The growth stages of lemon tree are
- Seedling stage
- Vegetative stage
- Flowering stages
- Fruiting stages
Guide to Lemon Tree Growth Stages: From Seedling Stage
The first stage of growth is the seed germination stage. After planting a lemon seed, it will begin to germinate.
Germination
Germination begins when the seed absorbs water, and sprouts begin to emerge. The seed will crack open as the embryonic root, called the radicle, emerges first.
Soon after, a miniature set of leaves called cotyledons pop out of the soil. This entire process of germination typically takes between 1 and 3 weeks.
Cotyledon Stage
Once the cotyledons emerge, the seed has entered the cotyledon stage of development. At this point, the seedling is entirely sustained by food reserves stored within the seed.
The cotyledons are the first “leaves.” They can photosynthesize and store energy when true leaves emerge.
First True Leaves
After 2–4 weeks, the first pair of true leaves will sprout above the cotyledons. This signals that the lemon tree seedling is shifting from relying on the nutrition in its seed.
It is beginning to photosynthesize food through its green leaves. At this stage, the root system will also begin to develop. It will branch out underground in search of water and nutrients.
Citrus Tree Growth Stage: Vegetative Stage
Once the first true leaves form, the lemon tree seedling enters the vegetative growth stage. In this stage, the focus shifts to establishing a strong root system. The plant also produces new leaves, stems, and branches above ground.
Root System of Lemon Tree
A deep, well-established root system is vital for healthy lemon tree growth cycles. During this stage, the seedling will direct most of its energy below ground. Roots will multiply and expand their reach to absorb water and nutrients from the soil.
By 4-6 months, the root ball will be large enough to support the lemon tree through its later life stages. A spreading root structure helps stabilize the plant. It also collects what it needs from a larger area underground.
Producing New Leaves
The lemon seedling has an expanding root system that absorbs key resources. This allows it to focus on producing new stems, leaves, and foliage above ground. Leaves are its food factories. Photosynthesis occurs there. So, rapid leaf production is a sign of good vegetative growth.
Over several months, the seedling will develop its basic leaf structure and shoot framework through the formation of auxiliary buds at leaf joints. This creates the building blocks for future branching.
Height and Branch Development
As stems elongate and the first branches develop, the young lemon plant will also quickly increase in height During this stage, the citrus tree undergoes a significant transformation.
Within 6–12 months, a seedling may reach 1-2 feet, depending on the cultivar and growing conditions. Proper lighting, nutrients, and moisture will encourage strong vertical growth and branch development during this key period.
Lemon Plant Growth Stage: Flowering Stage
After a period of approximately 12–18 months, a lemon tree will enter its flowering stage when conditions are right for reproduction. This marks an important milestone, as flowering leads to the production of lemons.
Signs a Lemon Tree is Ready to Flower
There are a few telltale signs that a young lemon tree is ready to flower:
- It has attained a height of 2-4 feet
- New growth shows more spacing between internodes
- The tree appears stronger and less leggy
- Leaf size is fully developed
Once these visual cues appear, seasonal factors will trigger flowering.
Flower Production
The primary environmental triggers for flowering are shorter days and overnight temperatures below 55°F. When winter ends and days start lengthening, flower buds will form in leaf axils.
Within 4-6 months, clusters of small, fragrant white flowers will blossom. Lemon trees are self-fertile, so they only need one tree for pollination. Bees are often required, however, to transfer pollen between flowers.
Pollination
Bees transfer pollen from anthers to stigmas, enabling fertilization. Each flower may produce 1–3 lemon fruits if it is pollinated. This happens when fruit set occurs. Unpollinated flowers will fall off within days.off within days.
Lemon Tree Fruit Stages
Once flowers are pollinated, the lemon plant shifts its focus to fruit development and maturation over the next 9–10 months.
Fruit Growth
After pollination, the ovary of the flower starts developing into an immature lemon fruit known as a ‘green fruit.’ Over several weeks, it will steadily grow in size as cells multiply.
Proper watering and nutrients are crucial during this phase of rapid cell division and expansion when you grow a lemon tree. Young lemon fruits may fall off if environmental factors stress the tree.
Ripening Process
As fruits enlarge and change color from green to greenish-yellow, they are undergoing internal ripening. Acids and sugar levels increase significantly as starches convert to simple sugars.
Ripening is influenced by warmer summer weather and may take 2–3 months total. Fruits ready for harvesting and eating will be bright yellow with thick rinds.
Harvesting Lemons
Lemons are ready for harvest from trees once they have turned completely yellow. Their mature lemon skins should feel firm yet slightly flexible when gently squeezed. Fruits can be plucked by hand at this stage.
Some growers may leave a portion of the crop on trees to continue ripening to enhance sweetness and juice content. Regularly harvesting ripened fruit from fruit trees like Meyer lemon also encourages more flowers and future yields.

Lemon Tree Dormancy and Winter Care Stage
As climates transition to fall and winter, the lemon tree enters a period of dormancy to withstand colder temperatures. Proper care is needed at this stage.
