Originating in France, the practice is popular raissed urban gardeners and small for profit farming operations. You can extend your growing season on the early and the late end by building a plastic tunnel over your bed to protect your plants from colder temps.

You raisee essentially build this setup right on top of it.

If possible, could you give me the measurements of the growing space and also how many blocks you used? Now I bury the first row raiseed blocks and have the 2nd row sitting above the soil with the flat blocks across the top.

Dear RangerMan, Thanks so much for the details of cinder block building — I have a question about gophers…do you put aviary wire on the bottom of the bed before the fill soil what size should a raised garden bed be keep gophers at bay or is it a concern.

Building a 4’x8’ Raised Bed Step-by-Step

First of all, you need to think of the place, quantity, size and the materials for your raised garden bed. An area with the most sun is best and more, small beds are good for a diverse garden. Most people use wood for the bed due to its natural feel and also because it’s cheap as well as durable. Here is a list of 42 DIY raised garden beds.

Raised beds are freestanding garden beds constructed above the natural terrain. Texas gardeners are discovering that raised bed gardens can help solve many problems. In many areas of the state the soil contains too much sand or clay, or is too alkaline for some plants to grow well. Soil that is poorly aerated because of compaction or poor drainage also may be a problem. Soil quality problems are often aggravated in urban and suburban settings, where topsoil and vegetation have been removed or the grade changed during construction.

Raised bed gardens improve growing conditions for plants by lifting their roots above poor soil. Soil in the beds can be amended to provide a better growing medium for plants, even plants that would not naturally thrive there. The soil in raised beds warms up earlier in the spring and is less apt to be invaded by certain grasses and by tree roots. Also, the height of raised beds may make them easier to maintain.

The first step in planning a raised bed is deciding where it will be located. Site selection and plant selection go hand in hand. Many vegetables, ornamentals and herbs require a lot of sunlight; a bed for these plants should be located where it will receive full sun.

If that is not possible, select a site that receives morning rather than afternoon sun. If only shady sites are available, try growing cool season vegetables that tolerate shade, such as broccoli, cabbage and lettuce. Also, some ornamental plants do best in partial shade. In windy regions, place beds where they are protected from prevailing winds by fences, buildings or other structures.

Beds should not be located in frost pockets or where air circulation is poor because fungal diseases often develop where there is little air flow.

A raised bed should drain well because soil that remains very wet will deprive plant roots of oxygen. Also, plant diseases develop more easily under wet conditions. Good drainage is especially important in vegetable beds. The soil and the location determine how well a raised bed will drain. If the bed contains clay soil, it should be amended with at least one third by volume of coarse sand, organic matter or a coarse grade of perlite to improve drainage. Do not locate a bed in a marshy area where it will sit in water.

Sometimes it is necessary to install special drains; determine this during the planning stage. Drain tiles or septic line tubing can be extended the length of the bed and through the walls at either end to create a drainage channel.

Normally, one line every 4 to 6 feet is sufficient. Another way is to dig a trench in the desired direction of water flow from the bed to a lower elevation , lay 3 to 4 inches of coarse stone in the trench, and then lay tiles or perforated tubing made of clay, concrete or plastic in the center of the trench. Cover the trench with more coarse stone and then soil. The French drain, another alternative, is simply a narrow trench filled with coarse stone leading from a poorly drained area to a lower elevation.

A raised bed should blend with its surroundings. A rectangular bed edged with a low brick wall, and filled with yaupon Ilex vomitoria or boxwood Buxus spp pruned into straight hedges or topiaries, has a formal look that might be appropriate in the front of a house.

An irregularly shaped perennial border tucked behind a dry stone wall is less formal, but could be attractive almost anywhere in the landscape.

A vegetable garden has an informal look that works best in private areas of the yard. The size of the bed should be kept in proportion to the space around it. A raised bed does not have to be very deep to be effective. Eight to 12 inches is usually adequate. If drainage is a problem, or if the plants you are growing prefer drier soil, the bed could be taller and filled with a porous growing medium.

Vegetable beds should be 12 to 18 inches deep. The material used to edge a raised bed should be stable, durable and attractive. It also establishes the outline of the bed and holds the soil in place. Edging may be as simple as metal strips, railroad ties or landscape timbers, or as intricate as a mortared brick or stone. A crested bed is one in which the soil is simply mounded from the edges of the bed to the center; it may or may not have an edging.

