Blackberries are excellent plants to have around your home, feed you and make your garden beautiful; when do blackberries bloom?
The blackberry is a summer berry that most people love to grow around their homes.
Blackberries have a rich, exquisite flavor that is good on its own or baked into a pie. Picking blackberries is a fun summer activity to enjoy with kids, family, and friends. In addition, not to forget the many recipes you can make from these berries.
Blackberry bushes are popularly known to produce juicy, sweet, finger-staining fruit delicately in many homes. Once they have been picked, they don’t ripen anymore, so you have to pick them when they dead ripen.
Before your blackberries produce their juicy crop, their flowers must bloom. Blackberries bloom and fruit sooner than fruit trees are planted at the same time. Blackberries took only a year to mature and produce fruits. To understand the blackberry-blooming process, read on!
When Do Blackberries Bloom?
In warm areas of USDA zone 7 and south, these berries start blooming from mid-April to early May. In cooler climates north of zone 7, blackberries begin to bloom in late May.
The right time for blackberries to bloom depends on the weather of the region where they are growing.
If you want earlier harvests, go for early-blooming varieties like the Choctaw (Rubus fruticosus), which grows in USDA zones 8 to 9, and is vigorous but thorny.
During the bloom season, blackberries attract butterflies and bees to the sweet nectar within the flowers.
You can grow blackberry bushes in USDA plant hardiness zones 5 to 10. They also grow wild along rural roads and in the woods.
When Do Blackberries Produce Fruits?
Blackberries start to ripen about 60 to 70 days after the blooms first appear, but it depends on the variety. Some varieties, like the Arapaho thornless blackberry (Rubus fruticosus) that prefer USDA zones 5 to 10, produce ripe fruit about 11 days before the Navaho(Rubus fruticosus, which does well in USDA zones 6 to 10. Navaho is the world’s first erect-growing thorn-less blackberry.
Blackberries are advantageous because they are self-fertile; they do not require a nearby male plant for pollination. It is possible to grow several blackberry plants within the same area.
Growing several plants together provides more pollen for bees to enjoy and more blooms to pollinate. More blooms in one place mean better pollination for each plant. If you don’t have a large garden to grow many blackberries, a single plant will produce blooms by itself.
If you grow different blackberries, you will notice they can cross-pollinate each other as long as they all bloom simultaneously. Different varieties can be grown in the same area and still get the benefit of cross-pollination.
When To Pick Blackberries After They Bloom
Harvesting blackberries largely depends on what kind of climate they are growing under. Blackberries are heat and frost tolerant; as a result, they can be grown virtually all over America.
Their ripening time varies based on the USDA hardiness location they are growing. In the southern United States, the blackberry harvesting time is in spring or early summer. In the Pacific Northwest, you harvest your berries late in the summer through the first frost of autumn. Throughout the rest of the United States, the prime blackberry season is July through August.
Some blackberry varieties are ever-bearing, and they produce a crop on the new growth of their old canes in the summer. They also produce another crop in the fall from the same new canes.
Blackberry harvesting must be done by hand. Pick your berries only when they are fully ripe – the color must have changed from red to black. Harvested blackberries do not continue ripening after they are harvested.
Once picked, the fruit will only last about a day after it is picked, so either eat it fresh or refrigerate it as soon as possible. Do not pick wet blackberries, as this will encourage them to squish or mold.
The harvesting season for blackberries lasts about 3 weeks, during which they should be harvested at least 2 or 3 times each week. Depending on the variety you planted, a single plant can produce between 2 to 25kg of fruit.
Post-Harvest Plant Care
After you have harvested your fruits, you will need to take care of your plant by pruning off the canes that produced the fruit. This is because they will not bear fruit again.
You can remove the floricanes for both the erect and trailing blackberry types. Once done with pruning, you are finished with your post-harvest care for your blackberry plants.
For trailing blackberry plants, you will have to remove all the strongest 6 to 12 canes that produce fruit the following season. Support the remaining canes with a trellis to be properly supported for the next growing season.
