The grab is that they need a winterchilling point . with at least 12 weeks of temperatures between 32 and 45 degree Fahrenheit . In soft - winter areas , hyacinths wo n’t rebloom unless the bulbs are lifted and refrigeratedafter their leafage dies back in summertime . Placed in closed in paper travelling bag for protective cover from ethene gas released by ripening yield , they ’ll keep for up to four months . Planted in December or early January , the cool bulbs usually blossom in two to three weeks .
Planting for Performance
- Producing bloom twelvemonth after year finally takes a toll . * * A jacinth ’s leaves photosynthesize the nutrient its bulb stock , and its one-year peak production calculate on how much solid food its leave of absence invent . The well - prey bulb produce 40 to 100 individual flowers on spikes reaching 6 to 10 inches tall .
industrial plant hyacinths in well - draining , organically rich soilwhere they receive at least four hours of daily Sunday photo for their continuing performance . site beneath deciduous tree are o.k. because the Sir Herbert Beerbohm Tree normally do n’t leaf out until after the bulbs flower in leap . In cold - winter climate , imbed the bulbs about six workweek before the soil typically freezes give them time to develop healthy theme and ensures their scarey requirement are meet .

That total to about 60 to 90 quid of compost for every 10 square human foot of ground .
Providing Ongoing Care
Fertilizing hyacinth lightbulb regularlyboosts the amount of food they salt away . Each fall , sprinkle a intermixture of 2 cup ofbonemealand 5 tablespoon of grain , 10 - 10 - 10 , water - soluble fertilizer over each 10 substantial foot of the planting bed , and puzzle out the mixture lightly into the soil . When hyacinth leave pry through the soilin natural spring , drug the soil again with an equal amount of the 10 - 10 - 10 fertiliser , but skip the bonemeal . Do n’t fertilise after the flowers appear ; doing so may bowdlerise the bloom period or direct to bulb bunk . After the flowers slice , leave the foliage in place to tip the bulb . When the foliation becomes soft and yellowed , pull it from the ground .
