Growing Food Fast Enough to Keep Children Interested

The attention span problem

An eight year old will check a seedling daily for about two weeks, weekly for another two, and then stop. If your only crop takes four months you have lost them long before harvest.

Run fast and slow together.

Under a week

Mung bean sprouts in a jar. Rinse twice a day, edible in four days. Nothing else in growing is this fast and it is the best possible first success.

Cress or any microgreen on damp cloth. Five to seven days.

Two to four weeks

Radish. Kangkung, cut and it regrows. Salad leaves. Spring onion from a supermarket bunch stuck in soil.

Six to ten weeks

Bush beans. Pak choi. Chilli to first fruit if you start from a seedling rather than seed.

Months, and worth it anyway

Rice, three to four months. Sweet potato, four months, and the harvest is a genuine event because nobody can see it coming. Banana, papaya, a year or more.

The structure that works

One fast thing always in progress, one medium thing, one long thing running quietly in the background. When interest in the slow crop fades, the fast one is at the interesting stage.

Harvest and eat it the same day

Whatever it is. Growing something and not eating it is an anticlimax, and a handful of leaves eaten by twenty five children is enough. It is about completing the arc, not about the quantity.
