Tropical Fruit Discussion / Building a raised bed/tree: How big?

« on: May 12, 2018, 08:59:26 AM »

Good day--

As I am two blocks from the Gulf of Mexico and storm surges 2-3 times each summer leave a few inches of brackish over my property, I have my citrus trees in raised beds constructed from landscape ties or 2" x 12" PT lumber. In the past I have made the beds 6' x 6' square, but this requires many trips to the box store for bags of compost and soil in my small Fiat.

At any rate, I have just purchased a 30gal Oro Negro avocado, and from google searches, I see many references to avocado trees and 4' x 4' raised beds. The 4' x 4' seems excessively small for sufficient root growth. On the one hand my space is limited and I would be much happier with an Oro Negro that only grows to 12' or so without having to constantly prune it, but I'm not sure if 4' x 4' is ok for an avocado tree, as my experience is that their roots are shallow & wide.

May I know your thoughts?

Tropical Fruit Discussion / Avocado Tree Advice - Help: Wurtz + Oro Negro

« on: May 07, 2018, 10:53:33 AM »

Good afternoon:

We live on a barrier island off the Gulf Coast of Florida and as we have a planting area of @10-12ft in diameter available, we would like to plant a second avocado tree to compliment the Day variety that we already have on our property. A big issue is space: There simply isn't room for a tree that will develop into a 20ft canopy or will grow to be 30ft tall. My wife and I have tried the Oro Negro which tastes great, but not the Wurtz. The Oro Negro and the Wurtz are two trees that we have access to in 25gal containers.

From what I am seeing and hearing from growers, the Oro Negro will grow to be 30ft tall...in 25 or 30 years. I suppose it can also be pruned if it gets to be too big. What attracts us to the Wurtz is that it appears to be the only true "dwarf" avocado tree that will fit nicely into the limited space we have available.

Any thoughts, opinions, or experience that anyone may be able to share?

Also, how much of an impact does having an A-flower avocado tree (such as our Day) planted in relatively close proximity to a B-flower avocado tree in terms of yield?

Thank you.

Tropical Fruit Discussion / Day Avocado...Help!

Hello--

My Day Avocado tree was planted 2 1/2 years ago, and it had been doing very well up until it first started growing avocados in the early spring/late winter. Since then, the branches have been wilting and large black splotches have appeared. After propping the main branches with Y-shaped wood crutches, the main branches have returned to their "normal" shape, but the secondary branches are limp like wet spaghetti, and some of the main branch tips are turning black. I did spray liquid copper all over the tree about 2 months ago as my local nursery advised, but I see no change.

This particular avocado tree has 3 main branches...one is doing reasonably well, but the other two show blackness from their outer tips to about 2' or so in. The leaves look good, with minor yellowing toward the top of the tree.

I am suspecting too much water as the culprit, yet none of my other fruit trees, vegetables, or shrubs are having any problems. I should also mention that in this, the first year of harvest, the tree in question has yielded approximately 50 avocados. All advice welcomed!
