The classic, Old World look of a garden urn adds a touch of formality to container gardens used to flank porch steps, doors or simply to adorn a patio. Common urn materials include concrete, fiberglass and plastic. Concrete is more authentic than fiberglass and plastic, but concrete is heavy, making it difficult to rearrange the urns when desired. Plastic and fiberglass, by contrast, weigh considerably less and with detailed molds and faux finishes, they can look like metal and concrete. Urns look best when planted with a variety of annual and perennial flowers with different forms and textures.

Urns look best when planted with a variety of annual and perennial flowers with different forms and textures.

Fill the bottom of the urn to the proper depth with a filler material, such as packing peanuts or a mixture of gravel and coarse sand. If the inside of the urn is 18 inches tall, add 9 inches of filler material to the bottom. The filler material saves potting soil that would not be utilized by the plant roots and also compensates if the urn does not have a hole for drainage.

Fill the container to within 1 inch of the top edge with sterile potting mix, using a bagged mix or your own blend, such as a mixture of equal parts sphagnum peat moss, finished compost and perlite or coarse sand. Flowering annuals have shallow roots and need only about 8 inches of soil. If you opt to use larger plants or perennial plants, provide a container and soil depth recommended for the plants you choose, sometimes requiring 16 inches of soil depth or more.

Select plant varieties that fit the scale of your garden urn, including one tall, upright plant, short filler plants and cascading plants. Do not choose a large plant with a mature width of 4 feet to plant in an urn with a diameter of 1 foot.

Plant a tall, upright plant in the center of the urn to create a main focal point for the container garden. Try a spiky ornamental grass, such as purple fountain grass (Pennisetum setaceum "Rubrum"), which grows as a perennial in U.S. Department of Agriculture plant hardiness zones 9 and 10. Alternatively, you might try spiky plants, such as Spanish dagger (Yucca gloriosa), grown in zones 7 through 11, or electric pink dracaena palm (Cordyline "Electric Pink"), a perennial for zones 8 through 10. If you prefer a flowering plant, try a canna cultivar (Canna spp.), such as "Pretoria," or "Black Knight," which grow in zones 8 through 11.

Plant short, wide filler plants around the upright plant, creating a ring about halfway between the center plant and the urn edge. Try any of your favorite annual plants, such as coleus (Solenostemon spp.) and begonias (Begonia spp.), or perennials, such as floss flower (Ageratum houstonianum) or dusty miller (Centaurea cineraria), which are hardy in USDA zones 2 through 11 and 7 through 9, respectively.

Add a few cascading plants evenly spaced around the container edge. Choose foliage plants such as alternantheras (Alternanthera spp.) and sweet potato vine (Ipomoea batatas), a perennial for USDA zones 9 through 11. If you prefer flowering plants, try nasturtiums (Tropaeoleum spp.) or trailing lobelia (Lobelia erinus), which grows as a perennial in zones 10 and 11.

Transplant any perennials to your garden at the end of the growing season and discard any expired annuals. You can put the urns in storage until the following spring, or display material such as willow branches in the urns for winter interest.

caring for an urn plant - information on the urn plant bromeliad

Aechmea fasciata, the urn plant bromeliad, comes to us from the South American rainforests. It is an epiphyte, commonly called an air plant, and in the wild it grows on other plants where it receives moisture from heavy rains and nutrients from decaying debris around its roots. This is important to urn plant care in your home as you will try to mimic its natural conditions.

In the rainforests, rainwater gathers in the stiff rosette of leaves that form the urn. Plant care in the home consists of keeping the center filled with water at all times. For a healthy plant, the water should be emptied and refilled once a week to prevent stagnation. Watch out for dry brown edges of the leaves. Its a sign of dehydration in your urn plant. Care should also be taken with the soil. Keep it moist, but dont overwater. Soggy soil will cause rot at the base of your urn plant bromeliad.

If you live in a hardiness zone of 10b or 11, you can grow urn plants outside as long as you keep them well watered. They arent fussy about soil when grown outdoors, but caring for an urn plant indoor is a bit different. Once again, look at how they grow in the wild. Silt, decaying debris and bits of leaf and bark cling to and build up around the roots of the epiphyte.

In your chosen pot at home, you should try to duplicate this soft, well aerated soil. Orchid potting mix is ideal for this or, if you prefer to mix your own, mix peat moss, perlite, and finely shredded pine bark in equal parts. You need a soil that remains light and well aerated so the roots can easily spread.

