This is both fast and accurate, producing an exact replica of the original plant. Starting Lavender from ** seeds** sounds like a great inexpensive way to get all the lavender you desire but it can have some major drawbacks. The first obstacle is finding the seeds. Even though Spanish, Yellow, and other species Lavenders can be started from seeds, it is usually only the Lavandula angustifolias--Hidcote, Vera, and Munstead-- that are available as seeds. The second drawback is what we call 'low and slow' germination. Lavender seeds have a short shelf life, and therefore the germination rate (how many seeds out of 100 come up) is usually pretty low. They can also take a long time to sprout (two weeks or more) and this invites fungus to the seed tray, often causing the seed to rot before it can sprout. Seeds benefit from light, so cover lightly when sowing. The germination temperature should be around 70 degrees and spring seeding is more successful than fall seeding. Those seeds that do sprout will take one to three months before they have enough roots and top growth to allow successful transplanting. Adding fertilizer to the sterile medium used in the seed tray can help the little plants get off to a better start, but it can also invite fungus in cool, humid situations. The third disadvantage is the time it takes for the seedlings to get to a good size. After they are transplanted into small pots, the plants will be about three inches tall and have a single stem. It will take another three months or more to make a plant substantial enough to transplant to a larger pot or to the garden. The fourth inconvenience is the difference factor. Because little care has been taken over the years to insure that the seeds have not crossed with each other, the plants will be varying shades of color. They might also vary some in height and width. This was the surprise our customer had. The perfect hedge of Hidcote Lavender she had dreamed about and worked so hard to grow the plants for turned out to be more like a cottage garden: still beautiful, but irregular in form and color. And, lastly, the most popular Lavenders (the Lavandula x intermedias; sometimes called Lavandins), either do not make seeds or the seeds are sterile, so you will never see a seed packet of these. The most important factor to get right with Lavender is drainage. Soggy areas should definitely be avoided. Incorporate organic matter if necessary to make a loose friable soil. Compost is the best amendment because it is fertile and has uneven particle sizes. Uneven particles in the soil create better air spaces and give the roots better anchors to attach themselves to. Check the soil's pH (potential hydrogen) to make sure it falls somewhere between 6.5 and 7.5. If the soil is too acidic the Lavender will not thrive. If the soil is too alkaline, the nutrients are 'tied' up in the soil and the plant cannot use them. Yellowed growth can be indicative of a soil that is out of balance. Adding compost can help to balance the pH. If you are going to plant a hedge or a massive amount of Lavender, make sure the ground is cleared of** weeds**. ** Solarization** works to remove not only tenacious weeds, but also kills weed seeds. Small Lavender plants cannot compete with aggressive weeds, and weeding after they are planted can be a huge hassle. Weeding often becomes such a chore that Lavenders are overrun and eventually die in a neglected field. Mulching with a small particle mulch or compost after planting helps with the weed control, but avoid mulching right up to the stem of the small plant. Instead, leave a collar about two inches wide around the plant. If you are in hot, humid areas, try planting Lavenders in a raised bed or on a mound. Leave plenty of room between plants for air circulation. Lavenders are not ideally suited to heat and humidity, so be prepared for problems, such as fungal disease and rot. For ultimate show, space plants according to their height measurement. For example, a Grappenhall Lavender is listed at 3 to 4 feet. By spacing these 3 or 4 feet apart, the effect when the plant is blooming is spectacular. If it is more important that the plant make a tight row or hedge, then plant closer together. If planting in pots, make sure to repot every spring into a larger container with fresh soil to allow the plant to continue to mature and to provide as many flowers as possible. A good, coarse, sterile ** potting soil with organic fertilizer mixed in works best. In the ground or in a pot, full ** sun is a must. If the garden is crowded, plant near a south-facing wall. Even the Lavender at the north end of the row will be shorter and bloom later. In hot areas, some late afternoon shade can be tolerated without sacrificing the glorious mounded shape and rising pincushion effect of the flower wands. Lavender in the field rarely needs fertilizer, especially if compost is applied as a mulch. More often, problems arise because the soil is not healthy. Avoid chemicals in pesticides, herbicides, and fertilizers that kill or starve the beneficial organisms in the soil. In arid regions with no summer ** water,** irrigation will be necessary for the survival of the plants. While Lavender is extremely drought resistant once established, it grows larger and produces more blooms with regular watering. This means that when it is dry, water it. While this may sound obvious, it is important to let it dry out a bit before soaking it again. In humid areas, this can be difficult and the excess moisture often causes death. The Gardener's Minute Zones 8 and up can plant Lavender in spring and fall, but other zones are better off with a spring planting after the last frost. If fall planting is to be tried, plant at least two months before the first frost. It is important that the plant actually make good root development into the native soil before severe winter weather occurs. Lavender grows slowly in the fall and often plants are not sufficiently established to get through