| Beautiful blueberries ready to pick |
- Blueberries are compact flowering bushes that bear round bluish fruit.
- They require full sun and only like moist acidic soil. Soils in Southwestern Idaho are commonly alkaline, so you must use an acidic planting mix.
- They can be planted in a landscape with amended soil or also successfully grown in a container.
- This University of Idaho link has an easy to follow description of planting needs.
Pruning, Maintenance and Fertilizer
Blueberries require little pruning; however, maintenance is required in terms of fertilization and sulfur. You’ll need to be patient.
For the first year you’ll need to strip off all the blossoms so the plant can use its energy to grow strong healthy canes for increased production.
If planting in a container, you’ll need to monitor water closely because pots dry out quickly. Blueberries like moist well drained soil but not soggy conditions.
Mulching will help keep the soil moist and limit the growth of weeds.
After the first 2 springs, you’ll want to prune off older canes to encourage new growth and fertilize with an alkalizing fertilizer (21-0-0)
Which variety to choose?

Which variety to choose?
There are many recommended cultivars which will grow in Idaho. Colorado State has
an excellent description of every one. Depending on bloom time, hardiness and height,
make your choice from two different cultivars to insure pollination. Whether you chose
to grow a Northern Highbush, Southern Highbush, Rabbiteye, Lowbush or Half-High,
your plant will produce more and larger berries when cross pollinated.
There is still time to get your blueberry plants from your favorite local nursery