Urn plants prefer bright light, but not direct sun and can suffer scorched leaves if moved too quickly from indoors to out during the summer months. They do best in temperatures between 65 and 75 degrees F. (12-24 C.), although they can tolerate higher with regular misting.

Almost everyone who tries to grow urn plants wants them to bloom. Those colorful, long lasting bracts rising from the center of the plant are the ultimate reward in caring for an urn plant. A plant must be at least three years old before it produces a flower stem.

One of the most common complaints of gardeners is the failure of bracts to grow. Urn plants need good light and plenty of it for bract production. If light isnt the problem, then it may be a lack of ethylene gas. To encourage blooming, try placing a quartered apple on top of the soil and using a plastic bag to cover both pot and urn plant.

Bromeliad plants bloom only once before they die, but dont despair. They leave several lovely gifts behind. Once the bract turns brown, continue caring for your urn plant as before even as the leaves turn brown and die. Beneath the dying leaves youll find two or more pupsbaby urn plants. Allow these pups to grow in place until they are 6 inches (15 cm.) tall which usually takes five or six months, and then transfer them to pots of their own.

urn plant: different types, how to grow and care for beginners | florgeous

Tropical plants are considered as some of the best ones to grow as houseplants, not just because of their adaptability to indoor settings but also because of the unique extravagant flair they bring into a room that no other common house plants possess.

A favorite among these beautiful tropical plants is the Aechmea (also known as urn plant or the silver vase). This large-leafed genus of plants come in exotic color splashes and bear one of a kind blooms that will definitely make any space more interesting and fresher.

The name Aechmea was derived from the Greek word for spear owing to the stiff, spear-like leaves of the plant. These leaves gather in a basal rosette form with a hollow, cup-shaped center that catches rainwater in the wild for the plants moisture supply (2).

There are several things unique about this ornamental flowering plant. One is Aechmeas dont have an upper-ground stem and their beauty is predominantly showcased by the spiny-edged foliage that comes in bicolors, striped, mottled, or a combination of these (1).

Filtered sunlight and warm temperature, as when they are in their natural habitat, are the best for growing bromeliads. To achieve the healthy growth and vibrant foliage and blooms in the garden, they must be placed in a partially-shaded or sheltered exposure, facing east or west.

The flowering of Aechmeas relies heavily on light levels. The plant generally prefers partial shade so when placed under bright light, the flowers tend to be fully formed but the color is not as vibrant.

Native in tropical forests, bromeliads like Aechmea prefer high humidity and moist surfaces. Rainwater provides the acidity that they need but in an indoor setting, they can be planted in a peat-based mix and sprayed with decalcified water instead (5).

It is important to keep the Aechmeas growing media only slightly damp because if it is too wet, the crown of the plant may rot. The cup portion of the center of the plant is its natural storage of moisture.

After an Aechmea flowers, the rosette of leaves dies. Several young funnel leaves will develop at the base of the old plant and will eventually form roots and grow into new plants. These are called pups and can be potted separately (3).

Aphids, leaf miners, and mites are some of the most common pests of bromeliads. A specific type of aphids called rice root aphid, dark green or orange brown in color, attacks the roots of Vase plants causing stunted growth.

Leaf miners are larvae of flies, moths, and beetles that create a tunnel-looking pattern on the surface of the bromeliads leaves. Pineapple mites infest Aechmea by sucking out the plant juices through the leaves (2).

This Urn plant is characterized by its chalky-grey leaves and the violet flowers in between the pyramid-forming pink bracts. The grey color of the funnel is due to the white miniscule scales covering the leaves which disappear when touched, come in contact with water, or when there is not enough light.

The funnel is made of attractive orange leaves with red tips. In more shaded areas, the plant is greener but still provides a perfect background to the equally striking panicles of red and yellow flowers. These long lasting flowers are often used as cut flowers with a shelf life of up to 3 weeks.

The rosette of green to dark-green spiky leaves is looser and in the middle of the plant emerges a tall floral stalk composed of red or pink bracts, each housing delicate purple, blue, or white flowers.

The flowers last for weeks, sometimes months and are very striking when in full bloom against the dark leaves. The plant grows a manageable size so it is perfect when potted but makes an excellent groundcover when grown in a compact mass too.

growth and care guide for aechmea bromeliads

growth and care guide for aechmea bromeliads

Aechmea bromeliads are probably the most popular houseplant bromeliads on the market today. The stately plants generally have wide, strappy green leaves that sometimes appear to be lightly powdered. Their leaves have backward-curving spines that can be painful, so be careful how you pick them up. Although the plants themselves are beautiful, their long-lasting flowering bracts are stunning. Usually pink, they rise above the plant like a spiky crown, with smaller purple flowers emerging in time. It's not unusual for an aechmea flower spike to last for months.

