The Q&A Archives: Gladiolus: How Far Apart Do I Plant Them?
Question: How far apart do I plant gladiolus bulbs? Preferably closest I can plant them.
Answer: Gladiolus corms should be planted four times deeper than their height and spaced 4"-6" apart, depending upon whether they are large corms or small corms. Don't overcrowd your glads or they won't perform well.
