Beginners Guide to Raised Bed Gardening

Raise beds are great for growing vegetables and flowers but require a significant investment in time and effort. If you want to get started with raised bed gardening, beginners often make some common errors. Read on so you don’t make those mistakes and handle your raised bed more easily.

10 Mistakes to Avoid When Gardening In Raised Beds:

1. There is too much space between raised beds

There is too much space between raised beds

Raised beds are great because you can grow taller crops like tomatoes and cucumbers. However, one of the drawbacks of raised beds is that they’re typically wider than traditional gardens.

If you’ve ever tried to walk around a raised bed, you know what I’m talking about. You’ll probably crush some soil underneath your feet every time you step.

This causes compacted soil, making it harder for roots to penetrate the ground. And since roots are essential for plant growth, this leads to stunted plants.

Soil compaction happens naturally when you use heavy machinery such as tractors, wheelbarrows, etc. Or, it could happen when people walk over the same area repeatedly.

The good news is that there’s a simple solution. We must learn how to keep our soil loose enough to breathe while still being strong enough to support our plants.

2. Weed Barriers Not Applied

Weed Barriers Not Applied

If you don’t use a weed barrier down at the base of the bed, you’ll likely find yourself pulling out some nasty weeds along with those beautiful flowers.

If you’ve ever had a lawn mowed under your raised beds, you know how fast grass grows once it’s exposed. And if you haven’t been keeping the grass trimmed around your raised beds, you’ll probably see weeds pop up quickly.

Here’s why: Grassroots spread like crazy, especially when they’re growing underground. First, they send out root hairs that break into tiny pieces of soil called “rhizomes.”

These rhizomes are small plants, but they keep sending out more rhizomes. Eventually, the grass reaches the ground’s surface and starts producing leaves again voilà. You have grass.

You must cover your raised beds with weed barriers or fabric mulch to prevent this. The fabric mulch comes in different materials, depending on where you live. For example, you might find plastic mulch in California and straw mulch in New England.

3. Plants Are Too Tall

When we think of raised beds, we envision them filled with tall plants like tomato vines. While these plants look nice, they cause problems in terms of drainage.

Since you’re trying to create a dry environment inside your raised beds, having too tall plants can lead to waterlogged soil. That’s not ideal for your plants.

It may be tempting to plant vegetables and other annuals immediately, but waiting until the weather gets cooler before introducing new plants to your garden is best.

This gives your plants a chance to acclimate to their surroundings. Plus, you want to give your plants plenty of room to grow. So make sure you leave lots of space below the plants.

4. No Mulching

Mulches help keep moisture in the soil and protect against erosion. They also serve as a natural fertilizer and help retain nutrients. But without mulch, you’re exposing your soil to potential threats.

For starters, bare soil attracts animals and insects like rabbits, mice, birds, and deer. When these pests eat your plants, they can carry diseases that kill your entire crop.

But even if you avoid animal attacks, you should always use a thick layer of mulch. It helps prevent soil erosion by holding back rainwater and snow melt. It also keeps the soil warm, which encourages plant growth.

5. Using Irrigation without Proper Drainage

Using Irrigation without Proper Drainage

There are two key things to consider when watering your raised beds. First, you want to ensure that any irrigation system you install drains properly. You don’t want standing water collecting anywhere near your plants.

Second, you want to ensure enough space between your plants so that the excess water doesn’t run through the middle of the row and soak your neighbors’ plants. A simple way to do this is to set aside just a few inches between rows.

6. Not Watering Enough

If you aren’t giving your plants adequate water, they won’t thrive. And no amount of fertilizer will compensate for the lack of moisture. Over-fertilizing can result in stunted growth because plants take time to absorb nutrients.

7. Failing to Add Nutrients

Plants need both nitrogen and phosphorus to get strong and healthy. If you feed your plants nitrogen but neglect to add phosphorous, you’ll have weak stems and leaves.

