Question About Pollination After Rain

alameda/zone 8June 9, 2014

This morning, I dabbed pollen about 9-10am. About 11:30, a big storm came up and we got 2" of rain. The storm came up suddenly, before it did, I dabbed pollen on a few more.

My question is, what are the chances of seeds making after this rain? How long does the pollen have to be dabbed before it "takes"? Even if they don't set seed, it was great to have the wonderful rain!

Another question, which is the best time of day to pollinate? I always thought it best in the morning. If a lily was pollinated in the late afternoon, will seeds still set?

My understanding is that the temperature is the biggest thing that will stop pollination (at least in Texas), so I always try to do it early.

I would think that anything you did before it rained would have a good chance. It should be pretty quick for the pollen to start travelling down the pistil if it is going to do so, and once it's in there, I don't think the rain will stop it.

Guess I will find out........the afternoon storm gave 2". We had another big one about midnight that gave another 2". I pollinated a couple just before the first rain came down so there probably wasn't 30 minutes from time I pollinated until the rain came. Pollen would have to travel pretty fast to have done its job. I try to do my dabbing in early morning, even before I feed my horses. This morning, it was nice and cool, some pollen hadn't even opened up yet.

We have three days rain predicted here so I am going to try----some say water and/or heat kills pollen in a short time ( old article in daylily journal) but I have one bud left on an early seedling--it's now or never!---------------Weedy
