Some geranium cultivars can grow to tall heights

NDSU Extension-Cass County gardening expert Don Kinzler notes that "pillar geraniums" are cultivars capable of reaching heights over 6 feet when attached to a central wooden stake.
Reflecting on his past greenhouse business, Kinzler recalls growing these tall, columnar plants with his wife, Mary, noting their distinct beauty when trained on vertical supports.
While pruning would produce a stocky, well-branched stalk, Kinzler suggests maintaining the current form to preserve the tremendous beauty of the specimen.
Addressing separate inquiries, Kinzler clarifies that evergreen needles do not ruin soil acidity; rather, shallow roots deplete moisture and nutrition, leaving ground barren.
Consistent soil moisture is essential for peppers to access calcium, as fluctuations cause blossom end rot, unlike ineffective home remedies like Tums or Epsom salts.
