Rabbits are very popular at Easter and adored by little girls the world over, but they are voracious pests that will attack your garden. A single jackrabbit may eat as much as 0.45 kg (1 pound) a day... and they might get the food out of your vegetable beds. Rabbits devour many of the leafy vegetables and edible plants that gardeners enjoy, but there are some garden vegetables that rabbits won't eat.
Potato is a popular crop for amateur and professional vegetable gardeners, but it's not attractive to rabbits. Grow potatoes only in soil temperatures below 27.5 degrees Celsius (80 degrees Fahrenheit), optimally between 15.5 and 21 degrees Celsius (60 and 70 degrees Fahrenheit). Potatoes are very cold hardy, and will survive light frosts. Plant early potatoes in March or April and late-season plants in early July.
Potatoes should be planted 2.5 to 7.5 cm (1 to 3 inches) deep in soil, with at least 25 cm (10 inches) of space between plants. Give the plants well-drained, rich soil for best growth. Add 10 to 15 cm (4 to 6 inches) of straw mulch over the potatoes to prevent weed growth.
Rhubarb is another cool-season vegetable that rabbits traditionally do not eat. Regions with cool winters that reach 4.5 degrees Celsius (40 degrees Fahrenheit) and lower and less than 24 degrees Celsius (75 degrees Fahrenheit) in summer are ideal for rhubarb. Give the plant rich, well-drained soil and a sunny planting site for the best growth.
Rhubarb should be planted in autumn, after summer garden plants have gone dormant for the season. Plant rhubarb crowns 2.5 to 5 cm (1 to 2 inches) deep in rich, well-worked soil. Add 7.5 to 10 cm (3 to 4 inches) of straw mulch once the plants begin to sprout. Begin harvesting rhubarb in the second year of growth.
Alliums, or spring onions, are edible and attractive enough to be grown as ornamental garden plants, but rabbits usually don't eat them. Alliums grow in dense, shrub-like clumps spreading as much as 30 cm (1 foot) wide and up to 60 cm (2 feet) tall. The long, tube-like leaves are hollow. Oval-shaped, edible onion bulbs grow under the soil.
Plant allium in full sunlight if possible, but the plant will tolerate partial shade if necessary. Allium is best grown in USDA hardiness zones 6 through 9, and may be harvested all year long.
