Just to touch on the red coloring in grapefruit... If you cut a branch off, the sap is red. I have cut some down that I planted in bad spots & trunk looked like it was bleeding.

Laaz, is that on own roots or grafted?

Both, although all the ones I have cut down were on their own roots.

I read somewhere star ruby can grow only 2 meters. Yours looks much bigger. My is also grafted, i hope it will grow taller than 2 meters. How much can it grow bigger if grafted

Grapefruit will grow quite a bit larger than 2 meters. If it is grafted on a dwarfing rootstock it will be a bit smaller, but grapefruit grow as very large trees.

that is good news, i want my tree to grow as big as possible. I think, my rootstock is citrange troyer, if i remember correctly.

Try growing some from seed, that way they will produce large trees.

i have some 15 citrus grown from seed. they are still very small.

This is my Ruby red at about a year & a half old from seed.

My pummelo seedling is like that, Laaz. Tall, lanky, and big. No flowers this year so far, bummer.

incredible, my citrus grown from seed are 20 cm tall, but they are mostly lemons.

some 8 months old

You see that palm in the back? It is now taller than my two story house.

Patty you know pummelo do not come true, right?

it,s like you live in Amazona.

Why yes I do, Laaz. All pummelos and many pummelo hybrids are monembryonic. That's why I got this Tahitian pumello seedling for $5.00 from my local nursery. I informed them that this was not a Tahitian pumello, but some unknown hybrid, and since they couldn't sell it for $50.00, I'd be happy to take it off their hands for $5.00 It is my "experiment" in my little citrus orchard.
