How to Grow Blackberry Jam Fruit


Blackberry bushes are an ideal addition to your landscape or garden, not only for their rapid growth but for their delicious harvest, which can be created into jams, jellies, sauces and desserts. If you want to grow blackberries, it is important to find the best place in your yard to plant them, as they need full sunshine. There are some key things to keep in mind, such as preparing the soil correctly and providing proper watering and pruning.

Step 1

Make sure the area you are planting the blackberry bush in is in full sun with good drainage. The soil pH should be between 5.5 and 7 for best results. If the soil is too sandy or heavy with clay, add organic soil matter to improve the quality and aeration.

Step 2

Plan to plant the blackberry bush in the late spring season. Use a till to loosen up the top 4 inches of the soil. Discard any weeds, rocks, grass or roots.

Step 3

Dig a hole with a shovel twice as wide and a couple inches deeper then the height of the blackberry bush. Carefully set the plant down into the hole. Backfill the hole with soil.

Step 4

Water the plants immediately after you put them into the ground, then use the pruning shears or scissors to cut the plants back to about 6 inches tall. Keep in mind that during the first year, the plant will not produce any berries. Let it grow wild with no pruning, and provide about 1 inch of water per week.

Step 5

Start fertilizing the next year as soon as the last frost from spring is gone. Use a fertilizer for your blackberry bush variety, region and climate. Weed whenever you feel it is necessary.

Step 6

Add a trellis the next year to help train the berries to grow, if desired; this can be an interesting architectural element for your yard. Prune every year during the dormant winter season, cutting all the plant's trunks and canes down to the first node.

Step 7

Pick blackberries immediately after they ripen, so you can get them before any foraging animals or birds do.
