Add This Secret Ingredient To A Container To Grow Large Cucumbers
To grow cucumbers in a limited space, grow bags are a quick and easy solution, but it’s essential to fill them with a substrate that will bring out the best in your vegetables.
According to TikToker @perkyplantparent, the secret to cultivating large grow bag cucumber vines is to fill them with a nutrient-rich bed of PittMoss potting mix instead of soil.
@perkyplantparent compared her Japanese cucumbers in grow bags filled with PittMoss to those grown in soil, and the PittMoss vines thrived while the soil vines appeared stunted.
PitMoss' official website states that its standard potting mix is made from recycled paper fiber that saves water, delivers nutrients to plants’ roots better, and is peat-free.
Soilless mixes have wetting agents that balance water retention and release, creating a light substrate that’s easier for seedlings to grow roots in than compact soil or compost.
You can buy 10-quart bags of Plentiful Organic Potting Mix for $17.99 each on the PittMoss website, or get 16-quart bags of Premier Horticulture PRO-MIX for $21.60 from Walmart.
To make your own potting soil, mix a bushel of perlite with peat moss or coconut coir, add 1 ¾ cups of lime, a ½ cup of phosphate, 1 cup of fertilizer, and a little compost.
