S23 E22: Urban Gardens, Apron Driveway

S23 E22: Urban Gardens, Apron Driveway is the kind of Ask This Old House episode that proves home improvement is not just about bigger kitchens, shinier bathrooms, and garages so organized they make your sock drawer feel judged. This episode brings together two projects that look small at first glance but carry big lessons: creating greener urban garden spaces and replacing a tired driveway apron with handsome cobblestones.

On one side, landscape contractor Jenn Nawada travels to Detroit, Michigan, where pollinator-friendly planting is helping turn city lots and small yards into living ecosystems. On the other side, masonry expert Mark McCullough tackles a brick driveway apron that has seen better days and replaces it with a durable, classic cobblestone entrance. Tom Silva also steps in with a quick, useful breakdown of impact drivers and power drills, because no This Old House project is complete without at least one tool conversation that makes you reconsider everything in your garage.

The beauty of this episode is its balance. It is part garden inspiration, part hardscape tutorial, and part reminder that a home’s exterior works best when nature and structure stop arguing and start cooperating.

What Happens in S23 E22: Urban Gardens, Apron Driveway?

The episode follows three practical themes. First, Jenn explores urban pollinator gardens in Detroit, a city with deep industrial roots and a growing reputation for community-led green spaces. She meets with a local nonprofit connected to Detroit’s pollinator movement and discusses how native plants can support bees, butterflies, and other beneficial insects.

Second, Jenn helps a couple begin an elevated herb garden bed. This project is friendly to beginners because it does not require a giant backyard, a tractor, or the spiritual patience of a monk. An elevated bed can fit into a compact urban yard, patio, or sunny corner, while making planting, watering, and harvesting much easier on the back.

Third, Mark helps remove an old brick driveway apron and install cobblestones. A driveway apron is the transition area where the driveway meets the street. It takes abuse from tires, rain, snow, road grit, and the occasional delivery driver who treats the curb like a suggestion. When built correctly, a cobblestone apron improves both durability and curb appeal.

Why Urban Gardens Matter More Than Ever

Urban gardens are not just “nice little patches of flowers.” They can be practical, ecological, and social. In dense neighborhoods, green spaces help soften hard surfaces, create habitat, improve soil awareness, and give residents a place to grow food, herbs, flowers, and community pride.

Detroit is a fitting backdrop for this story. The city has a long history of reinvention, and urban gardening is one of the most visible ways neighborhoods can reclaim underused land. Pollinator gardens, in particular, can transform vacant lots, front yards, school gardens, and community spaces into tiny biological airports where bees and butterflies refuel.

Pollinator Gardens: Small Space, Big Impact

A pollinator garden is designed to provide food and habitat for pollinating insects and wildlife. The best versions are not random flower explosions. They are planned with intention: native plants, staggered bloom times, minimal pesticide use, and enough plant diversity to keep pollinators fed from spring through fall.

Native plants are especially valuable because they are adapted to local climate, soil conditions, and local pollinators. In the Midwest, a pollinator-friendly garden might include plants such as milkweed, purple coneflower, black-eyed Susan, bee balm, asters, goldenrod, little bluestem, and other regionally appropriate species. The exact plant list should always match the local growing zone and site conditions.

The trick is to plant in groups rather than scattering one lonely flower here and another over there like botanical confetti. Pollinators find clumps of flowers more easily. A generous cluster of blooms is basically a neon diner sign for bees: “Nectar served here.”

Soil Preparation: The Unsung Hero of Urban Gardening

Beautiful gardens begin below the surface. In urban settings, soil can be compacted, low in organic matter, poorly drained, or potentially contaminated from previous land use. Before planting food crops directly in the ground, gardeners should consider testing the soil, especially in older neighborhoods or lots near roads, former buildings, or industrial areas.

