The best time to plant oil palm trees is at the start of the rainy season, once the soil is moist and rains are steady. In southeastern Nigeria, that usually means April to June, and planting then gives roots several wet months to settle before the dry season.
My father always planted his palm seedlings in the rainy season, when the soil was moist.
His reason was simple and correct, because roots planted into dry ground dry out and die.
He bought young agric seedlings in plastic bags and planted them once rains had soaked the soil.
That timing still decides if new palms thrive or struggle across West Africa.
Here is the best time to plant oil palm trees, month by month, and how to judge the real rains.
It covers seedling age, false onsets, dry season planting and the steps that protect new palms, and also, planting time only, from season to planting day.

Why Timing Matters When Planting Oil Palm
A newly planted palm has lost part of its root system in the move from nursery bag to field.
It needs moist soil to grow new roots before it faces dry weather. Planting into dry soil stresses the seedling, slows growth and can kill it outright.
Planting at the right time saves water, labor and the cost of replacing dead seedlings. It also brings the first harvest closer, because a well-settled palm grows faster in its first year.
Good timing is one part of a wider growing plan, set out in the complete oil palm farming guide.
The Best Time to Plant, According to Research
The FAO’s farmer manual on the oil palm advises planting at the beginning of the rainy season. That timing lets the roots establish themselves before the dry season arrives.
The manual also advises lifting and planting seedlings on the same day. A large, intact root ball gives the palm the best start in its new hole.
Water stress later in a palm’s life is just as costly to the grower. A 2017 review in the European Journal of Agronomy found water-limited yields can fall below a third of potential where yearly water deficits exceed 400 mm.
Rainy Seasons in Southern Nigeria
Southern Nigeria has one long rainy season and a clear dry season. A 2014 study in OCL at a plantation near Benin City recorded a dry season from November to April.
That site’s wet season ran from May to October, with the driest months in December and January. Southeastern states such as Abia follow a similar pattern, with local differences each year.
Abia’s own 2026 outlook gives a clearer picture for my home state. Abia’s Ministry of Agriculture reported in March 2026 that rains were expected to start between late March and early April.
The same outlook said the season would end between late October and early November, lasting about seven to eight months. It put peak rainfall between June and September, with flood risk on low land.
| Period in southeastern Nigeria | Weather | Planting advice |
|---|---|---|
| December to February | Dry harmattan, very little rain | Do not plant, keep seedlings in the nursery |
| March | Early showers, sometimes a false start | Prepare land and holes, but wait |
| April to June | Rains settle and soil stays moist | Best window for planting |
| July to September | Peak rains, flood risk on low ground | Plant on well-drained land only |
| October | Rains begin to ease | Late planting, with mulch and watering |
| November | Dry season begins | Too late for most planting |
Beware of False Onsets
Early rains do not always mean the season has truly started for planting. A few heavy showers can be followed by weeks of dry weather that kill new seedlings.
NiMet’s James Ijampe-Adamu warned in February 2026 that pre-onset showers are usually followed by a break. He advised farmers to avoid planting because of those early rains alone.
He urged farmers to follow the onset date for their local government area in NiMet’s Seasonal Climate Prediction. That forecast is released early each year, well before the main planting season.
- Wait for steady rain. Plant after several rains have soaked the soil deeply, not after one shower.
- Check the soil. Dig a hand’s depth, and plant only if the soil is moist all the way down.
- Watch the forecast. Use the NiMet onset date for your area as a guide.
- Plan for a break. Keep water on hand in case a dry spell follows planting.
How to Tell the Soil Is Ready
My father judged by the soil itself, planting when the ground was moist enough to keep roots from drying. That simple test still works well for any small or large grower today.
- Squeeze test. Moist soil holds together when squeezed in the hand, then crumbles when pressed.
- Depth test. The soil should be moist at least as deep as the planting hole.
- Rain count. Several good soaking rains over two or three weeks usually mean the season is set.
- Weed growth. Fresh green weeds across the field show that moisture has reached the topsoil.
Soil type affects how long moisture lasts after rain, since deep, loamy soils hold water longer, as covered in soils that hold water for palms.
Seedling Age and Planting Time
Timing the nursery matters as much as timing the planting, because seedlings should reach field-ready size just as the rains begin.
Research standards call for seedlings of about 10 to 12 months old at field planting. Growers who sow sprouted seed about a year before the rains will have seedlings ready on time.
The seedlings my father bought were younger and smaller, about one foot tall. Young seedlings like these need extra care through their first dry season.
| Step | When to start, for planting in April to June |
|---|---|
| Buy sprouted seed or germinate seed | About 12 months before planting |
| Pre-nursery stage | About 12 to 8 months before planting |
| Main nursery stage | About 8 months before planting until planting |
| Land clearing and preparation | About 3 to 6 months before planting |
| Pegging and holing | About 1 month before planting |
| Field planting | April to June, after steady rains begin |
Raising seedlings to field size is covered in the oil palm nursery guide. Sprouting seed before the nursery stage is set out in germinating palm seed.
Can You Plant Oil Palm in the Dry Season?
Dry season planting is risky and rarely worth the effort without a water supply. Seedlings planted in December or January face months without rain and strong harmattan winds.
If dry season planting cannot be avoided, the young palms need regular watering until the rains come. Mulch around each palm and shade from cut fronds also reduce water loss.
Watering methods and water needs for palms are covered in watering palms through the dry season.
Planting in the Peak Rains
Peak rains from July to September bring their own risks for new palms. Waterlogged holes rot roots, and heavy rain washes soil and fertilizer away.
On low or poorly drained land, plant earlier in the season or dig drains first. On well-drained land, peak rain planting works, though heavy storms can still damage seedlings.
Steps on Planting Day
- Plant early or late in the day. Cooler hours reduce stress on the seedling.
- Water the seedlings first. Wet the polybags a few hours before planting.
- Remove the bag carefully. Keep the root ball whole when slitting the bag.
- Set the palm at the right depth. Keep the top of the root ball level with the soil.
- Firm the soil. Press soil around the root ball to remove air pockets.
- Mulch the circle. Spread dry grass, fronds or empty bunches around the palm.
Feeding young palms after planting is covered in fertilizer for young and mature palms.
Planting Time and a Changing Climate
Rainfall patterns are becoming less predictable in many regions, and early rains, long breaks and heavier storms make timing harder than in the past.
Local forecasts, soil checks and written records help farmers adjust each year. The wider risks are covered in how climate change affects palm farms. The palm’s climate needs are set out in the climate palms need.
Conclusion
The best time to plant oil palm trees is at the start of steady rains, when the soil is moist deep down. In southeastern Nigeria, April to June is usually the best window, after the false starts of March.
Raise or buy seedlings a year ahead so they reach field size on time.
Avoid dry season planting unless you can water, and plant on drained land during peak rains.
Before you plant this season, check NiMet’s onset date for your area and test your soil by hand.
Frequently Asked Questions
What is the best month to plant oil palm in Nigeria?
In southeastern Nigeria, April to June is usually best, once steady rains soak the soil. Avoid planting after the first showers of March, which can be false starts.
Can oil palm be planted in the dry season?
Oil palm can be planted in the dry season only with steady watering until rains arrive. Without water, many young seedlings dry out and die during the harmattan.
How old should oil palm seedlings be before planting?
Seedlings should be about 10 to 12 months old at field planting, by research standards. Younger seedlings can survive but need extra care in their first dry season.
Why should oil palm be planted in the rainy season?
Moist soil lets new roots grow before the long dry season arrives. Planting into dry ground stresses the young seedling, slows its growth and can kill it quickly.
