Your Guide to Raised and Container Gardening!

Below is hopefully an amazing resource for you in your journey through Raised Beds and Container Gardening! Let me know if this helps you or if there is a better way. I'm always wanting to learn new and exciting ways to grow in raised and container gardens!

Planning & Location

Track the Sunlight:

Utilize Partial Shade:

Utilize Partial Shade:

 Ensure your raised bed or containers get 6 to 8 hours of direct sunlight daily for heavy-fruiting crops like tomatoes and peppers. 

Utilize Partial Shade:

Utilize Partial Shade:

Utilize Partial Shade:

 Reserve shadier spots for leafy greens (lettuce, spinach) and herbs, which will actually bolt less quickly in cooler conditions.  

Proximity to Water:

Utilize Partial Shade:

North-to-South Orientation:

 Always place your garden near a water source. Hauling heavy watering cans across a yard gets old very quickly.

North-to-South Orientation:

North-to-South Orientation:

North-to-South Orientation:

 Align long raised beds from north to south so all plants get equal sun exposure throughout the day without blocking one another.

Avoid Low Spots:

North-to-South Orientation:

Avoid Low Spots:

Don't place raised beds in naturally swampy or poorly drained areas of your yard.

Mind the Wind:

North-to-South Orientation:

Avoid Low Spots:

 Protect tall container plants from high winds by placing them near a wall, fence, or sturdy lattice structure.

Accessibility Height:

Accessibility Height:

Accessibility Height:

 Choose a bed height that fits your body. Raised beds 18 to 27 inches tall are ideal for comfortable, bend-free gardening.

Map Your Walkways:

Accessibility Height:

Accessibility Height:

 Leave 3 to 4 feet of space between raised beds to comfortably fit a wheelbarrow or lawnmower.

Leverage Patios:

Accessibility Height:

Leverage Patios:

Concrete and brick patios absorb heat during the day and radiate it back at night, creating an excellent microclimate for heat-loving crops.

Start Small:

Start Small:

Leverage Patios:

 If you're a beginner, start with one 4x4 foot bed or 3 to 4 medium containers to master the basics without feeling overwhelmed.

Materials & Construction

The 4-Foot Width Rule:

The 4-Foot Width Rule:

The 4-Foot Width Rule:

 Never build a raised bed wider than 4 feet. This ensures you can easily reach the center from either side without stepping on the soil. 

Safe Wood Choices:

The 4-Foot Width Rule:

The 4-Foot Width Rule:

 Use naturally rot-resistant woods like cedar, redwood, or black locust. Avoid older, chemically treated lumber.

Line the Bottom:

The 4-Foot Width Rule:

Gopher and Mole Defense:

 Lay down a thick layer of cardboard or newspaper at the bottom of a new raised bed to smother grass and weeds naturally.

Gopher and Mole Defense:

Gopher and Mole Defense:

Gopher and Mole Defense:

  Staple hardware cloth (wire mesh) to the bottom of your raised bed frame before filling it to block burrowing pests.

Corner Reinforcements:

Gopher and Mole Defense:

Corner Reinforcements:

 Use sturdy wood corner blocks or metal brackets to prevent your bed corners from bowing out under intense soil weight.

Support Long Boards:

Gopher and Mole Defense:

Corner Reinforcements:

Keep side boards under 6 feet, or insert middle stakes to prevent the wood from bowing outward over time.

Fabric Grow Bags:

Cinder Block Quick-Beds:

Hügelkultur Filler:

Use heavy-duty fabric grow bags for a cheap, breathable, and portable raised-bed alternative.

Hügelkultur Filler:

Cinder Block Quick-Beds:

Hügelkultur Filler:

For deep beds (over 18 inches), fill the bottom half with rotting logs, sticks, and dry leaves to save money on premium soil.

Cinder Block Quick-Beds:

Cinder Block Quick-Beds:

Cinder Block Quick-Beds:

Stack cinder blocks for a fast, tool-free raised bed, and use the open holes to plant small herbs or flowers.

Soil & Potting Mix Secrets

Never Use Regular Dirt in Pots:

Lightweight Mixes for Elevators:

Never Use Regular Dirt in Pots:

In-ground yard dirt is too dense and will compact inside containers, ultimately suffocating plant roots.

The Ideal Raised Bed Recipe:

Lightweight Mixes for Elevators:

Never Use Regular Dirt in Pots:

Mix 50% to 60% high-quality topsoil with 40% to 50% nutrient-dense organic compost.

Lightweight Mixes for Elevators:

Lightweight Mixes for Elevators:

Lightweight Mixes for Elevators:

For waist-high elevated beds on legs, use a lighter potting mix base rather than heavy topsoil to protect the structure.

Perlite for Aeration:

The Annual Compost Refresh:

Lightweight Mixes for Elevators:

   Mix perlite or vermiculite into your container soil to improve drainage and keep the texture fluffy.

Coconut Coir for Moisture:

The Annual Compost Refresh:

The Annual Compost Refresh:

 Swap peat moss for coconut coir to help your container mixes hold water sustainably without altering soil pH.

The Annual Compost Refresh:

The Annual Compost Refresh:

The Annual Compost Refresh:

Top off your raised beds with 2 to 3 inches of fresh compost every spring to replenish lost nutrients.

Avoid Excessive Manure:

Avoid Excessive Manure:

Avoid Excessive Manure:

Composted manure is great but very high in phosphorus; use it sparingly to avoid severe nutrient imbalances.

