Vermicast Tea – Hot Summer Months

Using vermicast tea (aka worm tea) in the summertime is a powerful way to boost plant health and soil biology — without burning plants, even in hot weather. Here’s how and when to apply it effectively:

WHEN to Use It

• Best Times of Day:
  • Early morning or late afternoon/early evening
  • Avoid applying during midday heat to prevent microbial die-off and leaf scorch.
  • Beneficial microbes thrive in cooler, shaded conditions.
• Frequency:
  • General garden boost: Every 2–4 weeks
  • Stressed or heavy-feeding plants (e.g. tomatoes, cucumbers, melons): Weekly
  • Seedlings/transplants: At planting and again 1–2 weeks later

HOW to Apply It

• As a Soil Drench (most effective)
  • Pour tea directly around the base of plants to soak into the root zone.
  • Encourages root growth and boosts microbial activity in the soil.
• As a Foliar Spray (bonus use)
  • Use a fine spray to mist the leaves (top and underside).
  • Helps protect against fungal and bacterial pathogens.
  • Apply when temps are under 85°F to avoid leaf damage and preserve microbes.
