1. Does Zinc from Metal Raised Garden Beds Leach into Soil?
Galvanized steel is made by bonding a layer of zinc to the surface of the steel. This helps prevent the metal from rusting. One of the biggest concerns gardeners have with using metal raised garden beds is that the zinc used in the process can seep into the soil and damage any plants and vegetables growing in it. While small amounts of zinc may seep into the soil over a long period of time, that's not necessarily a bad thing for your vegetables or the people who eat them. Zinc is a natural mineral found in garden soil.
2. Metal raised flower beds can become too hot after drying
Metal conducts heat and is generally warm to the touch when exposed to sunlight. Do metal raised garden beds cause plants and soil to overheat? The answer is no. On warm days, soil temperatures near the edge of the garden may rise slightly, but not enough to have any effect on the plants. If you water your garden bed plants properly, you don't have to worry about them drying out. Like metal patio furniture or fencing, metal garden beds can get hot after prolonged exposure to the sun, but are still safe to touch and handle.
Do metal raised garden beds need to be filled with lots of soil?
One of the main advantages of raised garden beds is that you can choose the best soil type for a particular plant, rather than relying on the soil that is already in your yard or garden. However, beginner gardeners may be intimidated by the initial amount of soil required to set up a garden bed. Yes, garden beds do need soil, but they don't need it as much as you might think. Most plants and vegetables only need about a foot of good soil to grow. Instead of filling the entire garden bed with soil, use a filler like pine cones, packaged peanuts, or sand to cover the bottom half of the garden bed. Then, place a piece of landscape fabric on top of the fill and fill the top half with your favorite soil.
Do metal raised garden beds need a lot of water?
Raised garden beds are often large, and the thought of keeping the bed watered may seem daunting, but by following a few tips, you can keep the soil moist without having to water your garden bed regularly. When it comes to gardening, choosing the right soil is key, whether you're growing in the ground, pots, or garden beds. The best soil choice for raised garden beds is a light soil mix, which retains moisture so you don't have to water the bed as often.
5. The drainage performance of metal raised flower beds is not good
Metal raised garden beds do not drain well and your plants will drown in standing water. This is also not true. Being able to choose the right soil for your metal raised garden beds is a great benefit, as you can choose a light soil that drains easily. Additionally, many garden beds are either bottomless or have drainage holes that allow water to easily pass through the soil into the ground.
