Top 20 Edible Garden Problems

Common Pests & Problems in Edible Gardens

Edible gardens are certainly not immune to pests and diseases. Pests can take out tender young plant shoots in one night, eat holes in mature leaves and fruit, and leave slimy tracks all over. 

The best way to treat pests is to prevent them:
• Plant disease resistant varieties or edibles that are relatively pest free
Keep the garden clean 
• Maintain healthy soil 
• Provide habitat for natural enemies
• Monitor plants regularly for pests 
• Use an integrated pest management approach

An invertebrate is any animal without an internal backbone including insects, spiders, mollusks, crustaceans, and worms. 

Insects (Arthropods) 

• Have three main body segments, three pairs of walking legs, and antennae 
• Live in the air, on and in soil, and in water
• Majority are harmless or even beneficial; less than 1% are considered pests 
• Aid in the production of fruits, seeds, and vegetables by pollinating blossoms
• Improve soil’s physical condition by burrowing throughout the surface layer 
• Some parasitize or prey on harmful insects
• Serve as food sources for birds, fish, mammals, reptiles, and other animals

Spiders and mites (Arachnids)

• Have two main body segments, four pairs of walking legs, and no antennae
Spiders are generally beneficial because of the large number of insects they eat 

Snails and slugs (Mollusks)

• Move by gliding along on a muscular “foot” 
• The “foot” constantly secretes mucus that helps them move and later dries to form the silvery slime trail

Both snails and slugs are members of the mollusk phylum and are similar in structure and biology, except that slugs lack the snail's external spiral shell. These mollusks move by gliding along on a muscular “foot.” This muscle constantly secretes mucus, which facilitates their movement and later dries to…
