How to Grow Zinnia Cut Flowers Using Weed Barrier

Hey there!

Today I’m excited to share how to grow Zinnia cut flowers using weed barrier! After years of planting a few flowers here and there last year I decided to create a 250 foot cut flower bed along one of our fence lines. And with minimal effort it turned out better than I imagined!

Growing zinnia cut flowers can be a rewarding experience for both novice and experienced gardeners. Zinnias are known for their vibrant colors, long blooming periods, and ease of growth. One effective method to cultivate zinnias while keeping weeds at bay is using a weed barrier with holes burned into it. This technique not only reduces weeding time but also ensures healthy, robust plants. In this guide, I’ll walk you through the process of growing zinnia cut flowers using this innovative method.

Why Choose Zinnias?

Zinnias are a favorite among gardeners for several reasons:

  1. Vibrant Colors: Available in a wide array of colors, zinnias can brighten up any garden.
  2. Long Blooming Season: They bloom from late spring until the first frost.
  3. Easy to Grow: Zinnias are low-maintenance and thrive in various soil types.
  4. Attractive to Pollinators: They attract bees, butterflies, and other beneficial insects.

Benefits of Using Weed Barrier

After deciding to plant a cut flower bed along one of our pasture fence lines we opted for the weed barrier method.

Using a weed barrier with holes burned into it offers several advantages:

  1. Weed Control: Significantly reduces weed growth, which can compete with zinnias for nutrients and water.
  2. Moisture Retention: Helps retain soil moisture by reducing evaporation.
  3. Soil Temperature Regulation: Maintains a consistent soil temperature, promoting healthy root growth.
  4. Cleanliness: Keeps flowers and leaves clean by preventing soil splashes during watering or rain.

Step-by-Step Guide

Tractor Supply1. Prepare Your Garden Bed

  • Choose a sunny location, as zinnias need full sun (at least 6-8 hours of direct sunlight per day).
  • Remove any existing weeds or debris from the garden bed.
  • Loosen the soil with a garden fork or tiller and amend it with compost to enhance fertility and drainage.

2. Lay Down the Weed Barrier

  • Roll out the weed barrier fabric over the prepared garden bed.
  • Cut the fabric to fit the dimensions of your garden bed, ensuring it lies flat without wrinkles.

3. Burn Holes into the Weed Barrier

  • Measure and mark the locations where you want to plant your zinnias. Space the holes about 12-18 inches apart to allow for proper air circulation and growth.
  • Using a propane torch or handheld torch, carefully burn holes at the marked spots. Burning the holes helps seal the edges, preventing fraying.
  • Be cautious when using the torch and follow all safety guidelines to avoid accidents.

4. Planting Zinnia Seeds or Seedlings

  • For seeds: Plant 2-3 zinnia seeds in each hole, covering them lightly with soil. Water gently.
  • For seedlings: Dig a small hole at each burned spot, place the seedling in the hole, and firm the soil around it. Water thoroughly.

5. Mulching (Optional)

  • Apply a layer of mulch around the plants but avoid covering the holes. Mulch helps retain moisture and further suppresses weeds. We haven’t added mulch yet since we have some longer term plans for this bed.

6. Watering and Maintenance

  • Water the zinnias regularly, especially in the beginning, keeping the soil consistently moist but not waterlogged. Avoid overhead watering to reduce the risk of fungal diseases. I usually water daily if it doesn’t rain for the first 2-3 weeks.
  • I do weed the holes when necessary until the flowers take over.
  • Deadhead spent flowers to encourage continuous blooming.
  • Monitor for pests and diseases, and take appropriate action if needed.

Tips for Success

  • Choose the Right Varieties: Opt for zinnia varieties known for their suitability as cut flowers, such as ‘Benary’s Giant’ or ‘Oklahoma’.
  • Fertilization: Feed your zinnias with a balanced fertilizer every 4-6 weeks to promote vigorous growth and flowering.
  • Harvesting: Cut zinnia flowers early in the morning when they are well-hydrated. Use clean, sharp scissors or garden shears to make a clean cut just above a set of leaves.
