New YouTube series

This fall, we're unveiling a new video series about gardening tips and our favorite plants in the garden! Check out the first video:

Summer at the garden

Summer is a busy time for us here at the garden! We are pruning, watering, hosting tours, and collecting data. Here are some updates!

  • This summer, we have 370 new varieties of plants on trial, ranging from petunias, calibrachoas, hibiscus, gomphrena, caladiums, and many others.
  • We have 4 new student workers here at the garden during the summer. Our student workers fertilize, prune, water, and everything in-between to keep the garden in tip-top shape. You can read more about them here.
  • We installed several cooling pads in our greenhouse last fall to keep our greenhouse nice and cool this summer.
  • We planted a Georgia "G" in a bed next to the greenhouse and visible from the windows of the pharmacy school. We used ornamental peppers, vincas, and lots of string to create a crisp design. Pictures will come as the vincas fill in!

How to read trial results

When viewing the annual results, these are some helpful hints to keep in mind so that you can understand how to interpret the chart and each plant's score:

1. We plant our garden in mid-to-late April and start taking data the first week of June. So plants that start out at a 4 or 5 have been growing for around a month have been getting regular fertilizer and water. When we do plant, we only plant 'finished' pots.  Anything that has not developed well in the pot in the greenhouse are planted later.

2. Generally speaking, any plant with a score of 3 - 3.5 would be considered a desirable plant for any garden.  Plants that are score at consistant 3s means that the plant looks healthy but is not excelling in new growth or flower production. 

3. Plants scoring between 3.5 and 4.5 are both flowering well and producing consistand new growth. This is the largest group in the garden.

4. Plants scoring between 4.5 and 5 are the plants that are truly standing out above the rest of the flock.  These plants are both flowering profusely and/or maintaining a consistant desirable shape in the garden. 

5.  Watch for trends where some plants performed well early season and have dropped off as the summer has progressed. Likewise, some plants have had a slow start and are coming into their season the later in the summer we go. Typically, better scoring plants are maintaining slight dips and rises that correlate with their bloom cycle, i.e. in bloom: better score, out of bloom: lesser score.

Garden Trials
The performance ratings are based
on number of flowers, leaf color,
uniformity of habit and flower,
resistance to insects
and diseases and
overall appearance.
