Top 8 Best Vegetables to Grow in Portland Oregon

Some of the best vegetables to grow in Portland, Oregon, including cabbages, broccoli, beets, and other greens.  Portland, Oregon is known for its scenic views, majestic waterfalls, and picturesque hiking trails. However, among these things, Portland is also known as a gardener’s paradise. It’s all due to the wide variety of plants that thrive in the area. 

Although Oregon often experiences cold spells lasting for weeks, the temperatures are mild most of the year. Aside from the temperature, irrigation, soil types, nutrients, and care, other important factors affect the growth of your plants. 

Growing Crops in a Greenhouse

Location is another essential factor to consider when planning your gardening activities, especially during fall and winter seasons. For your plants to survive, they need to adapt to the microclimate and the local climate. 

You can check the USDA Plant Hardiness Zone Map to know the climate and hardiness zone in your region. Using this map, you can see the different types of plants that best grow in your area and the average minimum temperatures. Portland generally has hot, dry summers and cold, bitter winters. 


Best Vegetables to Grow in Portland Oregon

Here are some of the best vegetables to grow in Portland, Oregon:



It’s easy to grow broccoli in Portland, Oregon. Broccolis thrive in cooler areas, and it’s not a fan of excessive heat. You can grow it from transplants, starting from seedlings. However, broccolis need a lot of water. The soil should remain moist throughout the growing season. 

Broccolis attract harmful pests, including cabbage worms, root maggots, and aphids, so make sure to watch out for these critters. 



Just like broccoli, beets are a cool-season vegetable. They can even survive near-freezing temperatures! Beets grow quickly in well-prepared soil, and you can harvest them about two months after planting. Unlike other plants, you don’t have to deal with pests and disease problems when growing beets. 



If you think you can’t plant greens in Portland’s cool climate, think again. Many green leafy vegetables grow well in Portland, such as spinach, arugula, kale, and chard. Since you’re growing greens mainly for their leaves, you need to make sure that your soil contains plenty of nitrogen. Don’t forget to water them as well so they would grow fast. If your plant grows slowly, its leaves may turn out tough.

While greens can grow in Portland, they can thrive better inside greenhouses. This allows your plants to stay clean and protected from rain and hail. 



Lettuce can easily grow in Portland, Oregon. You can directly plant the seeds in your garden, but it’s easier if you plant it indoors. Lettuces don’t need direct sunlight to germinate. Additionally, you can easily transplant the seedlings. 

As with other types of greens, it’s important to protect your lettuce from heavy rain and hail. Your soil should be consistently moist, and it should contain plenty of nitrogen to grow the best lettuce. Otherwise, it will taste bitter. 



Cabbages also grow well in cool temperatures. Growing them in humid areas may cause their heads to split before you get to harvest it. Since you need the cabbage for its leaves, the soil should also have a lot of nitrogen, and you should water it consistently. 



Potatoes are easy to grow, especially in light, sandy soil with minimal fertilizer and water. Plant your potato patch in sunny areas where they could (ideally) get at least six hours of sunlight per day for the best results. 



Carrots prefer to be planted in deep, loose soil during cool temperatures, preferably early spring and late fall. If planted in heavy soil, your carrots will mature slowly, resulting in unattractive and rough roots.  Carrots should be seeded directly, and the soil should be kept moist, so the surface never crusts over. You can place coconut fibers on top to retain moisture.



Tomatoes need at least eight hours of sun exposure. These plants have a long growing season, so it’s best to transplant them rather than seeding them directly into the garden. To grow sweet tomatoes, make sure to get the right balance of sun and heat. Since Oregon has a cooler climate, it’s best to grow your tomatoes in a greenhouse so you’ll be able to control the temperature. 


Growing Crops in a Greenhouse

Greenhouses enable you to control the climate inside the greenhouse, regardless of the current weather. This allows you to grow different types of plants that never would’ve survived in your area. You can even customize your greenhouse by adding heating and cooling system, lights and shades, and ventilation. 

If you have larger greenhouses, you can divide them to create climate zones. In this way, you can grow different types of plants within the same structure. 

Many plants cannot survive in freezing temperatures, so be sure to pick your harvest immediately. You can protect immature fruits from mild frost by using baskets, burlap, blankets, or canvas sacks. Since Oregon is prone to heavy rains, your leafy plants are more vulnerable to pests and diseases. 

Heavy rainstorms can saturate the soil, attracting slugs, and encouraging the spread of leaf diseases. Protect your garden from unwanted pests, rain, wind, and hail by using greenhouses. 

Other advantages of growing plants in a greenhouse include the following:


  • longer growing seasons
  • create an ideal growth environment
  • grow plants without dangerous pesticides
  • save energy

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.
