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.

Gardening Tips

February:  Preparing to plant in the Rogue Valley

wet-soil

Soil: too wet

Grab a handful of your soil, if you can form it into a ball, the soil is too wet for planting and chances are the seeds will rot in the ground. Plant only when the soil crumbles and falls apart after you squeeze it.

Soil pH: Use a pH soil test kit to test your soil. Kits are available at most garden centers. If you soil is too alkaline, above ph7, then incorporate lime into your soil. Lime is best added in the fall, but you can still do this in early spring. Apply Lime early in February, then a week later add in fertilizer.  Both materials should be incorporated into the soil 6 to 8 inches. Wait at least a week after applying fertilizer before planting seeds.

You can direct sow the following seeds in your garden mid-to-late February, if the soil is no too wet and temperatures are staying above 20 degrees!
Peas, non-enation resistant varieties
Early varieties radish
Spring Spinach
Fave beans
Mustard
Spanish Onions (the most common onion is the USA),

Sow the seeds listed below, indoors or in a greenhouse in February for transplanting into the garden in 6-8 weeks:
Lettuce
Cauliflower
Broccoli
Bok Choy
Pac Choi
Mustard
Cabbage
Kale
Leeks