8. Planting Too Many Vegetables at One Time

Planting Too Many Vegetables at One time

Vegetables often require more sunlight than most crops. That means they need at least six hours of direct light each day. However, many people only have four hours of sunshine during summer.

To make matters worse, you can end up with overcrowded plants. When that happens, your plants can’t access much oxygen or nutrients. As a result, they become stressed and less likely to produce fruit or flowers.

9. Forgetting About Insect Pests

Many bugs and weeds prefer warmer temperatures than those found indoors. Unfortunately, that means they’ll probably show up in your vegetable garden sooner rather than later.

10. Getting Started Too Early

The last mistake beginners make is starting their gardening too early. You want your plants to acclimate to outdoor conditions before growing them outside.

It’s better to wait until spring again before planting anything outdoors. Then, once the temperature rises above freezing, you can start growing plants outside.

How can you avoid these raised bed mistakes?

Raised beds are an excellent way to grow vegetables in your backyard without spending money on soil or fertilizer. However, if you’re not careful, they can be very dangerous. So here are some common mistakes when building raised beds.

Step 1: Don’t Leave Your Bed Unfinished

When raising bed construction, it’s best to leave the frame unfinished until everything else has been completed. For example, don’t put down the plastic liner until you’ve planted your seeds. You want to ensure that the bed isn’t leaking or getting wet.

Step 2: Make Sure Each Side Is Level

Raised beds come in different sizes, so it’s important to check both sides of each bed to ensure they’re even. Use a string line or measuring tape to do this. It’s also important to fill the spaces between the plants; otherwise, roots may grow out of nowhere.

Step 3: Keep Out of Reach of Children

You never know what kids might find in their yards, so keep them away from raised beds. In addition, make sure no tools or other items are lying around the garden. Kids easily fall on sharp objects and become injured, so stay safe.

Step 4: Don’t Build over Water

If you live near a body of water like a pond or lake, you should build your raised bed about two feet higher than that area. This will help prevent any debris from falling into the water.

Step 5: Don’t Be Afraid to Ask Questions

It’s easy to follow instructions when you’re starting, but as you progress through your gardening career, you’ll need to ask questions. If you aren’t sure how to go about something, seek advice. You could also ask your local nursery or garden center for tips. They can usually point you in the right direction.

Step 6: Choose the Right Size

Once your raised bed is built, you’ll want to choose the size that works well for you. Smaller raised beds allow you to plant more closely together, while larger ones are good for sprawling veggies like pumpkins.

Frequently Asked Questions [FAQs]

1. What Is Raised Bed Gardening And Why Should I Consider Using This Method?

Raised bed gardening is a method that involves creating planting areas raised above ground level, typically using wooden frames or retaining walls. This technique has several benefits for gardeners, including improved soil drainage and aeration, better weed control, easier soil amendment, and reduced strain on the gardener’s back and knees.

2. How Do I Build A Raised Bed Garden?

To build a raised bed garden, choose a location that receives adequate sunlight (at least 6-8 hours per day) and is accessible for watering and maintenance. Determine your raised bed’s desired size and shape, then mark the area and remove any grass or weeds. Next, construct the frame using rot-resistant lumber, such as cedar or redwood, and secure the corners with screws or nails.

3. What Is The Best Soil Mixture For A Raised Bed Garden?

The ideal soil mixture for a raised bed garden is well-draining, rich in organic matter, and nutrient-dense. A good ratio is one-third compost, one-third topsoil, and one-third peat moss or coconut coir. Compost provides nutrients and improves soil fertility, while topsoil provides structure and drainage.

4. How Often Should I Water My Raised Bed Garden?

The frequency of watering your raised bed garden will depend on several factors, including the type of plants you are growing, the climate in your area, and the soil drainage of your raised bed. Generally, watering deeply and infrequently rather than shallowly and frequently is best. This encourages deep root growth and helps plants become more drought-tolerant.
