Dew is the water that forms on plants and other surfaces when warm air cools down at night. It’s natural, but too much dew can cause issues for your plants.

The Good Side of Dew

  • Provides some water for plants
  • Helps cool plants on hot days
  • Can look pretty in the morning sun

The Bad Side of Dew

  • Can lead to fungal growth
  • May cause leaf rot
  • Can attract harmful insects

Understanding Your Garden’s Dew Patterns

Before you can protect your plants, you need to know how dew affects your specific garden.

Factors That Influence Dew Formation

  1. Climate: Some areas are more prone to heavy dew
  2. Season: Dew is often heavier in spring and fall
  3. Plant location: Low spots in your yard may collect more dew
  4. Plant type: Some plants are more sensitive to moisture

How to Check for Dew Problems

  • Look at your plants early in the morning
  • Feel the leaves for moisture
  • Check for any signs of mold or rot
  • Notice if some areas of your garden are wetter than others

Choosing Dew-Resistant Plants

One way to avoid dew problems is to choose plants that can handle moisture well.

Plants That Do Well in Damp Conditions

Improving Air Flow in Your Garden

Good air circulation helps dry dew faster and prevents moisture-related problems.

Tips for Better Air Flow

  1. Space plants properly: Don’t crowd them together
  2. Prune regularly: Remove dead or crowded branches
  3. Use supports: Trellises and stakes can lift plants off the ground
  4. Create paths: Leave room between plant groups for air to move

Smart Watering Practices

How you water your plants can affect dew buildup.

Use these tips to water wisely:

Best Times to Water

  • Early morning: Gives plants time to dry before night
  • Late afternoon: Avoid watering in the evening, which can increase dew

Watering Methods to Reduce Moisture

  1. Water at the base of plants, not on leaves
  2. Use drip irrigation or soaker hoses
  3. Avoid overhead sprinklers when possible

Mulching for Moisture Control

Mulch can help manage moisture levels in your garden.

Benefits of Mulching

  • Keeps soil moisture even
  • Reduces water splashing on leaves
  • Can prevent some fungal growth

Best Mulches for Dew Control

  1. Wood chips
  2. Straw
  3. Gravel or pebbles
  4. Pine needles

How to Apply Mulch

  1. Clear the area around plants
  2. Spread a 2-3 inch layer of mulch
  3. Keep mulch away from plant stems
  4. Refresh mulch as needed

Using Covers and Shelters

Sometimes, physical barriers can help protect plants from dew.

Types of Plant Covers

  1. Row covers: Light fabric that lets air and light through
  2. Cold frames: Mini greenhouses for small plants
  3. Umbrellas: Can shield individual plants
  4. Hoop houses: Larger structures for protecting many plants

When to Use Covers

  • On nights when heavy dew is expected
  • During rainy periods
  • In early spring or late fall when nights are cool

Soil Management for Dew Control

Healthy soil helps plants deal with moisture better.

Improving Soil Drainage

  1. Add organic matter like compost
  2. Use raised beds in wet areas
  3. Create slopes or channels to direct water away

Soil Amendments for Moisture Control

  • Sand: Helps improve drainage in clay soils
  • Perlite: Increases air pockets in soil
  • Vermiculite: Helps retain some moisture while improving drainage

  2. Improve air circulation around the plant
  3. Use fungicides if necessary (follow label instructions)
  4. Adjust watering practices

Seasonal Dew Management

Different seasons bring different dew challenges.

Here’s what to do throughout the year:

Spring

  • Start good air circulation practices early
  • Use row covers on cool nights
