Three weeks ago, many turfgrasses began greening up as surface soil temperatures warmed into the 50s °F during the day. Currently, surface soil temperatures are reaching into the 60s °F during the day, which stimulates vertical leaf growth especially after a rain. Any early spring N fertilization will also encourage vertical leaf growth. Accordingly, mowing equipment […]
Roughstalk bluegrass
Roughstalk bluegrass (Poa trivialis) is a cool-season perennial grass often considered a weed. Light green in color it is most obvious in the early spring when it grows more rapidly than other turfgrasses. As temperatures rise in the summer its growth will slow and it often goes semi-dormant until cooler temperatures and rainfall return in […]
Mechanization of Pruning in NJ Container Nurseries
In the 2017 survey of labor and mechanization of New Jersey’s nursery industry, pruning was ranked, the third most important operation, that needs mechanization the most (41 responses). In spite of obvious benefits such as efficiency, quality, and consistency, lack of practical information about the mechanized pruning is delaying the rapid adoption by container nursery growers. This article summarizes inputs from Chris Ruske of (Cumberland Nursery), Donald Blew (Centerton Nursery) and Ed Overdevest (Overdevest Nurseries) on pruning mechanization, shared during the panel discussion at Clayton in Gloucester County in January 2018.

Weed Control in Spring Seedings
The recent warm weather means its time to started on lawn and landscape projects. You may have plans to seed bare spots in the lawn that you didn’t get to in the autumn. These bare spots may be the result of fungal diseases, which were aplenty due to heavy rainfall in 2018. Summer annual weeds […]

Spacing Robots – Experiences of the Container Nursery
Spacing is one of the most labor intensive and least desirable jobs on the nursery. Continuous moving, bending and twisting with filled containers is also the common cause of workers’ injuries. Using robots for spacing and moving, can address these challenges, however has its own challenges. During a panel discussion on the Nursery Mechanization, held at Clayton in Gloucester County on Jan 16, Donald Blew of Centerton Nursery, shared their experiences in using robots.
- Efficient Utilization of the Space: The big reason for Blews was not because they could not find the labor or because it was cheaper, but the fact that robots are good at spacing pots in hexagonal pattern and saving spaces and saves money on that. “If you draw a square and put your four pots in it, you have that extra space in the middle that is not being used. If you put them in a hexagonal pattern, you can use a little bit more of that free area that you have”. Robots can do that with precision. It saved them right around 10 greenhouses last year! At eighteen hundred square feet a piece, it is quite a bit of area gained. Previously, they could fit 24,000 three-gallon hydrangea in one greenhouse. Now, with spacing robots can add 6,000 more, with the same center-to-center distance between pots. So, for every three and a third house they saved at least one house. Other thing is that it lets you know exactly how many plants are going into the greenhouse which gives an ability to refill greenhouse after, say you shipped half of the greenhouse. There are calculations and online spreadsheets that make it easy.
- How does it works? No, they don’t work on GPS. They have very simple lasers and sensors. It is actually taking the number of wheel count, so it knows how far it is going by how many revolutions making. You apply a boundary marker, along one edge/side of the bed, and then put at least one container down-faced to establish the reference point or boundaries. Then enter certain parameters such as specifying either the square or hexagonal pattern, spacing between and within the rows, on robot’s human interface. “Mark the center with D.O.T. tape and now you can use two Robots”, said the owner of four such robots.
- Challenges: Biggest challenge is that it needs a skilled labor to operate and maintain, including charging batteries, every four to five hours. If you have four of them, you may need one person dedicated to just do that. According to Donald Blew ‘there are days when it can take a full day just to troubleshoot or repair the robots’. Machine is expensive, costs around 35,000 per piece. On an average people are getting five to ten years out of them. By the time you have paid off, it’s time to get a new one. However you can lease them through Farm Credit.
- Do your math before buying. Ask yourself how many man-hours you spend, doing the operation that robots could replace. Then do the math as far as payroll. If number make sense and handle the challenges then by all means, buy the Robot.
