Behind the Scenes Feb. 26, 2010

Newly Potted Roses

This week we are starting a new section on our blog to give you a peek at what goes on behind the scenes, sometimes months before the plant ever appears for sale. Hopefully, this will bring everyone to a deeper appreciation of what goes into getting seeds ,cuttings, bare root plants, and plugs to quality finished plant, and how long it may take to get them there.
Some of the tasks accomplished this past week included; seeding of some spring vegetables, including eggplant; planting million bell hanging baskets with plants that were started weeks ago; taking ivy and vinca vine cuttings to be rooted and grown for selling in spring; and completing the planting of over 400 varieties of perennials.
Greenhouses that have been closed over the past few months are being cleaned and sterilized in preparation for all the annuals being planted for spring. Speaking of planting, you wouldn't believe all the pots we use on a daily basis, not to mention soil and fertilizer!
This week concluded with final planting of approximately 2100 bare root roses from Jackson & Perkins and Weeks, including four of the newest varieties: Pumpkin Patch, Sedona, Ch-Ching, and Monkey Business. This represents only four of 125 varieties we will have available. We will also have tree standard roses in 2' & 3' sizes, as well as a double ball topiary standard.

Houseplant Topiaries

Topiaries

Topiaries were first created for outdoor use. However the concept of a living sculpture is also a popular way to grow and display several types of indoor houseplants and tender herbs.
Ivy is probably the houseplant most commonly used as an indoor topiary. Ivies grown indoors prefer to be kept in a bright light location with moderate temperatures. It is beneficial to rotate them to the light source to maintain a full and balanced appearance.
Dry warm air caused by heating and cooling systems can rob topiaries of some of their moisture. It is helpful to treat Ivy topiaries with a monthly shower of water or a mild solution ( 1 tsp. to 1 gal.) of Dawn or Joy dish detergent. This rinses the dust off the foliage, thereby discouraging spider mites.
Allow the Ivy topiary to dry out between waterings, then drench the plant thoroughly. Fertilize every other watering with half strength houseplant fertilizer.
The shape of topiaries can be maintained by pruning or winding the tendrils around the topiary frame. Remove any dead leaves or dying stems that may appear.
Other houseplants can also be used to create a living topiary. Angel Vine and Jasmine have a more delicate leaf shape and create a lovely appearance. The herb Rosemary is frequently displayed in topiary form and gives the added pleasure of it's wonderful fragrance.

Cineraria
Senecio cruentus

Cineraria is a popular florist plant that makes a lovely centerpiece for your table. Available February through March, it's masses of daisy like flowers in a broad spectrum of colors will add splash and cheer to mid winter grays outside. The flowers rise above beautiful foliage, some varieties of which have colorful undersides to their large leaves as well. Cineraria do not like to be in direct sun, but a well lit location is ideal.
The soil should be kept moist, but not soaking wet. These beauties prefer cool temperatures: 60-65F during the day, 55-60F at night. Treat this plant as an annual and discard after it is finished blooming. It should bloom for several weeks once it is fully open though, much longer than a fresh bouquet of flowers!

Primrose

Primrose
Primula acaulis

Tired of winter's cold gray weather? The perfect pick me up is to stop in the greenhouse for a few of these brightly colored, sweetly fragrant plants. Their color palette ranges from white to red, to shades of yellow, pink, and deep purple. Large numbers of these bright beautiful blossoms are clustered in the center of the leaves' rosette pattern, creating a nestled bed of color in the midst of dark green paddle shaped foliage.
Primrose prefer cooler temperatures (55-60F), but will do quite well in your house if you can stay around 67-68 degrees. An east or west facing window sill where they will receive lots of bright indirect light and perhaps cooler temperatures would be best. These plants want to be moist but not wet all the time, so water only when the soil surface feels slightly dry to the touch. Remove dead flowers by pinching them off near their base, and fertilize according to directions on your fertilizer package. In spring after danger of frost, you can plant these perennials outdoors in semi shade in well drained soil. With some winter protection, they will be up again in spring with the crocuses, once again delighting you with riots of color to chase away the winter blahs.

Gardenia

Gardenia

It is hard to find a more beautiful and fragrant plant than the Gardenia. However, it can be a temperamental beauty.
The Gardenia needs bright light but not direct sunlight. It prefers cool temperatures at night (55-65F), and slightly warmer during the day, and also requires a humid environment which can be accomplished by standing the pot on a large tray of pebbles which are kept wet at all times. Keep the soil evenly moist and water with tepid or lukewarm water. When fertilizing, use an acid based fertilizer.
The Gardenia can be moved outside in late spring when there is no longer a chance of frost. A north or northwest location out of direct sunlight is ideal. Remember to keep the soil moist, and this plant will bring you many years of beauty and fragrance.

Orchid Cactus

Orchid Cactus
Epiphyllum

Orchid Cactus are very unique plants. Their native habitat is the jungles of south and central America and Mexico, but they will perform well as indoor houseplants if given some extra humidity. Humidity can be enhanced by placing a pebble tray with water in the pebbles under the plant pot. Their very fragrant flowers come in nearly every color except blue and are typically five inches across. They bloom spring through early summer when temperatures are warmer and daylight hours are longer. They need room to grow, at least a space three feet wide, that receives medium light. Morning or late afternoon sun, but no hot direct mid afternoon sun are the ideal lighting conditions. They prefer a rich well drained soil, and require very little fertilizer, preferably in early spring and then once more after blooming. Because their thick fleshy stems retain water well, they really only need to be watered once or twice a week spring through fall, then very sparingly during winter.If you supply your Orchid Cactus with these growing conditions, you will be rewarded with beautiful fragrant flowers year after year.

Christmas Cactus

Christmas Cactus

Christmas Cacti have been favorite holiday houseplants for many years. They are easy to grow, and if given proper conditions will bloom regularly every Christmas. They come in a myriad of bright holiday colors including red, pink, and peach, as well as white. Despite the cactus name, these plants do not like to get desert dry between waterings like true cactus plants do. These are native to forests in Brazil and are frequently found growing in the crooks of branches in tropical forests along with orchids. Thus they prefer to be watered thoroughly when the surface of the soil is dry to the touch, then allowed to dry to the touch again before watering.
To encourage blooming, place them in a cool place, preferably around 50F for a few weeks, and cut back on water during this period. Once they set bud, keep them away from cool or warm drafts and resume proper watering, otherwise your buds will fall off without maturing into full flowers. Don't fertilize them during their flowering period, and allow them to rest for a month or two after flowering before resuming fertilizing. Any houseplant formula fertilizer will suffice according to directions on your fertilizer package. In the house they prefer bright indirect light, and can be placed outdoors in the spring and summer in a shady area.
Christmas Cacti prefer to be tight in a pot, but if repotting is necessary wait until early spring and use a well draining soil mixture. Choose a pot size only one size larger so as not to stress the plant. They also take well to pruning and shaping, but again wait until early spring to tackle this task. Leaf segments from pruning root easily in a rooting medium, allowing you to share this wonderful plant with others.
If you care for your Christmas Cactus properly, you will be enjoying it for many years. A number of people have related how they have inherited these plants from their Grandparents and know they are 30-40 years old! A true testament to their longevity and easy care!