Metal edging comes in 8- to foot lengths, is easy to install, and is convenient for edging curved beds. However, it can rust with time, and unless plantings overflow the bed or the edging is camouflaged with a more aesthetic material, it may not be as attractive as you would like. Ties and timbers can be laid singly or in layers and have a rustic appearance.

Railroad ties treated with creosote do not appear to pose any health problems because most of the creosote has leached away. There is some controversy about using treated landscape timbers, but studies have shown that any compounds that leach out are well within safe levels established by the EPA, both in growing media and in harvested produce.

If you are concerned about using treated timbers, line the inside of the bed walls with polyethylene, roofing felt or similar materials to form a protective barrier.

Stone walls make interesting beds, and can be constructed with cracks and openings for creative plantings. However, stone can be expensive. Interlocking pavers are increasingly popular and are easier to install than mortared stone. Whichever edging material you choose, it should be strong enough to hold the growing media and withstand being bumped into or ridden over by a riding lawn mower. It should be installed properly and complement the rest of the landscape.

The design phase is the best time to decide how you will irrigate your raised bed. Hand watering may be simplest in many cases, but it can become tedious; the gardener must also know when and how much to water or plants will suffer.

With an automated sprinkler system beds can be watered regularly with little effort, but this method will wet the foliage, which contributes to disease and salt damage. If the system is automatically timed it may come on whether or not there has been recent rainfall, and thus waste water.

So, an automated system may be the most convenient for the gardener, but it is not necessarily best for the plants. Pop-up or stationary risers are prone to evaporation and drift during windy conditions. Low-flow systems can be more efficient under warm, windy conditions.

Low-flow irrigation systems that work well for woody plants and vegetables include microsprinkler, drip, trickle and soaker hose systems. These systems conserve water, can be installed under mulch, can be regulated to flow at rates individual plants need, and are less likely to wet foliage. However, they do have some disadvantages. Emitters are prone to clogging unless the water used is very clean, and if emitters are installed under mulch it is difficult to spot problems.

Emitters are also sensitive to elevation changes along the irrigation line and require pressure compensating lines. Finally, rodents and other wildlife can easily damage some drip lines.

If you choose a sprinkler system, decide how many sprinkler heads you will need and whether sprinkler heads will pop up or be set on risers. Be sure to consider the spray overlap, angle of spray and height of the sprinkler heads. Always design the system so that at least one additional riser per section can be added later.

You may need this flexibility as your plantings mature. If you choose drip or trickle irrigation, determine the length of the hose and the number of emitters you will need. Drip tape with inch emitter spacing is best for vegetables. Beds should be divided into watering zones according to the plants needs, the size of the system, the available water pressure, and the volume of water flow available.

Zone watering can be manual or timed. No single irrigation system is appropriate for all raised beds. Sometimes a combination of systems works best. If the bed has straight lines, use stakes and string to outline the perimeter. Garden hose or rope works well for outlining curved beds. Most vegetable beds are square or rectangular so that vegetables can be planted in rows. Many ornamental beds are curved. To make maintenance easier, particularly mowing, design the bed with long, flowing curves rather than many tight ones.

Remove any woody plants with loppers, hand saws or chainsaws, and then dig out the roots. Apply a systemic herbicide to kill perennial weeds and prevent them from returning. Or, kill vegetation without herbicide by covering the bed area with clear plastic anchor edges with rocks or soil for 1 to 2 months. If both day and night temperatures are warm, the heat generated under the plastic will kill plants, though not as quickly as herbicides.

Once the site is clear of vegetation, you must till the soil thoroughly. Metal edging is usually a 4- to 6-inch wide metal strip in varying lengths. They are connected by stakes that are inserted through overlapping notches.

Place the strips on edge along the perimeter of the bed and overlap the ends, lining up the notches. Hammer the stakes into the soil through the overlapping notches. Using a rubber mallet or a piece of wood between a hammer and the top of the edging, lightly hammer the edging into the soil between the stakes.

It is best to partially sink the stakes until all are in place, and then sink them to the desired depth. If the soil is hard and dry, use water to soften it, or excavate the soil to accommodate the edging. To build a brick-edged raised bed, first pour a concrete footer at least 6 to 12 inches high and 16 to 18 inches wide. This will be the base of the wall. Dig the trench for the footer carefully so that you will not need to use forms.

Smooth the top of the footer with a trowel. Rap the brick gently with the trowel handle to set it and remove the excess mortar squeezed from between the bricks.

Continue until the edging is complete.
