When Should A Gardener Cut Flowers?

A cut flower garden is a type of garden that focuses on harvesting fresh flowers for arrangements and bouquets. The choice of flower varieties depends on factors such as size, color, and bloom time to maintain a continuous supply of flowers. Cut flowers can be used to create beautiful bouquets for various occasions, such as for mantlepieces or dinner parties. To maintain the longevity of your bouquet, it is essential to cut flower stems periodically, choose a suitable vase, make flower food, and avoid sunlight.

When planning a cut flower garden, map out your design and layout on paper, scan your garden, and draw out a scale replica of your garden. For beginners, this guide will guide you through the process of growing a cut flower garden, from selecting the right plants to using a floral preservative.

Care for cut flowers involves using a floral preservative to keep the water clean, provide carbohydrates or sugars, and cut flower stems at a slant to increase surface area and water update. Remove any foliage that would be under water. Once the bucket is full or harvested, bring it into a cool, shaded space to arrange.

There are different types of cut flowers, their flowering times, propagation methods, and stages of development. Most flowers are best picked when they are just starting to show color, while those in full bloom will go over more quickly. Spike arrangements, such as foxgloves and gladiolus, are best picked when the lowest flowers have just opened.

For beginners, planting a garden of annual cut flowers is recommended for their ease of growth from seed. Cut flowers at the proper stage of development and when they are most turgid (fully hydrated). Some plants can also be propagated from basal cuttings. Starting small and cutting often is crucial, with some flowers being able to branch and become bushy.

Do cut flowers need direct sunlight?

Cut flowers do not require direct sunlight for long life, as they have been cut away from the main plant. They need a moderate environment with plenty of visibility to enjoy their beauty. However, it is important to consider the placement of cut flowers under and around lighting sources. Direct sunlight can cause the flowers to dry out more quickly and heat them, leading to shriveling, wilting, or drooping buds.

Indirect sunlight is generally fine, but direct sunlight for just a couple of hours a day can damage the flowers. In summary, cut flowers do not need direct sunlight for long life, but they should be placed in a moderate environment with plenty of visibility.

Do flowers grow back after being cut?

Cut flowers, such as roses, hydrangea, lilac, honeysuckle, and azaleas, can grow roots with proper treatment. To propagate cut flowers, cut off a piece of the stem and encourage it to root. Most plants propagate sexually through pollination, flowering, and seed development, but some can also propagate asexually by rooting cuttings. To propagate cut flowers from cuttings, act while the bouquet is fresh by cutting off a piece of the stem 2 to 6 inches long with two or three sets of leaf nodes. Remove flowers and any leaves on the bottom nodes.

What are the best conditions for cut flowers?

Store cut flowers in a cool place, between 40° and 60°F, for immediate use or arrangement. For longer storage, 33° to 35°F is ideal. A refrigerator can be used for short-term storage. Some plant species require special care, such as singing or burning stems to prevent excess sap loss. Woody plants like lilac may need to cut stems twice to ensure adequate water uptake.

When caring for cut flowers, use a floral preservative to keep the water clean, provide carbohydrates or sugars to developing flowers, and extend their vase-life. Avoid using sugar, aspirin, tea, pennies, rusty nails, bleach, and citric acid, as they can shorten the vase life of cut flowers. If you don’t have a preservative, use clean water without additives.

Does cutting flowers encourage growth?

Cut-and-come-again flowers are cut flowers that continue to produce more blooms as you harvest them. This is achieved by encouraging the plant to branch and grow multiple stems from the leaf nodes below the cut, resulting in more new blooms in the future. This method provides a longer harvest window, allowing you to pick on the same plant for several weeks and cutting every blossom as it becomes ready.

Zinnias are a popular cut flower due to their mid-summer blooms and long vase life. Zinnia seeds are readily available in spring, and once the seeds have started blooming, more blooms will come. This method is ideal for steady floral arrangements.

Should you cut flowers after they bloom?

Deadheading is a pruning technique that removes old growth and seed heads from plants to promote new growth and re-flowering. It involves pinching or cutting off flower stems below the spent flowers and just above the first set of full, healthy leaves. Deadheading is best done when a flower’s appearance begins to decline, and the frequency depends on the species and weather conditions. Deadheading can enhance the flowering performance of many plants and is essential for maintaining healthy plants throughout the growing season.

When dead blooms are left clinging to the plant, they sap the plant’s nutrition and strength, preventing it from producing new and colorful blooms. Deadheading redirects energy from seed production to root and vegetative growth, resulting in healthier plants and more vibrant blooms.

Is it better to cut flowers in the morning or evening?

