This 2020 year we hope to continue to educate and inspire your garden dreams and needs. We decided this year we would focus an educational article on a houseplant each issue. We have also heard from many that you would like more house plants at our bi-annual sale at the Renville County Fair, which will be this August Thursday 6th- Saturday 8th. So, we will have more house plants, but also many outdoor perennials. If you have friends that would like to join our newsletter, email their email address to us at [email protected] and we would love to add them to our list. Thank you again for being a reader of our newsletter. Renville County Master Gardeners February Garden Tips • Inventory and clean tools. Use a wire brush to remove excess soil. Follow this with steel wool to remove any rust that formed on metal surfaces. Sharpen the soil cutting edge of trowels and shovels with a triangular file. Rub in a couple of drops of oil to prevent further rusting. • Visit home and garden shows to get new ideas. The professionals at these shows can give you terrific design and planting tips. Or check out landscape books at the library for ideas and pictures. • Start finalizing your garden plan. List the vegetables your family likes to eat, and remember to include the ingredients for your favorite recipes. Visit a local garden center and see if they have the seeds you need to start indoors. Order any unusual or hard-to-find seeds from a reliable company. • Trees can be pruned during the dormant season, when it is much easier to see the overall shape of the tree and what needs to be removed. Prune oaks in winter to reduce risk of oak wilt. • Beat the spring rush and have your lawn mower serviced now. • It is the time to start impatiens, petunias, wax begonias, pansies and gerbera daisies. They should be started by mid-February. If in doubt when to start, check the planting dates on the seed packets or catalogs.

Short days and long nights, low relative humidity and cold drafts can be stressful to many houseplants. Good consistent care should keep them healthy and attractive How often should I water houseplants in winter? In general, houseplants require less frequent watering during the winter months than in spring and summer. Watering frequency depends upon the plant species, composition of the potting mix, environmental conditions (temperature, light and humidity) in the home and other factors. When watering houseplants, continue to apply water until water begins to flow out the bottoms of the pots. Discard the excess water. Should houseplants be fertilized in winter? Fertilization is generally not necessary during the winter months as most houseplants are not growing during this time. Indoor gardeners should fertilize their houseplants on a regular basis in spring and summer when plants are actively growing. How can I raise the relative humidity indoors for my houseplants? Many houseplants prefer a relative humidity of 40% to 50%. Unfortunately, the humidity level in many homes during the winter months may be only 10% to 20%. Humidifiers are an excellent way to increase the relative humidity in the home. Simple cultural practices can also increase the relative humidity around houseplants. Grouping plants together is an easy way to raise the humidity level. The water evaporating from the potting soil, plus water lost by plant foliage via transpiration, increases the relative humidity in the vicinity of the houseplants. Another method is to place houseplants on trays (saucers) filled with pea gravel or pebbles. Add water to the trays, but keep the bottoms of the pots above the water level. The evaporation of water from the trays increases the relative humidity around the plants. What are proper indoor temperatures for houseplants in winter? Most houseplants prefer daytime temperatures of 65 to 75 degrees Fahrenheit and night temperatures of 60 to 65F. (In winter, day and night temperatures in the lower range of the aforementioned temperatures are fine for most houseplants.) Temperatures below 55F or rapid temperature fluctuations may harm some plants. In winter, keep houseplants away from cold drafts and heat sources (such as fireplaces, furnace vents and radiators). Also, make sure houseplant foliage doesn’t touch cold windows. Source: Iowa State University 3 Smart Gardening in 2020: Choose plants with more than one purpose Quick Fire® hydrangea. Photo: PovenWinners.com Winter came early this year with lots of snow and cold temps, but it's never too early to start thinking about new plants for your garden and yard. Maybe you've had a shrub that has not lived up to expectations and you are ready to replace it. Or you have lost a tree lately and suddenly have a large sunny spot for planting. Got a fence that needs screening? A vine is a good option. Regent serviceberry Whatever your reason, a smart gardening good goal for 2020 is to choose plants that serve more than one purpose. Here are some favorite multi- purpose plants in my yard: The Regent serviceberry shrub (Amelanchier alnifolia 'Regent') has lovely white flowers, edible fruit and provides pollen and nectar for bees. Multi-purpose Grasses Grasses can create waves of texture and show off other plants. Some, like our native prairie dropseed (Sporobolus heterolepis) and blue grama (Bouteloua gracilis), also provide food for butterfly larvae. Sedges (Carex spp.) can be planted under taller plants to reduce weeds and serve as a growing mulch. Beatlemania sedge The flowers of one of my favorite plants, Quick Fire hydrangea (Hydrangea paniculata 'Bulk'), turn a deep mauve in late fall, and can be cut and added dried to floral or container arrangements in the winter. 4 Flowers good enough to eat! Edible pot marigold flowers (Calendula spp.) provide pollinator food, bloom well into fall and the petals can be sprinkled on salads for a citrusy bite. Bee-friendly vines Vines like the new self-fertile bittersweet Autumn Revolution (Celastrus scandens 'Bailumn' PP19811) serves as food Calendula flowers for birds and pollinators and can be cut and twisted into decorative vines. Unlike Oriental bittersweet, it is not invasive. In 2020, resolve to choose plants for more than just their good looks as they can serve multiple purposes in your yard and garden!

