Tips to Make the Most out of Your Annual Plants

We see them just about everywhere around this time of year in hanging baskets, patio pots and arranged beautifully in garden beds. Annual plants, such as petunias, geraniums and begonias to name a few, complete their life cycle within a years’ time. Being both fairly easy to care for and their ability to look stunning all season long, annuals are perfect for any gardener, with or without experience.

During the pandemic many novice gardeners picked up the hobby of gardening though annual plants, transforming their garden space into a blooming oasis. Continue reading if you are new to these beautiful outdoor plants and would like a few care tips or would like to learn more about them.

LIGHT

Most annuals require full sun, at least six to eight hours daily. Annuals that thrive in the sun include geraniums, petunias and marigolds.

If partial shade is an option or necessity based on where you want to place the flowers, good varieties include begonias, impatiens, fuchsia and coleus.

WATER

Annuals don’t have deep roots because they focus on producing flowers. Be aware of outside conditions such as heat, direct sunlight and wind which can dry the soil out quickly.

Most annuals like soil that is slightly or evenly moist two to three inches down. A rule of thumb is that when the soil is dry one inch below the surface, its time to give the plant water.

The lush foliage of some annual plants can make it difficult for water to make its way down to its roots, so do more than “sprinkle”, water deeply.

When container gardening, check often for water and use containers with drainage holes.

NUTRIENTS

Container plants don’t come in nutrient-rich soil, rather a potting mix including peat moss. Providing your plants with a water-soluble fertilizer on a weekly basis, whether in the garden or in a container will help to make the plant as beautiful and healthy as possible.

NEW GROWTH

Sometimes annuals benefit from a bit of “refreshing” during the heat of the summer. Just pick or trim tired blooms and give them some water-soluble fertilizer and they’ll spring back.

By following these steps, you will be sure to enjoy healthy, vibrant annuals all summer long.

A Flood or a Drip: our greenhouse watering systems help improve efficiency and plant quality

To understand how flower growing has changed in the past four decades, consider 1, 7 and 9.
Those numbers identify the three remaining greenhouses at Royer’s corporate complex in Lebanon. As the breaks in number sequencing suggest, Royer’s had more greenhouses back when we grew our own flowers – nine total at the corporate complex and six more nearby on Colebrook Road.

However, a perfect storm occurred in the 1970s: An oil embargo made it prohibitively expensive for Royer’s and other florists to heat their greenhouses, while Bogota, Colombia was found to offer ideal temperatures and sunlight for growing flowers. In the intervening years, most flower growing has shifted to South America.

Today, as Tom Royer, CEO, pointed out, Royer’s isn’t a grower but rather a holder of plants. That is, the company buys from growers both inside and outside the United States. Those plants and flowers are delivered to the corporate complex, where they reside before being distributed to Royer’s 16 stores in seven counties.

Much of the “holding” occurs in the three greenhouses which houses equipment designed to improve plant quality and operating efficiency.

TURN OF A TIMER

Over the past few years Royer’s has installed new flood tables in each of its remaining greenhouses. This automatic plant watering system isn’t new to Royer’s though, the company has utilized this technology since 1999.

Each flood table has its own water reservoir. Once per day, we turn on a timer that floods the table for typically 15 minutes but longer if external conditions warrant. The plants, lined up in rows, drink through openings in the bottom of their containers.

Drip Irrigation systems are also utilized in the greenhouses, specifically for when we have hanging baskets, such as around Mother’s Day. Each water line is placed in or above a hanging basket and when turned on, the water will slowly be absorbed into the soil.

With both systems, a worker doesn’t have to tend to each plant individually, a time-consuming proposition considering the hundreds of containers.

“Now I can water all these plants in 15 minutes,” Tom said, “whereas it would take somebody two or three hours to do that day after day after day.”

CONSERSVING WATER

The reduced labor also will improve quality, as watering won’t ever have to be sacrificed for the sake of other time demands. (In some cases, watering from above can cause damage, such as stains on violet petals.)

Of course, not all plants need the same amount of water.

“Just like people, they drink different, they eat different,” Tom said. Reflecting those differences, Royer’s separates plants by type (all violets on one bench, for instance) or at least by pot size and waters them accordingly.

Water that isn’t absorbed by the plants goes back into each table’s reservoir so it can be conserved and reused.

Another greenhouse variable is sunlight. In greenhouse 7, which holds blooming plants, a system of cables and pulleys operates the fabric shade cloths. By controlling the amount of sunlight, Royer’s can maintain an internal temperature of 75 degrees.

“If these shade cloths weren’t on here,” Tom noted on a warm, sunny day in early October, “it would be a lot hotter in here.”

Tom said the expenditure on flood tables and the shade system are the price of doing right by customers.
“It’s an investment in the future,” he said. “It’s worth it to me to do that because long term I’m going to have better product. It’s going to be taken care of properly. It will grow better, too.”

Extending the Life of your Spring Bulbs

Even after the Easter Bunny has visited and the last eggs are hunted, Easter bulbs – such as daffodils (narcissus), hyacinths, and tulips will bring beauty and color into your home. In fact, you can make the flowers last a lot longer by following these few tips.

The key to making the blooms last longer is to keep the plants in a cool place, such as your garage or porch. For smaller plants, such as a single-bloom hyacinth, finding space in your refrigerator will work just as well. This will stall the normal aging process, extending the life of the blooms.

Keeping your bulbs in a cool place overnight or while at work will help extend the life of your bloom and allow for maximum enjoyment when you are at home. Not all bulbs are freeze tolerant so keep temperatures in mind, especially overnight.

Like any living plant, it’s also important to keep the plants watered. Most bulbs like to be watered at soil level rather than overhead. Do not overwater, the soil should not be saturated at all times.

After your bulb plants have finished blooming, let the plant die back into itself. Allowing the leaves to yellow and wither before removing will help nourish the bulb for the following year by. Keep in mind this is different from deadheading the bloom which can be beneficial to bulb growth. Keep the bulb in its pot and store in a cool, dark place. In early fall, separate the bulbs and plant them in your garden in anticipation of their blooming again next spring. Be mindful that some bulbs will not come back depending on climates, among other reasons, following these tips does not guarantee that your bulbs will bloom again.
