How can something so beautiful be so destructive to a veggie garden? A black walnut tree two yards away has destroyed my veggie garden in a matter of days. I figured I learned the hard way and maybe can spare a few folks some heartache by sharing a bit of info about black walnut trees.
The trees produce a substance called juglone which many plants can’t tolerate being around. Its secreted through all parts of the tree; the roots, the nuts, the leaves and even the rain that falls off of its canopy. Because the canopy and roots can be pretty extensive, it is best to plant veggies and other susceptible plants at least 50 feet away. Be sure to pick up leaves and any nuts that may have fallen into your garden (or been brought by squirrels!)
- susceptible to juglone: tomatoes, eggplant, peppers, raspberries, pears, potatoes, asparagus, cabbage :(
- plant these instead: beans, onions, carrots, beets, corn, squash, melons and move your other veggies as far from the tree as you can
- we seem to be having luck with: kale, swiss chard, basil, thyme, parsley, lavender, chives, camomile, garlic and fennel
We are already planning for next year and hope London is ready for some front-yard veggie gardens! xo
