Thornless Blackberry Bush - USDA Organic

1. Planting: Full sun (6 to 8 hours of sunlight daily) and well-drained soil are all the Thornless Blackberry needs to thrive, whether you plant outdoors or indoors.

To plant outside, dig a hole large enough to accommodate the Thornless Blackberry's root ball, place your plant in the hole, backfill with soil and tamp down to avoid air pockets. Finally, mulch the surrounding soil and water to settle the roots.

For indoor planting, select a pot that’s about twice the width of your plant’s shipped container, use organic soil mix and place the plant in the pot. Also, ensure that your pot has drainage holes. After your blackberry is planted, place it in front of a sunny window.

2. Watering: Thornless Blackberries are drought tolerant but need an inch of water once a week. Generally, this means soaking the surrounding soil with your hose about once per week for 30 seconds.

But if you’re not sure when to water, simply check the top 2 inches of soil for dryness for both in-ground and container-planted Blackberries. If the soil is dry here, it’s time to water. Container-planted blackberries should be watered until the water flows from the pot’s drainage holes.

3. Fertilizing: Once you see leaves on your plant, you can add some acidic organic fertilizer. When it’s fully mature, use your organic fertilizer once a year in June and again in the fall if the harvest was smaller than expected.

4. Pruning: After you’ve harvested your blackberries, prune away the canes that produced fruit. This will encourage new growth and more fruit production during your next harvest.
