Dan Schantz Greenhouse

Miles of Mums. Loads of Lilies. A plethora of Pansies.







Twenty-five acres of greenhouse space stretched in front of us on a cold March morning in Zionsville, PA. I visited one of four greenhouses in the Lehigh Valley owned by Dan Schantz.



This is the birthplace of ‘Dan’s Favorite’ tomato I wrote about last summer.

The computerized and automated process is a marvel of modern technology. Temperature is monitored by computer system. An alarm sounds if the temperature gets too high or too low. Most of the watering is programmed using recycled water. Hanging baskets move slowly overhead to the watering nozzle.
But much is done by hand. The greenhouses employ hundreds of workers.

Thousands of lilies are checked - one by one. The lily buds are measured against a template. If the bud gets too large the plant is moved to a cooler location to slow the process. All the lilies must bloom simultaneously for Easter.


Each tiny tomato seed is placed by hand in a grid of starting mix.
Tomatoes flourish in various stages of growth, from newly planted seed trays to small plants in neat rows. It is all timed to be ready for shipment in April or May.

The plants from Dan’s wholesale operation are shipped to big box stores and garden centers up and down the east coast. Retail stores are located on Lehigh Street in Allentown and W. Union Boulevard in Bethlehem.

It runs like a well-oiled machine and I saw how Dan’s favorite tomato got its start.

Longwood - Service Area


http://www.longwoodgardens.org/

As part of our Longwood Gardens tour, we visited the service area directly behind the Main Conservatory. (Yes, we went beyond the sign.) 30,000 square feet of state-of-the-art production greenhouses produce plants used in the exquisite displays.

Huge fans keep the greenhouses cool in summer. Cool air is pulled in from the wooded area behind the greenhouses through the tan, corrugated screen shown here behind the coleus. Miles of pipes, automatic temperature and water controls, gizmos and gadgets make it a gardener’s dream. According to Longwood’s publication, “Each greenhouse is equipped with its own computerized system that automatically controls temperature, bench and perimeter heat, snow melters, and devices for cooling and shading.”

“In the mid 1950s, Longwood began a breeding program to develop new cultivars. Today, outstanding cultivars are continually being selected and regularly introduced.” More than 100 cultvars have been introduced by Longwood Gardens Research Staff – everything from Acer platanoides ‘Stand Fast’ to Wisteria frutescens ‘Longwood Purple’.

The huge greenhouses were almost pristine inside. Believe me, there was no soil or plant litter on the floor.

The greenhouses also serve as a holding area for replacement plants for the display gardens. Tables were filled with red, pink, salmon poinsettias, bright red and white cyclamen, dusty miller.

As we walked through, an intern from Ohio expertly transplanted snapdragon seedlings Antirrhinum majus ‘Appleblossom’. (Picture in bloom http://davesgarden.com/community/forums/fp.php?pid=3485053 ) They should make a beautiful display.

A long row of Velvet Groundsel - Roldana petasitis lined one of the service halls. It is considered a “pest plant” in New Zealand. (Here is a picture in bloom http://shadoadmin.arc.govt.nz/plants/plantdetails.cfm?plantcode=senpetmin.arc.govt.nz/plants/plantdetails.cfm?plantcode=senpet )

It would be fun to return to Longwood in another season to look for the plants we saw in the greenhouses.
