That's not bad for what appears to be sikkimensis, but you should be able to get at least twice the growth with common fruiting types. Also, you should be able to get coccinea to flower in your garden. (I have.) Of course, these are not winter hardy.

WOW!!!!
What are you feeding those guy's LOL! What kind are your Banana's? Everything just looks wonderful.. Your fan palm..What type is it? I recieved one in a trade thats looks like that ( the red on the stem and all). Mine didn't come with any info..
Keep up the good work and thanks for sharing the pic

The biggest musa is a sikkimensis. The others are "helens" (concealed) and basjoos. Right behind me is a small ensete ventricosum. The potted fan-palm is a regular Washingtonia Robusta. Not winter-hardy, but excellent as a container-plant during the summer-months. The other plants are Cordyline Australis and a young trachycarpus, also a fan palm.
This was all planted this year, so next year it should look better.

I am curious to know what your soil temperature is at this time of the year. I ask because this temperature has a greater influence on banana growth than air temperature. That is why, even here, most growth is in late summer and early fall.

In the past, used soil heating cables to hasten growth in the spring.

Soil temperature is now around 50-60 degrees F. Since this is a south faced concrete wall, it can get warm.

Growth has been much better in late July and august, but I figured it was because of small plants and roots spreading. Very slow here in Mai/June. So most likely, it's a combo of these two factors then?
