Do I Really Love Fabric Grow Bags?

Rethinking my use of fabric grow bags. The Florida climate dries out the plants too fast. Certain shallow root vegetables, grown during winter, might be the answer.

After growing some things over winter and using fabric bags, I am not sure I really love these bags anymore.

I strive to have good dirt for all my seedlings. I mix bags of soil with compost and perlite or vermiculite, and add organic fertilizer, or I use Happy Frog (paid link).

But the fabric bags are dark in color. The Florida sun is blazing hot, even in February. The dark color makes the bags hot, so they dry out quickly. Also, there is little in the way of rain here in winter. The roots are not uniformly watered when the dry areas remain dry. All roots around the edge of the bag will dry out and burn from the sun.

Grow Bags For Northern Summers

I’ve purchased lots of various types and sizes of fabric grow bags in my gardening years. Up north, in New England, I had the really big circumference bags (paid link) along with smaller ones. I never noticed them drying out fast. I think these bags work well for that type of climate.

For anyone who can’t dig a garden, or has very little time for garden maintenance, the bags are perfect.

Here are some old photos of my backyard in New Hampshire. I easily grew lots in my grow bags. Growing in Florida is a completely different experience.

Florida Gardening With Grow Bags

In Florida, I tried gardening again using fabric bags and didn’t have much luck. At the time, I was still trying to grow northern crops here in the south. You can’t do that. So I failed.

I used a combination of fabric bags and a wooden raised bed. This raised bed eventually rotted away, and now it is a lump of dirt in the side yard. Lately I am adding Vegega metal raised beds to the yard and have three set up.

The wood raised bed fell apart after a couple of years.

Problems With Using Fabric Bags in Florida

The Florida climate, even in winter, can cause fabric bags to stay too dry. Fabric bags are great for getting air to the roots, but the heat can also get to the roots. The dark colors of the bags work great in the north where soil needs warming. In Florida we really don’t need that.

Last year I had some pretty awesome pepper plants growing in fabric bags. They looked great, and then suddenly began to wilt. I was being careful to not overwater, but that was not the problem. I think the peppers were not getting enough water. I didn’t know. I lost them all.

I had no idea that the peppers were so thirsty. If I had dug my fingers down into the dirt, I might have realized the problem.

As I go through the filled bags that are currently in my yard – pulling carrots and onions – I am seeing lots of very dry dirt. It seems like I am watering plenty, with water running out the sides and bottom. But in reality, the dirt is very dry.

The Bags are Not a Complete Loss

I will still use my fabric bags, but only for certain vegetables, and only in winter. This is my plan.

  • Use fabric bags for winter vegetables only.
  • Grow shallow root vegetables, where roots don’t spread to the edge of the bags. Crops like onions, shallots, 1/2 long carrots, Tatsoi, and arugula come to mind.
  • Create a section of the yard and place all fabric bags close together. This can minimize sun exposure to the sides, and keep the bags from drying out as easily. I’ve already done that for the remaining potted bags.
  • Water crops using a soaker type system such as the Haws watering can (paid link) with the brass rose. I have this type of watering can and it is excellent for watering seedlings, or soaking a particular plant. Some other type of soaker system would also work.

Advice on Fabric Bag Size

I have 7 and 10 gallon fabric bag sizes. I prefer the 7 gallon (Amazon paid link). It’s faster to fill, and large enough for what I want to grow. Now that I have decided to grow shallow root crops only, shorter bags might have worked better for my needs. But I have plastic box beds for that.

If you are gardening in Florida, choose your bag size wisely. Add good soil, and maybe mix it with coco coir, or something to minimize dry out. Plan to water any plants in the bags DAILY when there is no rain. I don’t think it is possible to overwater crops growing in these bags.

Fall Gardening is Underway

Here I have a photo of my Fall garden. It is hard to tell what is growing, and honestly not much in the way of food just yet. The seeds have all been planted except for Kale and dill. I will also grow more green beans along the way when I find space. (I’m already…

End of Summer Garden Clean Up

It is the beginning of September and my end of summer garden clean up is underway. I happily pulled up all the Seminole pumpkin vines. I managed to haul in my huge harvest (not) of three little pumpkins. Two of them have holes from something trying to bore in. I’m so over the vines that…

Fabric Bag Gardening in a Small Backyard

Small backyard space

Having a small backyard means facing some challenges when planning a garden. Throw in tall trees bordering the property taking away sunny patches, and it adds to headache. That is why I tried my hand at fabric bag / pot gardening.
My backyard is small and narrow. The picture I’ve added is one I took before I closed on my house. The slider was taped off so one would try to go out where there were no steps. Who would? Anyway… those are the old, wooden steps sitting out back at the edge of my small backyard. Although I have an acre of land, the usable part of my backyard stops right there. So the space I can use now (with a small deck that I added) is long and narrow with spotty areas of good sun.
Last summer I had planned to dig up a couple of new areas back there that tend to get pretty good sunshine, but that is so much work. I really didn’t want to have to dig and then add amendments and all that. Plus I didn’t have the time. I needed an alternative to the traditional way of gardening. So I decided to try container gardening.  But instead of regular pots I used fabric bags, in various sizes, filled with good dirt.

This large fabric bag held tomatoes, basil, radishes and some herbs. There was no digging involved, but I did buy a truckload of good loam and had to wheelbarrow it over to fill the bag. I planted my small seedlings and they took off.
I also used smaller fabric bags to plant potatoes, green beans, and carrots. I learned a few things from using these bags, and some things I will do differently this season, but all in all I was happy with them.
I wondered if I could save the bags and re-use them, so we’ll see how well they hold up when I try that this spring.
