Indoor Plants Or Houseplants
Visit us on the Web: www.gardeninghelp.org Indoor Plants or Houseplants Over the past twenty years houseplants have grown in popularity. Offered in a wide variety of sizes, shapes, colors and textures, houseplants beautify our homes and help soften our environment. They have been scientifically proven to improve our health by lowering blood pressure and removing pollutants from the air we breathe. When selecting a houseplant, choose reputable suppliers who specialize in growing houseplants. Get off to a good start by thoroughly examining each plant. Watch for brown edges and spindly growth with elongated stems and large gaps between new leaves. Inspect leaves and stem junctions for signs of insect or disease problems. Check any support stakes to make sure they are not hiding broken stems or branches. Finally, make sure the plant is placed in an area that suits its optimal requirements for light, temperature and humidity. Where to Place Your House Plants With the exception of the very darkest areas, you can always find a houseplant with growth requirements to match the environmental conditions in your home. The most important factors are light intensity and duration. The best way to determine the intensity of light at a window exposure area is to measure it with a light meter. A light meter measures light in units called foot-candles. One foot-candle is the amount of light from a candle spread over a square foot of surface area. Plants that prefer low light may produce dull, lifeless-looking leaves when exposed to bright light. Bright light can also cause leaf spots or brown-tipped scorched margins. -

Houseplant Cuttings
Houseplant Cuttings Rooting plant cuttings is an easy way to increase your collection quick- ly, and to teach about vegetative propagation. Many common house- plants root nicely in a light garden or on a windowsill. You can repot these new plants for your classroom or send them home with the chil- dren. Here’s a list of houseplants we recommend for this purpose. Stem Cuttings Leaf Cuttings Plantlets impatiens snake plant aloe coleus jade plant spider plant chrysanthemum begonia piggyback plant African violet African violet geranium philodendron wandering jew Swedish ivy How to Root Cuttings 1. Water plants well the day before taking cuttings. This reduces dehydration after cutting. 2. You can root many cuttings in one container to save space and soilless mix. Repot them once the cuttings have rooted. Use your soilless mix (or a mixture made from equal volumes of perlite and vermiculite) as a rooting medium. Make sure the mix is moist, but not soaking wet, or your cuttings will rot. 3. Fill the container with mix, gently firm it in place, and make small holes (1/2 inch to 1 inch deep) with your finger or pencil, spaced as close as 2 inches apart. 4. Next, take cuttings as described below. Be sure to hold a cutting by the leaf, not by the stem. If a leaf is damaged, a new one can grow, but a damaged stem can kill a plant. Stem cuttings — Take cuttings from newer, faster-growing stems by snipping with scissors just below the third or fourth pair of leaves. Strip off the lower pair of leaves (roots will prob- ably grow from here) leaving two to three sets of healthy leaves above (see figure A). -

Forcing Bulbs “Forcing” – Coaxing, Actually – Is the Term Used To
Forcing Bulbs “Forcing” – coaxing, actually – is the term used to describe the process that stimulates bulbs to bloom out of season. Among the most commonly forced bulb flowers are amaryllis, paper white narcissus, muscari, and hyacinths. Certainly they are the easiest! When selecting bulbs for forcing, look for varieties that are specifically recommended. Spring flowering bulbs usually require a rooting period of about 12 to 15 weeks at temperatures between 41 to 48°F in order to produce a good root system; which is essential if they are to be “forced” into flowering. Storing Bulbs Bare bulbs can be stored for several weeks in your refrigerator prior to potting without damage if they are packed properly. The best way to store them is in a mesh bag or paper bag with holes that permit ventilation. You don’t have to worry about water, as the humidity inside a refrigerator is usually high enough. Check them periodically to make sure they are not molding or drying out. Pot your bulbs right away if you have an appropriate location immediately available, such as an old (functioning) refrigerator, a root cellar or cool basement – or if outdoor temperatures are below 45°F. If, however, your area experiences an “Indian Summer’, your fridge can serve as a suitable rooting area. Vegetable or crisper drawers can be used, but don’t store bulbs in the same drawer you keep ripening fruit or vegetables – these give off ethylene gas which can harm the bulbs. (Also some bulbs are poisonous, so make sure to keep them out of reach of children). -
Five Houseplant Trends Nicole Sanchez October 2019 “What's Old
Five Houseplant Trends Nicole Sanchez October 2019 “What’s old is new again”, horticulture edition: houseplants and all that accompany them- from foliage prints to macramé hangers- are figuring prominently in nursery and garden center trade magazines. Likewise, houseplants are frequent focal points in home décor and furnishing vignettes. Last time macramé plant hangers were popular, the houseplants found within them were mostly pothos, spider plants, snake plants, and anything in a terrarium. This time around, the variety and affordability of once- exotic plants make indoor gardening increasingly budget friendly. Enhancements- lights, hydroponic systems, media and hormones for propagation- are now widely available, and provide opportunity for serious enthusiasts. For some blooming plants, artificial light on a timer can be useful for providing the day length needed to induce bloom. One reason houseplants are currently surging in popularity is their association with a more positive environment or energy. While “positive energy” is not a measure science can quantify, people report feeling better when they spend more time in environments that are rich with plant material. A search of popular web- based shopping sites reveals that houseplants for sale online are promoted as “air purifying” and “mood lifting”. Now that the outdoor growing season is over in the Klamath Basin, it’s a perfect time to consider incorporating some houseplants into your indoor space. Following, are some tips for groups of plants that are currently trendy in horticulture. Locally, the Master Gardeners will be offering a selection of houseplants for sale October 25 and 26 at KBREC (see side box). Orchids. -

