Algal Stem Blotch: Protect Your Blueberry Bushes!
Worried about brown or black spots on your blueberry stems? It might be algal stem blotch, a sneaky disease that can strangle your plants. But fear not, fellow berry lover! Here’s the lowdown on this foe and how to keep your blueberries thriving:
What is it?
Unlike most plant diseases, algal stem blotch isn’t caused by a fungus, but by a sneaky parasitic alga called Cephaleuros virescens. It hides under the stem’s surface, causing red blotches that turn brown or black. As it grows, it disrupts the plant’s flow of nutrients and water, leaving your blueberries struggling.

This alga loves humid, stagnant air. Think: dense plantings, frequent overhead watering, and rainy weather. These conditions create a cozy haven for it to thrive and wreak havoc on your blueberry patch.
How to save your berries:
1. Give them some air! Thin out crowded plants and prune for good air circulation. Think of it as creating a breezy spa for your blueberries.
2. Ditch the overhead shower. Water directly at the base of your plants. This keeps the stems dry and less inviting for the alga.
3. Be a vigilant plant detective! Regularly inspect your blueberries for any suspicious discoloration on the stems. Early detection is key!
4. Snip, snip, save! See any infected stems? Prune them off promptly and dispose of them properly. Don’t let the alga hitch a ride to other plants!
5. Consider a fungicide shield. In severe cases or as a preventive measure, consult your local agricultural experts for fungicides specifically designed for blueberries.
Remember: Consistent monitoring and quick action are your best weapons against algal stem blotch. By following these tips, you can keep your blueberry bushes healthy and bursting with delicious berries!