Raised beds and elevated beds are popular solutions because they allow gardeners to control the growing medium. Instead of fighting mystery soil, you can fill the bed with a balanced mix of quality topsoil and plant-based compost. A good raised-bed mix should hold moisture without turning into soup, drain well without drying out instantly, and provide enough organic matter to support healthy roots.

One common mistake is assuming that more compost automatically means better soil. Compost is wonderful, but too much can create water and nutrient imbalances. Think of compost like hot sauce: the right amount improves everything; too much makes the whole situation dramatic.

Elevated Herb Beds: Practical, Pretty, and Dinner-Friendly

The elevated herb garden in this episode is one of the most approachable takeaways for homeowners and renters. Herbs do not demand a football field. Many thrive in containers, raised planters, and small beds as long as they get enough sun and drainage.

For a sunny elevated herb bed, consider culinary favorites like basil, parsley, chives, thyme, oregano, rosemary, sage, dill, and mint. However, mint should usually be kept in its own container unless you want it to launch a hostile takeover. Mint is delicious, fragrant, and apparently convinced it owns the deed to your property.

Herbs generally prefer consistent watering, but many Mediterranean herbs dislike soggy roots. Rosemary, thyme, oregano, and sage prefer a well-drained mix. Basil and parsley appreciate more regular moisture. Grouping herbs with similar water needs can make maintenance easier and reduce plant drama.

Planting Techniques That Actually Work

Good planting technique is simple but important. Start by placing the plants on top of the soil while they are still in their nursery pots. This gives you a chance to adjust spacing and visual balance before committing. Taller plants usually work best toward the back or center, depending on whether the bed is viewed from one side or all sides.

When planting, dig a hole slightly wider than the root ball. Gently loosen circling roots if the plant is root-bound. Set the plant at the same depth it was growing in the pot, then backfill and firm the soil lightly. Water thoroughly after planting to settle soil around the roots.

Mulch can help conserve moisture and reduce weeds, but do not bury the plant crowns. A thin layer of shredded leaves, straw, or fine bark can work well. In pollinator gardens, avoid over-mulching every inch of soil because some native bees nest in the ground and need access to bare or lightly covered soil.

Maintenance: The Difference Between Garden and Jungle

Urban gardens do not need to look wild to be wildlife-friendly. A successful pollinator garden can have clean edges, repeated plant groupings, defined paths, and seasonal structure. Those design choices help neighbors understand that the garden is intentional, not simply a lawn that escaped supervision.

Maintenance should include watering during establishment, removing invasive weeds, cutting back plants at appropriate times, and replacing failed plants with better-suited varieties. For pollinator support, consider leaving some stems and leaf litter through winter, since many beneficial insects overwinter in plant material. The garden may look slightly less “magazine perfect,” but the bees will not leave a bad review.

The Driveway Apron: Small Area, Serious Job

Now, from flowers to physics. The driveway apron may not be glamorous, but it works hard. It is the section that bridges private driveway and public street. Because it sits at the edge of traffic, drainage, and municipal rules, it needs careful planning.

In the episode, Mark McCullough removes a brick apron and replaces it with cobblestones. This is a smart upgrade when the existing apron is uneven, loose, cracked, or visually out of step with the home. Cobblestones provide a classic look and can handle heavy use when installed over a properly prepared base.

Before anyone grabs a saw or starts removing bricks, there is one important step: check local rules. In many communities, the driveway apron falls partly or entirely within the public right-of-way. That means permits, material standards, slope requirements, sidewalk transitions, and inspections may apply. Ignoring that step can turn a weekend project into a paperwork casserole.

Why Cobblestones Work Well for an Apron

Cobblestones are durable, attractive, and visually distinct. They create a clear threshold between the street and the driveway, almost like a welcome mat for your car. They can also help strengthen the driveway edge, especially when installed with proper restraint and a compacted base.

Compared with plain asphalt or concrete, cobblestones add texture and character. They are particularly effective on traditional homes, older houses, cottages, and properties where the driveway needs a little architectural dignity. Basically, cobblestones are the difference between “there is the driveway” and “ah yes, the entrance.” Very fancy. Slightly British. Still practical.

