Primocane Blackberry vs.
Floricane – Which Is Better?
There are two types of blackberries: primocanine and floristic. Both have their advantages and disadvantages, but which one is better depends on your taste preferences.
Primocane blackberry is a hybrid of two species: Primula vulgaris and Primula odorata. These berries grow well in many areas, but they tend to be smaller than other kinds of blackberries. They are not as sweet or juicy as floristic varieties, so they do not go over well with children and pets.
Some people prefer them because they look different from other kinds of blackberries.
Floricane blackberries, on the other hand, are not a hybrid. They have hundreds of different species and subspecies, many of which can be found throughout North America.
These berries are larger than primocane varieties and have a sweeter, more appealing flavor. They do well in all climates and soil conditions. The only downside to these berries is that they don’t produce new shoots every year.
When to Prune a Blackberry Vine
In general, you should prune blackberry vines during the early spring (March or April in most regions) every year. If you have a small yard, it’s better not to plant the vines on long trellises because the roots will spread too much, affecting the ability of the plant to produce the delicious fruits.
If you want the best yields, it’s best to plant the vines on stakes and trellises instead of just leaving them in the ground. This also makes it easier for you to access the canes when it comes time to harvest them.
Which Blackberry Vine Is Right For Me?
Blackberry plants are traditionally used as hedges in many English gardens. While most people are familiar with the large, juicy blackberries typically found in grocery stores, they tend to be more of a pain to grow because they are so sensitive. If you live in a temperate climate (or anywhere that experiences heavy frosts), you can grow the alpine or Mississippi varieties.
You may also want to consider growing the thornless varieties. While these vines don’t grow any thorns, they still have a slight prickly feeling when you run your hand across them. These plants are easier to care for because it is less likely that you (or anyone else who wanders into your yard or garden) will get scratched when reaching over or through the hedges.
How to Grow a Blackberry Plant
Blackberry plants prefer full sun, but can also grow in partial shade. It is important that the soil has good drainage and doesn’t hold too much water because otherwise, the roots will rot. You’ll also want to make sure that the soil is fertile.
You can plant the blackberry seeds directly into your garden or potted soil in early spring (March or April). If you’re planting the seeds in the ground, make sure that you dig a hole about twice the width of the seed and about 1 to 2 inches deep. Place the seed in the hole and lightly cover with dirt.
Water the soil until it is well saturated. It is important that you keep the soil moist, but not wet because it can cause fungus to grow.
If you’re planting the seeds in a pot, fill the pot with soil and make a small hole in the center. Place the seed into the hole and lightly cover it with soil. Finally, keep the soil damp but not wet.
If you place it in a sunny location (at least 6 hours of sunlight per day), the seed will likely sprout within a few weeks.
