Can a tomato vine keep bearing, even a year after it had been implanted? It definitely sounds far-fetched until you consider that tomato plants are technically perennial vines. They aren’t programmed with nature to perish after crop is over. We just think of these that way because several people live where tomatoes can survive the colder months. In case you have an adventurous spirit, a little bit of luck and the ability to stretch the growing season — or in some cases your definition of what exactly a “tomato” is — you may be able to grow new tomatoes with last year’s plants.
Why Annuals?
Though they’re technically nonhardy perennials, that very nonhardiness means that most folks in the North hemisphere must resign themselves to getting only one growing season each tomato plant. . The frequent tomato (Lycopersicon spp.) Types incorporate standard-size beefsteak or plum tomato vines; dwarf container plants using normal-sized tomatoes; and cherry, pear and grape tomatoes, which can be smaller both in fruit and plant size. All these are generally treated as annual plants in the continental U.S., meaning they’re seeded in the spring and harvested in the summer and early fall. The vines themselves have been removed in fall to prevent any insects or diseases from overwintering in the ground.
Tropical Gardens
In tropical regions outside of the continental U.S., even common tomato vines can live for over one year. Although it is a short-lived tomato plants may bear fruit for over one year in parts of the world that never dip below 65 degrees Fahrenheit. In case you have a greenhouse and can keep it heated during the cold months, consider placing an experimental beefsteak, plum or grape tomato plant one of your tropical flowers. You may coax at least two years of productivity in the vines. Grow your greenhouse tomatoes in containers so they can spend the slopes on the patio, rather than overheating in the ocean.
Volunteers
While you may by no way count upon it, a phenomenon known as “volunteer” tomato plants might occur in your garden or even your compost pile. The spring following a previous year’s tomato harvest, you may observe the familiar foliage of a young tomato plant springing upward. Volunteer tomato vines occur either by a fallen seed germinating in the original plant or by a side-shoot of their original plant that was overlooked during plant and soil removal. Seeds or bows can develop either near the original growing website or within a compost or deny pile where the soil and old plots were deposited. Keep in mind, that since disease spores can multiply after overwintering in the soil, volunteer tomatoes are more vulnerable to tomato diseases like black spot.
Alternatives
For gardeners in subtropical, medium or even chilly regions, there are perennial plants that act as options to tomatoes. The wolfberry plant (Lycium barbarum), also referred to as the goji, has fruit with a tangy-sweet taste reminiscent of some cherry tomato kinds. Fresh goji berries are more savory than dried berries. Wolfberry plants, which also bear edible leaves, thrive in U.S. plant hardiness zones 5 through 8. For mild regions, like parts of California, consider the perennial goldenberry (Physalis peruviana), also referred to as the Cape gooseberry. These plants are hardy to zone 8, bear little fruits encased in papery husks that are often described as having a somewhat nutty, tomatolike taste. A close relative that does well in colder regions is the strawberry tomato (P. pruinosa), or husk cherry. It shares lots of the same attributes of Cape gooseberry, but it is technically an annual that self-seeds so prolifically you can treat it like a perennial.
