Media Aloha Lily ® varieties are somewhat moisture-loving; they can, however, survive and recover from extended pe- riods of drought and will perform well given sufficient water. The bulbs will suffer from over-saturated condi- tions, so a well-draining media is critical to producing top quality plants. Planting • Plant bulbs 0.75-1-inches (1.9-2.5 cm) deep in containers or up to 4-inches (10 cm) deep in beds. • Deeper planting in regions with cold winters will add in protecting bulbs from cold injury. • Water-in the bulbs thoroughly after planting. Growth & Development The crop withstands a wide range of light conditions from 5,000 to 10,000 foot-candles (54,000-108,000 lux). Aloha Lily ® varieties are very adaptable to light intensity. High light intensities will produce very compact plants with darkened (“bronzed”) leaves and short floral racemes. In conditions with very high light levels, floral development may be slowed somewhat. Low light conditions will produce elongated leaves and floral racemes. Growth regulators may be required to produce high quality plants in low light conditions. WORK WITH YOUR BROKER TO DISCUSS THE USE OF GROWTH REGULATORS WHEN GROWING PLANTS IN LOW LIGHT CONDITIONS. Light Levels • High light levels (full sun) can result in darkened (“bronzed”) leaves and dark blooms. Higher light can be tolerated during cool & humid periods. • 30% shade often provides optimal light levels. • Low light levels can result in stretched (elongated) leaves and blooms. See notes on height control below. Temperature • Aloha Lilies are robust growers that tolerate various temperatures but truly prefer moderately cool- to-warm conditions. Optimum temperatures for plant growth and flowering are as follows: • Days @ 60-85°F (16-29°C) while preferably cooler than 75ºF (21ºC) maximum / Nights @ 40- 60°F (4.5-15.5°C), with an optimal range of 55-60°F (12.5-15.5°C) • A diurnal (night to morning) drop in temperature yields the best results. • Cool nights and clear days promote stronger and shorter stems and leaves. Forcing • An initial forcing phase can improve uniformity of emergence by using a flat 60-62°F (15.5-16.7°C) until the plants are 1-1.5 inches (2.5-3.8 cm) tall. This initial phase can be sped up by warmer temperatures, up to 70°F (21°C). The plants should be watched for stretching if higher initial temperatures are used.

Aloha Lily® Eucomis varieties are hybrids developed from South African species. They are day-neutral geo-phytes. The parental lines are native to regions that receive summer rainfall and have dry winters. Soils in those regions are typically well-draining and have high organic matter content. The Aloha Lily® varieties have been selected for adaptability to a wide range of conditions as well as for their cosmetic characteristics. Golden State Bulb Growers® continually works to determine the optimal growing practices for these varieties. Work with your broker to keep informed on the latest developments.

Receipt and Storage of Bulbs• Inspect the bulbs upon receipt. Bulbs should arrive dry and unbroken.• If bulbs are to be stored prior to planting, place them in 45°F (7.2°C). •Time to flower is affected by storage duration. CONTACT YOUR BROKER TO DISCUSS PLANS TO STORE EUCOMIS BULBS.

MediaAloha Lily® varieties are somewhat moisture-loving; they can, however, survive and recover from extended pe-riods of drought and will perform well given sufficient water. The bulbs will suffer from over-saturated condi-tions, so a well-draining media is critical to producing top quality plants.

Planting• Plant bulbs 0.75-1-inches (1.9-2.5 cm) deep in containers or up to 4-inches (10 cm) deep in beds. • Deeper planting in regions with cold winters will add in protecting bulbs from cold injury.• Water-in the bulbs thoroughly after planting.

High light intensities will produce very compact plants with darkened (“bronzed”) leaves and short floral racemes.

This initial phase can be sped up by warmer temperatures, up to 70°F (21°C). The plants should be watched for stretching if higher initial temperatures are used.

Aloha Lily® Growing Guidelines Other Temperature Considerations• High daytime temperatures, such as in hoop houses, leads to soft and stretched growth.• Any rise in temperatures during far red light period (sunrise to sunset) can severely impact plant stretch.• Aloha Lily® plants are hardy to 28-32°F (-2 to 0°C), while bulbs are hardy to 10°F (minus 12.2°C). Foliar injury can occur in temperatures below 38°F (3.3°C). A fungicidal drench to prevent infection of cold-injured roots is a good preventative practice. Humidity• Aloha Lilies benefit from moderate-to-high relative humidity. Air movement is important in enclosed condi-tions to prevent overly soft growth. HAF (horizontal air flow) systems generally work well for this purpose.Days to Flower• Days to flower (DTF)/Weeks to Finish typically ranges from 13 to 16 weeks. The time required to finish Aloha Lily® plants depends on the bulbs’ storage duration and local growing conditions. Please have your target fin-ish dates available when placing your order.

Water Management• Water freshly planted bulbs thoroughly.• Maintain soil moist until substantial sprouts emerge.• Keep constantly moist [but not soggy] until peak bloom and then decrease moderately.

Fertility• Aloha Lilies are low to moderate feeders. Too much fertility can result in leafy or “grassy” plants with slight leaf tip burn.• Use a soil incorporated 30-day release pre-plant charge of nitrogen and potassium (containing little or no phosphorous). This will produce good early establishment of roots and improved early vigor.• At approximately 3-4 weeks, begin a semi-balanced liquid feed @ 50-75 ppm w constant using 20-10-20 plus minor elements.• Frequent leaching cycles at no less than 2:1 should occur to prevent leaf tip burn from excess salt accumu-lation.• Fertigation can stop once topknots begin to develop. Additional fertilizer during raceme development may lead to leaf tip-burn.

Height ControlIt is important to appropriately time crop spacing and optimize cultural inputs to minimize PGR requirements. Numerous variables can separately or together affect growth habit. CONTACT YOUR BROKER TO DISCUSS THE NEED FOR PLANT GROWTH REGULATORS IF YOU ARE GROWING IN LOW LIGHT CONDTIONS.• Height Control During Growth • Cooler night time temperatures – below 60°F (15.5C) - can help in the production of compact plants. • Low light intensities can promote plant stretching. Current research has shown some benefits from a pre-plant dip in a solution of paclobutrozol at 45-60 ppm for one hour. Allow bulbs to dry for 24 hours prior to planting. This treatment may increase finishing time by 1-2 weeks. CONTACT YOUR BROKER TO KEEP INFORMED ON THE LATEST RESEARCH.• Post-Harvest Height Control • Aloha Lily® varieties have extended post-harvest shelf life. Plants will continue to grow on the shelf. If plants are to be marketed in low light conditions, use of a plant growth regulator drench to prevent stretching is recommended. • Apply a single Bonzi (paclobutrazol) application at 7.5-10ppm. • Timed when “almond sized” top-knots are observed in leaf rosettes.