Light: Indirect light or moderate shade. Do not expose to direct sunlight, but they can be acclimated to higher light levels.Water: Keep water in the central cup. Change water frequently with clean water to prevent odor and bacteria.Temperature: Aim for 55 degrees or higher. They can survive to 45 degrees, but not for long.Soil: Any soil mix as these are technically air plants that use their roots for support.Fertilizer: Fertilize sparingly with a liquid fertilizer during the growing season.

After the flower bract dies back, cut it off at the base. New plantlets will emerge from the mother plant, which will gradually die back and can be removed at the soil level. These new plantlets can be potted up individually in small pots or left to form a clump of plants. Make sure newly potted bromeliads are well-supportedthey have a tendency to fall over as the root systems are weak at first.

Mature bromeliads should not be repotted. Smaller bromeliads can be potted into small containers until they are established, then moved into 4-inch or 6-inch pots until they flower. Be aware that a mature aechmea is a fairly top-heavy plant and will tip over in a standard plastic pot. Make sure the pot is well-weighted.

The two most common aechmea varieties include the A. chantinii, or zebra plant, and the A. fasciata, or urn plant. The zebra plant is distinguished by horizontal darker stripes across its leaves, while the urn plant has solid silver-green leaves. Other bromeliads include the A. blumenavii, which is upright and light green, and the A. "Fosters Favorite," which is a lower growing plant with reddish leaves. The A. "Blue Tango" features narrow, light green leaves with a spectacular blue flower bract. The A. "Del Mar" is a smaller blue bromeliad.

Aechmea are wonderfully uncomplicated bromeliads to grow. The most important rules to follow are to keep the central cup filled with clean water. The plants like to be potted in smallish pots with absolutely perfect drainage. The water should run right through your potting media, leaving only slightly wet compost behind. If a bromeliad is unstable in the pot, it can be staked up. Don't replant deeply as this will kill the plant. Aechmea with lighter or silvery leaves can be slowly adapted to higher light levels and might appreciate being moved to a sheltered nook on your patio in the summer.

In its plants in Passau and neighbouring Thyrnau, ZF Friedrichshafen AG has recovered around 1.75 million litres of valuable oil in the past twelve years by pressing grinding sludge in RUF briquetting presses. Adding to the environmental benefits, there are great economic advantages: The two presses have returned their investment in half a year and about two years, respectively.

ZF Friedrichshafen AG is one of the worlds largest automotive suppliers with around 230 locations in about 40 countries. In the two plants in Passau, ZF manufactures around 200,000 axles and transmissions, as well as other drive components, that are used worldwide in agricultural and construction machinery, forklifts, buses and special vehicles, for example. At their Thyrnau site, the employees produce bevel gear sets as well as spur gears, including for the companys own electric vehicle drives; in total about two million per year.

RUF briquetting systems at ZF: 100,000 hours of reliable operation Especially in the automotive industry, economic efficiency is one of the decisive success factors, along with innovation, outstanding quality and perfect reliability. With two RUF briquette presses in the Passau Plant 1 and at the Thyrnau site, the group is contributing to this and reducing its environmental impact at the same time: In nine and twelve years of operation respectively and a total of around 100,000 operating hours, the briquetting systems recovered a good 1.5 million litres in Thyrnau and in Passau around 250,000 litres of oil from grinding sludge which accrues during production. These quantities were ultimately saved when purchasing fresh oil. At current prices, this equates to a net purchase value of 2.2 million euros. Additionally, the systems make an important contribution to the conservation of resources. This is because previously a large part of these oil quantities remained in the grinding sludge and was disposed together with it.

Up to 300 tons of grinding sludge per year In Thyrnau, 35 grinding machines currently produce between 250 and 300 tons of grinding sludge per year. About half of it is made up of steel particles, which ultimately are microscopically fine steel chips, with grinding wheel abrasion and the other half is grinding oil. Until 2006, technicians used their own constructions to press out part of the oil from the sludge. However, we were nowhere near recovering the large quantities of oil that the RUF press enables, says Johann Zincker, who is in charge of environmental and energy management in the plant. This advancement in oil recovery was initiated by the RUF sales manager, Andreas Jessberger, who read about the production at the Thyrnau plant in a trade journal in 2006 and subsequently pointed out the potential of the briquetting plants to the plant management. Test pressings at the RUF headquarters in Zaisertshofen convinced the managers in Thyrnau of the benefits and in 2007 a RUF 4/2800/60S had already started operation. The machine is filled by means of forklift trucks, which dump 0.4 cubic meters of grinding sludge from each collecting container into the supply hopper of the press. The system, which is designed for unmanned operation, starts automatically as soon as there is enough material in the feed hopper and also stops automatically when the grinding sludge has been completely processed. The RUF system, driven by a four kilowatt electric motor, compresses the grinding sludge and presses out most of the oil. What remains are largely de-oiled briquettes consisting of fine metal abrasion and a small amount of residual oil.

