Free Lecture in Eugene Oregon

The Eugene Chapter of the American Rhododendron Society invite gardeners to hear a  lecture:
Truls Jensen of Wild Ginger Farm in Beavercreek, Oregon, presenting 
“Lessons From On High: Improving Your Garden Using Rock Gardening Techniques And Mountain Plants.” 
It’s FREE and open to the public
Thursday March 9th
Campbell Center, 155 High St., Eugene, Oregon
Doors open at 6:00pm
 
Mr. Jensen will discuss techniques that will enable us to better grow alpine and other mountain plants at lower elevations, and how these techniques also help us to improve our success with other perennials as well.  Many Rhododendrons and other plant species are from high mountain areas and benefit from  soil modifications and exposure for high mountain plants.  Healthy plants means happier gardeners.

Get Ready – Grow!

Seedlings in your Greenhousetwo true leaves

Start by:

  • Sanitizing your greenhouse shelves using 1 part bleach mixed with 9 parts water.
  • Clean trays and pots with this same bleach mixture.
  • Sweep floor and clean walls
  • Buy Seedling Mix – it’s not potting soil, it’s a soilless mixture for seed starting.
  • Assemble plant labels & permanent markers in your greenhouse.
  • Have your water source ready.

After you’ve sanitized  EVERYTHING!

Pre-moisten your seedling mix by pouring it into a bucket and adding water until it’s damp. Fill trays with pre-moistened seedling mix and water thoroughly.
Let trays sit a day in the greenhouse to warm up.

Start your seeds 8-12 weeks before the last frost date in your area.
In the Rouge Valley, Oregon the last frost is estimated to be May 15th.
Count backwards 8 or 12 weeks and plant seeds in your greenhouse.

Example: To plant by May 15th, then…

For 8 weeks: Plant seeds in the greenhouse by March 15th
For 12 weeks: Plant seeds in the greenhouse by February 15th

Be sure to read the seed packet instructions before planting.
These instructions tell you how deep to plant and long it takes for the seeds to germinate. And. it shows you what this seedling will look like when the seed sprouts.

Seed Heads for Winter Interest

After an exuberant display of flowers during spring and summer, the fall and winter    mofrosted-seedhead1nths leave gardeners longing for sunnier days.  A way to help overcome the winter blues is to plant winter interest in your garden.  Most gardeners know about adding texture, berries, branch color and bark, to a garden, but often flower seed heads are overlooked as a winter interest.

Leaving seed heads standing in your garden provides shelter and food for birds and insects in your yard, but seed heads also provide visual interest.  There is a quiet beauty when frost lies upon a seed head displaying its delicate wispy patterns.  Even those spider webs covering the seed heads put on a display like tiny garlands, then add frost… and those threads sparkle like crystals in a breeze. So while you’re combing through the garden catalogs during  February, look for perennials and annuals which produce interesting longstanding seed heads and distinctive structures.
