Jasmine: Year-Round Fragrance with Seasonal Peaks

Why Choose Jasmine?

Jasmine fills warm evenings with a captivating fragrance that draws in pollinators. Its aroma evokes memories of long summer nights spent at outdoor cinemas and leisurely walks along scenic seaside paths. You can enjoy its blooms from spring to late summer, and some varieties even flower in winter.

Seasonality & Blooming:

Spring: Best time to plant your new jasmine, as roots establish before summer heat.
Summer: Peak blooming (June–August); don’t forget to regularly water and feed to encourage lush flowers.
Monsoon (where applicable): Growth surges, but keep in mind to ensure drainage to avoid root rot.
Winter: Some types (e.g., winter jasmine) bloom with bright yellow flowers on bare stems, while others go semi-dormant.

Optimal Temperatures:

Jasmine thrives at 16–24°C; tolerates down to 4°C, but needs protection from frost.
Humidity: 50–80% is ideal.

Fertilization:

For plants in pots, use a high-potassium liquid feed (like tomato fertilizer) monthly during the growing season. Follow the label instructions for the recommended quantity, typically one capful per 4–5 liters of water for liquid feeds.

Practical Tips:

Plant in spring or autumn for summer-flowering types and in autumn/winter for winter jasmine.
Prune after flowering for shape and more blooms.
Drainage: Add a 2–3 cm (1-inch) layer of pebbles or broken clay pots at the bottom of your planter before adding soil to prevent soggy roots.
Humidity: Place a shallow tray with water and pebbles under the pot to increase humidity on hot days.
Support: Use a bamboo trellis or string to train vines up your balcony railing for privacy and vertical interest.
Scent Maximization: Place near your favorite chair or window for maximum fragrance on summer evenings.

Bougainvillea: Cyclical Color Bursts for Long Summers

Why Choose Bougainvillea?

The vibrant bracts of bougainvillea bring a delightful Mediterranean flair to any environment. These stunning plants thrive in pots, making them ideal for sunny balconies where they can thrive. With various colors available—pink, magenta, purple, red, orange, white, and yellow—you can easily find the perfect shade to complement your space and mood.

Seasonality & Blooming:

Spring: Plant or repot your bougainvillea; begin feeding and watering as growth resumes.
Summer to Autumn: Main flowering season (May–October), with cycles of 5–6 weeks of bloom followed by 6–8 weeks of vegetative growth.
Winter: Your plant goes semi-dormant; reduce watering and stop feeding it. Keep it above 10°C to avoid leaf drop.

Optimal Temperatures:

Day: 18–27°C; Night: above 10°C.
This plant is frost-sensitive, so bring it indoors or protect it if the temperature falls below 10°C.

Fertilization:

In early growth, use a high-nitrogen feed weekly; switch to a high-potassium feed when bracts appear. Regarding quantity, for liquid feed, typically 10 ml per 4 liters of water; for slow-release, follow package instructions. Don’t forget to stop feeding in autumn as growth slows.

Practical Tips:

Needs at least 5 hours of direct sun daily for best blooms.
Water deeply but infrequently; allow soil to dry between waterings to avoid rotting.
Drainage: Before adding soil, place a 3 cm (1–1.5 inch) layer of coarse gravel or pebbles at the bottom of the pot.
Soil Mix: Mix regular potting soil with 1/3 perlite or coarse sand for extra drainage.
Watering: Water deeply, then let the soil dry out before watering again.
Pruning: After each bloom cycle and in late winter, trim back by 10–20 cm (4–8 inches) to keep compact and encourage more flowers.
Pot Choice: Use terracotta pots to keep roots cool, prevent waterlogging, and for a Mediterranean look.

Geranium: Summer-Long Color and Scent

Why Choose Geranium:

Geraniums (Pelargoniums) are a staple for balconies. They provide vibrant color throughout the season; certain varieties even feature fragrant leaves that help repel mosquitoes. With their diverse color palette, geraniums can turn your balcony into a charming garden oasis.

Seasonality & Blooming:

Spring: Plant after the last frost, in mid-May in most regions.
Summer: Prolific flowering from May to October deadhead regularly for more blooms.
Autumn: Prune and prepare for overwintering indoors if frost is expected.
Winter: Dormant; keep barely moist and frost-free indoors.

