As winter begins to fade and the days grow longer, March is a crucial month for gardeners who have started their seeds using the winter sowing method. Proper care during this time ensures healthy growth and a successful gardening season.
Understanding Winter Sown Seeds
Winter sowing involves planting seeds outdoors in containers during the winter months, allowing them to naturally stratify and germinate when conditions are right. This method is especially popular for hardy plants such as perennials, vegetables, and flowers.
Key Tasks for March
1. Monitor Weather Conditions
Keep an eye on the weather forecast. While winter sowing is designed to withstand cold temperatures, sudden frosts can damage young seedlings. Be prepared to protect your containers if a late cold snap is expected.
2. Check Seedlings Regularly
Inspect your containers frequently for signs of germination. Seedlings should begin emerging as temperatures rise. Remove any weeds or unwanted plants that may compete with your seedlings.
3. Protect Young Plants
If frost is forecasted, cover your containers with frost cloths, old blankets, or plastic sheeting. Ensure covers are secure but allow for air circulation to prevent mold and damping-off disease.
Maintaining Proper Conditions
1. Watering
Keep the soil consistently moist but not waterlogged. As temperatures increase, seedlings may need more frequent watering. Use a gentle spray to avoid damaging delicate shoots.
2. Ventilation
Ensure good air circulation around your containers to prevent fungal diseases. Open covers during the warmest part of the day if using protective coverings.
Preparing for Transplanting
As seedlings grow stronger, begin to harden them off by gradually exposing them to outdoor conditions. This process helps prevent transplant shock when moving plants to your garden.
Hardening Off Tips
- Start by placing seedlings outside in a sheltered spot for a few hours each day.
- Gradually increase the duration and exposure to direct sunlight over a week or two.
- Water seedlings well before transplanting to reduce stress.
By following these steps in March, you set the stage for a vibrant and healthy garden. Patience and attentive care will reward you with strong plants ready to flourish as the season progresses.
