Re: Iris Talk
I talked to the lady who sold me the TB Iris bulbs and she said they would be alright in our heat. She said they could take the 120 degree heat pretty well and I shouldn't be surprised that they might one even welt underbthat heat. Some protection from the afternoon sun might be desirable but they shouldnt die. Let's see what happens I guess

Re: Iris Talk
I wonder if he's keeping them too wet? If the heat is preventing them from flowering they really should flower in fall or spring!

Re: Iris Talk
One of the factors in bud formation is the day and night temperature. It is quite possible that night temperature does not get low enough for bud formation for TB's. Here is an interesting paper on bud formation of B. Iris plants with regard to temperature http://ashs.confex.com/ashs/2010/webpro ... r3485.html

Re: Iris Talk
Yes khabbab inheardvthis before also. I think gardenias like temps lower at night compared to day to bud. However there is good variance in temps in winter and spring so I cantvunderstand why the iris won't bloom? Could it have something to do with soil pH?

Re: Iris Talk
IMO, soil PH is normally not the culprit. Most of garden soils in lahore are balanced enough. Still i plant important plants in 2 different mediums. One is slightly acidic and one is slightly alkaline and then observe which one flourishes most. For difficult plants, you must experiment.

Re: Iris Talk
Iris should always be planted on top of the dirt. One can grow them in Lahore. The reason why your Iris are not blooming is because of the heat.