Optimal Temperatures:

Growth slows below 12°C and stops below 5°C.
Ideal: 16–24°C.

Fertilization:

Use a balanced (10-10-10)* liquid fertilizer every 4–6 weeks during the growing season. Apply half-strength quantity for potted plants (e.g., 5 ml per 2 liters of water). Avoid fertilizing in extreme heat or when the soil is dry.

*(nitrogen - phosphorus- potassium)

Practical Tips:

Overwintering can be done by bringing indoors or taking cuttings before the first frost, and waiting until all frost risk has passed before moving outside.
Drainage: Layer 2 cm (1 inch) of small stones or broken terracotta at the base of pots.
Self-Watering Hack: Place a saucer with pebbles and water under the pot to keep humidity up during hot spells.
Deadheading: Pinch off spent blooms weekly for continuous color.
Mobility: To protect your plants from overheating, use lightweight pots or add wheels to larger containers for easy rearrangement as sun angles change.

Citronella: Lush Foliage and Mosquito Defense

Why Choose Citronella:
Citronella’s vibrant, fresh lemon scent acts as a natural shield against mosquitoes, transforming your balcony into a comfortable, pest-free haven. Just brushing past its lush, grassy leaves releases a burst of citrus fragrance, making citronella the perfect companion for summer evenings spent relaxing, dining, or entertaining outdoors.

Seasonality & Blooming:

Spring: Plant after the last frost, when the soil is warm (like tomatoes).
Summer: Vigorous vegetative growth and rare pale flowers may appear late summer to early fall.
Autumn: Harvest and prune for bushiness.
Winter: In cold climates, bring pots indoors before frost.

Optimal Temperatures:

Citronella thrives at 21–32°C.
Sensitive to frost and needs protection when temperatures are below 10°C.

Fertilization:

Mix aged compost into the soil at planting. For pots, use a balanced liquid feed every 4–6 weeks (e.g., 5 ml per 2 liters of water).

Practical Tips:

Make sure your plant soaks in the sun for 6–8 hours for the best aroma and mosquito-repelling effect.
Water when the top inch of soil is dry; avoid waterlogging.
Drainage: Add a 2–3 cm (1 inch) layer of pebbles at the bottom of the pot to ensure that the water drains smoothly.
Potting Mix: Blend potting soil with sand and compost for light, airy soil.
Placement: Cluster citronella pots around your seating area for a natural mosquito barrier.
Pruning: Trim back by a third in late summer to keep bushy and encourage new growth.

Rosemary: Evergreen Aroma for Every Season

Why Choose Rosemary:

Rosemary is a lush, evergreen herb that delights the senses all year round with its invigorating pine-like aroma. Its needle-like foliage not only adds a touch of Mediterranean beauty to your balcony but also serves double duty-infusing your culinary creations with flavor and naturally repelling mosquitoes, so you can enjoy peaceful, fragrant summer nights outdoors.

Seasonality & Blooming:

Spring: Plant after the last frost; main period of new growth and start of flowering.
Summer: Continued flowering and rapid growth; attracts pollinators.
Autumn: Growth slows; prune after flowering to maintain shape.
Winter: Evergreen in mild climates; bring pots indoors or protect roots in cold regions.

Optimal Temperatures:

Best: 16–27°C
Avoid prolonged frost and wet soil in winter.

Fertilization:

Apply a balanced fertilizer (10-10-10) once in spring (e.g., 1 tablespoon per plant). Avoid high-nitrogen fertilizers, which can reduce aroma and flavor.

Practical Tips:

Place in full sun; afternoon shade helps in extreme heat.
Prune after flowering for bushiness and to encourage new shoots.
Drainage: Place a 2–3 cm (1 inch) layer of coarse gravel at the pot’s base.
Soil: Use a cactus or Mediterranean herb mix for best drainage.
Watering: Let the top 2–3 cm (1 inch) of soil dry before watering.
Companion Planting: Pair with thyme or lavender for a fragrant, edible mini-garden.
Harvesting: Snip sprigs as needed for cooking or cocktails- regular harvesting encourages bushiness.
