In our laboratory the green pod method of sowing orchid seed is preferred to the dry seed method. The seed capsule should be harvested while the seed is viable but before the capsule splits.
Optimal harvesting time is specific, not only to genera but to individual clones, harvesting time will vary as a result of extremely complex inter-relations between generic and environmental factors.
Time intervals listed below are meant as a general guide line for those attempting crosses using the genera listed. Adjustments must be made by individual breeders to compensate for local conditions.
The following is a table of harvesting time compiled from records of our own hybridizing program. |

5 to 7 months |
After 65 days some Vanda seed capsules may turn slightly yellow but are not ready to be planted and should be allowed to remain on the plant the full length of time. If the capsule contains no viable seed it will usually continue to turn yellow and drop off. |
Vandopsis |
5 to 6 months |
Vanilla |
2 to 3 months |
Zygopetalum |
7 to 9 months |
NOTE:
The above mentioned time intervals refer to the plant carrying the seed capsules; usually the pollen parent does not influence the time interval.
Example:
- Psychopsis papilio X Oncidium luridum - requires 100 days.
- Oncidium luridum X Psychopsis. papilio - requires 7 months.
Unfortunately, the time required for complex intergeneric hybrids is only established after the capsule splits. One can safeguard against splitting by making 2 or more seed capsules of the same cross and immediately after the first one splits, the remaining capsules are harvested.
In most cases, the longer a seed capsule is allowed to remain on the plant, without danger of loosing the plant or the seed capsule, the better the results obtained.
