The Basics Of Growing Carrots In Arizona

Growing carrots in Arizona is composed of planting, maintenance, and harvesting. There are some practices that you must meet with these steps unique to Arizona because of the state’s conditions. According to the University of Arizona, the USDA hardiness zones range from 4b to 10b, which means the state’s climate is arid. 

Still, it’s feasible to grow carrots in Arizona by complying with the requirements for the crop’s optimum growth and health. In Arizona, farmers sow 1,000,000 seeds per acre. Regardless of planting on a large scale or small scale, read down below on how to make your Arizona carrot farm a fruitful endeavor. 

Growing Carrots In Arizona


How To Grow Carrots In Arizona?

Plants grow best if the climate in the region is similar to their hardiness. Since the hardiness zones of carrots are from 3 to 10, it is possible to grow them in Arizona’s 4 to 10 zones. However, please note that even though they are hardy, prolonged exposure to extreme cold can affect carrot health. 

An excellent planting strategy to keep harvesting quality carrots is by using a greenhouse. Refer to and learn more about greenhouse gardening. This ensures that you consistently get a high yield of quality vegetables because you’ve blocked exposure to extreme outdoor conditions and challenges. 


Growing carrots in Arizona



The best time to plant carrots in Arizona is from August through April since they grow best in early spring and late fall. Choose an area that will receive 6 to 8 hours of full sun with well-drained sandy soil. Sow the seeds at half an inch deep, and you can have a continuous harvest if you plant every three weeks. 

Growing carrots in the greenhouse will protect them from extreme temperatures that can cause discoloration. The ideal temperature for them is the cold conditions in spring to fall or 75°F at day and 55°F at night. Carrots will take up to 21 days to sprout.



When it comes to maintenance, water the sprouts regularly to encourage continuous growth. The seeds will also not germinate in dry soil, so remember to keep it moist for ten days after planting. It would help if you thinned the seedlings using scissors 3 inches apart to create enough room for each crop as they reach maturity. 

For feeding, two tablespoons of fertilizer per 10 feet of the row are enough. The Texas A & M University recommends fertilizing the carrots again when they reach 8 inches in height. And like with any plants, address pests and weeds early on. 



The key takeaway in harvesting carrots in Arizona is that you want to do it before summer comes. The heat can damage the carrots if you leave them in the ground in this condition. However, it’s important to note that it’s best to leave carrots in the field until they turn vibrant in color.

This means that they are ready to eat, and you’ll notice that the top of the roots is about an inch in diameter. In terms of storage, long carrots are suitable for storing, while fresh consumption of the shorter ones is best. And since carrots are biennial, expect to wait two seasons before they flower. 

Depending on the variety, you might be ready to harvest your vegetables in 60 days. Leaving them longer can lead to larger carrots, but their flavor may also diminish. It’s a good practice to sow carrots every three weeks from spring to summer, so you don’t lose flavor for long. 


Can You Grow A Carrot From A Carrot? 

You can grow a carrot from a carrot in a sense that you’ll be using the carrot tops. This is because the vegetable part is the plant’s taproot, and you can’t use it to regrow carrots. On the bright side, the part that you usually throw away, which are the tops, can grow into a carrot. 

There are many ways to grow a new plant from the carrot tops. The easiest method is by growing them in water. It’s as simple as using an inch of the root and then balancing it on top of a small glass with water.


How Long Does It Take To Grow A Carrot In Arizona?

In Arizona, growing carrots can take 60 to 100 days. As mentioned earlier, these crops are biennial, so it takes two growing seasons before they mature. However, harvesting carrots at the end of the first growing season is possible when the roots turn thick and long. 

If you didn’t harvest the vegetables, the carrots could use the nutrients on the ground for the following year. The crops will grow back in spring if you leave them over winter. And in the fall, the plants will die after they seed. 


How Many Carrots Do You Get From a Plant? 

One carrot top can yield six to seven stumps. If you’re planting in rows, you can harvest up to 10 pounds of carrots. On the other hand, using a foot square planter allows the harvest of up to 40 carrots. 


What Vegetables Grow Best In Phoenix Az?



Artichokes grow well in Phoenix. They grow best in the fall in an area that receives afternoon shade. Watering them is crucial, and according to farmers, it’s natural for artichokes to look dead during the summer. 



You can plant basil in Phoenix during the fall or winter. You can also grow this herb alongside oregano and rosemary in the greenhouse, as high heat can slow down its growth. Additionally, basil is annual, so expect to replant every year. 



Phoenix provides suitable conditions for broccoli. It is an easy crop, and you can harvest it in spring if you plant it in fall. Remember to place broccoli in an area that receives sun. 


Chilis and peppers

Spring and fall in Phoenix are excellent for hot and sweet peppers. They are not suitable for extreme hot or cold, so planting them in a greenhouse is a sensible practice. You can plant them in early March or the fall. 



Dill is full of benefits, and it is easy to grow in Phoenix. You can start it in early spring, and you’ll get an abundant harvest because it grows fast. Once summer comes, you’ll notice that your plant got taller. 



A viable summer crop for the Arizona desert is eggplant. However, do note that frost can damage them. The best time to plant eggplants is in March. 



You can plant healthy greens like spinach in Phoenix in the fall. You can harvest it in spring, and maintenance is not even meticulous. Besides spinach, swiss chard also grows well in this area. 



Farming and gardening in Arizona require additional practices to protect the crops against extreme conditions. If you’re interested in growing carrots in Arizona, it’s essential to understand every step from planting, maintenance, and harvesting. Carrots are biennial, so expect to wait two seasons before they flower.

Other than carrots, Arizona can also grow artichokes, basil, broccoli, chilis and peppers, dill, eggplants, and spinach. Most of them will even grow better in a greenhouse since indoors will protect them from high heat and frost. Overall, planting in Arizona is straightforward as long as you plan.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
