Gathering Spot making progress towards late Fall opening!

The new Gathering Spot is slowly but surely "gathering" speed towards our projected opening date of December, 2014.  Recently, the classes of "Turf Management" and "Plant and Horticultural Science" pitched in their efforts in building the seating walls, adding soil, installing irrigation, and laying sod.  (see picture below). 

The sod is a drought-tolerant and water saving hybrid Bermuda grass called Tifway.  This grass was chosen after seeing how various events held on the lawns affect the grass and for its lower water needs.  Hybrid Bermudas can tolerate traffic, blankets and tarps laid on them during events, and recover quickly if any damage occurs.

Our next phase of construction will include the layout and installation of permeable pavers for the walks and patios.  These pavers allow water to penetrate through into the soil below and reduce and eliminate most runoff.  After pavers are installed, an outdoor BBQ, serving counter, and a pizza oven are planned.  These items will be installed by the fall Landscape Construction class.

Special thanks go out to Eddie Munguia (horticulture field site manager) and Alan Canedo (student worker) for their hard work in getting these areas ready for the various stages of construction.

New Design and Installation in Progress at the Gathering Spot

The South Bay Botanic Garden at Southwestern College is currently undergoing a re-design of the Gathering Spot.  The Gathering Spot has been a nice quiet landscaped area where campus activities, small graduations, and other social events have occurred.  This area was dedicated to Dr. Bill Nelson, past owner of Pacific Tree Farms in Bonita, who frequently donated unusual specimen trees to the botanic garden.

 

The renovated area will contain a larger lawn area for seating a higher number of people.  It will also have a newly constructed barbecue and serving area along with a larger patio  for socializing.  What makes this area even more special is the way in which it involves students taking classes in both the Landscape and Nursery Technology and the Landscape Architecture programs in its design and construction.

The initial design was a result of students in the LA 104 - Landscape Graphics and Planting Design class all creating new conceptual ideas for this project.  This occurred last spring and the winning design, drawn by student Onie Hadloc, was selected after being evaluated by both students and LNT faculty and staff.  Now that the design has been chosen, the installation process is now in process with the Fall 2013 LNT 125-127 - Landscape Construction class.  The first phase involves the creation of seating walls, retaining walls, and permeable pavers for the walks and patios.  Later construction will involve the Sprinkler Installation class in installing the latest in water-saving irrigation systems and controllers.  Then, the Spring 2014 LNT 132 - Turf Management class will install the new lawns using a drought tolerant variety of either hybrid bermuda grass or paspalum grass.  Here is a photo of the first phase of construction work:

Finally, the new site has been adopted by a local supplier of pavers, wall systems, and outdoor kitchen hardscape blocks.  Belgard Hardscapes has graciously offered to supply all the hardscape units for the new project and also offered to bring in experienced landscape contractors to demonstrate to students the proper installation methods.  The South Bay Botanic Garden and Southwestern College thank this fine company and Seth Seaton, their representative on this job. 

This entire project is being overseen by LNT adjunct instructor Michael Watts and installed by his Landscape Construction class.  Look for possible completion of this project by the end of the Spring 2014 semester. 

Formal and Rose Garden gets an Irrigation Update - Water Savings Ahead!

The Formal Garden, which also houses our rose collection, recently received an irrigation improvement that will save 1,000's of gallons of water each year.  This garden has always been irrigated with pop-up spray heads.   These heads did an adequate job of watering but applied water at a rapid rate of about 1.5 inches per hour.  With our tight clay soils, it made it almost impossible to achieve proper water penetration deeply to the roots.  The solution: install a drip system.

The new drip system consists of two types of drip distribution methods.  For the boxwood hedges that define the space, Netafim brown tubing was used.  This tubing has preinstalled holes in the tubing, each located 12" apart, that apply a little less than one gallon per hour each.  By running this system about one hour, each plant will get around 1 gallon of water that is applied so slowly that water can penetrate very deeply.   This results in a deeper root system and plants that will not need to be watered as often.

The second distribution system uses micro-spray sprinklers for the roses and the planned irises.  These sprinklers are supplied with drip tubing and operate at low pressures and low distribution rates and will allow us to water just beneath the foliage of the roses and not require that we water the entire square footage of the rose bed.  In addition, since roses do not like overhead spray on their foliage, this system will result in less diseases such as powdery mildew.

The system was installed with the help of horticulture field site manager Eddie Munguia, new student worker Alan Canedo, and volunteer help from Eddie Palmerin.  Also, students from the class of LNT 92 - Sprinkler System Maintenance helped to run many of the new drip irrigation tubing lines and installed many of the micro-spray heads.

Since some of the roses were not performing well, look for new additions this late winter as the bare root rose season appears.
