Lovely smelling flowers. More leafy than his neighbours (lemonade and orange).Being  well mulched and well watered makes a big difference. Growing well

Growing in a large pot and doing great.  I let the fruit ripen this year to see what we are up for.  Allowed 4 to stay on, very heavy fruit, I'm surprised the branches supported them.

Still only young and establishing.  No problems to this point - one fruit last year.  Healthy little tree.Only 3 fruit this year - hopefully more next year.

Label doesn't say what type of red grapefruit it is. It's struggling a bit - had to severely prune to get the framework right.For feeding n spraying see lemon - meyer.Aug 2010: it's doing well now and flowering. May let it keep one or two fruit at most...

An excellent piece of fruit with trees yielding up to 400kg of fruit per season when fully grown. Highly recommended!!
