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

Are you interested to learn how to start an avocado farm? Embarking on this journey requires time, effort, and commitment. Plus, you need to consider a number of factors including soil preparation, as well as weather conditions.

You’re probably aware that avocado trees or Persea spp, are originally from Mexico. This explains why one of the famous Mexican cuisines include avocado-based guacamole.

You can choose to grow avocado trees indoors or outdoors. If you plan to grow them in a hobby greenhouse or at home, all you have to do is to sow the seeds in pots. When they’re grown outdoors, avocado trees can grow up to 40 feet. You can al

Moreover, these trees thrive well in regions where the weather is mostly warm and sunny. However, don’t expect them to grow in areas that experience extreme temperatures during the summer and winter.


Avocado: The Superfood

Did you know that the global demand for avocados has been steadily increasing? Aside from the fact that its fruit is known for its full, buttery flavor and rich texture, it’s also packed with loads of essential nutrients that are good for your body.

A single serving of avocado fruit contains vitamin K, vitamin C, folate, potassium, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin E, manganese, magnesium, iron, copper, zinc, and vitamin A.  It also has protein, fiber, and healthy fats. If you’re on a low-carb plant food diet, you’d want to incorporate avocados into your diet.


What are the Growing Requirements of an Avocado Tree?

Since avocado trees need to be grown in warm semi-humid climates, they only grow in U.S. Department of Agriculture (USDA) plant hardiness zones 8 to 11. However, it’s important to note that while avocado trees may be grown in those zones, they don’t always thrive well in areas that get extremely hot during the summer or frosty, chilly, or snowy in the winter. This implies that the ideal environment for an avocado tree should have moderate temperatures all-year-round.


What are the 3 Primary Groups of Avocado Trees?

If you’re planning to start an avocado farm, you need to know the 3 main groups of avocado trees: Guatemalan, West Indian, and Mexican. Each type has its own ideal growing range.


Guatemalan Avocados

A Guatemalan avocado is known for its hard skin that features plenty of warts.


West Indian Avocados

This type of avocado tends to flourish in warm climates. Unlike the Guatemalan avocado, a West Indian avocado has thin and shiny skin and could weigh up to 5 pounds.


Mexican Avocados

A Mexican avocado thrives well in tropical highland areas. Compared to the other avocado groups, the Mexican avocado is more tolerant of cold weather. In fact, it can manage to survive even when temperatures drop to 26˚F.

Moreover, this type of avocado produces smaller fruit that weighs less than a single pound and its skin has a distinct papery-smoothness to it.


Expert Tips on How to Start an Avocado Farm

Unless you’re willing to take on a long-term project, spend a considerable amount of money on planting, and wait for a period of 3 to 5 years for your first harvest, don’t get into avocado farming. However, if you’re willing to go through the whole nine yards to enjoy top yields for many years, check out this guide:


Tip #1: Plant them in areas where the temperatures are consistently cool

Be sure to plant your avocado trees in cool temperatures that can range between 68˚F to 75˚F on a daily basis to avoid fruit drop. However, when they’re flowering, or when they’re starting to bear fruit, the humidity levels shouldn’t go below 50% at midday.


Tip #2: They don’t like wind

In case you’re not aware, avocado trees have brittle branches that easily snap off. For this reason, it’s best not to plant them in areas that are mostly windy because wind can cause considerable damage to their fruit.


Tip #3: Most of them need proper irrigation

If your avocados are rain-fed, they need to have at least 1,000 mm rainfall spread out throughout each year. Before their flowering season, avocado trees require a drier season that lasts for about 2 months. On a weekly basis, avocado trees need about 25 mm water.

It’s extremely important to test the quality of irrigation water because if its pH and bicarbonates are really high, they trigger a build-up of free lime in the soil. You also need to remember that high levels of sodium and chloride can have a negative impact on your avocado plants.

Since the plant’s roots are shallow, the ideal way to apply water is via a micro-sprinkler or drip. This ensures an even distribution throughout the avocado tree’s root area.

Moreover, proper moisture control needs to be ensured in the root zone because this area tends to easily dry up.


Tip #4: Determine the soil’s suitability and prepare it accordingly

You can’t just plant an avocado seed on soil that hasn’t been prepared accordingly. To prepare the soil for planting, you need to dig soil profile pits throughout your farm. Make sure that the pits are 1.5 m deep.

Only a single put per ha is required. However, you need to dig more pits if the location is non-homogenous or hilly. Check the color of the soil, its texture, structure, patches, sitting water, concretions, hardpans, stones, and gravel.



Grow Your Avocado Trees in a Hobby Greenhouse!

Since avocado trees require specific levels of temperature and humidity, you’ll find it easier to grow them in a hobby greenhouse. The enclosed space allows you to customize the environment to meet the needs of your plants. What’s more, it protects them from strong winds and the constant threat of pests.

Learning how to start an avocado farm outdoors is great, but growing them inside a hobby greenhouse is even better.
