For over 40 years, Carlin Horticultural Supplies  has been deeply rooted in "The Green Industry" serving the growing needs of commercial greenhouses, nurseries, schools and landscapers with quality  commercial products from the best manufacturers worldwide. We take great pride in our family, The Maletzkes, being the sole owners of Carlin Horticultural Supplies / ProGreen Plus and we remain committed to providing our loyal customers with the best, most consistent service as a complete horticultural supplier. Our roots began with Lindor Maletzke Sr., who was the owner and head grower at Sunny Point Floral from 1900 into the 1960s. Lin and Janet Maletzke, followed in his footsteps and founded Lin's Flowerland in the 1940s, a greenhouse business in Milwaukee, Wisconsin. Together, they actively ran the nursery and in 1970 they formed Carlin Sales Corporation to distribute commercial products to an ever growing list of customers throughout the Midwest. Since that time, Carlin Horticultural Supplies  has continued to flourish. Carlin Horticultural Supplies / ProGreen Plus offers our customers four convenient locations: Milwaukee, Wisconsin - New Berlin, Wisconsin - Joliet, Illinois and St. Paul, Minnesota.
