Choosing the Best Materials for Raised Garden Beds ~ Homestead

Raised beds can provide superior protection from pests and weeds, offer comfortable ergonomics, and can be filled with ideal soil to grow food, flowers, herbs and more.This article will go over the most common (and not-so-common) materials used to make raised garden beds – including wood, metal, concrete, and more.We’ll discuss things to consider when choosing materials such as durability or safety, as well as the differences between various types of lumber.Finally, don’t miss the list of potential raised bed materials that we suggest to avoid for organic gardening.In addition to the list above, you could create a raised garden bed out of just about anything capable of holding soil and plants!After all, garden beds are subject to near-constant moisture, outdoor elements, and potentially insects or pests such as termites.If you opt to save money upfront and choose more affordable materials, you might be sacrificing the lifespan of your raised bed.For example, a planter box constructed of reclaimed pallets or soft pine wood likely won’t hold up half as long as one made with premium lumber.Likewise, large stones or concrete blocks will cost more than straw bales, but last a literal lifetime in comparison!Depending on your situation, you may be more than willing to give up a little lifespan to keep upfront costs down – especially if you’re renting your current home, or only setting up a temporary garden space.Heck, if you have easy access to large felled logs, it’s possible to create an incredibly durable AND affordable bed.For example, we are able to find great deals (and a larger variety of materials) for stones, blocks, gravel, bulk soil and mulch at our locally-owned landscape supply companies.My friend Katie (@frecklesandsprouts) created this rustic masterpiece from felled trees on her property.For instance, I would think twice before using painted or treated salvaged wood to create a garden bed for edible crops.The wood may be contaminated with toxic chemicals like lead, arsenic, or other heavy metals that can migrate (leach) into your soil and food.I’ve seen people use all kinds of up-cycled materials to make garden beds: like styrofoam coolers (made of polystyrene, a suspected carcinogen) or old car ties (contain benzene, polycyclic aromatic hydrocarbons, heavy metals, and a host of other substances that are toxic to human health).We’ve found that redwood is more affordable on the west coast, while cedar is more readily available and thus less expensive in the eastern US.Examples of long-lasting hardwood lumber include teak, maple, beech, hemlock, walnut, black locust, and oak.We built redwood raised beds around our patio, and attached trellises to the back to also double as chicken-proof fencing.Redwood and cedar definitely don’t require a protective sealer, but may benefit from it in climates with high humidity or precipitation.Cedar also gracefully ages with time, changing from reddish tan to silver grey (unless a sealer is routinely applied).That said, galvanized steel raised garden beds are a great choice for super wet climates!Even if the metal feels warm to the touch, damp soil does a great job of buffering temperature swings.Or, turn a prefabricated metal container into a raised garden bed – such as adding drainage holes to the bottom of a galvanized steel animal feed or water trough.My friend

interior, it is best to play it safe and replace them.Like those made from metal, raised garden beds constructed from concrete pavers, cinderblocks, or brick have the potential to be supremely durable
