I live in Phoenix, AZ. I have a jacaranda that is about 8 yrs old, about 25 ft tall, only the base (suckers) have ever been trimmed. My tree has never bloomed (it did have one at the nursery when I bought it years ago). Any suggestions? Thank you
The dryer the season the more flowers and seeds produced. Don't feed and don't water too much. They do best here in drought conditions. They flower at the beginning of summer. Grafton in NSW (Aust.) is planted with avenues of Jacaranda Frm Wikpedia "native to tropical and subtropical regions of South and Central America, Mexico, and the Caribbean" http://www.burkesbackyard.com.au/19...acarandas_and_other_monsoonal_deciduous_trees http://hubpages.com/hub/jacaranda Liz
If it gets too much shade, it will not flower or will produce fewer blooms. Also Jacaranda prefers a sandy soil that drains well.
Equally, if it feels at all threatened by winter temperatures, it will delay blooming. Try a flowering tree fertilizer (high N).
i have the same problem and live in Calabasas. The tree has a direct exposure to to the south and gets full sun, but never bloomed. I wanted to blame my numbskull contractor, but it has been watered thoroughly ...maybe that is the problem...I was told that there plants of male gender that don't flower. Is that true?
No, jacarandas are monoecious (one house), meaning that every individual tree produces both pollen-producing and ovule-producing structures. So, no strictly male plants. By way of an aside, don't assume that because an individual plant of a different species is male (e.g., holly) that it doesn't flower.
Does age of the tree have anything to do with first expected bloom? I had a Jacaranda (from Bali) it never bloomed, likely because it was a potted plant for eons.... 12 years....
