Transition Palo Alto Garden Notes for March

 

I’m so grateful for the bit of rain we’ve had, aren’t you?  I used to race to get my tomatoes and other warm-weather crops into the ground, hoping to get a “head start.”  But after many disappointments, I’ve learned that those heat-lovers should not be planted until the soil temperature is consistently warm.  And with our recent cold-night temperatures, that may not be until May!

 

1. Cool season annuals can withstand light frosts:  carrots, beets, radishes, chard and other greens, and nasturtiums can be directly seeded now.

2. Warm season vegetables have no frost tolerance: beans, cucumbers, eggplants, melons, peppers, squash and tomatoes. You can start seeds inside, or purchase at Master Gardeners Spring Garden Market, March 31 http://mastergardeners.org/spring-garden-market or at a nursery.

Starting Seeds at Home – some tips

  1. Use wide flat containers to avoid overcrowding. You can use recycled containers like yogurt tubs with holes poked in the bottom for drainage. You can sanitize containers by soaking in a 10% bleach solution for 15 minutes and air drying.
  2. Fill containers with fresh potting soil, making the surface smooth and level.
  3. Place seeds on the soil, sprinkle gently with soil or a soil-less seed starting mix evenly over the top. The seed must be in firm contact with the moist soil to begin germination. Use a pestle or the bottom of a glass to gently tamp down the surface.
  4. Provide air flow and drainage to prevent disease. If you cover the trays with plastic wrap to keep the moisture level constant, you should still check them daily. As soon as the seeds germinate, remove the plastic.
  5. Keep the seeds warm to encourage germination and turn daily to keep stems strong.
  6. When plants emerge, thin to no more than 2 plants per cell if using 6-packs.
  7. Before seedlings can be planted outdoors, they must be hardened off. You can do this over a three-day period by placing them in direct sunlight the morning of the first day, then increasing the time outside by a few hours each day until they are vigorous enough to be transplanted.

Citrus leaves yellow this time of year
If your citrus leaves are yellowing, you might be convinced something terrible is happening to your prized Navel orange or Meyer lemon. Don’t panic–yet. Citrus trees put much of their energy and resources into fruit production this time of year and yellowing of the leaves is common.

  • ·Fertilizing citrus. A nitrogen fertilizer (which will help green up the leaves) can be applied prior to bloom and again in May or June.
  • ·Pests and disorders of Citrus. Consult this UC Davis website if something is obviously wrong with your tree.
  • ·Frost protection (PDF). Make sure the soil is well-watered and protect your citrus from frost.
  • ·General fruit tree advice. Consult the UC Backyard Orchard references pages for advice and care of all backyard fruit trees.