Test, Don’t Guess:

Avoid Excessive Manure:

Avoid Excessive Manure:

 Do a basic soil test every 2 to 3 years to see exactly what nutrients your raised bed is missing.

Attract Native Worms:

Avoid Excessive Manure:

Attract Native Worms:

Keep a little native soil at the bottom interface of your raised bed so earthworms migrate up to aerate your soil.

Avoid Over-Tilling:

Avoid Over-Tilling:

Attract Native Worms:

Don’t flip or till your raised bed soil every year. This preserves the beneficial fungal networks (mycorrhizae) beneath the surface.

Watering Strategies

Drip Irrigation Over Head-Watering:

Drip Irrigation Over Head-Watering:

Drip Irrigation Over Head-Watering:

Install a simple drip irrigation or soaker hose system to deliver water directly to the roots and minimize evaporation.

The Two-Inch Finger Test:

Drip Irrigation Over Head-Watering:

Drip Irrigation Over Head-Watering:

Stick your finger two inches deep into the soil. If it feels completely dry, it's time to water.

Water Early in the Morning:

Drip Irrigation Over Head-Watering:

Water Early in the Morning:

Watering early gives leaves time to dry off during the day, significantly cutting down on fungal diseases.

Deep and Infrequent Wins:

Double-Watering Containers:

Water Early in the Morning:

Water deeply and less often rather than giving your plants quick daily sprinkles. This encourages massive, deep root systems.

Double-Watering Containers:

Double-Watering Containers:

Double-Watering Containers:

Water your pots until it runs out the bottom, wait five minutes, and water lightly again to ensure the root ball is thoroughly soaked.

Self-Watering Pots:

Double-Watering Containers:

Double-Watering Containers:

Use containers with built-in bottom reservoirs for notoriously thirsty plants like tomatoes and cucumbers. 

Mulch Everything:

Beware of Black Plastic:

Beware of Black Plastic:

Add a 2-inch layer of clean straw, shredded leaves, or wood chips to lock in moisture and regulate soil temperatures. There are so many options to choose from!

Beware of Black Plastic:

Beware of Black Plastic:

Beware of Black Plastic:

Dark plastic containers absorb intense solar heat, causing the soil inside to dry out incredibly fast.

Empty the Saucers:

Beware of Black Plastic:

Empty the Saucers:

Dump standing water out of your container saucers 30 minutes after watering to prevent root rot.

Harvest Rainwater:

Harvest Rainwater:

Empty the Saucers:

Hook up a rain barrel to your house gutters for a free, chlorine-free source of pure water.

Fertilization & Plant Nutrition

Slow-Release Granules:

Nitrogen for Leafy Greens:

Liquid Feeding for Pots:

Mix a slow-release organic fertilizer into your potting soil right at planting time for steady, long-term feeding.

Liquid Feeding for Pots:

Nitrogen for Leafy Greens:

Liquid Feeding for Pots:

Because nutrients wash out of containers with every heavy watering, feed potted plants with a diluted liquid fertilizer every two weeks.

Nitrogen for Leafy Greens:

Nitrogen for Leafy Greens:

Nitrogen for Leafy Greens:

Use blood meal or fish emulsion to give kale, spinach, and herbs a rapid boost of vegetative growth.

Phosphorus for Blooms:

Calcium Boost for Tomatoes:

Nitrogen for Leafy Greens:

 Mix bone meal into the soil when planting tomatoes or flowers to encourage heavy blooming and root development. 

Calcium Boost for Tomatoes:

Calcium Boost for Tomatoes:

Calcium Boost for Tomatoes:

Add crushed eggshells or agricultural gypsum to your soil to prevent blossom end rot in tomatoes and peppers.

Epsom Salt Trick:

Calcium Boost for Tomatoes:

Calcium Boost for Tomatoes:

A light spray of magnesium sulfate (Epsom salt) dissolved in water can rapidly green up yellowing, magnesium-deficient leaves.

Compost Tea:

Don't Over-Fertilize:

Don't Over-Fertilize:

 Soak compost in a bucket of water for 24 to 48 hours to brew a potent, microbe-rich liquid fertilizer. 

Don't Over-Fertilize:

Don't Over-Fertilize:

Don't Over-Fertilize:

Too much fertilizer can burn delicate roots and attract massive pest colonies who love overly lush, tender growth.

Flush the Soil:

Don't Over-Fertilize:

Group by pH Needs:

Every few weeks, water your containers thoroughly with pure water (no fertilizer) to flush out toxic salt build-ups. 

Group by pH Needs:

 For beautiful ornamental pots, plant a tall focal point (thriller), mid-size leafy plants (filler), and trailing vines (spiller).

Square Foot Gardening:

Thriller, Filler, Spiller:

Square Foot Gardening:

Divide your raised bed into a 1x1 foot grid system to precisely manage plant spacing and maximize every inch.

Intensive Planting:

Intercropping Tactics:

Square Foot Gardening:

Space plants so their leaves just barely touch at maturity, creating a "living mulch" that blocks sunlight from weed seeds.

Succession Planting:

Intercropping Tactics:

Intercropping Tactics:

Replant empty spaces every 2 to 3 weeks with quick crops like radishes or green salad mixes for a continuous harvest.

Intercropping Tactics:

Intercropping Tactics:
