After planting be sure to mark the plants with plant labels so you know where they are and what varieties they are. Mulch with inches of compost of pine needles to retain moisture and prohibit weed growth. Planting Potted Plants: Set the plant in the hole at the same depth as it was growing in the pot. Backfill the hole and press firmly around the base of the planting. Water deeply. The water will seal off any air pockets around the root ball.
How to Grow Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients. Control them by either cultivating often or use a mulch to prevent their seeds from germinating.
Add mulch each year as needed. Keep plants well-watered during the growing season, especially during dry spells. Plants need about inches of rain per week during the growing season.
It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
In the spring, before leaves sprout, apply a granular fertilizer following the instructions on the label. Plants use a lot of energy in spring when growth begins, so do not let plants dry out. Remove all wild brambles near cultivated varieties to prevent virus diseases. Each year cut to the ground all but 5 or 6 of the most vigorous canes of each plant about 6 inches apart to improve fruit production. Prune these to about 30 inches to encourage lateral branches.
They will bear fruit the following year, and should be cut to the ground after harvest. Prune new shoots each year as for standard blackberries. New shoots bear fruit at the tips in fall, and further down on the cane the following spring. Cut back old canes after the second crop is harvested. Remove and destroy old canes immediately; rake up and remove fallen leaves and fruit to help prevent fungus diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
Blackberries may not need support when they are properly pruned. To prevent wind damage and to make harvesting easier, canes may be individually tied to two parallel wires strung between posts at either end of the row.
Fruit will not continue to ripen after picking so be sure to wait until fruit is ripe before picking. The fruit will ripen from red to black, but do not pick them as soon as they turn black, wait days and pick when the color has a dull appearance. These will be the sweetest fruit. Blackberries also contain other antioxidants that can help lower cholesterol and ward off cardiovascular disease. How do I determine if my blackberry plant is trailing or erect? Primocane-fruiting or semi-erect?
I got it as a gift last year. It is doing well with berries and has a really tall cane. I would like to share these delish berries with fewer being seen. I have 4 lovely, strong, healthy looking upright thornless blackberry bushes and for the past two years they flower, start blackberries, then turn brown and dry up. The plants are planted in large pots in miracle grow potted soil. Last year they were in the ground, and did the same thing, so I removed them and tried big pots.
Just dried up and brown half formed fruit. Please help. Please tell me if I can uproot and transplant into my new moving location which is about 10 hours away. What is the best way to preserve it? What season is best time to move it?
Thank you. Hi Sheryl, You can absolutely transplant your blackberry bush by your new home. Blackberry bushes grow canes that produce fruit in the second year of life, and then once finished die back.
You want to identify the canes that are in their first year of life and not currently producing flowers or fruit. They will be smaller than the fruiting canes, as well as greener. Dig up these first-year canes by the root ball in clumps, place them in a bucket or bin with a little bit of water, and drive them to your new home. Transplant on a cool day, either in the morning or evening for best results.
Good luck! We have wild blackberries on the property. The last two years I haven't been able to harvest before the wild critters got to them. Typically, there is a lot of fruit set, but the berries are very small.
We keep bees, some of the bushes are very close to the beehives, so I doubt it's a pollination problem. Should we try pruning the blackberries? I have blackberry plants that produce big, beautiful berries, but they are really tart. Is there something I can do to make them sweeter? More water, add something to the soil? It could be that the canes did not get enough water when fruit was forming or that the plants are not getting enough sun. Or it may be your variety.
You could fertilize them with an all-purpose fertilizer e. Apply 4 to 5 pounds peer 00 foot row, or for a small patch, sprinkle 3 to 4 tablespoons around each cane in early spring. I have a thorned blackberry plant that is loaded with blackberries. The problem is that they are little. What am I doing wrong? This plant is 2 years old so this is the first year producing fruit. Our sources say that there is no single reason for poor fruit set; it may be due to fungi, viruses, lack of bees, and other things, including lack of bee activity.
I have a HUGE blackberry bush in my backyard. My neighbors love me. I'm in the tipping phase but I see a few scattered blooms, should I pinch those off? I have a question as to a comment. Today I found in my row of peonies 3 or 4 small fruit producing wild grown thorny blackberry vines. Assumingely grown from a birds calling card??
How do I maintain these? Do I remove the peonies or the berry bushes from each other to gave more space? Or leave all alone and build a trellis within all for the vine to grow upon? If you want to keep them, it would be wise to transplant them out of your peony bed. Blackberries and raspberries will grow and spread like crazy, and could quickly overwhelm your peonies. How do I know if the bush is alive?

This article discusses some common blackberry fruit issues, including whitening of drupelets, drupelet reddening, insect feeding injury, canker diseases and spotted wing drosophila. Symptoms typical of severe anthracnose infection on blackberry. With both of the above physiological problems, drupelets remain full-sized and plump.
