All About Vertical Gardening: Protecting Vertical Gardens from Disease

Since vertical gardens grow up rather than along the ground, the risk of disease is significantly reduced with limited contact with the soil.

However, that doesn’t mean your plants will be disease free in a vertical garden.

As with any type of gardening, the first step to avoiding disease is the quality of the soil. If this is the first season for your vertical garden, make sure you start with soil from an area from which all weeds have been removed and the soil has been vigorously turned and mixed with clean compost. For an existing vertical garden, you’ll still want to weed and augment your soil with compost, but also make sure you have rotated your crops from their planting locations the previous year.

Plants such as squash, cucumber and peas are highly susceptible to disease when planted in the same spot as the previous year.

Two common diseases that affect vertical gardens

  • Anthracnose: This fungus most often affects cucumbers, watermelons and muskmelons, and is most prevalent during warm, humid conditions. To protect your plants, rotate crops annually, leave enough space between plants to let leaves dry out as quickly as possible and promptly remove/destroy affected leaves and fruit to prevent spreading. To help prevent or eliminate anthracnose, use Safer®Brand Garden Fungicide or Safer®Brand 3-in-1 Garden Spray, which acts as a fungicide, insecticide and miticide. Both are OMRI Listed® and compliant for use in organic gardening.
  • Bacterial wilt: This disease is indicated by vines that wilt in the day but recover at night. Try to purchase disease resistant species and watch for cucumber beetles, which spread the disease.

ALL ABOUT SQUASH: Squash Bugs and Diseases

As with most vegetable plants, squash bugs and diseases can quickly eliminate a garden crop without regret. Keep eyes peeled for damage to leaves, flowers, or fruits to eliminate a garden takeover before it is too late!

Aphids – curled or yellowed leaves indicate an aphid infestation. Use a pyrethrin-based spray like Safer® Brand Tomato and Vegetable Insect Killer to kill insects on contact without harming plants.

Cucumber Beetles – chewed holes present on your plants are often a result of cucumber beetles. Cucumber beetles help the spread of disease so using an insecticidal soap will control this issue. Safer® Brand Insect Killing Soap kills insects on contact without damaging the integrity of your organic garden.

Squash Borers – wilted plant leaves and stems are caused by a squash borer presence.  Safer® Brand Bug Patrol will attach to your hose and can be applied quickly and evenly to your squash plants.

Powdery Mildew – although often mistaken for dirt, powdery mildew is a strain of fungi. Yellowing or stunted leaves, a dirt-like presence on leaves and vines, or premature leaf drop all indicate a possible powdery mildew presence. Safer® Brand Garden Fungicide is compliant with organic gardening and effective in powdery mildew control.
