A south Texas producer, interested in increasing the diversity of crop production for local farmers, has found that asparagus can be grown in the Texas heat practically year-round by mimicking the “die-back” that occurs in the plants during dormancy in colder climates.
What temperature is too hot for asparagus?
When temperatures get higher than 85 degrees Fahrenheit or lower than 55 Fahrenheit, root and shoot development slow down. High temperatures cause shoots to open prematurely into feathery fronds, which are poor quality, or grow into misshapen forms.
Can you grow asparagus in tropical climates?
Findings from the study suggests that over 90% success rate of Asparagus production in the tropics can be attained, once farmers make the right choice of farmlands and proper control of other variables like climate, availability of water and selecting the right specie to be grown.
What climate do asparagus grow best in?
subtropical climate
Asparagus is generally considered a temperate/cold climate plant but it is easy to grow in a subtropical climate as it thrives on the rain and has no problems with pests or diseases. Asparagus crown will continue to bear for up to 20 years, making it a worthy addition in any vegetable garden.

What zones will asparagus grow in?
A hardy perennial adapted in Zones 3 to 8, asparagus grows best in well-drained soil with a near-neutral pH between 6.5 and 7.5. The edible part of the asparagus plant is the young stem shoot, which emerges as soil temperatures rise above 50 degrees Fahrenheit in spring.
Can you grow asparagus in Spain?

Does asparagus grow well in Florida?
Asparagus beds in north and central Florida often yield good quality spears for 4 to 5 years before regressing. Gardeners trying asparagus, as many have with varied success, should set out 1- or 2-year old crowns or plant seeds in the spring.
Does asparagus need a lot of water?
Asparagus patches should receive at least one inch of water every week. If they have not received an inch of rain in the last week, soak the soil with water. Asparagus growing in sandy soil should be watered more than once per week in the absence of rain, and heavy clay soils may not need to be watered as often.
Will asparagus spread on its own?
Yes, asparagus will spread as it grows. Asparagus roots can spread out up to 6 feet (1.8 meters) underground. Asparagus ferns (mature spears with foliage) can spread out 3 feet (90 centimeters) above ground. An older, more mature asparagus plant will send up more spears from its larger crown and energy reserves.
How long does it take asparagus to grow?
3 years
Although asparagus can be started from seed, the plants take 3 years to mature, so it is usually grown from 1-year-old crowns. However, the plant can be productive for 10 years or more, so it’s worth the wait. You can start planting and growing asparagus as soon as the soil is workable in late winter or early spring.
Can you grow asparagus in a desert?
Planting High Desert
Plant crowns into prepared beds from Mar 2 – Mar 17, once the soil temperature reaches 50 degrees F. Asparagus is grown from 1-year-old plants or “crowns,” which are planted in early spring as soon as the soil can be worked. Asparagus plants take three growing periods to reach full production.
How do you grow asparagus in Phoenix?
In the low desert of Arizona, start seeds indoors from August – November. Plant transplants outside from November – February 15. Prepare the asparagus bed by adding compost and composted manure to create rich soil. If planting from seed, start seeds in small containers with potting soil or directly in the beds.
