Rooftop Container Vegetable Garden

Rooftop gardens require thoughtful planning in order to get the most from them. Start by assessing your site as you would for any garden on land level.

Note any irregularities such as pools of standing water, areas of shade or dampness, and windy spots on your rooftop that might affect what crops grow best there. These conditions could influence what plants flourish best on it.

Eggplant

Eggplants add color and texture to vegetable dishes when prepared either on the grill for dinner, baked in lasagna or stuffed with meat and cheese – perfect for vegetarian meals! Additionally, eggplants grow well in containers, making an attractive addition on rooftops where space may be limited. If your building allows it legally and structurally, consider creating a rooftop container vegetable garden!

Eggplants are heat-loving plants that need ample sunshine and plenty of water in order to thrive. Begin planting seeds six to eight weeks prior to the last frost date indoors, then transplant after soil temperatures reach 70 degrees Fahrenheit outside. After planting, water thoroughly afterward so as to keep soil moist without becoming saturated; this will prevent air bubbles forming as well as prevent roots becoming waterlogged resulting in root rot.

As with other nightshades, eggplants require rich, well-draining soil that is slightly acidic at around 6.5. When growing them in containers it’s essential that a container with drainage holes and using high quality potting mix provides good aeration; since eggplants enjoy heat so quickly they need stakes or trellises installed to provide support as they grow quickly and sprawl outward.

Growing eggplants in containers requires regular fertilization to ensure a plentiful harvest and healthy plant development. A balanced liquid fertilizer should be applied every two to three weeks throughout the growing season. A layer of mulch helps conserve moisture, decreasing water usage.

Since rooftops can be windy environments, be sure to protect your vegetables with a row cover or another method to fend off damage from gusts of wind and gusty conditions. Also keep an eye out for insects like flea beetles and aphids which could potentially invade and infiltrate them as well as damaging winds and gusts.

Though most vegetable gardens tend to focus on greens and tomatoes, containers provide the opportunity to cultivate nearly every conceivable type of crop. Many vegetables actually thrive when grown in pots; in fact, many thrive more efficiently this way than being grown on their own in soil conditions – for instance kale thrives easily in pots while still managing colder temperatures efficiently, making it a fantastic fall choice.

Kale

Kale is an easy kitchen staple to grow both indoors and outdoors in any container or the ground, costing PS2-4 per packet of seeds that germinate quickly if planted early and outdoors in May in the UK. Expect harvest leaves during summer, autumn and winter if sowing early; harvest more if harvesting regularly! There are various varieties such as frizzy red leaves with curled edges; curly green; Cavolo Nero; Nero di Toscano’s; Frizzante di Nero di Toscano’s; Frizzante di Toscano’; all excellent options when growing kale!

To successfully cultivate kale, you require a sunny site with excellent drainage and structural strength to support containers without breaking under their weight. If space is at a premium, try growing in pots instead or use a plant caddy for effortless movement of containers around without lifting.

Ellen Spector Platt has created an idyllic rooftop garden on her Manhattan high-rise apartment building common roof for over eighteen years now, growing various species that attract pollinators and birds while adapting them to her climate’s heat. Her containers hold 75 containers full of pollinator-friendly plants as well as drought tolerant species adapted specifically to her site; often butterflies, songbirds and even pollinating moths visit.

Straw Bale

Straw bales, made of leftover stalks from California rice fields, are an annual agricultural bi-product that are renewable annually. Available locally through farmers or purchased directly from merchants, straw bales offer cost-effective building material alternatives with lighter transport requirements than wood products – perfect for rooftop installations!

Load-bearing straw bale walls are typically constructed vertically and plastered with either lime-based renders or earth renders for best results. Lime renders allow the wall to breathe by preventing moisture from seeping into its bales and rotting or creating internal structural issues. Straw bale walls also possess high compressive strengths which enable them to resist normal stresses of house buildings such as wind loading and thermal movement, making them suitable material for earthquake zones.

Straw bale homes not only reduce overall energy costs, but are also healthier living environments. Traditional building materials like fiberglass insulation and wood studs contain harmful chemicals which pose health hazards for both construction crew members and residents of a home. Furthermore, replacing lumber with straw reduces pressure to log old-growth forests which preserve ecosystems that provide habitats and support for wildlife as well as air quality and soil stability.

As a building material, straw offers superior hygrothermal insulation than wood and concrete, with research showing it is significantly better. Research also demonstrated its hygrothermal properties are generally independent of density; however, thermal conductivity depends on macrostructure; perpendicular or random orientation of straw strands had lower conductivity than parallel ones.

Straw bale walls allow for installation of many features typically found in conventional buildings, including electrical cables and plumbing, such as electrical outlets and plumbing pipes. Walls can be reinforced with wood, metal, or stone cladding to accommodate these items while straw bales can be carved to form niches and window seats; heavy features like upper cabinets are supported with wooden pieces inserted into the bales that fasten securely to timber framing with spikes.

Cardoon

Cardoon (Cynara cardunculus), more commonly known as artichoke thistle, is an herbaceous perennial belonging to the same family as sunflowers and globe artichokes. Cultivated for its edible leaf stalks that resemble thick celery stems with prickly leaves, this cool-weather vegetable typically shows up in markets between late fall and early spring and makes an excellent addition to soups, stews and braises dishes.

Cardon stalks boast an earthy, nutty flavor reminiscent of artichoke hearts, sunchokes or celery root. Additionally, their sweet crunchiness softens when cooked steamed or braised in cooking liquid – making this vegetable a key component in Lyonnaise cuisine and often served stuffed like artichokes or as part of a hearty gratin dish.

Cardoon can be grown in both container gardens and soil gardens, though for optimal results you’ll need an open area receiving full sun. Once planted, this vegetable requires lots of watering and regular feeding with aged compost added prior to sowing. As this vegetable takes time to mature before harvesting.

Like many leafy vegetables, cardoon must be blanched to reduce its bitter taste. Blanching involves shading it from sunlight by covering its entire plant with soil; more recently however, floating row covers made of plastic or cloth may be used instead.

Pistils of this plant can be used as an effective, vegetarian-based replacement to animal-derived rennet in cheese production. Furthermore, these pistils can also be found as an ingredient in popular North African and Southern European tagines like Couscous Tagines that involve boiling cardoon soup for cardoon soup to be eaten alongside bagna cauda sauce.

To prepare cardoon for cooking, remove any inedible parts and peel away fibrous strings with a paring knife or vegetable peeler. Next, cut stalks into one- or two-inch pieces before submerging in cold water acidified with lemon juice to prevent darkening during the cooking process. Finally, boil for 20 to 30 minutes for best results.
