i-Tree - Tools for Assessing and Managing Community Forests Ziziphus spina-christi Ziziphus spina-christi, the Christ's Thorn Jujube is an evergreen tree native to northern and tropical Africa and southern and Western Asia. It grows in Israel in valleys up to an elevation of 500m. Ziziphus spina-christi has significance to Jews, Christians and Muslims, and is by some traditions the tree from which Jesus's Crown of Thorns was made. The ripe fruits are edible and the flowers are an important source of honey in Eritrea and Yemen. References Ziziphus spina-christi in West African plants – A Photo Guide. Other links
UK - National Fruit Collection Fruit Identification Outline a. Achene: Very small, one-seeded fruit, usually produced in clusters. At maturity the pericarp is dry and free from the internal seed, except at the placental attachment. This is the typical fruit of the largest plant family, the sunflower family (Compositae or Asteraceae). Examples of this type of fruit include the sunflower (Helianthus), buttercup (Ranunculus) and sycamore (Platanus). b. c. d. One of the most painful schizocarps is the puncture vine (Tribulus terrestris). e. f. g. Note: Wayne's Word contains a lot of additional information about the remarkable duckweed family (Lemnaceae), the undisputed world's smallest flowering plants.
Fences Of Fruit Trees - Espalier Method We visited a 200-year-old walled garden yesterday in County Offaly, a vast area of infrastructure exquisitely crafted to feed whole communities. The paths through the gardens were flanked with what appeared to be wooden fences covered in leafy vines. One closer inspection, they were not vines, but apple trees. The branches were thin but heavy with what my daughter calls “applings.” Near them stood similar trees perhaps a century old, their gnarled trunks supporting immense candelabras several metres across. Almost anyone who has a backyard or garden would do well to plant fruit trees for the years ahead. Espalier is a method of growing a dwarf fruit tree along a wall or fence, binding it for support, and bending the branches to follow certain lines, as Japanese artists do with bonsai trees. Apples seem the most common espalier tree, and pears were also common here when this practice was widely used – many varieties of each can be used, some more easily than others.
Dutch Study Says Wi-Fi Makes Trees Sick A recent study by Dutch scientists found that Wi-Fi radiation could be responsible for sickness in urban-populated trees. Image: baltimoresun What would life be like without Wi-Fi, bringer of high speed internet access? Probably pretty inconvenient considering that millions of computer users around the world use it at home, at work and other public places to get online. Having access to wireless networks makes our lives easier, but according to a Dutch study from Wageningen University, this access may be compromising the health of trees. The study began five years ago in the city of Alphen aan den Rijn. According to an article from PC World : “The study exposed 20 ash trees to various radiation sources for a period of three months.

Pir-e Herisht. Abarkuh. Pilgrimage in Zoroastrianism Suggested prior reading: » Yazd Region Associated reading: » Udvada » Zoroastrian Places of Worship - Atash Bahrams The first part of the directions to Pir-e Herisht are the same as that for Pir-e Sabz. Pir-e Herisht is dedicated to the royal Yazdegird governess Morvarid (also spelt Murvarid). It was a passing traveller who built the first shrine. While not a pir, the Cypress of Abarkuh is nevertheless a quasi-pilgrimage destination. Abarku is home to a 4,500 year old cypress (Persian, sarv) tree that stands some 25 metres tall. For Zoroastrians, the cypress (Persian, sarv) is rich with symbolism. The tree and its park are next to a mosque which built over a Zoroastrian chahar-taqi temple. On the outskirts of the city are the ruins of an old caravanserai, a testament to Abarku once being a rest-stop on a branch of the ancient Aryan trade roads, also called the Silk Roads. » Top Pilgrimage pages: » Pilgrimage start page » Pir-e Sabz / Chak-Chak » Seti Pir. » Pir-e Banu. » Pir-e Herisht.
Planting Distance For Fruit Trees & Berries Apples (Standard) - 30 to 40 feet apart each way Pears (Standard) - 16 to 40 feet apart each way Pears (Dwarf) -10 feet apart each way Cherries (Standard) - 18 to 20 feet apart each way Plums (Standard) - 16 to 20 feet apart each way Peaches - 16 to 18 feet apart each way Apricots - 16 to 18 feet apart each way Currants - 3 to 4 feet apart each way Gooseberries - 3 to 4 feet apart each way Raspberries - 3 to 5 feet apart each way Grapes - 8 to 12 feet apart each way To estimate the number of plants or trees required for an acre, at any given distance, multiply the distance between the rows by the distance between the plants, which will give the number of square feet allotted to each plant, and divide the number of square feet in an acre (43,560) by this number. The result will be the number of plants or trees required. Submitted by KP, WA [Home] [Search]
Society of American Foresters How To Harvest & Store Herbs Most herbs for culinary use are ready to harvest just before flowers appear on the plant. If you harvest them after the flowers appear there will be a reduction in flavor. Do not cut the herbs too close to the ground, if you leave some lower foliage you may be able to get several cuttings during the growing season. The best time of day to harvest herbs is in the early morning, just as the sun dries the dew from the leaves. The oils are the strongest in the plants at this time. The most common method of drying herbs is also the most picturesque. A variation of this would be to put each bunch in a perforated paper bag, then hang it up to dry. Another variation of air drying is to take the herb plants apart and spread those parts on screens to dry. The fastest drying method is oven-drying. Store your dried herbs in an air-tight container, such as a glass jar. The flavoring strength of a dried herb declines with time and exposure to air and light. Submitted by KP, WA [Home] [Search]
Global Justice Ecology Project: GlobalJusticeEcology.org , Hinesburg, VT Israeli biotech firm says its modified eucalyptus trees can displace the fossil fuel industry by John Vidal, environment editor, The Guardian, Thursday 15 November 2012 GM eucalyptus trees at five-and-a-half years old, grown in a field trial. FutureGene claims GM species grow thicker and faster than the natural plant, making it possible to be grown for energy generation.It's a timber company's dream but a horrific industrial vision for others: massive plantations of densely planted GM eucalyptus trees stretching across Brazil, South Africa, Indonesia and China, engineered to grow 40% faster for use as paper, as pellets for power stations and as fuel for cars. The prospect is close, says Stanley Hirsch, chief executive of the Israeli biotech company FuturaGene. Hirsch claims the gene-altering technique is an industrial "game-changer" and integral to the UN's vision of a future "global green economy". "Our trees grow faster and thicker. FuturaGene is no small start up company.