Preparing for Dormancy
Before dormancy, it’s important to harden off trees by withholding water slightly. This helps them better tolerate drought and cold. Prune back excessive new growth to maintain a tree structure appropriate for its surroundings, especially for fruit trees like lemons.
Overwintering in Cold Climates
Trees grown in USDA zones 9 and cooler require protection. Apply winter mulch around the base of your citrus tree in late fall to insulate the roots. In very cold areas, bushes may need wrapping, shade cloth, or potting for the season.
Pruning in Winter
Once trees are fully dormant, pruning can be done to open interior canopies, improve airflow, and shape bushes. Sanitize pruning shears between cuts to avoid spreading disease. Large cuts should be sealed.
Proper dormancy preparation ensures lemon trees are healthy coming out of winter to flower and produce fruit again during the next growth cycle.
Checking soils and pruning at this stage supports a continued lemon tree’s growth and fruit production in the long term.
Lemon Tree Annual Growth Cycles
Lemon trees undergo annual growth cycles that repeat each year. Understanding these patterns is important for optimal cultivation and yields.
Understanding the Lemon Tree’s Life Cycle
On average, lemon trees progress through these main growing stages each year. This includes Meyer lemon trees.
Winter dormancy lasts from November to February. Bud breaks and new growth occur from March to May. Flowering occurs from May to June. Fruit development occurs from June to December. Winter pruning and dormancy occur from November to February.
Slight variations occur depending on the cultivar and regional climate zones.
Maximizing Fruit Production Each Year
Proper care at key times maximizes lemon growth stages and crop loads. Winter pruning shapes trees for airflow and sunlight.
Fertilizing in spring supports flowering. Throughout the summer, regular water keeps fruits growing large. The fall harvest extends ripening.
Tips for Different Climate Zones
Adjustments may be needed in very hot, cold, or dry areas. For example, in coastal California, trees grow year-round. In contrast, trees further inland take a winter rest.
Desert-hardy lemon tree varieties need infrequent irrigation. Regular watering is needed for lemon trees grown elsewhere.
Optimizing Growth at Each Stage
Certain growing practices enhance lemon trees at each specific stage:
Watering Needs
When fruits are forming through winter dormancy, trees require steady moisture. During winter, while growing a lemon tree, only provide enough water to keep the soil from cracking but avoid soggy conditions.
Sunlight Requirements
Most citrus plants need at least 6 hours of direct sun daily for healthy growth. Locate trees in very sunny spots if possible. Protect transplants from too much afternoon sun while they are establishing.
Fertilization
Lemon trees, including Meyer lemon trees, are heavy feeders. A balanced citrus fertilizer works best when applied during budding, leaf out, flowering, fruit set, and nutrient export in the fall or winter. Too much nitrogen hinders flowering.
Pest and Disease Management
Common issues include aphids, scale, mealybug mites, rust mites, and fungal diseases. Prevent problems by choosing resistant varieties when available and keeping trees robust through proper care practices.
It is necessary to identify and give proper treatment to lemon tree pests and diseases.
Pruning Techniques
Selective pruning of the Meyer lemon tree encourages branching and maximizes sunlight penetration. Winter is the best time for significant structural pruning, allowing pruned areas time to heal before new growth emerges.
By customizing care like watering, sunlight exposure, feeding, and pruning to complement each stage, gardeners can help lemon trees realize their full fruiting potential through optimum lemon growth stages.
FAQs About Growth Stages of Lemon Tree
How long until a lemon tree bears fruit?
A healthy, vigorously growing lemon tree will typically flower and produce its first small harvest within 12–18 months of planting a seed or young nursery tree.
The larger the tree is transplanted, the sooner it may fruit. Seed-grown trees may take 2–3 years to bloom.
What temperature triggers flowering?
Shortened winter daylight hours combined with overnight lows under 55°F are the primary environmental triggers that stimulate flower bud formation in lemons.
Once spring arrives with lengthening days and warming nights, flower clusters develop rapidly.
When Should I Prune Back New Growth?
The best time for structural pruning is during winter dormancy, when trees are not actively growing. This gives pruned areas time to heal before the resumption of growth in the spring.
Light tip pruning can also be done after the initial harvest to encourage bushier growth.
How Do I Protect Lemons in Winter?
Trees grown in colder hardiness zones may need winter mulching, fabric wrapping, or potting, depending on predicted lows.
Checking soil moisture is also important, as both overly wet and dry soil can damage roots during dormancy. Proper preparation helps trees survive until warmer weather triggers a new growth cycle.
Conclusion
Understanding the typical growth stages that lemon trees progress through is key to their successful cultivation. It also maximizes fruit production year after year. Growth may vary slightly depending on climate zone and variety specifics.
But most lemon plants will generally follow the same pattern of germination, vegetative growth, flowering, fruit development, and dormancy.
Home growers can support healthy lemon growth stages and large, tasty annual harvests. They can do this by tailoring care practices like watering, fertilizing, pruning, and protection to match what the trees need during each phase of their lifecycle.
With proper cultivation focused on the tree’s current growth stage, even novice gardeners can enjoy bountiful crops of juicy, vitamin-C-packed lemons.