How a Driveway Apron Replacement Typically Works

While every site is different, the general process begins with measuring and marking the apron area. The old material is removed carefully, whether it is brick, asphalt, or concrete. The base is then excavated to the proper depth, allowing room for compacted aggregate, bedding material, and the cobblestones themselves.

Base preparation is the most important part of the job. If the base is weak, uneven, or poorly compacted, the finished apron may shift, sink, or collect water. A proper base helps distribute vehicle loads and keeps the cobblestones stable through weather cycles.

After the base is prepared, bedding sand or another specified setting bed is spread evenly. The cobblestones are placed in the chosen pattern, adjusted for alignment, and cut where needed at edges. Joints may be filled with stone dust, sand, polymeric sand, or mortar depending on the system and local conditions. Edge restraint is critical so the stones do not creep outward over time.

Drainage Matters

Driveway aprons must manage water correctly. The surface should slope in a way that moves water away from the garage, avoids puddles, and does not create problems for sidewalks, streets, or neighboring properties. Drainage is one reason municipal standards matter so much. A beautiful apron that sends rainwater into the wrong place is not charming; it is just a wet apology waiting to happen.

Power Drills vs. Impact Drivers: Tom Silva’s Useful Tool Moment

Tom Silva’s tool segment fits neatly into the episode because both gardening and hardscaping depend on using the right tool for the job. A power drill is ideal for drilling holes and driving screws with control. An impact driver delivers more rotational force and is especially useful for driving long screws or fasteners into dense material.

For beginners, the easiest way to remember the difference is this: the drill is the versatile all-rounder; the impact driver is the compact muscle. The drill says, “Let’s be precise.” The impact driver says, “I brought torque.” Both are useful, but they are not identical.

How the Two Projects Connect

At first, urban gardens and driveway aprons seem unrelated. One is soft, green, and buzzing with life. The other is stone, base material, and compaction. But both are really about improving the edges of a property.

An urban garden improves the ecological edge between home and neighborhood. It invites pollinators, softens hardscapes, and makes outdoor space feel alive. A cobblestone apron improves the physical edge between driveway and street. It makes the entrance stronger, cleaner, and more finished.

Together, they show that curb appeal is not only about looking good in a real estate photo. It is about function, stewardship, and daily use. A front yard with native flowers and a well-built apron says, “This home is cared for.” It also says, “We understand drainage,” which is less poetic but very important.

Design Ideas Inspired by S23 E22

Homeowners can borrow several ideas from this episode without copying the projects exactly. A narrow strip beside a driveway can become a pollinator border with compact native perennials. A sunny patio can hold an elevated herb planter. A cracked apron can be replaced with cobbles, concrete pavers, or another code-approved material that suits the home.

For a cohesive look, repeat materials and colors. If your home has warm brick, choose stone or pavers that complement it. If your garden has a natural meadow style, keep the hardscape simple. If your driveway apron is visually bold, let nearby planting soften the edges with grasses, flowering perennials, and low shrubs.

Common Mistakes to Avoid

In the garden, the biggest mistakes are skipping soil preparation, choosing plants unsuited to the site, planting too closely, and using pesticides that harm beneficial insects. Another mistake is installing a garden and then forgetting that plants need water during their first season. Native plants are resilient, not magical. They still appreciate a drink while establishing roots.

With driveway aprons, common mistakes include ignoring permits, underbuilding the base, failing to compact layers properly, forgetting edge restraint, and creating poor drainage. A driveway apron is not the place to “eyeball it” unless your eyeballs come with municipal engineering credentials.

Budget and Planning Tips

For urban gardens, start small. A well-maintained 4-by-8-foot bed is better than a giant neglected plot that becomes a weed documentary. Buy younger plants, divide perennials over time, and use mulch wisely. Community plant sales, native plant nurseries, and local extension resources can help reduce cost and improve plant selection.

