Bud Drop Comments
BUD DROP: Causes Other Than Ethylene Fertilizer imbalance might cause it, or trace elements deficiency; root damage has caused bud drop, as has 0
BUD DROP: If Pollution Is Not Present This is hard to explain, except the possibility the plant is self-pruning to sustain the rest of the buds. A73-906 0
BUD DROP: In Cymbidiums May be caused by several things: temperature dropping too low when buds are developing; shortage of water while forming or about to emerge; a weakened condition caused by lack of fertilizer, too much water, or insect damage. A59-414Often follows a very bright winter or spring day after a frosty night; this causes a sharp rise in the temperature which produces metabolic confusion; expulsion of buds follows in 48 hours. OR76-128; refer also to A80-739 0
BUD DROP: In Dend. Phalaenopsis It frequently happens in the fall; the plants grow in good humidity in the summer and early fall then the temperature drops, the heat comes on in the greenhouse and the root system cannot cope. A85-1118 0
BUD DROP: In Dend. Phalaenopsis Types They are highly susceptible to damage by ethylene caused by gas heaters, wood-burning stoves, open fireplaces, burning brush outside the greenhouse, and unvented propane burners. A81-810 0
BUD DROP: In Late Fall and Winter Especially noticeable in Dend. phalaenopsis types; it is caused by water stress when heating conditions change suddenly and indoor warmth causes plants to lose moisture faster than the roots can supply it and bud loss adjustment occurs. F84-216 0
BUD DROP: In Paphiopedilums Caused by sudden temperature drop especially in early winter when one sunny day there is a fast heating lip of the greenhouse and as quick a drop at night. OD86-139 0
BUD DROP: In Phalaenopsis Air polluted with ethylene is the main reason. A74-502Caused by air pollution, lack of vigor in the growth, improper temperature range, or inadequate light. A81-266Ethylene is the only cause; it can come from artificial gas heat; automobile exhaust, burning brush and wood. A79-334It may happen when plants are moved into the home after summering them outside or in a greenhouse; under lights they may get too much light or warmth, causing low humidity and stress; growing indoors in a window under natural light usually means the humidity is too low; other causes are too much drying, or too cold, or air pollution.
