How do I plan a cutting flower garden in NB zone 5?

A cutting garden in NB zone 5 should focus on prolific, long-stemmed flowers that bloom in succession from late June through September, giving you a steady supply of fresh bouquets throughout the Maritime growing season. Zone 5 areas like Moncton, Saint John, and the Fundy coast offer NB's longest growing season at 140–150 days, making them ideal for cutting garden production.

Design the garden for production, not display. Unlike ornamental borders, cutting gardens should be laid out in straight rows with 18–24 inch spacing for easy harvesting and maintenance. A 4x8 or 4x16 raised bed works well, oriented north-south for even sun exposure. Full sun — 8 or more hours daily — is essential for maximum flower production. Plan for 10 to 15 different varieties blooming at different times to ensure you always have something to cut from late June through first frost in late September.

Early season (late June–July) flowers include peonies (plant in fall for blooms the following year), sweet William, foxglove, and snapdragons. Peonies are superstars in NB zone 5 — they produce abundant, fragrant blooms and last for decades once established. Start snapdragons indoors 8–10 weeks before the last frost (mid-March for a mid-May transplant) to get early blooms.

Mid-season (July–August) is peak cutting season. Zinnias are the ultimate cutting flower — they're heat-loving, prolific, and come in every colour. Direct-sow after the last frost (around May 15 in Saint John) in successive plantings every 2 weeks through mid-June for continuous harvest. Dahlias are another mid-season powerhouse — start tubers indoors in April and transplant after frost risk passes. In NB zone 5, dahlias bloom from August through frost and must be dug up and stored over winter. Cosmos, sunflowers, and lisianthus round out the mid-season lineup.

Late season (August–September) relies on asters, chrysanthemums, and late-sown zinnias. Celosia and statice provide unique textures and dry beautifully for winter arrangements. Ornamental grasses like Karl Foerster add dramatic vertical elements to autumn bouquets.

Growing tips for NB's climate. Start heat-loving annuals (zinnias, cosmos, dahlias) indoors 4–6 weeks before the last frost to maximize bloom time in the short season. Use season-extending row covers in spring and fall to add 3–4 weeks on each end. Fertilize every 2 weeks with a balanced liquid fertilizer during peak growing season. Deadhead religiously — or better yet, keep cutting blooms for the house, which naturally encourages more flower production.

A productive cutting garden in NB zone 5 costs $200 to $500 in annual seed, bulb, and plant purchases for a 100-square-foot bed, with initial raised bed construction adding $300 to $700. The reward is weekly bouquets from late June through September — a luxury that would cost $20 to $40 per bouquet at a NB florist.
