How to Prune and Train Green Chili Peppers: Keep More Branches for Green Picking, Two Stems in a 3-Gallon Pot

Green picking lets you keep more branches

How pepper branches double at every flower, and how to decide where to cut, is covered in the shared guide "How Pepper and Chili Branches Multiply". This page is only about a green chili grown for green picking: how many branches to keep and where to stop.

A green chili is picked three to four weeks after flowering. Each pod sits on the plant for a short time, so the load per pod is a fraction of what a paprika or a red-ripening drying chili carries. That is why you can leave more branches than on those crops, and why a branch that carries a flower is, as a rule, not cut.

It is not unlimited. Branches that grow toward the center and branches that overlap a neighbor never see sun and only make small pods. Keep the plant open enough that you see patches of soil from above and daylight inside from the side, and keep every branch that fits inside that rule.

1. Keep flowering branches A branch that has made one or two leaves and set a flower at its tip is your harvest. If it points outward into the light, leave it, however many of them there are.
2. Cut only inward and overlapping branches Remove branches growing toward the center, and of two branches running the same way with leaves touching, the weaker one. Leave everything else alone through summer.
3. Never more than a quarter to a third at once When you do thin, take at most a quarter to a third of the canopy, every week or two. A hard cut exposes pods to sunscald and leaves you weeks without a harvest.

Pot size sets the stem count: two in 3 gallons, three in 4 gallons or more

Most green chilies are grown in containers, and the number of stems follows the volume of soil. A 3-gallon (10 L) pot takes two stems, the leader plus one side shoot. A pot of 4 gallons (15 L) or more, or open ground, takes three stems, the leader plus two side shoots. Three stems in a small pot run out of water and feed in midsummer and the pods shrink.

Two stems means fewer branches, so each one grows thicker and the pods come out an even length. Three stems gives more pods, but each stem needs its own stake or the fork splits under the weight of the crop in a summer wind.

Strip the shoots below the first flower and set the frame

Two to three weeks after planting the main stem sets its first flower and forks into two or three right below it. Of the side shoots emerging from the nodes below that fork, keep only what the frame needs and remove the rest. For two stems keep the one vigorous shoot right under the first flower; for three stems keep two.

1. Find the first-flower node Count up the main stem to the first flower or bud. If the stem divides there, that fork is the reference point for the whole frame.
2. Keep the vigorous shoot right below it Keep one thick side shoot immediately below the fork for a two-stem frame, two for three stems. Choose shoots that point away from the leader so the plant opens out.
3. Rub off everything lower Snap off every shoot below the ones you keep before it reaches 2 in (5 cm), with a sideways push of the thumb. Work on a dry morning and check again two weeks later.
4. One stake per stem Give each stem its own stake and tie it in a loose figure eight just above the fork. Two stems spread apart; three stems meet in a tripod.

Pick the first pod at thumb size

The first fruit sets while the plant is still small. Letting it size up stalls growth and slows every branch that follows. A green chili is picked green anyway, so there is no reason to wait: take the first pod at about 1.5 in (3 to 4 cm), thumb size, and keep the second and third tiers on the small side until the plant has filled out.

Once the plant is bushy, move to the normal rhythm of picking each pod three to four weeks after its flower opens. A single pod left too long pulls energy to itself and the next flowers drop. Picking clean is the one habit that keeps a plant with many branches from wearing out.

1. Take the first pod at 1.5 in (3 to 4 cm) As soon as the first flower has set, pick the pod at thumb size. It is too small to cook with, but it is the harvest that keeps the plant growing.
2. Pick small until the plant fills out Take the second and third tiers a size smaller than usual until the plant has 4 to 6 branches and a full canopy.
3. Leave nothing past four weeks Twice a week, look inside the plant and pick anything more than four weeks past its flower. Pods hidden behind leaves are what tire the plant.

A plant set out in late summer: add no branches, turn its flowers into pods

Leftover nursery plants and rooted cuttings sometimes go in the ground in late summer or early fall. Train one of those like a spring plant and it will add branches but frost arrives before they produce. A new branch needs 6 to 8 weeks to flower and another 3 to 4 weeks to make a pickable pod, 9 to 12 weeks in all.

A late plant keeps the branches and flowers it arrived with. Keep shoot removal to a minimum, pinch the tips that push out past each new fork, and send everything into the flowers and pods already on the plant. Where the first frost comes about twelve weeks after planting, that gives one or two pickings from the flowers it had when planted.

1. Keep every branch it came with Do not reselect a frame on a late plant. Keep every branch and flower, and remove only the side shoots below the first flower.
2. Pinch the tips past each new fork Pinch any shoot that extends after planting back to two leaves. The energy that would have made new branches goes to the flowers and pods already set.
3. Feed lightly, water steadily With no new branches to build, feed less than a spring plant but never let the pot dry out. Pods swell more slowly as nights cool, so move a pot against a sunny wall.
4. Clear the plant before frost Pick every pod, however small, before the first frost. If you want to keep the plant, switch to the steps in the harvest and overwintering guide.

Thin inward branches and lower leaves to let light in

Because you keep more branches, the inside of a green chili crowds faster. Remove inward and overlapping branches and the leaves below the first pod a little at a time, so light and air reach the center. A closed canopy shelters aphids and spider mites and hides the caterpillars that bore into pods.

A plant that is being picked green is better thinned branch by branch than cut back by half in midsummer. A hard cutback stops the harvest for two to three weeks; thinning lets you keep picking while the plant recovers.

1. Cut inward branches at the base A branch growing from a fork toward the center never gets sun, however long it grows. Remove it at the base as soon as you see it.
2. Strip the leaves below the first pod By the time the first pod sets, the leaves below the fork have done their work. Take them off as they yellow to let air through the base.
3. Thin flowerless and weak branches Cut at the base any branch with three or more leaves and no flower, and any thin branch making only small pods, so the rest get the energy.
4. Feed and check water after a cut Give one feed on the day you thin. With fewer leaves the soil dries more slowly, so watch for overwatering.
