How I'm Planting 50 Fig Trees

Updated: Jan 29, 2023

1. Introduction

Let this act as a guide for planting fig trees in a way that maximizes heat and allows you to plant your fig trees at a closer spacing.

Before I begin... I want to mention that I don't recommend the following method of planting fig trees to everyone. For whatever reason, I seem to be a bit warmer here than most of the northeast and what is working here may not work for you (this should be assumed at all times).

This is also a work in progress as I continue to learn, but this is what I believe to be one of the best ways to plant a fig in my location with little to no winter protection and with some aesthetics in mind.

2. Background Information

I also want to mention that my trees are dying just about every year to the ground or close to it. I'm in a suburb northeast of Philly and in a straight shot I am ~5 miles from the Delaware River. We frequently reach 0-5F. This year was 2F. Last year 1F.

This Hardy Chicago unk that I'm growing is the only one thus far to survive relatively unscathed two years in a row. Usually, around Thanksgiving an early low comes in and damages trees that are not fully dormant and especially trees with poor lignification, so not only are we getting damaged in the winter, but also frequently in the fall.

3. Planting Height Experiment Results

Two Key Points:

An interesting experiment that I've been doing is planting figs at various heights. 4 inches of the root ball above grade, 6 inches, 8 inches, and lastly the entire rootball encased in a 1-foot high raised bed with wooden sides.

This year and last year I discovered that I can plant figs much higher than conventional wisdom would have us believe. The reason being is that if you mulch the soil heavily, it will insulate much better and SO FAR the soil has not dropped in temperature enough even on the coldest nights to kill a single tree (even the tree in the 1-foot high raised bed planted last spring).

I don't know how long that will continue, but 3 or more inches of straw or a thick layer of stones covering the root ball on every tree seems to be key.

Additionally, I've been taking some soil temperature readings throughout the property. There's quite a big difference between bare soil, mulched soil (with either wood chips, straw, or rice hulls) & soil covered in a layer of stones.

The stones are warming the soil by at least 5 degrees more than bare soil and mulched soil is significantly cooler than both. I imagine putting down black plastic would make things even warmer than a layer of stones. My southern exposure has the warmest soil temperatures followed by southwest and then western exposures.

It makes more sense to me to treat my in-ground unprotected figs in a different way. Because if they're gonna die back all the way to the ground every year, I should at least focus on finding a way to get an earlier main crop.

Of course, through thinning, and pinching, but most importantly my point is that we should be giving our trees as much heat as possible early in the season. The same way we treat our container figs.

4. My Planting Method

Planting them higher above grade, using rocks, black plastic, and thermal mass is going to net us more in the season and that's what you see below is what I've done with the first few trees. The mounds are ~1 foot high and are now covered in brick and stones.