For an apron project, budget for demolition, disposal, base material, bedding material, stones, edge restraints, tools, rental equipment, and permit fees. It is also smart to keep a contingency fund. Outdoor projects have a way of revealing surprises, usually right after the hardware store closes.

Real-World Experience: Lessons from Urban Gardens and Driveway Aprons

The most useful lesson from S23 E22: Urban Gardens, Apron Driveway is that outdoor improvements succeed when you respect the site. That sounds simple, but it is the part many people rush past. A garden is not just a shopping cart full of pretty plants. A driveway apron is not just stones arranged in a charming pattern. Both projects need observation before action.

In an urban garden, the first experience many beginners have is surprise. The sunniest spot may not be where they hoped. The soil may be heavier than expected. The wind may whip around a building corner. A downspout may flood one bed while another dries out like toast. Spending a few days watching light, water, and foot traffic can save months of frustration.

Another practical experience is learning that small gardens are more forgiving than large ones. An elevated herb bed can teach almost everything a beginner needs: watering rhythm, harvesting, pruning, soil settling, pest observation, and seasonal replanting. Herbs are especially rewarding because the harvest is immediate. Snip basil for pasta, thyme for roasted vegetables, or chives for eggs, and suddenly the garden feels less like a chore and more like a tiny outdoor grocery store with better lighting.

Pollinator gardens teach patience. The first year often looks modest because plants are building roots. The second year improves. By the third year, the garden may look full, layered, and alive with movement. That slow development can be hard for homeowners used to instant results. But once bees, butterflies, and birds begin visiting regularly, the space feels less decorated and more inhabited.

There is also a neighborhood lesson. Urban gardens are public-facing, even when they are privately owned. People notice them. Some ask questions. Some compliment the flowers. Some wonder why the seed heads are still standing in fall. A tidy edge, a small sign, or a defined path can help communicate intention. The goal is not to make nature behave like plastic landscaping. The goal is to show that habitat and beauty can share the same address.

Driveway apron projects offer a different kind of wisdom: structure is invisible until it fails. Most of the important work sits below the surface. Homeowners may admire the cobblestones, but the base, compaction, slope, and restraint are what keep the project from becoming a lumpy regret. This is why careful preparation matters more than speed.

Anyone replacing an apron should expect demolition to be louder, heavier, and messier than the highlight reel suggests. Old brick or concrete rarely leaves politely. There may be hidden base problems, awkward transitions, or drainage issues that were not obvious at first. The best approach is to plan the project in stages: confirm rules, mark the area, remove material safely, inspect the base, correct problems, and only then install the finished surface.

One of the most satisfying parts of a cobblestone apron is the immediate visual payoff. Unlike a young garden, which needs time, hardscaping gives a crisp result right away. The entrance looks intentional. The driveway feels framed. The street-facing side of the home gets a quiet upgrade that does not scream for attention but definitely clears its throat.

Together, the two projects create a useful homeowner philosophy: improve what people see, but do not neglect what supports it. Plant flowers, but build soil. Install cobblestones, but prepare the base. Add curb appeal, but think about water, wildlife, maintenance, and local rules. That is the sweet spot where a home exterior becomes more than pretty. It becomes durable, useful, and connected to its surroundings.

Conclusion

S23 E22: Urban Gardens, Apron Driveway works because it celebrates two kinds of home improvement: the living and the lasting. Jenn Nawada’s Detroit garden segment shows how native plants, pollinator habitat, and elevated herb beds can make urban spaces healthier and more useful. Mark McCullough’s driveway apron project shows how careful hardscaping can strengthen a home’s entrance while adding timeless curb appeal.

The episode is not just about bees and cobblestones. It is about paying attention to the parts of a property that quietly shape everyday life. A garden can feed pollinators and people. A driveway apron can handle traffic and improve the face of a home. And with the right planning, both can make a small outdoor space feel smarter, stronger, and a lot more loved.
