The planting of black currants (Ribes nigrum) is currently prohibited in Massachusetts under CMR Plant Quarantines, due to the ability of this species to spread white pine blister rust, a fungus that threatens stands of white pine trees. After approximately six to eight weeks, the cutting will begin to produce shoots. Shorten the shoot after the fifth leaf by nipping out the shoot tip. This forces the plant to branch out and grow more shoots.
At the end of September, dig out the young plant and take off all its leaves. Plant it where you want your home-grown currant shrub to grow. Sep 10, 2. Clean up the cuts with a pruning saw to even them out with the base.
Use a small pruning saw to saw down any uneven cuts or cuts where you weren’t able to get all the way to the base of the bush. Aim to have no more than about in ( cm) of the branches you cut sticking up from the base of the bush%(21).
Cut the central stems out, producing the goblet shape mentioned. Trim off any shoots less than around 10cm from the soil, and remove any suckers that might be around the main stem. Cut back the main outer stem growth to about a third of their length (possibly less, depending on how neglected the plants have been!), cutting to an outward-facing bud.
The plants listed below are good choices for the rugged coastal conditions of Massachusetts. The Coastal Beach Plant List, Coastal Dune Plant List, and Coastal Bank Plant List give recommended species for each specified location (some species overlap because they thrive in various conditions).
