Which bulbs to choose? Obviously, the first thing to do is buy bulbs. But which kinds? Generally, bulbs are rated for early, mid-season or late bloom. Around Durango, “early” is March. “Mid- season” is April and “late” is May. (See box at right.)

    BIOLOGY AND CONTROL OF STEM AND ROOT KNOT NEMATODES r Becky B. Westerdahl1 Abstract: Plant parasitic nematodes are nonsegmented-microscopic roundworms which are frequently present in alfalfa fields. Although more than 10 different genera have been found in alfalfa fields in California, two (stem and bulb, and root knot) are most commonly associated with damage. A management plan to fit a particular growing situation should be developed using a combination of techniques including: planting site selection, certified seed, clean equipment, weed and irrigation management, resistant varieties, crop rotation, fallow, organic amendments and chemical nematicides. Ke~words nematode, Ditylenchus, stem and bulb, Meloidogyne, root knot, INTRODUCTION Plant parasitic nematodes are nonsegmented-microscopic roundworms which are frequently present in alfalfa fields. Whether or not alfalfa is to be planted in a nematode infested area, a grower should be knowledgeable about nematodes. If nematodes are present, both pre and postplant management strategies should be developed for pathogenic species. If an alfalfa field or a potential planting site is not infested, a grower should be aware of techniques available to prevent the introduction of harmful species. For growers to carry on a nematode pest management program they need to be familiar with (1) nematode biology; (2) symptoms and signs of nematode f damage; (3) how nematodes injure plants; (4) how to sample for nematodes; and (5) the principles underlying various management techniques including: planting site selection, the use of certified seed, the importance of using clean equipment and irrigation water, weed management, the use of resistant varieties, crop rotation, fallow, organic amendments, and chemical nematicides.

    Interspecific Breeding for Warm-Winter Tolerance in Tulipa gesneriana L. Tyler Schmidt, Plant Science Major, Department oF Horticultural Science 19 December 2015 EXECUTIVE SUMMARY Focus on breeding of Tulipa gesneriana has largely concentrated on appearance. Through interspecific breeding with more warm-tolerant species, tolerance of warm winters could be introduced into the species, decreasing dormancy requirements and expanding the range of tulips southward. Additionally, long-lasting foliage can be favored in breeding to allow plants to store more energy for daughter bulbs. Continued virus and fungal resistance breeding will decrease infection. Primary benefits are for gardeners and landscapers who, under the current planting schedule, are planting tulip bulbs annually, wasting money. Producers benefit from this by reducing cooling times, saving energy, greenhouse space, and tulip bulbs lost to diseases in coolers. UNIVERSITY OF MINNESOTA AQUAPONICS: REPORT TITLE 1 I. INTRODUCTION A. Study species Tulips (Tulip gesneriana L.) are one of the most historically significant and well-known horticultural crops in the world. Since entering Europe via Constantinople in the mid-sixteenth century, the Dutch tulip market became one of the first “economic bubbles” of modern civilization, creating and destroying fortunes in four brief years (Lesnaw and Ghabrial, 2000). Since this time, tulips have remained extremely popular as more improved cultivars are released. However, a problem remains: even though viral resistance and long-lasting cultivars are introduced, few are capable of surviving in a climate with truly mild winters and only select cultivars are able to store enough energy for another year of flowering, even in climates with colder winters. Current planting schemes suggest planting annually, wasting tulip bulbs (Dickey, 1954).

  • Bulbs: Culture and Maintenance by Diane Relf and Elizabeth Ball, Revised by Joyce Latimer, Virginia Cooperative Extension
    GARDENING FACT SHEET Harris County Cooperative Extension 3033 Bear Creek Drive, Houston, Texas 77084 281.855.5600 • http://harris-tx.tamu.edu/hort Bulbs Culture and Maintenance Originally published in the Arizona Master Gardener Manual, produced by the Cooperative Extension, College of Agriculture, The University of Arizona, 1998. Edited and reformatted by Texas Cooperative Extension, Harris County, September 2007 he term bulb is loosely used to include corms, tubers, tuberous roots, and rhizomes, as well as true bulbs. This publication will T refer to all of the above as bulbs. leaves A true bulb is a complete or nearly complete miniature of a plant stem encased in fleshy modified leaves called scales which contain reserves of food. Corms are the base of a stem that becomes swollen and solid with nutrients. It has no fleshy scales. The lateral bud tuber, which is an underground stem that stores food, differs from the true bulb internode Bulb or corm in that it has no covering of dry node leaves and no basal plant from which the old corm roots grow. Usually short, fat and rounded, it has a knobby surface with growth buds, or eyes, from which the shoots of the new plant emerge. Tuberous roots are the only ones Corm from this group that are real roots; their food supply is kept in root tissue, not in stem or leaf tissue as in other bulbs. Rhizomes, which are sometimes called rootstocks, are thickened stems that grow horizontally, weaving their way Tuber along or below the surface of the soil and at intervals sending stems above ground.

