Good for you! They are terribly precocious; I got one about a year old and it started flowering that same summer. Is yours in a pot or the ground? It looks very green.

Hi all,

I recently obtained a few citrus trees (an unidentified Lemon? as an air layer in January, a Meyer Lemon on Carrizo a couple weeks ago, a Persian Lime airlayer in early August and a White Grapefruit on Volkamer Lemon, as well as one or two seedlings). All my citrus trees are in containers as our soil sits on a large layer of hard oolithic limestone bedrock. Since the city water is pumped from aquifers in this bedrock it is also considerably alkaline  (tested 8.3+ on my dad's pH kit).

Has anyone any experience with acidification for their water for container plants? I realize growing ground is a bit different from growing in containers. I have some battery acid on hand, but do my have a pH tester that goes under 7 to see how much I need to lower the pH to around 6 (and 5 for my blueberry). One teaspoon of 3.3% concentration battery acid drops it to just above 7, but I'm not sure that 1 teaspoon always causes 1 unit drop in pH. Any advice appreciated!

Also, I read that Volkamer Lemon is more tolerant of alkaline conditions that Carrizo. If so perhaps I could try growing it in ground if I can figure out the irrigation situation? My soil is very sandy and low organic matter, basically a mirror of south Florida. I would probably have to mulch for moisture conservation. Thanks in advance! I have questions about fertilizing as well but those can wait.

Seagrapes are di? In terms of male and female plant or male and female flowers on each plant? I ask because I don't think I've ever seen one here that didn't have fruits on it and was a mature plant. I'm not sure how long they take to fruit from seed but I have heard of people making nice wine with it (grapefruit wine is great too). We have an absolutely immense tree in our yard, easily the biggest one I've ever seem in my life.
