Ok, I lied. My sand cherry has suckers. Let me explain. I have a sand cherry tree in my front garden. It's very lovely–especially in the springtime, but lately, there is new growth coming up in the form of tiny little trees all around the base. These little guys are very hard to pull out–probably because they're attached to the roots of the existing tree. I turned to Anne Marie to find out how to get rid of my baby trees without harming their mama.
The new growths from the base of your sand cherry are suckers and they are still attached to the roots of the tree. Most sand cherries are shallow rooted and are prone to producing suckers since they naturally have a tendency to grow in dense thickets. They will also sucker, especially if the roots have been damaged from digging around the shrub or tree.
If you want your sand cherry to be a single trunk and not have the suckers, they can be dug up, severed from the mother plant if they have plenty of roots and given away to friends. Or, dig down to where they are attached to the root, grab hold of the sucker, twist and pull. Cutting them off at the soil level or below will not stop them from returning. Like rose suckers, the growing bud must be removed totally by twisting and pulling it out.
While I was on the subject of sand cherries, I thought I'd ask Anne Marie a question a reader had.
“Hello, I planted a sand cherry tree this spring and it's not looking good and has lots of chew holes. What should I do?”
According to Anne Marie, the sand cherry is going through a little transplanting stress and is feeling the effects of either a fungus disease called shot hole or an insect attack by any number of pests; from caterpillars like sawflies to Japanese beetles. Take a look at the leaves and if you don't see any pests on them, this is a good sign and they may have moved on. Also you don't see numerous brown spots on the leaves (the beginning of shot hole disease), Anne Marie recommends focusing on keeping the plant healthy and not worry about what caused the chew holes.
Don't fertilize the tree until it gets a little more settled, but do make sure it has enough water and that drainage is good. Also it should be planted at the same depth as it was growing in the pot, with just a small increase (2.5 cm) for mulch over the root area.
