During the growing season, water blackberries with a drip irrigation hose for 1–2 hours, 3 times per week. During harvest season, you can increase watering frequency to 1–2 hours every day to aid fruit production. Most blackberry varieties prefer damp soil which is why drip irrigation is recommended most of the year. Healthy blackberry plants need 1–2 inches of water per week. However, this can change depending on climate and soil type.

How Much Water Do Blackberries Need Per Day?
Blackberry growers should follow the 1-2-3 rule for watering during the growing season. This means giving the plant 1–2 hours of water 2–3 times per week with a drip line or soaker hose irrigation system. Blackberries don’t need buckets of water every day. They are shallow-rooted plants so they do best with frequent, shallow watering. This is why blackberries do well in places that receive frequent light rain. If you water only once per week, the roots may dry out. So, plan to water your blackberries a few times each week.
- Remember the 1-2-3 rule: 1-2 hours of drip watering, 2-3 days a week.
- Subtract rainfall from your watering needs—light rain that moistens the first few inches of soil counts as a watering session.
- Make sure your young blackberry bush is in a deep planting hole and keep its soil moist.
Young blackberries must be grown in soil that is kept moist to a depth of 4–6 inches for the first 3 weeks after planting. This is the best depth to keep the roots moist and avoid root rot. You need to put the blackberry root ball deep in the planting hole for this period of time to ensure a sturdy anchor and fully erect blackberries.
How Long Should You Water Blackberries?
Although 1–2 hours 3 times per week is a good rule of thumb for growing blackberries, it helps to provide more water during the harvest season. Once your plant starts to grow and berries begin to ripen, water for 1–2 hours daily. Different types of blackberries may need slightly varying water times but the 1-2-3 rule is always a safe bet.
What is the Best Way to Water Blackberries?
Blackberries respond best to drip line watering or soaking lines. Use this soaker hose to water your blackberry bush. Never used a soaker hose before? It’s okay, we’ll walk you through the best way to use it on your bush.
- Using soaker hoses is the best way to water blackberry bushes.
- Arrange the soaker hose to soak the whole root area.
- Water early in the morning to maximize water retention.
Arrange the soaker hose so that water from the hose will soak the ground around the base of the blackberry plant a few inches in every direction. Water in the morning to prevent evaporation from drying up the water before it can soak into the soil and feed your plants.
Can You Overwater Blackberries?
Any plant can get overwatered and blackberries are no exception. Overwatered blackberries can drown, which causes the roots and fruit to rot. Blackberries are a drought-tolerant plant so it’s always safer to underwater them as opposed to overwatering them. Growing your blackberries on a trellis can help with their water intake as well. That said, they do need frequent watering during the growing season in order to produce fresh berries.
- Blackberries can be overwatered which can cause serious harm to the plant.
- Water regularly to ensure a harvest of fresh blackberries.
- Keep the soil surface moist but not submerged.
Other things to keep in mind are that the risk of overwatering fluctuates with the seasons. In late summer, it is harder to overwater because the heat increases the evaporation rate. However, in late winter or unusually cool summers, the risk of overwatering increases because the moisture lingers in the soil far longer.
What are the Signs of Underwatered Blackberries?
The most common sign of underwatered blackberry bushes are dried or dead leaves and dried-up berries still on the vine. This can sometimes be referred to as leaf rust. You generally want to see green leaves and fresh blackberries while they’re on the vine. A dry, cracked soil surface can be another sign of underwatering. Blackberries prefer heavy soil that is well-moistened. If the soil is not consistently damp, it may be time for more water.
- Wilting or dead leaves and dried-up berries.
- Dry and cracking soil.
- Slower plant growth.
Another telltale sign of underwatering is if your plant’s growth begins to slow significantly. Blackberries should be sprouting fresh canes and leaves in spring. If they’re not, your berries may not be getting enough water. Underwatered plants also yield a smaller crop per season than a properly watered bush. Make sure your blackberry plant gets the right amount of water for a full life.
Does a Blackberry Plant Need a Lot of Water?
Blackberry plants have about the same watering needs as other garden fruits and vegetables, including tomatoes, peppers, squash, and melons. So, if you have a soaker hose set up for your whole garden, you can water your blackberries at the same time you water everything else. The good news is that blackberry canes are drought resistant which means it’s usually safe to underwater them a bit. They do need more water during the growing season but you can easily increase the amount of water provided when this time arrives.
Should You Water Blackberries Every Day?
Blackberries don’t need to be watered every day except in specific circumstances. Some gardeners in dry regions water their blackberries daily throughout the growing season. This is done more out of specific cultural practices than necessity though.
- Unless it is harvest time and there are ripening berries on the canes, blackberries don’t need daily watering.
- If you live in a very dry climate you may need to water as frequently as once per day, but this is rare.
- Increase your watering frequency if your blackberries show signs of underwatering.
While you can increase your watering frequency to once per day once berries begin to ripen, it’s typically enough to water a couple of times per week. However, if your plant shows signs of appearing underwatered, you should definitely try watering more frequently to see if that solves the issue.
How Much Water Do Blackberry Bushes Need?
Blackberry bushes need to follow the 1-2-3 rule of watering. That’s 1-2 hours of watering a day, 2-3 days a week. This can change depending on the season or soil type but the general rule for blackberry watering is to keep the soil surface moist. Frequent applications of water in smaller amounts help to achieve this moist soil surface. Here are some other tips to remember about watering blackberries:
- Blackberries need 1-2 hours of watering, 2-3 times a week (the 1-2-3 rule).
- Soaker hoses are the best way to water blackberry bushes.
- Be aware of the signs of overwatering and underwatering—adjust your watering as needed.
Always use cold water and organic fertilizers to aid the growth of your bush. Blackberry bushes also prefer direct sunlight and moderate climates (hotter and colder regions can still produce blackberries but not as easily). Consult with your local gardening center to find what varieties of blackberries thrive in your region.