African Violet, a Favorite Houseplant by Susan Camp Cats Like to Eat
African Violet, a Favorite Houseplant By Susan Camp Cats like to eat houseplants. We had Bilbo, who devoured the Christmas cactus every year and one Christmas, a Poinsettia leaf, necessitating a trip to the emergency vet clinic. Sophie Bean regularly snacked on our venerable ficus, but it survived her pruning and has thrived for 27 years. Roy enjoyed munching on an ancient clerodendron, but the worst plant destroyer is M Shaddow, who joined our household in 2013, and within three months, systematically destroyed five African violets that I had nurtured and protected since 2004. The African violet (Saintpaulia spp.) was discovered in Tanganyika (Tanzania) by Baron von Saint Paul, Governor-General of German East Africa, and sent to Europe in 1892, where it soon developed popularity as a houseplant. The pretty African violet, with its white, purple, blue, or pink flowers and fuzzy, dark green leaves, is not a true violet, but belongs to the Gesneriad family, along with gloxinia and lipstick plant. Most of the hundreds of cultivars on the market today have been hybridized from the two original species, S. ionantha and S. confusa. African violets grow well in the household environment, although they require a little extra attention and care to show off their succulent leaves and fleshy, candy-colored blossoms. African violets grow best in a north or east location, requiring 1000 foot-candles of light for 8 to 12 hours each day. Too little light will decrease flowering and cause leaves to thin and darken. Pale or yellowish-green leaves occur with excessive light. In the absence of sufficient natural light, fluorescent light at 600 foot-candles for 12 to 16 hours each day will foster healthy leaves and blooms. -
Floraguard: Tackling the Illegal Trade in Endangered Plants In
FloraGuard Tackling the illegal trade in endangered plants Foreword 1 Foreword The word poaching may not be readily associated with plants, yet illegal collection from the wild poses a direct threat to many of the world’s most iconic plant species such as orchids, cacti and cycads. In recent decades, the trade in illegal live specimens, along with other plant products, has spilled onto the internet, providing illegal traders with a means of reaching a global consumer base, while remaining cloaked in the anonymity and vast scale of cyberspace. Yet the adopting of online technology by wildlife traffickers also presents opportunities to map, understand and counteract this trade. The recent global report from the Intergovernmental Science- Policy Platform on Biodiversity and Ecosystem Services (IPBES) identified that direct exploitation of organisms – in which illegal wildlife trade plays a central role – is one of the most impactful drivers of change in nature, second only to changes in land and sea use. Species exploitation is even more damaging to biodiversity than climate change. Safeguarding the natural world against this threat requires innovative approaches and effective collaborations. Led by the University of Southampton and partnered with UK Border Force and the Royal Botanic Gardens, Kew, the FloraGuard study took a new approach to meeting this challenge. The study’s findings encompass insights into the criminological mindset of plant traffickers, the use of botanical expertise to identify suspicious online posts and the potential application of cutting-edge artificial intelligence techniques. This level of cross-disciplinarity illustrates the range of expertise involved in the project and the scope for further innovation that exists within the field of online trade enforcement.
