AGC Garden of the Month: Sept. 2025

903 Stoneridge Avenue

Gardens catch our attention for various reasons. It might be a striking new plant we haven’t seen before, or the scent of a blossom wafting on the breeze, or the image of a butterfly waving its wings at us! This month, the pergola at 903 Stoneridge Avenue is compelling for its ability to create a garden room much enjoyed by the owners, Christina and David Boenitz.

The Meadow Brook Park neighborhood located close to where N. Mountain crosses over I-5 enjoys stunning views of the hills but represented a challenge for developers in integrating the architecture with the topography. The Boenitz residence experiences a drop of three feet from the street to the front door and an additional twelve feet to the rear property line. In addition to the critical matter of drainage, the aesthetics of an entry garden were paramount.
Incorporating a handsome pergola into the design addressed this issue quite admirably and afforded the opportunity of creating a pocket garden for plants to thrive in.

The pergola, constructed of six by six inch posts and six by twelve inch cross beams, complements the front door in scale and proportion. Cross beams are capped with aluminum thereby ensuring longevity and shade cloth provides relief when necessary. Three colorful, ceramic pots have been tucked into pockets where three corners of the arbor are each supported by three posts. Christina has nurtured a self-pollinating Pineapple Guava (Feijoa sellowiana), a Kiwi vine (Kiwi Magic Hardy, Kiwi Combination) and a Heavenly Bamboo (Nandina domestica) in these pots. The flagstone patio is interlaced with Creeping Thyme and a natural gas fire bowl entertains after dusk when rocking chairs are pulled up near-at-hand. Christina has added numerous pieces of glass art throughout the garden.

The garden room is defined by four living walls. Street-side, ceramic pots are planted with a semi-dwarf McIntosh Apple, a 20 th Century Asian Pear and two NZ Flax (Phormium ‘Maori
Maiden’). Non-invasive, clumping Bamboo (Fargesia rufa ‘Green Panda’) alternating with Scotch Heather (Erica x darleyensis) define the edging at the end of the patio and Snowball Hydrangea screen the foundation. The front door is flanked by Star Jasmine Trachelospermum jasminoides) trained on trellises elevated further by large tapered pots. Opposite the front door is a Weeping Norway Spruce (Picea abies ‘pendula’), tall and slender to accent the entry.
The pergola is extended by a portico over the entryway reaching across the front face of the residence where privacy for sitting is ensured by a grove of trees planted in the side yard (Dogwood, Japanese Maple and a Magnolia ‘Little Gem’).

Several large shade trees, notably maple and oaks, are planted along a decomposed granite path leading down from Stoneridge Avenue to an alley at the lower elevation. The Boenitz’s
chose to connect their patio to this path which necessitated the building of a stone retaining wall artfully complementing the flagstone material used in the patio. The handsome stone wall at the foot of the path mimics the wall built up above.

A wisteria vine is being trained along the top of the fence at the foot of their property. The driveway is edged on the northern boundary by a living screen of Leyland Cypress which completely blocks out rooflines looking out from the residence. All the trees on the property, including the oak and maple, are maintained by Tate with Table Rock Tree Care.

The rear garden is private but the Boenitz’s have maximized its potential by constructing raised vegetable beds and utilizing trellises to the fullest extent. Pathways are covered with artificial turf for easy cleanup and a small greenhouse provides a workspace for tender veggie starts.
Christina has always been a gardener and she has pushed the envelope on what she can grow here. This is their eighth year living in Ashland and in addition to the plant material that accents the front garden, Christina is growing a pomegranate, basil, bush cherry, blueberry bushes, a Nigroni fig, green beans, butternut squash, tomatoes, ‘Sugar Cube’ melons, chard and sweet peppers. Ferns, lavender, salvia, rhodies and rosemary were all in evidence.

Visitors marvel at the vigor and health of all the plant material, evidence that it is well cared for. Tender plants are moved into a cellar during the winter months where solar grow lights provide the necessary spectrum of light. Christina enthusiastically believes that her time and hard work is rewarded many times over. Family and friends enjoy this bounty and the remnants are easily recycled with an electric countertop composter. A gardener is hired once a year to help with maintenance and clean up.

It is profoundly evident that the challenges presented by the topography of this landscape were more than compensated for by the structures built at 903 Stoneridge Avenue. The pergola and portico create a welcoming space for entertaining in the front garden while the raised vegetable boxes and trellises provide increased productivity for the table, a feast for both the eye and the palate. Thank you, Christina and David, for sharing your remarkable gardens with us.

DIY: Seedling Mix

Seed starting mix is known as a soil-less mix , and unlike garden soil or potting soil, it is a sterile pathogen free growing mix. This is important because pathogens can kill seedlings while they are germinating, so growing seeds in a soil-less mixture increases their survival rate.  After your seeds have germinated and grown two true leaves, then they can be transplanted into containers filled with potting soil. 

DIY Seedling Mix recipe:

4 parts screened (mature) compost
1 part perlite
1 part vermiculite
2 parts coir (coconut fiber)

 

Use hands, or trowel to mix until ingredients are well combined.

Wet the seedling mix only until you can form a loose ball (water should not be dripping from the mixture)

Fill pots, or trays, with seedling mix

Plant seeds to the depth shown on the seed packet, cover seeds with seedling mix, then use a spray bottle to gently water the seeds.

Label your pots or trays with seed variety.
