Garden Coach on Planting Edible Starts Properly
One problem I see over and over with many clients is misunderstanding how to properly move edible plants from cellpacks into the garden. Many of my clients are just learning about gardening so starting everything from seed is a bit more than they’re ready to handle. Instead, they selectively purchase cellpack, organic vegetable starts to put into their seasonal edible gardens. And, one of the hardest lessons for them to remember is that each cellpack contains multiple starts that must be divided before they go in the ground.
It may seem strange to write this article as we go into fall, but I find this is actually a good time to learn from our mistakes and start remedying them with our fall edible crops. As I help clients clear out their spent corn and squash plants, I point out the stunted growth and poor rooting and stress infections that some of their plants have. And, usually I’m able to point to the stronger plants that I had installed to illustrate how to properly divide the starts and put them in the ground.
Because they were in a rush or because they forgot their lesson before they got a chance to finish planting, many of their starts are still multiple plants crowded together at the base with roots tangled in a 2″ mass that never grew out of its original cellpack shape (or didn’t make it far beyond those 2″). On the other hand, the plants that I had split apart and planted nearby are generally doing much better. (In the case of some corn I saw today my example plants were looking better but the pollenation had been weak all around.)
When seeds are popped into cellpack starter containers generally a few seeds go into the tiny amount of soil. This ensures that of 2-4 seeds at least one should sprout and the vendor will be able to sell an abundant pack of starts. What many new gardeners don’t realize is that each of those starts should be carefully seperated from its mates and planted on its own. Breaking roots is fine and actually encourages stronger plant growth — so long as the roots aren’t completely detatched from the rest of the plant.
If the starts aren’t seperated then the plants compete for resources and all of the starts generally becomes stressed and stunted. Production is weakened and pests and pathogens have a field day in the garden.
If you’ve made this mistake with your fall crops like kale, chard, cabbage, broccoli, lettuce or peas, rush right out there and pop them out of the soil. Divide and replant them. (This assumes you live somewhere that has a relatively mild climate. If you’re snowed in already and aren’t growing in a greenhouse, forget it.)
And, next spring, when you evaluate starts to go in the garden. Remember, one 6-pack may contain 3-4 times the 6 cells you see. And, yes, if you plant from seed into starter packs, you may find yourself dividing these as well. Thinning, whether plants sown directly in the garden or start packs going into the garden, is critical to a thriving edible garden.
