Horticulture Corner: Garden Planning and Seed Starting
County of Wetaskiwin No. 10 Horticulture Services would like to welcome a segment called Horticulture Corner — a small bi-weekly Facebook segment that highlights the joys of horticulture including garden planning, seed starting, garden harvesting, pests and disease identification, and landscape maintenance. This segment will be a way of sharing information with local gardeners. If you have a tip, question, or interesting article to share, please leave a comment below. Let’s dig in and grow together this season!
Horticulture Corner: Garden Planning and Seed Starting
After a long winter, spring is finally here. A little planning now and starting seeds indoors can help set you up for a productive growing season.
Here are a few helpful tips for planning your garden this year:
- Keep a small garden journal or logbook to help you remember what you planted each year.
- It is important to have a 3 to 4-year crop rotation in your garden plots to manage soil fertility and limit soil borne diseases.
- Grow nitrogen fixating plants such as beans and peas after heavy feeders such as tomatoes, cucumbers, and peppers.
Starting seeds indoors gives your plants a head start on the growing season, especially crops that take longer to mature. Here are a few tips to get started this season:
- Follow the instructions on the seed packet; this will give you an indication when to start seeds indoors before the last frost date.
- If re-using seed trays from previous seasons, make sure to disinfect pots and trays to avoid soil borne diseases from previous plantings.
- Consider using a heat mat, as bottom heat will increase the germination rate and promote healthier roots. It can also help prevent damping off --- a disease that can cause weak seedlings and seedling losses. Damping-off is caused by pathogens on the surface of the potting mix or soil.
- Use grow lights for 12 to 16 hours per day, which is ideal for seedlings. Avoid leaving grow lights on continuously, as seedlings require periods of darkness for proper development.
- Keep the grow lights 2-3 inches above the seedlings, as lack of lighting will cause stem elongation causing seedlings to become leggy.
- Do not forget to harden off seedlings 1-2 weeks before transplanting outdoors to reduce transplant shock.