Two-stage filtering system automatically purifies the oil The oil which runs out during the pressing process is collected and purified by means of a two-stage filtering system, which ZF designed in Thyrnau itself. For the plant in Passau, RUF integrated this filter solution directly into the briquetting system. A coarse filter retains elements larger than 160 micrometers. This is followed by a second stage, which also separates particles larger than 40 micrometers. From there, the oil flows into an IBC container, which holds one cubic meter. The full containers now remain motionless for four days, so that any remaining solids are deposited on the bottom. Following this sedimentation phase, ZF pumps out the oil from the top and returns it to the grinding machines without further treatment. The effort required for operation is minimal. In addition to filling the machine with grinding sludge, employees only replace the IBC containers full with the recycled oil, with empty ones and they cart away the collection containers with the briquettes and regularly replace the filter media. Apart from this, they clean the machine at defined intervals.

Large oil purchase savings minimal operating costs About every six weeks the system in the Thyrnau plant receives a new press piston, and once a year a thorough maintenance is due. All work is carried out by the plant's maintenance staff themselves. The piston wear is due to the relatively high selected pressing power. In this specific case, however, it pays off to increase the oil yield with high pressure and therefore change the punch more frequently. The total cost for maintenance and wear parts have been minimal and consistent ever since the machine was commissioned, twelve years ago. This saves about 1.50 euros per kilo of recovered oil. This is set against 0.18 euros of operating costs for maintenance and wear parts so around 12% of the achieved savings.

The Thyrnau plant recycles more than 120,000 litres of oil every year "By pressing with the RUF machine we recover between 100 and 120 tons of oil per year from the grinding sludge", explains Johann Zincker. Since the oil has a density of only about 0.85 g/cm3, these masses correspond to a volume of about 120 to 140 cubic meters. In addition to the reduced environmental impact through recycling instead of disposal of the oil, there are great economic benefits. At a current price per kilogram of the oil of just under 1.50 euros net, the press currently generates annual savings of between 150,000 and 175,000 euros. Furthermore, the disposal costs for the briquetted residual grinding sludge are reduced, due to the reduced amount. After the purchase in 2007, with significantly lower throughputs at that time, the press had a amortisation period of less than half a year. "With today's volumes it would take even less time", Zincker sums up and adds: "The press is simple and uncomplicated - if only all machines would run so reliably and economically" Leo Schauer, Head of Maintenance in the Steel Performance Centre of Plant 1 at the ZF site in Passau, is also completely satisfied with his briquetting press. Inspired by the good experiences with the RUF press that his colleagues at the Thyrnau plant had already had, Schauer pressed ahead with the use of a briquetting press at the Passau plant in 2010. At the start of 2011 the machine, also a RUF type 4/2800/60S, went into operation. The Passau plant produces less grinding sludge in total. This is why the machine is only in operation in three to four shifts per week. This means that it recovers about 35,000 litres of grinding oil every year, which has added up to a total of 350 cubic meters since it was commissioned in 2011. The amortisation period was therefore about two years, as Leo Schauer recounts. A somewhat different procedure for the way the oil pressed out of the machine is returned to the production process was established here. Leo Schauer and Alfred Weisheitinger, who is in charge of maintenance, dispensed with the regular sedimentation phase after the two-stage filtration, but take a sample of the recycled oil from each container for examination in the laboratory. The main reason: A few grinding machines in Passau do not work with oil. The analysis helps to rule out that a batch of emulsion sludge accidentally enters the press and contaminates the oil. Maintenance and the replacement of wear parts is also carried out by ZF employees themselves in Plant 1 in Passau. Every two years we order a spare parts package from RUF and then install the parts ourselves depending on the their wear, Leo Schauer explains. The bottom line, Schauer summarises, is that the machine is a sure-fire success. At the site in Passau the press runs three to four days per week for eight hours each. At the Thyrnau plant, on the other hand, the press even runs 24 hours a day, five to six days a week. And it does this extremely reliably We have not experienced any serious disruptions since commissioning," Johann Zincker reports.
