Organic gardeners can take advantage of the fact that juglone moves poorly through soil by installing raised garden beds. Even if your garden bed is located away from the tree’s canopy, this technique may ensure the success of very sensitive plants like tomatoes, which wither away when in contact with any root portion of the walnut.
As organic gardeners are accustomed to making compost out of all organic materials generated by the garden, the question of walnut litter disposal naturally arises. The extremely high juglone content of black walnut hulls makes them an unwise addition to your compost bin. You can compost the leaves with the caveat that plants very susceptible to juglone toxicity may perform poorly when treated with this compost.
Promoting good drainage is another way to protect plants from juglone toxicity. Double dig the soil to a depth of two feet, and incorporate enough compost or well-rotted manure to create a mix of 2/3 soil and 1/3 organic amendment.
The greatest amount of the toxic juglone is present in a black walnut’s buds,[link widoczny dla zalogowanych],[link widoczny dla zalogowanych], nuts, and roots. A gardener can prevent juglone toxicity in many plants by picking up the tree’s litter every day. This is no small chore, as one mature tree may drop enough nuts to fill a 5-gallon bucket every day for weeks during ripening.
If your lot is covered with black walnut trees, you’ve no choice but to grow plants resistant to the effects of juglone:
The black walnut tree, or Juglans nigra, is widespread throughout the growing zones 5-9 in North America. Like any native tree, the black walnut has its attributes; including providing the homeowner with a long-lived shade tree whose canopy may spread 50 feet. The tree also attracts wildlife, especially squirrels that spend hours in its canopy cracking nuts, and woodpeckers that hunt the deeply crevassed bark searching for insects.

These virtues aside,[link widoczny dla zalogowanych], black walnut trees present the organic gardener with the laborious chore of cleaning up bucketfuls of walnut litter in the autumn. These fruits dropping from the skull-cracking heights of 70 feet not only leave the gardener wanting for a hardhat, but are also the source of juglone, a toxic substance that stops the respiratory process of many garden plants. If you have one or more black walnut trees in your yard, you must avoid the effects of juglone toxicity with a plan of action.
Enterprising gardeners may find value in the nuts themselves as a crop. Walnut hulls are exceedingly tough; some harvesters resort to driving over the nuts in an attempt to get at the nutmeats. In the hulling process,[link widoczny dla zalogowanych], gardeners may also discover why walnut hulls are the source of an indelible dye. If you’re willing to go through the work to get a cup of nutmeats from two pounds of unshelled nuts, bake yourself a congratulatory walnut cake afterwards.
