Extreme Temperature Effects 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.
How hot can asparagus tolerate?
Temperature. Once soil temperatures reach above 50 degrees Fahrenheit, asparagus will start putting up new shoots. However, the optimal temperature range for production is between 75-85 degrees Fahrenheit during the daytime, 60-70 degrees at night.
What temp does asparagus like?
70 to 85 degrees Fahrenheit
During the growing season, asparagus prefers a temperature of 70 to 85 degrees Fahrenheit during the day and 60 to 70 degrees at night. In the spring, it will begin to grow shoots when the soil temperature reaches 50 degrees. Any frost after the shoots start growing will cause discoloration.
Can I cut asparagus back in the summer?
A Summer Harvest
From spring to midsummer*, let it recharge its batteries, storing ample energy reserves in its roots. Then, in mid-July, cut the plants back severely: to the ground or almost so. The plant will respond to off-season pruning by producing new shoots that will be ready to harvest in about 4 to 6 weeks.
What climate is best for growing asparagus?

Can you grow asparagus in hot weather?
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.
Can you grow asparagus in warm climates?
Asparagus Varieties
Varieties suitable for warmer climates include UC157, De Paoli, Apollo and Atlas. These respond to drought dormancy. UC157 and De Paoli are commonly grown in California.
Does asparagus need full sun?

How many times a year can you harvest asparagus?
Early in the season, you might harvest 7- to 9-inch spears every two to four days. As air temperatures increase, harvesting frequencies will increase to once or twice per day. You can have up to 24 harvests per season, after which you can allow crowns to fern and grow out.
How often should you fertilize asparagus?
two times every year
Because asparagus remains in its home for many years, it’s important to feed it and fertilize it regularly so that it can stay strong and keep producing. Asparagus should be fertilized two times every year: First Fertilization: Fertilize in the early spring, just before or as the new spears start emerging.
What month is best to plant asparagus?
Planting. Asparagus is grown from 1- or 2-yearold crowns planted in January or February, or as soon as the ground can be worked. Crowns can also be grown from seeds planted in flats or peat cups. It takes at least a year to grow a good crown.
How deep do asparagus roots go?
Asparagus roots grow to an astonishing size of 5–6 feet (1.5–1.8 meters) in diameter and 10–15 feet (3–4.5 meters) deep. These plants, sometimes mistakenly called asparagus ferns, are also highly invasive. For this reason, it’s sometimes pejoratively referred to as a perennial weed.
How big should an asparagus bed be?

Why is my asparagus growing skinny?
Lack of Water. These plants are moderately drought tolerant and will survive without a lot of water, but dry conditions will cause them to grow more slowly and produce thinner, weaker stalks. During the first couple of growing seasons, plants should receive one to two inches of water per week.
How do you grow asparagus in a tropical climate?
Plant crowns (roots) 20-40cm apart and a few cm (1 inch) deep in well manured soil. The asparagus shoots grow in spring. Harvest the shoots which are bigger than 1-2cm/half-inch in diameter. Leave the rest to grow into the leafy ferns (1.5m/5-6ft tall) which will feed the crowns to give a crop next year.
