In this blog post, with my own experience I will teach you about the top raised bed gardening mistakes for beginners and how to avoid them to ensure a bountiful and thriving garden.

Starting with a raised garden bed is a great first garden for a first time gardener, so to start right avoid these common gardening mistakes. 

1. Lack of Location Planning

One of the most common raised bed gardening mistakes for beginners is selecting the wrong location for their beds. 

While raised beds are more forgiving than traditional in-ground gardens, they still require the right conditions to thrive.

Why it’s a mistake:

• Not enough sunlight: Most vegetables, herbs, and flowers need at least 6 to 8 hours of direct sunlight daily. In hot climates, like subtropical direct sunlight can vary.  If your raised bed is placed in a shaded area for long periods you may end up with stunted growth.
• Poor drainage: If your raised bed is in a low-lying area, it could be subject to poor drainage and waterlogging. This can make your plants vulnerable to root rot and other plant diseases.
• Environment hazards: You might place your raised bed in a area of excess water or hazards environmental without knowing. 

How to avoid it

• Watch your location first: Ensure that your raised bed gets enough sunlight throughout the day. You can do this by watching how the sun moves throughout the day in the spot you are considering placing your raised beds.
• Level your location: Your location should be leveled to ensure your raised beds ‘drain easily when you water. This is best because if you do not level your ground in an area where water tends to pool your plants will not grow successfully.

2. Not Planning the Size of Your Raised Bed Correctly

Raised beds come in all shapes and sizes, but many beginners make the mistake of jumping into a project without considering the size of the raised beds they need.

Why it’s a mistake:

• Too large: A bed that’s too big can become overwhelming, especially for new gardeners. Large beds also make it hard to manage water, weed, and harvest. If your space doesn’t accommodate a large raised bed you will be stuck with something that doesn’t fit.
• Too small: A raised bed that’s too small may limit the variety and quantity of plants you can grow. 
• Too short raised bed or too tall: Height is important, for some be mindful of how far you are willing to bend down to the garden. Raised beds allow you to help your back while gardening.

How to avoid it:

• Start small: If you’re new to gardening, a 4×4-foot or 4×8-foot raised bed is usually a manageable size.
• Consider accessibility: Ensure that you can reach the center of the bed easily without stepping on the soil. A width of 3 to 4 feet is ideal for easy access from all sides.
• Take out a measuring tape and mark where your potential raised will be. I love my raised beds, they are almost 2 feet high and 6 feet long.

3. Overlooking walkways

Raised bed gardening is all about convenience and you want to make sure you have space around each raised to work in your garden. 

Before installing all your beds allow 3-4 inches between each bed. 

Why it’s a mistake:

• Too close: Not having walks or reasonable space between a raised bed can become overwhelming, especially for new gardeners. It will also make it harder to manage watering, weeding, and harvesting.
• Maintenance trouble: Fitting wheel borrow in between raised is important because you will need to add soil and need to complete other tasks to maintain the raised beds. If you have other equipment be mindful of these sizes as well.  

How to avoid it:

• Start small: If you’re new to gardening, a 4×4-foot or 4×8-foot raised bed is usually a manageable size.
• Consider accessibility: Ensure that you can reach the center of the bed easily without stepping on the soil. A width of 3 to 4 feet is ideal for easy access from all sides.

4. Using the Wrong Soil Mix

Soil health is the foundation of growing your own food garden, and this is especially true for raised beds. It’s a mistake to fill your raised bed with regular garden soil, which can be too dense, clay-heavy, or lacking in essential nutrients.

Why it’s a mistake:

• Heavy, compact soil: If your soil is too dense, it will limit air circulation to the roots and lead to poor plant health.
• Poor drainage: Regular soil may not drain well, causing your plants to suffer from root rot or water stress.

How to avoid it:

• Use a high-quality soil mix: The ideal raised bed soil mix typically contains a combination of topsoil, compost, and organic material like peat moss or coconut coir. A general recommendation is a ratio of 1:1:1.
• Add organic matter: Before planting a new crop add a 2-3 inch layer of compost to the soil to ensure that you are creating nutrient-rich soil.

5. Neglecting to Add Drainage Holes

While raised beds generally offer good drainage, it’s still important to ensure that water flows freely from your bed to prevent waterlogging.

Why it’s a mistake:

• No drainage: If your raised bed has no drainage holes, water can accumulate in the bottom, drowning the roots and causing plants to suffocate. Root rot can be the result if you have no drainage.

How to avoid it:

• Create drainage: Most commercially available raised bed kits have built-in drainage, but if you’re constructing your own, make sure the base is properly designed to allow water to escape by making holes in the bottom of your raised bed if enclosed at the bottom.
• Use a well-drained soil mix: Mixing peat moss and vermiculite into your raised bed soil will help keep your raised bed soil loose and water free-flowing.

6. Overcrowding Plants

When it comes to raised bed gardening, plant spacing is key. Many beginners make the mistake of planting too many vegetables or flowers in one bed.

Why it’s a mistake:

• Limited resources: Overcrowding leads to competition for water, nutrients, and sunlight. This can result in poor growth and disease.
• Increased pest problems: Crowded plants are more likely to harbor pests and diseases, as well as not having enough room to grow to their fullest potential.

