Replacing water for Hycinth bulb vase
We have a hycinth bulb suspended in a glass jar filled with water on a south
facing window sill. After a week or so the water develops a green algae on the bottom of the jar and a pale greenish tinge to the water colour. Would this algae contain nutrients *useful* for the descending bulb roots, or are we better tipping away the water and replacing with fresh water every few days. Thanks. |

I would remove the glass from the sunny site and move it somewhere darker. Replace the water. |

Your hyacinth bulb needs no extra nutrients just now; the bulb itself is the food store. Provided you bought a full-size (ready to flower) bulb, there should be enough food to generate the flower and all growth needed. Only after flowering may you need to feed the bulb, but I think many people simply discard them. I have never tried this particular technique, but a friend of mine did. Her biggest problem was mould developing on the bulb. I doubt that the algal growth you are seeing is in any way harmful. I would leave it, but change the water if it offends you. Spider |
