Product description
Blackberry 'Nigrum' is a vigorous, fast-growing deciduous shrub celebrated for producing incredibly heavy yields of large, deliciously sweet dark fruits. From mid-summer through to early autumn, this robust scrambling bush is heavily laden with glossy berries that are absolutely perfect for eating fresh, baking into pies, or making homemade jams. In addition to its culinary value, the beautiful white and pale pink spring flowers provide an excellent nectar source for bees, butterflies, and beneficial garden pollinators.
When establishing this hardy fruit bush, choose a location that offers full sun or partial shade in rich, fertile soil that remains moist but well-drained. It easily withstands freezing winter temperatures and requires very little ongoing maintenance once the extensive root system has successfully anchored itself into the ground. To keep the scrambling canes tidy and highly productive year after year, provide a sturdy support structure and apply a generous mulch of organic compost each spring.

Garden Plant Size Guide

Plants in larger pots can be multiple years older than their smaller counterparts with more mature root systems and foliage. This makes them able to thrive as a full size plant in your garden quicker than smaller alternatives.
The most common size of pot that garden plants come in are 9cm/1L/3L/5L this is in reference to the diameter at the top of the pot.
9cm potted plants still remain the most popular cost effective option though, they just may take a little patience to allow them to grow into full maturity once planted in your garden.

Instructions
Top Tip
To maintain a manageable size and encourage maximum fruit production, tie the long, arching canes of your Blackberry 'Nigrum' to a sturdy trellis or wire support system. Since fruit only develops on the previous year's growth, be sure to prune the older fruiting canes of your Blackberry 'Nigrum' right down to the ground every autumn.
How to Water
Provide your Blackberry 'Nigrum' with a generous soaking immediately after planting to help settle the earth and eliminate any trapped air pockets around the roots. Keep the ground consistently moist during its first growing season, noting that your Blackberry 'Nigrum' requires plenty of water as the fruits begin to swell to ensure a juicy, plump crop.
How to Plant
Select a sunny or partially shaded spot with well-drained soil and dig a hole wide enough to comfortably accommodate the root system of your Blackberry 'Nigrum'. Position your Blackberry 'Nigrum' so the base of the main stem sits perfectly level with the surrounding ground, then carefully backfill the earth and press down firmly to secure it.