How to avoid it:

• Follow recommended spacing: Be sure to check the spacing requirements for each plant species. For example, tomatoes need 18 to 24 inches of space, while leafy greens like lettuce may only need 6 to 12 inches.
• Consider companion planting: Use the available space wisely by planting compatible crops that grow well together and help you have better harvests.

7. Not Rotating Crops Year After Year

Crop rotation is one of the most effective ways to maintain healthy soil and prevent the buildup of pests and diseases. Not rotating your crops year after year is a mistake many beginner gardeners overlook.

Why it’s a mistake:

• Soil depletion: Different plants require different nutrients, and if you plant the same crop in the same spot every year, you risk depleting the soil of essential nutrients.
• Pest build-up: Certain pests are attracted to specific crops. By planting the same thing in the same bed, you may encourage pests to stick around.

How to avoid it:

• Rotate crops each season: Change the types of plants you grow in each raised bed every year to prevent soil depletion and pest buildup.
• Group plants by family: For easier rotation, group plants by their botanical family. For example, after growing tomatoes, you could grow legumes (like beans), which replenish nitrogen in the soil.

8. Underestimating the Power of Mulch

Many beginner gardeners overlook the importance of mulching their raised beds. Mulch is not just for aesthetics; it’s a powerful tool for keeping your plants healthy and helping soil retain moisture.

Why it’s a mistake:

• Weeds: Without mulch, weeds can easily take over your raised bed, stealing nutrients from your plants.
• Water loss: Mulch helps with water retention and retains moisture in the soil, reducing the need for frequent watering.
• Protection: Mulch helps soil keep warm and cool in all types of weather and helps the soil temperature.

How to avoid it:

• Add a layer of mulch: Organic mulch such as straw, shredded leaves, or wood chips can help suppress weeds, and soil moisture, and add nutrients to the soil as it decomposes.

9. Watering Incorrectly

Watering seems like an easy task, but it’s one of the most common areas where beginners falter in raised bed gardening.

Why it’s a mistake:

• Overwatering: Raised beds tend to dry out faster than in-ground gardens, but that doesn’t mean they need to be watered excessively. Overwatering can lead to root rot and fungal diseases.
• Underwatering: On the other hand, not watering enough can cause your plants to wilt and die.

How to avoid it:

• Check the soil: Before watering, check the soil by sticking your finger a few inches into the earth. If it’s dry, water; if it’s moist, wait a day or two.
• Water deeply: Water your raised bed thoroughly to ensure that the water reaches deep into the roots. A soaker hose or drip lines irrigation system can help with this.

10. Ignoring Plant Planning 

Different plants have different growing seasons, and planting at the wrong time can result in poor harvests or even plant failure.

Why it’s a mistake:

• Frost damage: Some plants are sensitive to frost, and planting them too early in the spring can result in cold damage.
• Missed opportunities: If you plant too late in the season, you might miss out on the full growing cycle for certain crops.

How to avoid it:

• Understand your local climate: Know when the last frost of the season typically occurs, and plant accordingly. Most seed packets or plant tags will have information on the optimal planting times.
• Plan for successive harvests: By planning your raised bed garden in stages, you can enjoy a continuous harvest throughout the growing season. Getting my year-round garden planner is most helpful for this.

11. Forgetting to Maintain Your Raised Bed

Even though raised beds are relatively low-maintenance, they still need ongoing care to keep them healthy and productive.

Why it’s a mistake:

• Soil compaction: Not maintaining your raised beds can affect your soil if you don’t keep an eye on replenishing it.
• Wear and tear: Over time, beds need to be fixed or replaced. If you don’t maintain, you will miss these repairs. Need to be done.

How to avoid it:

• Don’t Neglect: Use a calendar or a reminder to walk through your raised beds and see what needs to be fixed or maintained.
• Add compost regularly: Top up your raised bed with compost at the start of each season to keep the soil rich in nutrients.

12. Filling raised bed incorrectly

Filling a raised bed can be costly if you do it wrong. You do not want to break the bank when you have raised beds

Why it’s a mistake:

• Poor harvest: failing to fill raised beds correctly can hurt your plant’s health and ultimately provide you with a weak harvest.
• Waste of money: When you see something is taking all your money, you probably don’t want to do it anymore, and will prevent you from growing food.

How to avoid

• Add organic matter: fill your raised bed 80% weight with organic matter like wood chips
• Consider Your Resources: look at what’s around you and use logs or anything big that will fill a raised bed that is part of nature because it will eventually break down.

13. Not considering your water source

When considering raised beds, don’t forget to be mindful of where your water is going to come from to water everything. You do not want to place your rent raise bed and a location where it will be hard to have a water resource.

Why it’s a mistake:

• More work for you: If you place your beds in a place where it’s gonna be hard to bring water to it you will bring more work to you and you will be less likely to garden.
• small harvest: your water is limited, you will have a small harvest or not one at all if you don’t have enough water for your plants.

