Left unpruned, plants will grow into a tangled, thorny mass of stems that fruit less well and are difficult to harvest. Training the stems onto wires has two main aims: to separate the old and new stems, so it’s easy to know which ones to prune out; and to keep these vigorous and usually thorny plants under control, so harvesting is easy ...

Under-Watering
Under-watering is one of the most frequent reasons blackberry plants don’t grow and it’s especially common if you get hot and dry summers. The best way to water blackberry plants is to only water when the top 2-4 inches of soil is dry. I check this by pushing a finger into the soil, under the plant’s drip line. When watering soak the ground at least 2 feet deep. Since over 90% of the plant’s rootsare found within the first 2 feet of soil, soaking the soil ensures the majority of the roots get...
Over-Watering
While both under and over-watering can be prevented by only watering when the soil is dry, if the soil has poor drainage it can become waterlogged and lead to issues such as root rot (more on this later). Over-watered soils are most often a result of ground that’s depressed, compact, or high in clay. Here are some quick steps to fix poorly draining soil. 1. Test 2. Amend 3. Mulch
Blackberry plants are natively from temperate climates, so they prefer cooler environments such as USDA hardiness zones 4-10. To find your hardiness zone and see if it’s compatible with blackberries, see the USDA hardiness zone map. However, this is a generalization as some varieties prefer warmer or colder zones. Climates that are too cold (below ...
Excess Nutrients
When blackberry plants get too many nutrients, their roots are chemically burned which stresses the plant and causes a decline in health. Excess nutrients are often caused by fast-release chemical fertilizers as compost isn’t potent enough. It’s more common for blackberry plants to not grow or not produce fruit because of an excess versus a lack of nutrients. If you believe you’ve over-fertilized your blackberry plant, I suggest removing as much of the fertilizer as possible via leaching. To...
A Lack of Nutrients
Source: The University of California Agriculture and Natural Resources If you haven’t fed your blackberry plant in the past several months, there’s a good chance it may be dying from a lack of nutrients. Symptoms of a lack of nutrients depend on the deficiency. For example, blackberry plants commonly get a nitrogen deficiency and get lightly colored or yellow leaves. Let’s take a look at the ideal way to prevent a lack of nutrients for your blackberry plants.
The Best Way To Fertilize Blackberry Plants
If you decide to use a chemical fertilizer, opt for one with a balanced NPK(nitrogen, phosphorus, and potassium), such as a 10-10-10. Each brand has different percentages, so follow the instructions on the label for the best results. If you’d like to see which fertilizers I recommend, check out my recommended fertilizer page. Alternatively, you can use compost. I recommend applying 1 inch of compost every 1-2 monthsunder the plant’s drip line followed by 2 inches of mulch. Keep in mind that w...
If your blackberry plant was recently planted or repotted, and its leaf growth has slowed or stunted, it’s likely due to transplant shock. Transplant shock occurs when a plant is exposed to a new environment and has to establish a new root system. In this case, the blackberry plant is stopping its canopy growth to instead regrow its roots. Avoid tr...
