Transcript of Amaryllidaceae

Plant ID Crop Production Common Crops Amaryllidaceae Spacing
4-6in apart, 12-18in between rows
large onions: 16-24in between rows

Where in USA are these crops produced?
most regions of U.S. due to adaptability
very common in OR, WA, and CA

Any locally?
easily grown in home gardens
Marion, Washington, and Yamhill counties

Is Willamette valley a good place for onions?
Yes, mild winter temperatures and muck soils allow onions (and relatives) to be grown year round The Amaryllis Family Crop Nutrient Requirements Organic Methods Planting disease resistant cultivars and employing crop rotations can help to keep diseases and pests at bay

Blending a compost into your soil is usually sufficient when it comes to the nutrient needs of alliums

Mulching will help to boost the soils water holding capacity and regulate temperatures to prevent your crop from bolting, as well as, hampering competition from weeds

Planting Marjoram and oregano next to your onions can help deter root maggots

Common biological controls using beneficial organisms include: pink lady beetles, lady bugs, lacewing larvae, and predatory mites Megan Baglien

Amaryllis Weed Control History of Plant Family Folklore & Ethnobotanical Uses also... * 50 genera and 800 species

* Bulbs, Rhizomes, or corms and basal leaves

* Tropical to warm temperate perennials

* South Africa and South America Soil Structure
Grow well in basic to slightly acidic soil
pH 6.0-8.0
Loam, sand and organic matter in equal parts
Loam= sand, silt and clay
Mulches help conserve moisture and control weeds
Management Methods
Gravel in bottom of pot for maximum drainage
~ 1/2 inch
6 inches tall- add low nitrogen containing fertilizers
Brighter and taller flowers

Need plenty of bright light
Sun allows leaves to send nutrients down to bulb
Water when top of soil is dry
Compost will have some nutrients
Feed 2x/mo fertilizer for flowering plants
High amounts of Phosphorous 5-10-5

-Perianth of 6 parts (tepals not petals)
-Stamens 6
-Ovary inferior and epigynous
with 3 fused carples Ovary position
sets this family
apart from the Lily family.
In Amaryllidaceae the
inferior ovary
is considered an
advancement Perennials form bulbs or rhizomes, leaves are basal Agavaceae
Themidaceae??? Agave tequiliana FRUIT! FLESHY OR NON-FLESHY
Dehiscent or Indehiscent
Berry or Capsule Group Members: Sarah Blood mallow
pigweed crop rotation
off-season tillage
cover crops
flame weeding
heavy mulching with straw or other organic materials
soil solarization Amanda Brooks Onion root maggot Eggs are laid on plant, and maggots will burrow into and eat the bulb.
Life cycle is less than one month, three generations per year.
Can become a problem even after harvesting or storage
Best way to avoid them: remove all crop material from the field and surrounding areas.
A row cover crop, or a top layer of sand or ash directly after planting
Fly traps can be placed to catch the adults
Planting radishes alongside onions to act as a catch crop. ...Feed on a variety of crops, are a common problem in onions and garlic.
Lay eggs on underside of leaves
Adults and nymphs both feed on surface of the leaves
Scarring can kill the leaves,
makes plants vulnerable to disease,
even in mild cases, harm marketability of crops.
Eaten by lacewings, and other predaceous insects.
Plant away from grain fields, which provide thrip habitat in spring.
Remove and burn infected leaves and bulbs early in the growing season can effectively limit damage. Onion Thrips Botrytis Neck and Bulb Rot Fungal rot
Tissues turn soft, dark; look “watersoaked”
Symptoms can appear in the field or in storage; greatest risk in cool, wet weather
Crops should be well cured with little late-season irrigation, and stored in dry conditions
Damaged plants are more likely to be infected Onion White Rot Bad news: can’t be eradicated
Fungal infection
Can live in the soil for up to 15 years
Yellow and dying foliage, white mold over roots
Remove and burn infected plants Garlic varieties are Rocamboles, Porcelain, and Purple Stripe Organic Varieties of onions: Calibri F1, Rosa Di Milano, Siskiyous Sweet Walla Walla, Red Wing F1, Cortland and Red Baron.

Onions, shallots, and garlic can be stored for months

Most common flower is Narcissus, also includes lilies like spider, fairy, and royal lily Leek varieties are Tadorna, Runner F1, Bandit, Megaton F1, King Richard, and Varna Shallot varieties include Pikant, Saffron F1, Conservor F1, Camelot, and Longor