How to avoid it:

• Place closer to home: please raise beds closer to home so you have access to water from your house or well. It will make your life easier.
• Use water resources: using water resources like drip irrigation system, and water timers will save you water and it will be easier to set up.
• Placing a self-watering system is also a great option, check out my video below on how to make your DIY OLLA.

14. Using the wrong materials

Not considering the materials of your raised bed can be a disaster. Eventually, things will break down, and you want your raised beds to last as long as possible.

Why it’s a mistake:

• Limited longevity: Some materials have a longer lifespan than others. You want to make sure the material you use will withstand any type of condition since they will be outside.
• Chemical safety:  some chemicals can leach out from certain materials and can be transferred to your soil.

How to avoid it:

• Use hardy wood material: Using a cedar or Redwood option would be a long-lasting option if you’re going the wood route
• Consider metal of brick: Galvanized steel, and bricks or cinder blocks are very, very durable and weather resistant.

15. Overlooking plant protection

Gardeners can forget the different weather fluctuations that they encounter when growing in raised beds. protecting and extending your season should not be overlooked.

Why it’s a mistake:

• Short growing season: If you don’t protect your plants from certain weather, you will have a shorter growing season.
• Overwhelming pest pressure: implementing certain protection will protect your plants from pests as well. 

How to avoid it:

• Season Extenders: Build a raised bed cover to protect your plants from harsh weather conditions. 
• Row cover: Place raised bed hoops in your raised bed and attach a lightweight row cover that will still let light and water pass through. 

16. Not planning the right plants

Picking the right plants to plant or sow in raised beds will help you have a bountiful harvest at the end of your growing season.

Why it’s a mistake:

• Too little spacing: planting the right things in your race bed will help prevent overcrowding and ensure the right spacing for specific crops.
• not enough sunlight: not planting the right vegetables herbs or even flowers in your raised bed might result in a decreased amount of sunlight a specific plant gets and hinder its growth

How to avoid it:

• Get a planting guide: Search out resources that tell you a list of plants that work best in a raised bed, especially in your climate.
• Consider vertical gardening: to ensure any type of plant will grow in a raised bed, place a trellis right up against your bed to help vining plants or any crop to grow upright to help you with space, and sunlight.

17. Not labeling plants

It will be hard to keep track of what you are growing when labels aren’t used.  New people who are new to the gardening game might not be able to identify plants through their different stages of growth.

Why it’s a mistake:

• No proper care: A bed that’s too big can become overwhelming, especially for new gardeners. Large beds also make it harder to manage watering, weeding, and harvesting.
• Lack of Education: The lack of labels will hinder educational value when knowing what plants are & how they grow. 

How to avoid it:

• Use reusable labels: Plastic plant labels with a smooth side can be easily found & written on.
• Consider making your own: To ensure the quality of our labels you can use wood, stainless steel labels or any other durable material to help label your plants.
• You can also number or label your raised bed to stay organized.

18. Remembering to refresh the soil

Soil in raised beds needs to be refreshed to help with the depletion of nutrients in the soil. This will ensure your plants will get the necessary nutrients for your plants to grow successfully.

Why it’s a mistake:

• Nutrient Depletion: If you do not have fresh soil it will result in nutrient-deficient soil, and will directly affect your harvest at the end of the growing season.
• Soil quality: soil quality depends on the life of your crops, so without it, you will have welcome plant diseases. 

How to avoid it:

• Add compost & amendments: Adding organic matter like compost and amendments to your soil will help with the health of your plants. 
• Soil Test: Soil testing will help you know what your soil is lacking to help adjust. I have used this Soil Test and it helped open my eyes to the soil I have.

19. Not maximizing your space

You can easily make the mistake of not utilizing your growing space with the wrong raised beds by getting them too large or not utilizing potential vertical growing space. 

Why it’s a mistake:

• Poor bed placement: Not seeing how your sun exposure hits your growing space can lead to poor raised bed placement that will affect the growth of your crops
• Improper planting space: Growing plants that need certain space requirements will not grow successfully if you’re not maximizing your space with your raised beds. 

How to avoid it:

• Poor bed placement: Not seeing how your sun exposure hits your growing space can lead to poor raised bed placement that will affect the growth of your crops.
• Consider accessibility: Ensure that you can reach the center of the bed easily without stepping on the soil. A width of 3 to 4 feet is ideal for easy access from all sides.

20. Not being mindful of Garden aesthetic  

This one is the last because it might not be as important but if you care about how your raised bed garden setup looks it might be important to you. If you want a specific look you might regret not sticking to certain raised beds from the beginning to get the look you dreamed of. 

Why it’s a mistake:

• Loss of Value: If you do not have a nice garden aesthetic can decrease the value of your property. It would be a mistake to not keep up and have your race bed garden well-maintained.
• Mental Health: if you feel to prioritize a garden, aesthetic A good morning how are you Studies show that exposure to natural beauty, including a well-designed garden, can reduce stress, improve mood, and promote feelings of 
• Too short/tall

How to avoid it:

• Elements factors: Color combinations, plant textures, spatial arrangements, and water features all contribute to the overall aesthetic appeal of a garden’s manageable size.
• Creativity: Ensure Garden design allows individuals to express their style and creativity through plant choices and landscape features.