  • Seed, Tuber, Bulb
    Garden Education from the Salmon Center Seed, Tuber, and Bulb Exploration Activity Ages 9+ (can be adapted for younger age group if focus is primarily on observation) Overview: Most students know that plants grow from seeds, but did they know that they also grow from bulbs and tubers? The purpose of this activity is to investigate the differences and similarities between seeds, bulbs, and tubers through the use of observational skills. Students will also learn about the anatomy and function of seeds, bulbs, and tubers. Essential Questions: What do seeds, tubers, and bulbs have in common? What are their differences? Why does a seed, tuber, or bulb grow when planted, but if a leaf or stem is planted, it decomposes? Definitions: Tuber: A swollen, fleshy, usually underground part of a plant that provides food and bears buds from which a new plant arises (Examples include potatoes, artichokes, Jicama, and yams) Bulb: A short underground stem surrounded by fleshy leaves, which contain stored food for the embryo inside (Examples include garlic, tulips, daffodils, and lilies) Bud: Compact growth on a tuber and inside a bulb that develops into a leaf, flower, or shoot Seed: An embryonic plant enclosed in a protective outer layer Seed coat: The outer layer that protects the seed/embryo Embryo: The baby plant inside a seed. It has only two tiny leaves and the beginnings of a root Cotyledon: The part of the plant that provides food for the embryo Materials: ● Seeds of different shapes and sizes (If using beans, consider soaking beforehand to allow for easier dissection) ● A tuber (a potato is an easy one!) ● A bulb (try garlic or a flower bulb) ● Magnifying glass ● Dissection tools (tweezers, knife, fork, etc.) ● Seed, Tuber, and Bulb Anatomy Guide (included) Start the Activity: 1.

For the most part they are the earliest plants to bloom and most of them have exceptionally showy flowers. The gardening season begins with the snow drops and winter aconite, usually in early March. These are soon followed by Crocus, Scilla, and Chionodoxa; then come the hyacinths, daffodils, and tulips. Bulbs are also a most versatile group of plants — there is a type for any location. Attractive mass plantings may be made in solid beds, to be followed in June by annuals. Groupings may be spotted about in a perennial border or rock garden. Bulbs are attractive along paths and walks, or planted around pools, or placed in front of foundation plantings around the home. Most spring bulbs, with the exception of tulips and hyacinths, may also be effectively naturalized. Site. Most bulbs do well the first year regardless of where they are planted. Very few do well for several years unless they have a fair amount of light and generally favorable growing conditions. Planting bulbs beneath large trees is seldom satisfactory because of the dense shade cast by the trees and the competition with tree roots. Scilla sibirica, crocus, winter aconite, and snowdrops (Galanthus) will, however, give satisfactory performance under trees. Very few of the hardy, spring flowering bulbs tolerate wet, soggy soil conditions during the winter.

  • Green Ribbons and Bows by Toni Corelli
    GREEN RIBBONS AND BOWS BY TONI CORELLI The long, narrow green ribbon-like leaves lying on the ground are the first leaves of the white globe lily, also known as fairy lantern (Calochortus albus). The large green bow-like leaves are the resting leaves of the checker lily; also known as Mission bells (Fritillaria affinis). The underground bulbs of these plants produce these leaves. The purpose of these leaves is different for these two plants. Their function is to provide carbohydrates to the bulb to produce the stem leaves and flowers, but sometimes not in the same year. For the white globe lily the bulb produces a ribbon-like leaf. It is often referred to as strap shaped and can be over a foot long. It is a solitary basal leaf and lies along the ground before the bulb sends up the flowering stem. The upper stem leaves associated with the flowers are upright and the flowering stem Illustration by Linda Bea Miller show branched white globe-like flowers. Usually the white globe lily stems, leaves, and flowers will be produced in the same season as the ribbon-like leaf. The white globe lily ribbon-like leaves are prolific this year and can be seen all along the trails in the woodland and chaparral; usually it flowers in late March-April. For the checker lily, the bow-like leaves serve to add nutrients to the bulb to provide the strength needed to produce the flowering stem and leaves for another year. This broad bow- like leaf has been referred to as a resting or a nurse-leaf since usually the bulb will not produce the flowering stem and leaves in the same season.

  • Spring Flowering Bulbs for New Spring
    SPRING FLOWERING BULBS FOR NEW YORK CITY COMMUNITY GARDENS By Fred Rosenstiel DESCRIPTION AND VARIETY OF BULBS In the Fall, Spring flowering bulbs are worth planting because the reward will be a splash of color before almost anything else happens in the garden. There is such a wide choice of spring flowering bulbs that if some of every common representative group are planted there will be flowers for five months in succession – from February to June. WHERE TO PLANT BULBS Because such conditions as temperature, moisture and light influence the time of flowering, it is impossible to give exact dates for each species, but the following is a relative timetable of successive blooming periods for the more popular bulbs. TIMETABLE* Galanthus (Snowdrop) Eranthis (Winter Aconite) Crocus Scilla sibirica (Siberian Squill) Iris reticulata Chionodoxa (Glory-of-the-Snow) Anemone blanda Species Tulips (Kaufmanniana, Fosteriana, etc.) Muscari (Grape-Hyacinth) Trumpet Daffodils Single and Double Early Tulips Hyacinths Large – and Medium – cupped Daffodils Triumph Tulips Darwin Hybrid Tulips Daffodils: Short-cupped, Poet’s Double Late Tulips (peony-flowered) Lily-flowered Tulips Darwin Tulips Cottage Tulips Parrot Tulips Breeder Tulips Scilla campanulata (Wood-Hyacinth or Spanis Squill) Dutch and Spanish bulb Irises Ornamental Onions *from The Complete Book of Garden Bulbs by Marc Reynolds and William Meachem, (1967), Funk & Wagnalls, N.Y. SELECTING THE LOCATION FOR YOUR BULB BED Sunlight – During their growing season, bulbs need a reasonable amount of sunlight. Therefore, do not plant where a building will cast shade, bearing in mind that in March the building will cast the same amount of shade as it does in September.
