Grow sweet strawberry in a vertical PVC tube is great solution for small garden or yard. Vertical planter will save you a lot of space, at the same time keep plants out of reach from garden insect pests.
Blueberries grow well when planted together with strawberries, as the strawberries provide ground cover to keep the soil cool and damp (just how blueberries like it!). Avoid planting blueberries along with tomato plants.
For more berries, you should make sure to replace your entire bed after 3-5 years. Once the strawberry plants are older than five years, they start to decrease in productivity. By replacing your beds the younger plants will be able to take over and produce lots of new strawberries.