winter rains and cold. It takes about three years for a Lavender to reach full size. Plants should be pruned every year immediately after bloom. ** Pruning ** should not be confused with harvesting. Pruning is necessary to extend the life of the plant. Lavender flower wand stems are usually a bright green while Lavender leaves are gray. Cut back not only the flower stem, but also about a third of the gray-leaved stems as well. If the plant has been neglected, it can be cut back further, but avoid pruning back so far that only woody stems with no leaves are showing. A plant pruned into the wood may push out latent (sleeping) buds or it may die. Harvesting ** Lavender is one of the most enjoyable pleasures any gardener can have. Lavender flower heads look gray before the flowers open. They are devoid of most color and it is easy to become impatient waiting for them to burst into bloom. Once the color is bright and vivid, that is the time to start cutting. Cut the flower stems during the cool of the morning after the dew has dried. In humid areas, try to cut on dry days. For arrangements, it is easiest to arrange the Lavender while it is fresh and supple. This can be done in the garden if it is not too hot. If the weather is very warm (even in the morning), take a bucket of water, filled about a quarter of the way, and submerge the cut end of the stems into the bucket. Remember that the plant cools itself by releasing its fragrant oils, so the more heat they are exposed to the less oil, and fragrance, for you. Arrange out of direct sun as soon as possible. Stand them in a dry vase and the fresh flowers become dry ones. Or use fresh in small groups as an accent for a fresh herbal wreath. If the flowers are to be used later, dry in small groups by tying with a twist tie and hanging in a dark dry place or individually by spreading them on a screen and drying out of the sun. Once dry, the buds can also be stripped and used as bulk for potpourri, sachet, or even cooking. Some Lavenders hold their buds better than others. Grosso Lavender is preferred for wand making and dried arrangements because the flowers stay on the stem better. This is something to consider if your primary focus is to REMOVE the dried buds for bulk use, such as potpourri. Provence Lavender** is more suited to this because the buds release easily from the calyx (too * easily for dried bouquets or wands). The further along in the bloom cycle, the more fragile the flowers seem to be. Actually, what happens is that the little flowers fall out and what is left is the calyx and any unopened buds. Most Lavenders bloom for about 5 weeks, so do a little experiment in your garden to see when the harvest is best for your needs. If you are harvesting a lot of Lavender, try this tip from the Lavender experts at Purple Mountain Majesty. Hand harvest by sticking your left thumb in the flowers to be cut while simultaneously hooking the flower stalks in front and below your left hand with a Chinese sickle. You pull and cut the first bunch into your left hand with one motion. The process is repeated without removing the cut material until you have completely cut counterclockwise around the plant essentially twisting the cut stalks around the center uncut stalks as you go. This keeps even the largest bundles under control because the whole bundle winds around the center uncut stalks creating enough friction to keep everything together and eventually captured under your left arm. If the bundle is too big for your grip, then it is kept from falling apart by your thumb and the center stalks, which you cut in a final cutting motion starting with a reversed sickle in front of your left leg and vectoring in a direction that is away from the harvester. Lavender smells like it should taste wonderful, but the taste of most Lavenders is a little like turpentine. The flavor is not one that can be easily defined nor is it one most people like right away. It is like a fine wine with many subtleties. Both fresh and dried flowers and leaves are used in ** culinary preparations*. Recipes using Lavender are generally on the sweet side but Lavender can be used to replace Rosemary and other strong tasting herbs. Or, it can be blended with other herbs, as in herbs de Provence. This mix, used in many ** savory dishes**, often finds dried Lavender leaves and flowers mixed with other members of the mint family, like Rosemary, Sage, Oregano, Thyme and Mint. Used not only to make life smell richer and more tolerable, but also as a ** medicinal relief** for ailments from headaches to insomnia, Lavender oil has always been a prize. In times past, most Lavender oil was distilled from the angustifolia species of Lavandula. Often referred to as English Lavenders, these Lavenders are native to the western half of the Mediterranean. Now cultivated in many countries, it was thought the finest Lavender grew in England and thus the common name English Lavender evolved and is still the name most folks use when referring to Lavender products. Because Lavandula angustifolias are small, and because they are pretty particular about where they grow, it takes a lot of plants to produce one ton of oil; so most Lavender oil now comes from the Lavandins. These are hybrid Lavenders that have the English Lavender as one parent and the Spike Lavender (Lavandula latifolia) as another. These Lavenders tolerate a more diverse climate, and, since they are larger, produce more oil per acre. This oil, while less expensive, is not as good for medicinal purposes as English Lavender oil, but it is widely used in the perfume and craft industries. And, when you hear the term French Lavender Oil, don't be confused. The French nom de plume refers to where it is grown and not which plant it is from. French Lavender oil is really English Lavender oil produced in France! http://www.mountainvalleygrowers.com/lavendercareandtips.htm P/S: đây là loại hoa mới đang nghiên cứu, mở rộng và phát triển tại Việt Nam nên tài liệu cũng rất hạn chế.
