thimbleberry

Thimbleberry (Rubus parviflorus) requires regular watering to stay healthy and produce the best results. It should be watered approximately once every 1-2 weeks, depending on the climate and humidity in your region. In hot, arid conditions, water more frequently to make up for evaporation. When watering, water your Thimbleberry deeply so the water is reaching the roots and not just the top soil. Avoid over-watering as this can lead to root rot and other diseases. If the soil is too wet, it could also lead to mold growth that will cause foliage to yellow and die off. Additionally, be sure to fertilize your Thimbleberry 2-4 times during the growing season with an organic fertilizer that is low in nitrogen. By providing the right amount of water and fertilizing, you will enjoy a beautiful and healthy thimbleberry bush in your garden!

Thimbleberry (Rubus parviflorus) is best grown in full sun to partial shade. This species does best with exposure to at least 5-6 hours of direct sunlight each day. However, direct midday sunlight in the summertime can cause the plant to wilt or become sunburned. To avoid too much exposure, filtered sun may be better for the species during the hottest months. In the colder months, the plant can tolerate more sunlight. Thimbleberry will also thrive in a shadier spot, and with less sun exposure, the edible fruits it produces may be sweeter than those grown in full sun.

Thimbleberry (Rubus parviflorus) should be pruned lightly on an as needed basis. Dead or diseased canes should be removed as soon as they are found to also encourage new canes to grow. Prune out any canes that have grown too close together or are crowding other canes. Canes that have grown too tall can be pruned all the way back to the base of the plant. Thimblebbery generally should not be pruned any more than once a year, and cutting back more severely is not recommended. The best time to prune is in late fall or early spring, just before the new growth begins. Pruning at the wrong time could reduce or stop fruit production and delay flowering.
