Growing Elderberries

Date Posted: Sat, Apr 12 - 12:43 pm
- Hello! I was just gifted a native elderberry and I'm looking for some advice. I also plan to get another one so they can bear fruit. I've been watching tons of videos but they all seem contradictory! I live in Richmond (Battery Park) with an urban yard - it's a bit bigger than typical row house size, and bordered by a shared fence on each side. I have a few areas to plant the elderberry where it will get at least 8 hours of full sun a day. My concern is that I want to keep the bush somewhat contained - I know they can grow quite large, but is there a way to prune it so it stays under 7-8 feet but still bears fruit? And, do you have any advice on how to stay on top of root suckers? I'm not sure how far the suckers will travel, but if they head into my neighbors yard I obviously wouldn't be able to see the sprout to know where to cut the root. I also heard the roots are quite hardy, so I'm trying to consider whether to plant near a retaining wall. In the videos I'm watching the plants all seem pretty naturally contained (versus something like blackberry which gets out of control), but I want to do everything I can to help out. Hoping I can make this work! I appreciate any advice you have. If helpful, I can send a photo of my backyard. Thank you, Julie
- What a lovely gift! I hope this will be something you are able to enjoy for years to come. And you are right! You will need a second one for cross pollination. We don't typically think of elderberries being wildly invasive, so I'd expect with your awareness of the need to keep an eye out for suckers, and your desire to prune it to keep it at a reasonable size, you will be pleased with your elderberry. A couple of pruning tips: Once the plant is established (after year 1 or 2), you can cut back about 1/3 of the oldest stems to the ground each year to encourage new growth. To keep overall height in check, you can also cut the remaining stems back to your desired height (just above strong buds). Many gardeners cut stems to about 3–4 feet in early spring, which results in a bush that finishes around 6–8 feet tall by summer. Managing suckers: You’re right—elderberries do sucker from the roots and can spread over time, though they are usually less aggressive than blackberries. The suckers typically emerge within a few feet of the main plant, though they can travel farther in ideal conditions. To manage them, check around the base of the plant regularly during the growing season and cut suckers at the soil line or dig back to the root and clip at the source. You might also consider planting your elderberries in a root barrier ring—digging a trench and installing landscape edging 12–18" deep around the planting area to contain the roots. Planting near a retaining wall: Elderberry roots aren’t known for damaging structures like a retaining wall, but they are persistent. If you're concerned about suckers creeping into a neighbor’s yard or through shared fences, planting 3–5 feet away from those boundaries is a good buffer. That space also makes it easier to walk around the plant and manage pruning or harvesting. Hope this helps as you decide where to plant! Best of luck to you! Hope you will enjoy your elderberries for years to come.

Trellising Blackberries

- I am wanting to grow blackberries in containers. I have a full sun spot behind my house. Do you think galvanized feeder troughs would be a good thing in which to plant them? And was planning/thought I could trellis them on my fence - do you think that would work? Thank you
- Hello there, that sounds like a great scheme. The troughs should be fine. Galvanized containers are only a problem when they start to corrode so starting with new ones will be fine and serve you for many years. You didn't mention the type of blackberry or the height of your fence. Assuming you are using erect blackberries they will probably top out at 4-5 ft. tall. So factor that in with the height of your planters. If your trough is a foot high add in the mature height of the bushes at 5 feet. Assuming your fence is 6 feet high your good to go. Even if the fence is a bit shorter it will still work. Blackberries can get pretty tangled so you're smart to want to control them a bit with a support. Generally, you will cut down the cane after it has fruited and you've harvested. However, the pruning can vary depending on whether the plant fruits in summer or fall so just be sure to get all that information when you select a variety. It would be good to have some air circulation behind and around the plants so hopefully your fence isn't solid boards. You might wind up with some space in the front of the berries which could be a nice spot for growing herbs. Good luck with the project!
