Organic Chester Thornless Blackberries - 20 Seeds
Rubus fruticosus

Description: One of the most cold tolerant of all Blackberries available. Survives in locales that others cannot. Great for northern and far northern planting, or at elevations that other Blackberries can’t handle. The fruits are large in size and shape. Chester berries average 3/4 (.75) inch in diameter and 1.5 to 2 inches long. They have great shelf life, and are wonderful fresh or cooked.
Fruit: 3/4 (/275) inch by 1.5 to 2 inch long, deep Black berries that are sweet with just a hint of tartness.
Fruit Color: Deep dark Purple to Jet Black. Chester Blackberries will be bright red until they are ripe, and then will take on a glossy Purple/Blackish coloration.
USDA Zones: 2a to 8b, and to high elevation in the Northeast, Northwest and Canada
Foliage: Green, minimal autumn coloration
Blooms: White to yellow depending on soil conditions.
Soil pH: Most Blackberries prefer a slightly acidic soil pH from 6.5 to 7.3 for best results
Soil: Most soils, however, the more organic, loamy the soil in the planting location is, the better the plant will establish, grow, and produce.
Height: Height is a variable that is difficult to put a number on, you can allow the plant to grow naturally, and it may have shoots that reach up to 8 feet in height, or you may grow in a container, where the height will be about one half the total diameter of the plant.
Spacing: If you are not wild-sowing the seed, then spacing the plants out 3 feet apart in rows and a minimum of 2 feet between plants is suggested.
Growing: Sow blackberry seeds in early Fall or throughout Spring in well-drained soil that contains no less than 20 percent humus and organic matter. Blackberries prefer sandy loams amended with coarse sands or clays. As vigorous growers, Blackberries need a good amount of space, so space plants about 3 feet apart. They are not deeply rooted plants, so cover growing plants with only about 4 to 6 inches of well amended soil or compost.
Sowing Depth: Sow to a depth of 1/2 (.50) inch in well-draining, organically amended soils.
Spread: Depending on location, growing conditions and other factors, your plants can grow to spread of up to 8 feet.
Sun/Shade: Blackberry plant sin general prefer sun, and lots of it! Dappled shade can be tolerated, however there will be a drop off in fruit production as you add more shade to the plant.
Pollinator: Wind, bees, insects, hummingbirds, many other wildlife pollinators are attracted to this plant to help.
Yield: Depending on your planting location and available sunshine, however, you can expect from 3/4 (.75) pound to up to 8 or more pounds from a single plant. Container plantings do not produce as much fruit, and plants that are allowed to mature in the ground will bear more and more fruit each year,
Color: The foliage is a deep dark green that showcases immature berries as red against the green. And when the fruits mature, they stand out beautifully with deep, dark, plump Purple/Black fruits.
Watering: Water, water, water, these plants love water, and when you are establishing them, the need daily drinks, maybe sometimes twice a day if you are having heat stress. Watering is best when done by misting the plants, keeping the leaves, berries and top level of soil moist without saturating the roots. While the plant is producing fruit, increase watering. Daily watering to keep plants and berries moist will aid crop production.
Fertilizer: Compost is the best fertilizer that you can use, with some natural leaves from the growing area added as a buffer/balancer for the soil to acclimate the plant as it establishes. If you must use commercial fertilizer (We do NOT recommend this method), a 20-20-20 fertilizer will suffice. Feed blackberry bushes again when they are blooming in midsummer. Do this only if your bushes are not thriving. Apply organic matter, such as well-rotted manure, compost or leaf mold in late fall or early winter. Use 25 pounds for every 25 square feet when planting raised beds. Organic matter decomposes and adds nutrients to the soil slowly. A yearly supply of organic matter also helps the soil retain supplemental nutrients (fertilizer) and water, and it improves water drainage, a must for blackberry bushes.
Pruning: If you wish, you can prune back Blackberry plants each season, they will grow more vigorously the following season with a proper, and not too aggressive pruning. If you wish to allow them to grow in their natural state and flourish naturally, you will only have to remove any deadwood at the beginning of each growing season, and occasionally (After a storm) throughout the season. After harvest, prune old or dead canes from your Thornless blackberry plant. Make the cuts near the crown and clean up any debris from the soil. To prevent the spread of disease, burn or discard all old or dead plant material. Prune damaged or weak canes as well, leaving at least four to eight new shoots on each cane. Remove the tips of the current season’s growth to encourage lateral branching. In the spring, before new growth forms, prune lateral branches back to about 12 inches to encourage larger fruit production.
Trellising: Supporting your blackberry plant with a trellis allows air and sunlight to reach all parts of the plant. There are a variety of trellis systems that work, but a good basic design uses wire stretched between posts that are set into the ground about 20 feet apart. For semi-trailing varieties, attach one wire 3 feet up the pole and another 5 feet up. Attach a single wire about 30 inches from the ground to trellis erect varieties. Begin training the plant to climb the trellis by tying new shoots to the wire when they reach about 4 to 6 feet long. Do not bunch shoots together. If you don’t wish to trellis your plant, trim the tops of new canes during the summer months, limiting growth to about 3 to 4 feet.
Harvesting: When the Blackberries are ripe, or are just turning (As some like to harvest for a much tarter berry). Handle blackberries carefully. Try and consume them as soon as possible. Never wash or hull blackberries until you want to have them. Unwashed berries should be refrigerated immediately. Soft, overripe berries should be removed for immediate consumption. Smashed or moldy berries should be discarded. The remaining berries should be blotted dry with a paper towel. Place them in a box or spread them on a shallow plastic pan or plate. Cover with a paper towel and wrap with plastic. Fresh blackberries generally last for 2 days. But they can be frozen and enjoyed all the year round.
Harvest Timeframe: Chester Blackberries ripen in late in the season, and are normally the last to be harvested.
Comments: Blackberries in general grow equally well in fields, gardens, and container locations. Many people grow them in raised beds to better control the fruit production, water, and other environmental factors.
Health Information: High in antioxidants, healthy flavonoids, and vitamins, Blackberries are a great addition to your diet, and they are fun to eat. A good daily supply of vital nutrients is required for a glowing and perfect skin. Blackberries are rich in Vitamin A and Vitamin C. They also offer the highest levels of some antioxidants – higher than blueberries and strawberries too. The very dark color of the fruit is proof of its high antioxidant level. Anthocyanocides and polyphenols are two antioxidants found in abundance in blackberries. These help in fighting free radicals throughout your system.
