Green Pepper Growing Calendar: Sowing to the Last Pick

The frying pepper year stage by stage, judged by soil and night temperature rather than dates, with the jobs that are easiest to miss at each point.

The five turning points

A season with this crop hinges on five moments. Each is judged from the plant or a thermometer rather than from a calendar, which is why the same pepper behaves so differently in two gardens a few hundred miles apart, and why written dates from your own garden beat any general schedule.

Turning pointWhenHow you judge it
Sowing8 to 10 weeks before last frostCan you hold 80F (27C) at the compost
Planting out2 to 3 weeks after last frostIs the soil above 60F (16C) at 4 in (10 cm)
Removing the first pod2 to 4 weeks after plantingHas the first flower set in the fork
Starting the picking rhythmFirst pods reach hand lengthAre you back on the plant within 3 days
ClearingBefore first frostHave nights dropped below 50F (10C)

Everything here shifts by one to two weeks with the season. Peppers are slower and more heat dependent than almost anything else in the vegetable garden, so err towards later planting into warmer ground.

Raising the plants

Peppers are sown early and grow slowly, and the commonest mistake is sowing them alongside tomatoes and then planting them out alongside tomatoes too. A pepper needs a longer run in warmth before it is fit to go out, and it needs warmer ground when it gets there.

StageJobsEasy to overlook
10 weeks before last frostSow into real warmthGermination wants 80F (27C); a cool sill gives nothing
8 weeks beforeTransplant into individual potsHandle by a seed leaf, never by the stem
6 weeks beforeMaximum light, cooler by dayWeak light now gives leggy plants you cannot fix later
4 weeks beforeFirst weak feed at quarter strengthOnly once the first true leaves are properly open
2 weeks before plantingHarden off graduallyA week outdoors, longer each day, in shelter

A bought plant catches all of this up, and for two or three plants that is usually the sensible choice. Pick a short stocky one with no pods on it.

Planting out and the first month

This is the month that decides the size of the plant, and almost none of it involves feeding. The work is warmth, water, support and taking the first pod off. A plant that comes through these four weeks stocky and well rooted will crop for months; one that was rushed into cold ground will not.

Planting daySpace 18 to 24 in (45 to 60 cm), three canes, water inCanes go in now, not later through the roots
First weekWater every 2 or 3 days, no feed at allA cutworm collar saves a plant you raised for 10 weeks
Second weekCheck ties, mulch once the soil has warmedMulch over cold soil keeps it cold
Third weekRub off shoots below the first forkThey reappear weekly; keep going over it
Fourth weekTake the first flower or pod off smallThis is the highest value job of the whole month
First pods setFirst feed, half strengthFeeding earlier gives leaves rather than pods

Main crop: the picking rhythm is the whole job

Once the first pods reach hand length the season becomes a rhythm rather than a series of jobs. Pick every two or three days, feed every ten to fourteen days, water by the weather, and check the ties as the branches load up. Nothing here is complicated, and all of it depends on not missing a pick.

Fix the interval to days you can actually keep, such as every Tuesday and Saturday. A plant picked twice a week for three months produces two or three times what the same plant produces when picked whenever someone remembers.

StageJobsEasy to overlook
First pods pickableStart a fixed twice-weekly pickLook inside the bush, not just around the outside
Full productionFeed every 10 to 14 days, water daily in heatPods getting shorter means the plant is hungry
Branches loading upAdd a twine loop around the canesForks split without warning under 20 pods
Any week you missedStrip every mature pod, water, feedFlowers return in about 10 days
Aphids appearWash off, repeat every few daysThe colony is in the middle of the bush first

If you are going away for a fortnight, pick the plant completely bare before you leave, even the small pods. You will lose far less than if you come back to a plant that has shut down around a dozen tough red pods.

The midsummer pause and the autumn flush

In most warm climates there is a stretch in the middle of summer where flowers drop and almost nothing sets, because the pollen fails above about 90F (32C) by day or 75F (24C) at night. This type usually keeps trickling out a few pods through it and then comes back hard.

The job during the pause is not to force a set, which you cannot do, but to hold the plant in condition: keep it watered, feed lightly, keep aphids down, and keep picking whatever it does give you. Within about two weeks of the weather breaking you should see a heavy flush of flowers, and that autumn set is often the best crop of the year.

StageJobsEasy to overlook
Onset of heatShade cloth up, water morning and eveningPut shade up before the drop, not after
The pauseWater, half strength feed, watch for mitesDo not overfeed to force a set; it will not work
Weather breaksFull feed, expect a flush of flowersClear any pods left on so nothing suppresses it
Autumn flushBack to the twice weekly pickCooler nights mean pods fill a few days slower
Early autumnKeep feeding while nights stay above 55F (13C)Growth still looks fast but the season is short now

Clearing up, and recovering when the season slips

Once nights drop below about 55F (13C) stop feeding and keep picking; row cover thrown over the plants on cold nights buys another fortnight. Below 50F (10C) the plant effectively stops filling pods, so pick everything left whatever the size and let the last handful color indoors. Clear the plants before frost, and do not compost anything that wilted or spotted.

Most seasons go wrong somewhere. What matters is which job absorbs the delay, because some slips cost you a fortnight and some cost you the crop.

What slippedWhat happensHow to recover
Planted into cold soilThe plant stunts and stays small all seasonCover it, do not feed, and wait for warmth
Let the first pod grow full sizeThe plant stops extending for weeksPick it now; growth resumes within a fortnight
Missed two weeks of pickingFlowering stops, pods go tough and colorStrip everything, water, feed; flowers in 10 days
Never stakedA fork splits and takes a third of the cropCut the tear back cleanly and tie the rest in
Watered irregularly in heatTough creased pods, some unexpectedly hotMulch and fix the interval; the next set comes clean
Missed the shade clothFlowers drop for several weeksNothing to do now; keep it fed for the autumn flush

The one slip you cannot recover from is a late start in a short season. If you are planting more than three weeks after your usual date, top the plant, keep it in a container against a warm wall, and expect a smaller crop.
