What To Look For In Soil For Raised Beds
Since raised garden beds are separated entirely from the soil in the ground, it is the gardener’s job to create a suitable growing environment for the plants. There are several things that can help create the perfect soil.
To begin with, it is essential to know what you intend to grow in a particular garden bed. Each plant will flourish in certain conditions better than others. For instance, some plants will thrive better in soil that is more acidic while others require a pH level that is more basic. More importantly, it should be noted that their distinct needs require them to be planted separately and will benefit immensely from being planted with the correct soil blend.
The Simple Blend
Gardeners who are planning on filling up several large raised beds should consider simple blends. This is great for the gardener, who has access to plenty of robust loam. Make sure to screen the topsoil or purchase topsoil that is already screened, get equal parts of compost that have been screened as well, mix together thoroughly. To avoid the growth of grass contamination and weed, gardeners can opt to discard the soil’s top layer. Look for compost you can buy in bulk, make sure to only source for clean composts (kitchen, manure, mushroom, and fish). Fill up the beds with the basic mix and more compost annually, this should be done early springtime.
The Luxury Blend
Individuals with smaller container gardens or those who simply want to go all out and start their raised garden beds weed-free, can opt to go with purchased supplies that start from scratch approach. It is possible for plants to flourish with a mixture of 1/3 peat moss, 1/3 vermiculite, and 1/3 composts, this non traditional garden variety perfectly resembles soil. For larger raised planter beds, gardeners can simply adjust each component into a quarter peat, a quarter vermiculite, with the remainder being composted. In place of vermiculite, coconut coir or perlite can be used – these mediums are particularly important for providing aeration and water retention especially in containers that can create moisture and compaction problems.
The Lasagna Method
Gardeners building raised beds that are extra tall or those with a good sized lawn would benefit from having beds that are waist high. The trick is to fill the raised bed with quality soil. Of course, most superior grade soil can be pricey so the next best thing to do is to layer your bed with grass clippings and leaves. Both are great organic bulk materials which are perfect for layering the lower regions of the tall beds, this allows them to slowly compost creating rich soil over time. To prevent matting, gardeners should make the grass clippings in thin layers. Add a compostable barrier once the beds are 6-12 inches close to the top. To prevent the soil from quickly sifting down, use untreated cardboard, and then add your choice of soil mix to fill the remainder of the bed.
Weather is another factor to consider when selecting the best garden soil mix. Areas that are generally dry year round will require the use of soil that is able to retain moisture well. On the other hand, areas that experience a good amount of rainfall will benefit from raised garden beds that have a good drainage system. Thus, the soil to be used for raised garden beds will depend on where you live and what you wish to grow. Because you are “building” your soil from scratch, so it is important to have the right blend to get your plants to thrive and flourish.
What to Plant
Now that you have the basics figured out and you have your raised bed set up, it’s time to pick the plants that you want to grow. For the most part, many raised beds are filled with vegetables, though there are some that do contain flowering plants and shrubs. For this purpose, we will be listing down vegetables that any newbie can grow in their raised beds.
Bush beans — this foolproof veg easily goes from seed to harvest in one to two months tops. Best planted after the chilly frosty months since these beans are huge fans of warm weather and warm soil.
Cherry tomatoes — tomatoes are permanent fixture in any garden with a vegetable patch. Large varieties tend to take longer to grow so an ideal option is to go for cherry tomatoes. These juicy fruits start producing two months from the seedling transplant. To get the best soil for tomatoes, first time gardeners can stick to the potting soil used by the garden center where the seedlings are originally from.
Peas — the best time to sow pea seeds is in the early spring time. Four to six weeks before the last expected frost is the ideal time to start loosening and enriching the soil in preparation for the peas. Whether it be sugar snap, snow peas, or shell peas, growing them is easy as long as you sow the seeds about two inches apart from each other in double rows that are spaced six inches away. When growing a variety that requires staking, consider adding a hang netting or trellis.
Cucumbers — just like tomatoes, cucumbers are pretty much a staple especially for those who just love the refreshing crunch, a freshly picked, one can offer on a hot summer day. Another veggie that favors the warmer season, all it takes is to seed them directly into the raised garden bed. Seedlings are also easily found in nurseries if you want to speed up the process a little. Water consistently, and ply them with lots of compost and you will get the best cucumber harvest.
Garlic — not a plant that you can just plant and forget, garlic does require some bit of patience to grow. Diseases and pets are also drawn to it, but with the best fungicide and the best organic fertilizer your garlic should grow just fine. To keep the moisture in, don’t forget to mulch the beds with straw, doing so also helps reduce the growth of weeds drastically.
Leaf lettuce — another fast and easy veggie to grow in your garden, leaf lettuce can already be harvested when the baby greens are about two to four inches in length. To harvest, simply clip the leaves working from the outside, leaving the center, which will continue to grow. Simply harvest once leaves have sprouted to the ideal size.
What is the advantage of raised garden beds?
There are numerous advantages to raised garden beds especially when it comes to growing vegetables. In an urban landscape where spaces are relatively small, beds allow gardeners to produce larger harvests.
Raised beds are also great for growing plants because the soil has not been walked on or compressed. The soil then remains light, well aerated and permits better root growth.
It has also been observed that raised beds have improved drainage systems. This improves drainage as well as the tinder sidings that are exposed to the sun also results in beds that warm up quicker in the springtime, allowing for crops to start earlier than usual.
What is the depth of a raised garden bed?
The depth or height of your raised garden bed will actually depend on your personal preference as well as your planting needs. For the most part, many gardeners opt for raised beds ranging between 6 inches and 24 inches. As a general rule of thumb, it is crucial to note that you will have to fill the depth you choose with soil. Therefore, it can be laborious and not to mention expensive to fill up very deep beds. Raised beds that sit directly onto of soil can be shallower since the roots are able to grow deeper into the soil.
Does the bottom of the bed need to be lined?
There are two major reasons why gardeners line their beds. The first is to discourage the growth of weeds. Next is to act as a barrier against ground animals that may pop up from under the raised beds to eat your crop. When it comes to weeds, it should be said that most of the weeds that need to be dealt with will grow top level as a result of birds dropping it down. In case, you are still concerned of aggressive weeds sprouting from deep below, you can line the bed with cardboard. It’s a great barrier that keeps out weeds while encouraging earthworm presence and is added nutrients to the soil once it breaks down.
How much maintenance is needed?
A finished raised bed requires very minimal maintenance. Most of the heavy lifting is done in prepping and putting together the bed. At the most, gardeners will spend most of the maintenance pulling out weeds every now and then. A good amount of mulch ensures a fertile and improved soil structure while smothering the weeds in the process.
Like many things in life, patience is a much needed virtue when it comes to gardening. It is essential to have a clear understanding of what the soil needs, as the gardener you can easily add to it or take away things in order to create the best soil for raised beds. Making the effort to learn the right soil blends, the crops to plant, correct timing needed to sow the beds, and even learning some preventive measures to keep the beds disease and pest free is part of the journey of every gardener.
Though it may take some trial and error to fully understand how your garden works, once you successfully master it you will reap the rewards of a bountiful harvest or a flourishing floral wonderland. And unlike planting directly onto the ground, raised garden beds produce results that will prove satisfactory to even the most amateur gardener.
