Zantedeschia Aethiopica 'Aethiopica'
Calla Aethiopica
Storage After Arrival
Storing iris is not advised. They should be planted as soon as possible. If they have to be stored, they should be kept in a cool area with good air circulation.
Planting Medium/Planting Procedure
Any good well-draining garden soil. Water just enough to be sure the plant's root system can establish. Good ventilation helps prevent fungal disease.
Fertilization
A low-nitrogen fertilizer; 6-10-10 or 5-10-10 is best. Lightly sprinkle small amount of fertilizer around outside of plant. Fertilize twice a year, in spring about a month before bloom and then again one month after bloom. Be careful fertilizer does not come into contact directly with rhizome.
Light and Temperature Requirements
Full sun is best. At least 5 hours of sun per day. If not planted or in pots, they should not be allowed to freeze.

More DetailsStorage After Arrival
Unpack immediately upon arrival, ventilate if not immediately planted. Store at 58-65°F. Do not store with fresh fruit, vegetables or other ethylene producing products.
Valentine and Easter Forcing
Cooling
This is the most important step and can be done according to various methods:
For Valentine
1. Plant bulbs immediately upon arrival (approx. mid-September) in pots or flats. Place in cooler at 48°F. Bring into greenhouse January 5-10. OR
2. Dry precool bulbs (not planted) at 480F until mid-October in pots or flats and continue cooling at 48°F. Bring into greenhouse January 5. OR
3. Obtain "precooled" bulbs, plant in pots or flats approximately mid-October and continue cooling at 48°F. Bring into greenhouse January 5.
For Easter
After planting keep bulbs at 48°F until the roots grow out of the bottom of the container. When the roots show, drop the temperature to 41°F. Maintain this temperature until early January at which time, depending on sprout development, the temperature needs to be lowered to 34°F andheld until brought into the greenhouse. If no cooler facility is available, the bulbs can be planted outside under a 6" layer of sand and straw cover. This method is only recommended in the Northern states where outside soil temperature is cold enough to make it possible to do this.
Greenhouse Forcing
For Valentine - start in greenhouse January 10, grow at 58-65°F.
For Easter - start in greenhouse 4 weeks before Easter, grow at 58-65°F.
Planting
Plant bulbs outdoors so that soil is 4-6" above. the bulb nose (ndoor forcing, plant bulbs at soil level) Any commercial soil or soil mix can be used as long as it has good drainage and allows for undisturbed root growth. Soil pH level should be 6-7 and should have a low soluble salt level.
The following soil mixes have shown the best results:
Fafard #2, Fafard #3-B, Fafard #4, Metro 350, Metro 360, Metro 500, and Fison Sunshine #4.
Spacing
Use 40-100 bulbs per square yard - space bulbs about 3-6" apart. Exact spacing and planting depth depends on the bulb size.
Watering
Water every other day. Always make sure that watering is done directly into the container and not over the crop.
Fertilization
Fertilize in the greenhouse only - not in the cooler. Use calcium nitrate at a rate of 2 lbs per 100 gallons of water.
Height Control
Generally this is not a concern for Valentine forcing, however, for Easter a spray application of 500-2000 ppm Florel may be needed to control height or a drench with topflor when grown in the greenhouse. See Cornell Hort website for details and application rates.

Cooling
"PRECOOLED" bulbs have been cooled for six weeks prior to shipping to customer. The bulbs will need an additional 8 weeks of cooling at 35-45⁰F after planting.
Forcing Hyacinth in Water
Place the hyacinth bulb, with a vase filled with water just to the base of the bulb, in a cool dark (40-55⁰) location for about 4-8 weeks, or until root system has developed and growth from the top of the bulb is observed. When top growth is about 2" and the root growth is to the bottom of the vase, move bulb to a warmer, brighter (50-60⁰F) location. Bulbs should remain in this location until shoots turn green. Bulbs then can be moved to a warmer location (65⁰F) for full bloom. Avoid direct sunlight.
Forcing Hyacinth in Soil
To successfully grow flower bulbs for pot or cut, a minimum of 14 weeks of cooling (45 - 48°F) is needed. Upon arrival, bulbs will need to grow for three additional weeks at 55 - 58° F to initiate the root system. After root initiation, bring temperature down to 41 - 45° F and continue growing for another eight weeks, then bring into greenhouse and force at 65° F for approximately four weeks.

Cooling
Cooling is the most important step in successfully growing flower bulbs. The main rule for almost all tulips is 14-16 weeks of cool temperature at or below 48°F. This can be done according to the following methods:
For Valentine
1. Plant bulbs immediately upon arrival (approx. mid-September) in pots or flats. Place in cooler at 48°F. Bring into greenhouse January 5-10. OR
2. Dry precool bulbs (not planted) at 48°F until mid-October in pots or flats and continue cooling at 48°F. Bring into greenhouse January 5. OR
3. Obtain "precooled" bulbs, plant in pots or flats approximately mid-October and continue cooling at 48°F. Bring into greenhouse January 5.
For Easter
After planting keep bulbs at 48°F until the roots grow out of the bottom of the container. When the roots show, drop the temperature to 41°F. Maintain this temperature until early January at which time, depending on sprout development, the temperature needs to be lowered to 34°F and held until brought into the greenhouse. If no cooler facility is available, the bulbs can be planted outside under a 6" layer of sand and straw cover. This method is only recommended in the Northern states where outside soil temperature is cold enough to make it possible to do this.
Greenhouse Forcing
For Valentine - start in greenhouse January 10, grow at 58-65°F.
For Easter - start in greenhouse 4 weeks before Easter, grow at 58-65°F.
Planting Medium/Planting Procedure
Planting medium can be any commercial soil or soil mix as long as it has good drainage and allows for undisturbed root growth. pH level should be 6-7 and soil should have a low soluble salt level. The following soil mixes have shown the best results: Fafard #2, Fafard #3-B, Fafard #4, Metro 350, Metro 360, Metro 500, Fison Sunshine #4. Plant bulbs with the flat side outside of the container and the top of the bulb should be level with the container rim. Use either clay or plastic pot but make sure good drainage is available. There should be at least 2" of growing medium under the base of the bulb to allow for a good root structure. They also prefer a rather deep, loamy soil with good drainage. The leaves are broad or linear. Tulips can be used in pots, borders, perennial gardens or beds. Use a well-drained, composted site. Plant bulbs outdoors to that the soil is 6" above the bulb nose. Use 40-60 bulbs per square yard, space bulbs 5" apart (approx 4-7 per sq. ft.) Bulb size determines exact spacing and planting depth. Plant forcing bulbs at soil level.
Watering
Water every other day. Always make sure that watering is done directly into the pot and not over the crop.
Fertilizer
Fertilize in the greenhouse only, not in the cooler. Use calcium nitrate at a rate of 2 lbs. per 100 gallons of water.
Height Control for Pots. The product A'Rest (ancymidol) has worked very effectively in controlling the length of the tulips in pots. However, varieties react differently at different times of the year to the same application. It is important that the forcers guide is consulted before using this product.
