After the war there were restrictions placed on the nursery industry. Each business could only grow on a prescribed amount of land. Another restriction was our nursery industries dependence on exports to other countries. Post war countries with little money had a habit of closing down their borders. This action would cancel all orders.

Paul had a brother-in-law who lived in Mentor, Ohio USA who had often suggested that he move his family there. In 1949 Paul moved his wife, Sons Aart and Harry, and Daughter Mary to Mentor, Ohio. Aart's fiancee Margaretha de Kort arrived from The Netherlands in 1951 with her family. On September 6, 1952 Aart and Margaretha de Wit were married.

In 1955 Aart and Margaretha moved to Grand Rapids, Michigan and founded Lincoln Nurseries. Their vision was to establish a successful wholesale nursery. It all started on 15 acres of land they purchased with a $500 down payment borrowed from Margaretha's father. The first greenhouse was a plastic lean-to, kept warm with heating cables and an oil stove. The first year it produced 15,000 evergreen cuttings along with the stock they had grown in Ohio after work. The first plantings were made in 1956 - all by hand with a line and a trowel. Acquiring more land as time went on, they came to own about 200 acres and over 40,000 square feet of heated propagating houses, which produced at one time over 2.5 million cuttings, over 1 million of which was dedicated to the Taxol Cancer project. Now there are over 100 16' x 300' polyhouses for container production, over 20 heated rose houses, and 10 medium temperature houses. Field operation has slowed somewhat, but the containers have taken over. We now grow evergreens, shrubs, trees, roses, perennials, ground covers and some fruits.
