock in humidity, cover the pots with plastic wrap or use a mini greenhouse dome. Check soil moisture daily and water lightly to maintain consistent dampness. With proper conditions, germination should occur within 4-8 weeks.
Seedling Care
After the seeds sprout, remove any plastic coverings and place the seedlings under grow lights or in a sunny window. Water when the soil begins to dry out, and feed with dilute liquid fertilizer every 4-6 weeks. Monitor seedlings closely for signs of pests or disease. When plants reach 3-4 inches tall with 2-3 sets of true leaves, transplant them into larger containers or directly outdoors if the weather permits. Gradually acclimate or “harden off” transplants for 7-14 days before planting in the garden.
Planting Outdoors
Once seedlings are established and hardened off, select a planting site in full sun with well-draining, slightly acidic soil. Space plants 3-4 feet apart and dig holes to accommodate each seedling’s root ball. Plant at the same level they were growing in pots and water thoroughly after transplanting. Install a trellis or support system as plants establish. Continue watering and fertilizing regularly the first year. Mulch around plants to conserve moisture and suppress weeds.
Time to Harvest
If planted in spring, most blackberry varieties will begin to produce flowers and fruit by the second growing season. Depending on the cultivar, you can expect your first small harvest about 16-18 months after initially sowing the seeds. Production will continue increasing each year as plants mature. With proper care, homegrown blackberry plants can provide bountiful summer harvests for up to 15 years.
Soil
The soil should be slightly acidic (pH between 5.6 and 6.5) with good drainage. If the soil is wet or has a high clay content, amend it with organic matter before planting.
Keep a 1- to 2-inch layer of mulch over the root zone at all times to preserve soil moisture and suppress weeds.
Temperature and Humidity
Blackberries require a period of cold dormancy to germinate, but because of their shallow root systems, they dont do well in areas where temperatures go below zero degrees routinely. Roughly zones 5 to 9 provide the best environment for blackberries, depending on the cultivar.
Cold winter temperatures combined with wet spring soils may lead to plant death. The reverse environment of hot, dry winds is also unfavorable for blackberry growing and may result in stunted, seedy fruits.

FAQ
Do blackberries grow the first year?
For most raspberries and blackberries, fruits only grow on canes in their second (last) year of life. A few types produce a small crop of fall berries in their first year, but the big harvest comes in summer from the 2-year-old canes.
What time of the year do you plant blackberry seeds?
When should you plant blackberries? Late February or early March is the recommended time to plant these plants or root cuttings.Feb 16, 2024
Can You germinate blackberry seeds?
However, with some patience and the right method, you can successfully germinate blackberry seeds and start growing your own blackberry plants. Here is a step-by-step method for germinating blackberry seeds: Gather fresh blackberries: Start by collecting fresh blackberries from a ripe and healthy plant.
How long does a blackberry plant take to produce fruit?
Generally, blackberry plants take around 60 to 120 days to produce fruit after planting, but this can range from as little as 30 days to as long as 180 days. The variety of blackberry plant is one of the most significant factors affecting the time it takes to produce fruit.
Can you start blackberries from seed?
Well, the good news is that starting blackberries from seed is simpler than you might think. Understanding the different types of blackberry plants, such as thorned and thornless varieties, is essential for choosing the right cultivar for your garden.
How do blackberry plants grow?
Blackberry plants thrive in a wide range of growing conditions, but there are a few key factors that will help ensure their success. By providing the right combination of soil, sunlight, water, and temperature, you can create an ideal environment for blackberry plants to flourish.
What is the life cycle of a blackberry plant?
The life cycle of blackberry plants can be divided into several distinct phases, including germination, seedling establishment, vegetative growth, flowering, and fruiting. During the germination phase, which typically lasts 7-14 days, blackberry seeds sprout and develop their first set of leaves.
How do you grow blackberry seeds in winter?
This can be achieved by placing the seeds in a damp paper towel or moist soil and storing them in the refrigerator for four to eight weeks. This simulated winter period helps to mimic the natural conditions blackberry seeds experience in nature. Once the stratification period is complete, it’s time to sow the seeds.
