Gardeners' Notes:

Positive poeciliopsis On Mar 17, 2015, poeciliopsis from Phoenix, AZ wrote:

Central Phoenix -- We have had better luck with Meiwa kumquat as a pot plant than with other citrus, including Nagami kumquat and limequat, both of which did not survive. The small leaves and small fruit of the Meiwa make it good for a potted plant. We have had ours for 2 1/2 years and it is doing well and bears strongly. It is in a relatively harsh location, against an east-facing brick wall with a lot of morning and noontime summer sun but afternoon shade. We give it a winter cover and does fine.

We purchased one of these almost 2 years ago now. It's slightly taller than it was and produced far less this last round than the one before. We have an almost 3 year old who really enjoyed picking the fruit and in the process, tearing off parts of the plant. Amazingly, it has survived nonetheless. I'm not entirely certain it will ever be the large plant that so many seem to have. It is definitely a fighter, though!

This plant has been loaded with fruit since early September and is still producing here in December. I was worried that it would not over winter outside, but it survived the snow we just had with no visible damage.

This plant smells wonderful, I have just received it. It is outside and doing fine so far. Plan on keepin an eye on it in the hot Houston summer, however I have seen lots of them around town so I'm sure it'll be fine.

Kumquats appear to suffer more from the AZ sun than other varieties of citrus because they are slow growing. Meiwa kumquat fruits are much sweeter and tastier than the more common Nagami kumquat. Meiwa fruit is also different than Nagami in its outward appearance being spherical in shape rather than oblong. Another kumquat, named Marumi, also has round fruit but they are smaller and spicier than the Meiwa. The Marumi tree has thorns whereas the Meiwa does not. Several Marumi trees are present on campus at Arizona State University. Meiwa kumquats are extremely hard if not impossible to find in Arizona nurseries. This is partly due to the fact that Meiwas are unusually hard to graft.
