Winter at the Garden

During the Winter much of nature is dormant, but it is still a busy and very exciting time here at the Trial Gardens - here are some updates!

- New trials for 2019 are arriving! We are sowing seed and will be receiving plugs in March.

- Plants for our annual Plantapalooza plant sale are being grown and cared for. This sale helps fund 100% of the pay for our student-workers here at the Trial Gardens!

- Preparations in our garden have started! We are laying pine straw, cleaning out all pots, and removing last years debris. All of this is done before we further prepare to plant any of our trials later in the Spring!

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.