Poinsettias with a variety of colors and patterns. “How can I make my poinsettia rebloom?” is a common question we hear in January. Poinsettias can be grown as attractive green plants, but most people are interested in making their green poinsettia colorful again and ready for the holidays. Can I make my poinsettia re-bloom? It is not an easy task, as it requires excluding light from the plant for a period of time while keeping the plant healthy. The reduction in light prevents the plant from producing chlorophyll, the pigment that makes plant parts green. This changes the bracts to red, pink or white, depending on the poinsettia variety. An E-Z to follow system of care Dr. Leonard Perry, Extension professor emeritus at the University of Vermont and author of Caring for Your Poinsettia Year-Round, developed an easy-to-follow poinsettia care calendar based on the holidays of the year!

American Samoa, trees dripping with Hoyas 1 A pdf publication devoted to the Genus Hoya ISSN 2329-7336 Volume 2 Issue 4 July 2014 Editor: Dale Kloppenburg Contents When a species is collected from the wild, I feel it is wise to identify it, propagate it and name it. In this way it will eventually get it into commercial channels, be distributed to all those interested in this genus and thus be preserved. If in the future the species is lost through natural causes or forest destruction it will still be here on earth in your collection. Corrections: Vol. 2 – 2 May 2014, Katherine Challis at IPNI has pointed out that “stemma” is a singular neuter III so the endings on the two following Eriostemma species should be (corrected) as follows.

  • Hoya Australis Subsp. Oramicola (A Vine)
    Advice to the Minister for the Environment and Heritage from the Threatened Species Scientific Committee on Amendments to the list of Threatened Species under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Scientific name (common name) Hoya australis subsp. oramicola (a vine) 2. Description Hoya australis subsp. oramicola is an evergreen, perennial vine with succulent leaves that grow to approximately 10cm long. Its flowers are cream coloured and fleshy, with flowering recorded during March and July. Fruiting occurs three to four months after flowering. 3. National Context Hoya australis subsp. oramicola is endemic to the Northern Territory. The subspecies is restricted to coastal monsoon vine thicket communities on Bathurst and Melville Islands, where it is known from four localities (Kerrigan et al 2004). The subspecies is currently listed as vulnerable under the Northern Territory Territory Parks and Wildlife Conservation Act 2000. 4. How judged by the Committee in relation to the EPBC Act criteria. The Committee judges the subspecies to be eligible for listing as vulnerable under the EPBC Act. The justification against the criteria is as follows: Criterion 1 – It has undergone, is suspected to have undergone or is likely to undergo in the immediate future a very severe, severe or substantial reduction in numbers. Hoya australis subsp. oramicola is endemic to the Northern Territory. The subspecies is restricted to coastal monsoon vine thicket communities on Bathurst and Melville Islands, where it is known from four localities (Kerrigan et al 2004). Very little data on abundance is available for this subspecies. Russell-Smith (1992) records this subspecies as common at Lubra Point on Bathurst Island and uncommon at Condor Point on Melville Island.

  • Life Cycle Cost of Air Plant Green Roofs in Hot and Humid Climate
    I J A B E R, Vol. 14, No. 10 (2016):Life 7167-7182 Cycle Cost of Air Plant Green Roofs in Hot and Humid Climate l 7167 LIFE CYCLE COST OF AIR PLANT GREEN ROOFS IN HOT AND HUMID CLIMATE Tachaya Sangkakool* and Kuaanan Techato2* Abstract: The benefitsof green roofshave beenrecognizedby many researchers worldwide.Green roofs have been wildly implemented in many countries due to the trend of green architecture, sustainable architecture and environmental friendly concept. The computational life cycle cost of air plant green roofs is classified into two parts. One is the initial investment, which compos- es of the cost of materials and installation process. Another is the cost of operation and main- tenance. This paper has investigated in the economics of green roofs by reviewing secondary data of extensive green roof and intensive green roofs and collecting experimental data of air plant green roofs. The investigation of life cycle cost of “Cotton Candy” air plant green roofs is around 140.21$/m2 and “Spanish moss” air plant green roofs is around 125.78 $/m2. Although the digit is lower than other types of green roofs, the benefit is almost the same. It was found from the research that life cycle cost of air plant green roof is less than other types of green roof. However, the benefits are not different from other type of the roof. Another strengthof air plant green roofs is shading to the roof of the building. These will extend the life cycle of the roof. The consideration of life cycle cost of air plant green roofs will be another tool using in making final decision.

Wheat pasture is succu- lent, palatable and nutritious. However, wheat pasture is typically low in calcium, marginal to sufficient in phosphorus and magnesi- um, and contains excess potassium for 400 to 600 lb stocker calves. It is also typically low in the trace minerals, copper and zinc. Due to these deficiencies, mineral supplementation on wheat pasture is highly recommended. Calcium is the macro-mineral of pri- mary concern in most wheat pasture-grazing situations. Two conditions which may occur with grazing of wheat pasture are wheat pasture poisoning (grass tetany) and frothy bloat. Wheat pasture poisoning is a complex metabolic disorder of cows grazing on wheat pasture. It occurs most frequently in mature cows that are in the latter stages of pregnancy or are nursing calves, and that have been grazing wheat pasture for 60 days or more. It results from a dietary deficiency of magnesium or from the presence of some factor in the diet which reduces absorption and/or utilization of magnesium.

Individuals were examined within the canopies of host trees in open, exposed situations, as well as in dense forests. Although night time CO2 concentrations were higher near the epiphytic vines at night, relative to those measured during the day, presumably the result of CO2 added to the canopy air by the host tree, no evidence for substantial use of this CO2 was found. In particular, stable carbon isotope ratios of H. carnosa were not substantially lower than those of many other CAM plants, as would be expected if host-respired CO2 were an important source of CO2 for these CAM epiphytes.
