How to Properly Sow Seeds in Metal Raised Garden Beds?

Sowing seeds in metal raised garden beds is just as simple as sowing them in regular garden beds. The difference lies in how you prepare the bed before planting. Let's take a detailed look at how you can start sowing seeds in metal raised beds.


First, remove weeds and debris from the area where you intend to sow seeds. You don't want to damage the seedlings when you dig out the weeds accidentally. Also, ensure that the soil is loose enough so the roots won't stick together.
Next, mix a small amount of fertilizer or organic matter into the soil. If you use fertilizers, make sure to follow the instructions provided by the manufacturer. Organic matter such as manure, compost, or peat moss works very well.
If you decide to use organic matter, make sure to apply it evenly throughout the entire bed. Otherwise, you might damage the plants' roots due to the uneven distribution of nutrients.
Finally, you need to rake the surface of the bed flat. Raking helps prevent the seeds from sticking together. Also, raking allows air to circulate through the roots.


Now that you're ready to sow seeds soak them overnight in warm water and drain excess water. You can use a seed tray to distribute seeds across the prepared bed evenly.
Once sown, cover the seeds with about 1/4 inch of soil and gently press the ground around each seed. This prevents the seeds from drying out and also keeps the soil moist.
You can also sprinkle seeds directly onto the soil. However, if you do this, make sure not to let the seeds touch each other. Instead, space them apart. Otherwise, they may have poor germination rates.


When sowing seeds in metal raised beds, you should be careful not to damage the young seedlings. You can protect your seedlings using a mesh screen. Alternatively, you can place plastic sheeting over the raised bed.
Also, keep an eye on the weather conditions during the first week after planting. Rainfall can cause the seeds to rot. So, avoid watering the raised bed until the sun has dried up the soil.
In other words, wait for the soil to dry before watering the bed. You can mist the bed with water if you see signs of dampness. But, make sure to do this sparingly. Too much moisture can lead to root rot. You should also look closely at signs of any pests infesting the bed.

If you find any bugs, spray insecticide on the affected areas. Organic pesticides are safe for both humans and animals.


Metal raised gardening beds allow you to grow healthy crops even in cold climates. They also provide a convenient way to raise vegetable gardens. However, there are some things you need to consider before starting to plant seeds in metal-raised gardens.
First, you need to know what seeds you'll be growing. Then, you need to prepare the garden bed properly. Finally, you need to take precautions against possible problems. If you do all these things correctly, you'll enjoy the successful results of your efforts.
