Chillin' for a Peach Fillin'

My first peach tree is flowering.  ‘Flordaking’—and, yes, there is not an i missing. The name gave me pause the first time, too—arrived last fall in a six-foot-long box. Upon opening said package, to my surprise a six-foot-tall Prunus persica was inside.  I guess that’s what happens when you buy a five-gallon tree.

I sited it in our edible patch.  I had initially set aside this approximately 100 × 100 ft fenced area to be an orchard, but after mental iterations, it became clear after some damage from deer, boar, rabbits, and armadillos that the area would be better suited for more annual production since they were obliterated elsewhere.  I slated the back third edge-habitat area for fruit trees, and the rest of the front was for cut flowers and veggies.  

While I’m more of a nectarine person myself, Karen likes them; therefore, in the orchard a peach went.  The reason I chose ‘Flordaking’ is because of its low chill requirement.  In horticulture we talk about chilling hours as a measure for how much cold a plant must receive before it flowers, and while there are different approaches to calculate that number, let’s say that we count the hours under 45F.  

I teach students that a tree’s chill requirement is an alarm clock. It is a wonderful adaptation that some temperate trees have to the extreme stress of being exposed to cold temperatures in the winter.  Just like some people need 6 hours of rest and others need 8 (…or 10), some peaches need a few hundred hours down south while others further north require 1000 hours.  

Chilling causes sugar levels in the trees to increase and hormone levels to change.  The tree must be exposed to a certain amount of chilling to be able to flower.  If not enough chilling is perceived, then the plant can’t flower because enough metabolic changes haven’t occurred yet.  The alarm clock hasn’t gone off and the tree can’t wake up.  In fact, planting a high chill requirement tree in the south where we have warm winters every so often may result in the plant being extremely delayed in growth.  

‘Flordaking’ is estimated to need about 400 hours of cold.  Released by the University of Florida in 1978, it’s touted to be one of the best varieties for us to plant in zone 8.

The appearance of petals in recent weeks indicated that the snooze wasn’t pushed. Instead, the tree is rising and shining. It is pure delight to watch the petals unfurl.  The other afternoon I stood and watched a bee work the sparse flowers on the little tree in the waning light.  It wasn’t very skittish and allowed me to get close and observe it swimming in the stamens to get the nectar at the center. While peaches are self-fertile and one tree will produce fruit, I’m going to add another one or two to the patch for some diversity.  

This list has been helpful picking some low chill varieties for our garden.  Maybe it’ll help you, too.  

Sprout Germinates

I’ve been at Stephen F. Austin State University (SFA) for a year and a half now, and in the haze of starting a new job (and, a wonderful haze it has been!), I haven’t had a chance to record the progression of thinking I’ve had on garden projects at SFA.  Thus, I wanted to start doing a series of blog posts to bring myself (and you) up to date on my activities.

I was so thrilled when I got the job at SFA.  Teaching about plants and horticulture has been my career goal since I was at least a freshman in undergrad.  The biggest challenge I would face at SFA was student enrollment.  The number of horticulture students were at a lull (much like they are across the country), and my colleagues were trying to discover a way to increase enrollment.   They shared with me that a fresh face would help, but I knew that we had to do more that just be present.  We had to visibly show the students that we were relevant and that we cared about their lives and their futures.

While I was pondering how to engage with more students, I was also trying to see where I fit.  I’ve had the herbaceous plant craze for several years, and I knew that there was an opportunity to beef up the perennial collections.  On top of that, SFA already has a large woody plant collection, and several of my colleagues across the nation are doing great work with woody plant breeding and evaluation. So, in the spirit of zigging instead of zagging, I starting laying the groundwork for working with herbaceous plants.

That was also the time when I realized there was a way we could weave edibles into the mix.  In conversations with Dawn Stover, the research associate at SFA Gardens, I discovered there was an edible garden on campus, the SFA Sustainable Education Community Garden.  This garden's original focus was to grow produce and then donate it to the community, but eventually, the garden produced so much food that some of it was being sold at a small farmer’s market behind our ag building on the SFA campus.

I quickly realized that this garden was it.  This garden is how we could begin to bridge the gap to help connect horticulture with students.  If we couldn’t at least engage their hearts, we could bridge a connection with their stomachs.

And, of course, I don’t have to belabor how big edibles are right now with young people.

I offered to take over the garden and revamp it since SFA Gardens had many other projects on their plate.  Right off the bat, I knew that the SFA Sustainable Education Community Garden needed a mission (and a shorter name).  But, I hate the word mission because so many organizations have missions but never really follow these framed statements on the walls.  We would have a story as Ty Montague describes, and our day-to-day actions would tell our story, a story I hope would attract both students and people from the community.  

Plants were an obvious choice to be part of our story.  But, which plants?  I chose to focus on edibles and 21st century relevant herbaceous plants (plants for zone 8, urban areas, designed plant communities, etc.).  I felt that both areas would help us to be relevant to students.  We could grow the plants, evaluate them, use them in classes, and report our evaluations to the public.

I wanted our story with the garden to also focus on students.  One thing that I heard over and over at SFA is that they wanted students to have more hands-on learning, and I saw the garden as an opportunity for tangible growth for students.  I wanted the garden to be something that students enjoyed and be designed to get students talking and engaged.  We as a people are ultimately social organisms, and one of the best ways to engage people with horticulture is to get them excited and share ideas with their friends.

The community was also a central focus.  Dawn told me that one of her favorite parts of the farmer’s market was that we had the opportunity to connect horticulture with a different audience on campus.  And, I saw that we could do more events and tours to help educate, inspire, and connect with people in the community even more.

Plants.  Students.  Community.  And with that trinity, we rebranded the garden as Sprout—a garden for tangible growth for plants, students, and the community.  Not too shabby if I do say so myself.  I even doodled a new logo for the garden.

We also have one more part of our story woven into all three of those parts.  Fun.  We want to teach people that gardening is fun and enjoyable and adds to the quality of life.  And, we try to embellish everything that we do in the garden with that philosophy.

I hope that my brain dump will help guide you if you are faced with a similar situation in your career.  Thanks for reading about the start of Sprout.  Soon, I will do a post about our first year successes and failures.  Until next time, keep growing!
