If someone had asked me if I used grow bags even two years back, I would have said “Why would I use grow bags when I have a nice garden!?”
Last year I discovered a reason to use grow bags and this year I’ve discovered even more reasons.
Reason #1 – Eggplant – Flea Beetles
We enjoyed eggplant last year for the first time in 34 years of gardening — all thanks to grow bags. No matter where I ever planted eggplant plants the flea beetles ate them up before they had time to get big enough to withstand the attack. It was like that at our previous place and it’s been that way here — even though I’ve tried almost every spot on our acre of ground.
Until last year, eggplant was never one of my “have-to-have” crops. Eggplant in the store is not that good and Bill and I were never that crazy about it. But last year I discovered some delicious recipes which enabled us to really enjoy our abundant harvest from the two eggplants plants in my one grow bag! Now I’m hooked on eggplant!
Three grow bags are ready in garden awaiting two plants each of 3 different varieties of eggplant. I can hardly wait!
Reason #2 – Japanese Turnips – Flea Beetles love them as much as eggplant.
I was ok with late plantings of these turnips. (Flea beetles only bothered the spring planting.) Since I’d winter sown several jugs of these delicious turnips for early planting I ordered several lower grow bags for the seedlings.
February 22nd I transplanted the seedlings into the grow bags in the garden. If the forecast calls for temperatures below 32, I’ll cover with row cover fabric to keep them a bit warmer.
Reason #3 – Chance to Double or Triple my Yield from Potatoes
I enjoy planting potatoes in the ground. Digging in the earth for new potatoes is a joy that I look forward to each year and won’t give up. Because —there is nothing — I repeat — nothing — like the taste of new potatoes fresh from the garden!
In spite of that – the chance to double or triple my yield from 4 or 5 seed potatoes by planting in a grow bag is very appealing to me.
Here’s what I’ll do:
- I’ll use the largest grow bag (25 gallons) — fill it with about 3 inches of rich garden soil and then a layer of straw — plant about 4 or 5 seed potatoes — cover with 2 inches of good garden soil rich in organic matter – another layer of straw — and when the plants grow to 4 inches – add more straw to cover all but the top inch or so of leaves. Continue this process until they are far above the top of the grow bag.
Why increased yields?
- The principle behind this increased yield seems to be that by allowing the stem to grow up and covering it with straw, it in turn increases the space for stolons to grow from which the potatoes grow.
Watering and Why
- If you’re a regular reader you know I’m not set up for watering a garden — so I don’t and never have. But with this grow bag of potatoes, if we don’t get rain every week I’ll use a watering can of reserve rain water to water them to keep them growing their best. This will help me make the most of the grow bag experiment.
- When the vines die back, I’ll let the potatoes “cure” in the ground (the bag) for an indefinite period of time. Because of the bag, the voles won’t get them while I wait. These will be the last potatoes harvested and eaten. Can hardly wait to see how many I get!
Reason #4 – To save my sweet potatoes from voles.
I planted sweet potatoes for the first time last year. They were planted outside the garden because no room was available inside the garden. The voles got almost all of them. (In case you don’t know what a vole is — it’s similar to a mouse, but lives underground.)
Since sweet potatoes are a treat — and not a “have-to-have” crop – I allotted only one large grow bag to grow sweet potatoes. The vines can sprawl down into the garden, root and produce if they will — but I’ll really be looking to what’s in the bag for my sweet potatoes.
Reason #5 – To utilize space in the garden where I can’t plant into the soil.
There’s a path between the fence that surrounds the garden and the garden beds. Placing the bags strategically along this path and using some soil from the path to fill the bags works out great. I’m able to grow more things by making use of space that is usually only used for walking.
Soil for the Bags
In case you’re wondering, I throw a handful of straw into the bag and then fill it with a mix of soil and leaves (80/20) shoveled from the path on the side of my garden. It’s been covered with leaves and straw over the years, so it’s great soil. And yes, I mulch the top.
If you decide to use grow bags, be sure to get the really good ones made from a two layer special fabric that is breathable and allows for good drainage. I told all about them in my post Eggplant and Grow Bags a Great Combination.
Grow bags are great problem solvers in the garden as well as outside the garden.
Organic gardening is easy, effective, efficient — and it’s a lot healthier.
