Yes, in fact there is!

Look up your local 'Fafard' mix distributor and you can buy one of their heavier mixes.
There's the 'Fafard' 52, 51 and 3 mixes. There is more pine bark than peat in them...With the Nursery mix, you may have to add perlite, but it holds the most pine bark.

Thanks for the recommendation. Doesn't look like Farard mix is available anywhere around me. Any other recommendations?

One local garden center recommended Coast of Maine "Bar Harbor Blend". Organic with a few things mixed in. Think this will be ideal if I mix in a little extra perlite?

Any input on this mix appreciated.

Well, it says will require less watering which worries me. It may be a great mix for annuals?

Don't you have access to pine bark?

You could make your own.....How about a Lowe's...Do you have one near by?
You do have plenty of options. It just depends on how much work you want to put in this. If you understand the concepts of mixes in containers, it will drive you to look for the best, make your own, or make do with what you are stuck with.

I am not particularly fond of most bagged mixes with too many fine particles since they collaspe fast, draw bugs, hold to much moisture too long, suffocate roots with in a short time, deprive roots of much needed oxygen, accumulate salts, limit your frequent waterings, and the structure of it may start out fine, but fall apart with a short time.

Of course the roots of a plant is the heart of it. So making your roots as happy as can be is a good start, especially with citrus.

Let me know what you come up with, please. If you are limited to a bagged mix, you could always amend it to meet your trees requirements to remain healthy and strong.

Here is what helped me understand how mixes work in containers. I hope this helps you decide what to do, use, look for.
