Topic overview from our workshop
How to Successfully Grow Your Garden from Seed!
Know your last and first frost dates – most important thing to know, as all key planting decisions and dates are based on this important knowledge.
Link to your frost dates by ZIP code – bit.ly/FirstLastFrostDates
Last frost date is 50% chance of Spring 32°F frost, first frost date is 50% chance of Fall 32°F frost.
Tips for stronger seedlings –
- Start seeds a week earlier
- Transplant a week later
- Provide weather protection
Choose appropriate varieties for your climate and length of growing season – what are you going to do with what you grow, what do you like to eat? Then, choose varieties for the number of days in your climate
3 germination factors –
- Moisture – soil should be initially very damp, then after seed sprouts barely moist
- Temperature – Initially very warm to sprout, then drop to around 70°F
- Light – Initially not needed, then once seedlings have leaves – 16 – 18 hours/day
Changing conditions to suit seed sprouting and seedling growth will avoid problems – decrease moisture and temperature will greatly decrease chance of mold related health issues
Early and late frost protection can greatly extend your growing season
- Quick, small hoop house or row tunnel with plastic cover
- Lightweight plastic on top of plants
- Bubble wrap on soil to maintain root temperature
Tips for direct sowing of seed –
- Depth of seed planting –usually no more than 2 – 3 times seed diameter
- Proper soil temperature – warmer gives faster, stronger germination
- Seed orientation – point that was attached to the fruit or plant grows the root