Early morning is the best time to cut fresh flowers, as they have had the benefit of cool night air and morning dew. As the day warms up, flowers gradually dehydrate, making them firm to the touch. In late spring and early summer, when your garden is in peak bloom, it’s the perfect time to create a stunning bouquet from the fruits of your labor. Cutting ensures that some of your flowers will be spared from being destroyed by gusty winds or heavy summer rain. Additionally, cutting encourages more flowering throughout the summer and even into early fall, performing the same function as deadheading, promoting more blooms by delaying the onset of fruit.

Which month is best for plant cutting?

To take softwood and hardwood cuttings, fill pots with compost and water them before taking them. Take cuttings early in the day when the plant’s stems are full of water and place them in a plastic bag to prevent drying out. Choose a strong side shoot with no flowers and cut a piece between 5-10cm (2-4in) long, just below a leaf joint. Remove all leaves from the lower half of the cutting and pinch off the growing tip. Dip the bottom end of the cutting in hormone rooting powder if available to help produce roots and reduce the risk of bacterial infection.

Using a dibber or pencil, make a hole in the center of the compost and insert the cutting so that the lowest pair of leaves is just above the soil surface. Firm the compost around the cutting. Label the cuttings and place them in a propagator with a bottom heat of 18-24ºC (64-75ºF) or cover each pot with a clear plastic bag and place in bright but indirect light. Water regularly to keep the compost moist but not wet.

Take hardwood cuttings in autumn after the plants have dropped their leaves and are dormant, but don’t take cuttings in frosty weather. Prepare a narrow trench outside in a sheltered spot for the cuttings to stay in for most of the following year. For a few cuttings or without space for a trench, use pots filled with a 50/50 mix of multipurpose compost and grit.

Choose a strong, pencil-thick woody shoot that has grown in the current year and cut it off close to the base. Cut it into lengths 15-30 cm (6-12in) long, using a sloping cut to shed rainfall and a straight cut to maintain the cutting’s position. Space cuttings 15cm (6in) apart in trenches and leave them in the trench or pots until the following autumn. Water in dry periods to prevent compost drying out.

When to pinch flowers?

Pinching flowering plants is generally recommended before they develop their first buds, typically when they are 20-40cm tall and have at least 4 to 5 sets of true leaves. If the plants have already formed flowers, pinching them is acceptable, but only a few buds or flowers may be lost. Pinching out plants that have already formed side branches or shoots is also acceptable. The pinching technique is simple, but the challenge lies in trusting the process will yield stronger plants and more flowers.

Why not to cut flowers at night?

The optimal time to cut flowers is in the morning due to high humidity levels, cooler temperatures, and increased hydration. However, flower varieties that close at night may require more time to fully open, making late-afternoon timing best. If morning cutting isn’t feasible, early evening is a great alternative, as flowers benefit from cooler temperatures and added energy and carbohydrates from photosynthesis. Cutting flowers at the wrong time can lead to premature wilting, dehydration, and reduced vase life. Midday cuts may also suffer from reduced water absorption, further reducing vase life.

Do I cut off dead flowers?

Deadheading is the process of removing fading or dead flowers from plants to maintain their attractiveness and encourage more blooms. It is best to remove spent flowers as soon as they look scruffy, regardless of the season. For some plants, such as summer bedding, deadheading daily is recommended, while others, like border perennials, should be deadheaded once a week or every other week. Deadheading helps maintain longer flowering periods, neatens plants, encourages more flowers, and prevents scattering of petals. Most garden plants benefit from deadheading, but those that produce decorative or bird-friendly seeds and fruits should be left.

When should flowers be cut back?

Pruning perennials is a crucial process for extending the bloom period and promoting repeat blooming. Deadheading, the removal of faded or spent flowers, can give life to your garden through prolonged blooming or repeat blooming. Many perennials benefit from deadheading, such as Columbine, Phlox, Black Eyed Susan, and Stoke’s Aster. To prune, pinch off the flower stem below the spent flower and above the first set of leaves. For large groups of flowers, shear back the entire plant.

For compact plants with more flowers, use the perennial pruning technique of pinching to form bushier plants with more flowers and reduce plant height to eliminate staking. This technique encourages branching and doubles the number of blooms by cutting back two stems for every stem cut back. Pruned flower stalks will bloom 2-3 weeks later than normal, and flowers may be smaller than normal. Examples of plants that benefit from pruning include Phlox, Asters, Mums, Sedums, Beebalm, Joe-Pye Weed, Monkshood, and Sneezeweed.

To prune perennials, remove 1/3 to 1/2 of the plant’s top growth in spring, and fall bloomers should be cut back by July 4. This helps to create stronger plants, more blooms, and time-blooming.
