Dennis Crum Is The 2013 Head Grower Of The Year

Dennis Crum of Four Star Greenhouse, Inc.

Dennis Crum is a grower’s grower. The 21-year mainstay at Four Star Greenhouse spends a lot of his time on the telephone answering culture calls and flying around the country to work with growers, help them plan spring production, review their seasons and decide what to grow or replace. It’s all part of the partnership Four Star has established with its grower customers, but it’s also the role, among his many, that makes Crum the happiest. As the director of growing relations and the wearer of many hats, he says he’s first and foremost a grower at heart. He has mentored countless young growers and emphasizes hands-on education and training with his fellow production teammates.

“I try to stay as close to the greenhouse and growing as I can,” he says. “I never want to lose touch and become a talking head.”

Crum started at Four Star in 1992 to produce plants for the initial season of the Proven Winners brand. Since then, though he is an employee and director at Four Star, he has guided the growth and production of the brand with his depth of knowledge and development of the many programs supporting Proven Winners.

“Dennis has a true passion for the industry,” says Tom Smith, owner of Four Star Greenhouse. “He is extremely knowledgeable, and I think he knows the Proven Winners material better than anybody in the world. He has a great feel not only for what plants will sell well and make consumers successful in the garden, but also what plants will produce well for growers.”

Crum has worked with researchers industry-wide to create production systems that solve grower problems. From the trialing and development of Four Star’s exclusive Supernova liner and the operation’s outdoor growing program, both in cooperation with Michigan State University, to working with plant nutritionists Bill Argo and Paul Fisher to develop the Proven Winners fertilizer program, he is dedicated to helping growers succeed.

The Vigor Index for combining like plants together for successful containers was Crum’s idea, and currently he’s working on a bench-run collection to make it easier for growers to produce plants with similar cultural requirements in the greenhouse. He led the creation and implementation of the in-house laboratory at Four Star and worked closely with Agdia and other pathologists to develop the testing program and sanitation protocol, both at Four Star and at Proven Winners’ two stock production farms in Costa Rica.
Within the industry, Crum stays active through research, contributing production articles to Greenhouse Grower magazine, speaking at the OFA Short Course and in greenhouse production classes at Michigan State University. A Spartan alum, he is also on the selection committee for new horticulture faculty hires.

As part of the management team at Four Star, Crum controls the budgets at both the Indian Trail Road and Sigler Road locations, which he helped to expand from seven acres to 20. Crum also oversees three offsite programs at Sportel’s Greenhouse, Henry Mast Greenhouse  and Pell Greenhouse. He also works with two stock facilities in Costa Rica on plant nutrition, production, quality and shipping issues. Crum was instrumental in streamlining shipping practices designed to deliver plants in their best possible condition and keeps the operation on track with technology. Most importantly, though, according to Smith, he keeps everyone smiling.

“I use Dennis a lot as a sounding board, both professionally and personally – he keeps me grounded,” Smith says. “He thinks through things very well and I truly appreciate his opinion. Overall, Dennis is just a lot of fun to have around. He makes work fun and he can always bring smiles to people’s faces. He likes to dish it out but he’s not afraid to take it and, especially on a management team, that’s a rare quality.”

Under Siege? Not Really, Just Go For A Walk

I have no trouble with people buying chocolates or wine instead of flowers to celebrate anniversaries, birthdays or peoples’ lives. We should all have choices. However, the other night I felt like I was entering the Republican caucus. I was minding my own business by the television set and became more than a little upset. A website called insteadofflowers.com came on the screen. It provided serene music and wholesome images of busy women doing busy things. It turns out that such busy women enjoy a small token of appreciation, but apparently their enjoyment, according to the voice-over, does not include flowers. This website delivers meals to the house, anything from beef brisket to beef bourguignon. It is a fine website with a good idea. But why pick on us? Why not use “insteadofbaloneysandwiches.com” or “insteadofgrilledcheeseandsoup.com,” “insteadofburgerdoodle.com,” or a dozen other things. When did flowers get to be the whipping boy? […]

Delegation Is Key To A Successful Greenhouse Operation

In a packed room at Cultivate’15, speaker Bernie Erven presented key steps growers need to take to improve their delegation skills, the benefits of delegating and the dangers of not learning how to delegate. This is a skill, he says, that everyone needs to learn. “For all of you who are part of a family business, you are choosing not to do things the easy way,” Erven laughed, as he presented a list of ways to know whether or not you’re an effective delegator. The owner of Erven HR Services, LLC, Erven has been working with and observing family businesses for many years. In his presentation, he said, he didn’t share anything that he hasn’t seen first-hand. You might not be a good delegator if you: Tend to be a perfectionist Work more hours than anyone else Lack time to explain clearly and concisely Are often interrupted Enjoy what you used to […]
