When to Plant Your First Early Potatoes
The optimum time for planting first early potatoes is generally from early to mid-spring, typically between March and April in the UK. This period allows the seed potatoes to establish before the risk of severe frost has passed, yet takes advantage of lengthening days and warming soil. For the earliest crops, growers may consider chitting (pre-sprouting) seed potatoes indoors a few weeks beforehand to give them a head start.
- Plant first early potatoes from March to April.
- Chit seed potatoes indoors for an earlier start.
- Ensure soil temperatures are above 7°C for germination.
- Protect young shoots from late frosts.
- Early varieties mature in 9-12 weeks.
Choosing the right moment is paramount. While March often marks the beginning of the planting window, conditions can vary significantly across regions and from year to year. It is advisable to check local weather forecasts and soil conditions. The soil should be workable and ideally have warmed to at least 7°C (45°F). Planting too early into cold, waterlogged soil can lead to seed potato rot and poor germination.
When considering how to plant potatoes, understanding the needs of early varieties is key. These are bred for speed, maturing significantly quicker than maincrop types. This means their planting window is also narrower, and success hinges on getting them into the ground at the right time to benefit from the spring growing season without being caught by summer heat or autumn blight.
Preparing Your Seed Potatoes
Before the first early potatoes planting time arrives, preparing your seed potatoes, also known as 'seeders', is an important step. This process, called 'chitting', involves placing seed potatoes in a light, cool (around 10-15°C) environment for several weeks before planting. The aim is to encourage short, sturdy, dark-green sprouts to emerge from the 'eyes' of the potato. Chitted potatoes tend to establish more quickly and produce an earlier harvest, giving you that crucial head start for your first crop.
If you haven't started chitting, don't worry. You can still plant standard seed potatoes directly into the ground when the time is right. However, chitting is a widely recommended practice for achieving the earliest possible crops, especially for those eager to taste home-grown new potatoes as soon as possible.
The decision to plant is influenced by both the calendar and the climate.
For those who opt for growing potatoes in pots or in growing bags for potatoes, the planting time can sometimes be a little more flexible. Container growing allows for greater control over soil temperature and drainage, and pots can be moved to a more sheltered spot if late frosts threaten. This can enable planting to commence slightly earlier, perhaps in late February or early March, provided adequate protection is given.
Understanding Soil Conditions
The soil must be well-drained and free from frost. If the ground is still frozen or saturated, it is best to wait. Excessive moisture in cold soil is a primary cause of tuber rot, a common issue that can decimate early potato crops. Gently fork over the soil where you intend to plant, incorporating well-rotted compost or manure to improve fertility and structure. This prepares the ground for the seed potatoes and supports healthy root development once they are in the ground.
Optimising Planting Techniques for Early Crops
How do you maximise your chances of success when planting first early potatoes? The method you choose can significantly impact yield and maturity. Whether you're planting in the open ground, in containers, or using grow bags, the principle remains: provide the right conditions for rapid growth.
Planting in the Open Ground
For traditional garden beds, the first early potatoes planting time usually involves digging trenches about 10-15 cm (4-6 inches) deep. Space the seed potatoes 20-30 cm (8-12 inches) apart within the trench, ensuring the sprouted end is facing upwards. Then, gently backfill the soil, leaving a small ridge over the potatoes. This initial covering protects the tubers from light, which can cause them to turn green and develop solanine, a bitter toxin.
As the potato plants grow, you will need to 'earth up' – draw soil around the stems. This is done in stages, usually when the plants are about 15 cm (6 inches) tall, and again when they reach about 20 cm (8 inches). Earthing up protects the developing tubers from light, encourages more tubers to form along the buried stem, and helps prevent the plants from toppling over.
Protect young potato shoots from late frosts by covering them with fleece or an upturned pot if a cold snap is forecast.
Growing Potatoes in Pots or Bags
When growing potatoes in pots or growing bags for potatoes, the process is similar but offers more control. Start by placing a layer of compost at the bottom of the container. Arrange your seed potatoes on this layer, spaced apart, and cover with about 7-10 cm (3-4 inches) of compost. This method simplifies earthing up, as you simply add more compost to the container as the plants grow, keeping the top of the soil level with the developing foliage.
Using specialised potato grow bags is particularly convenient. They often have a flap at the bottom, which allows for an earlier harvest of the lower tubers without disturbing the entire plant. This is a fantastic method for smaller gardens or patios, enabling you to grow a decent yield in a compact space.
The success of your early potato harvest lies in timely planting and diligent earthing up.
Choosing the Right Varieties
When selecting varieties for your first early potatoes planting time, look for those specifically labelled as 'first early' or 'second early'. These are the quickest to mature, typically yielding edible new potatoes within 9 to 12 weeks of planting. Popular choices include 'Swift', 'Jazzy', 'Lady Christl', and 'Rocket', known for their speed and desirable flavour. Consider the specific conditions in your garden and your personal preferences when making your selection.
Different planting methods suit various garden sizes and conditions.
It is crucial to use certified seed potatoes. These are specifically grown and inspected to be free from diseases that could affect your crop. Planting infected seed potatoes can lead to significant yield loss or complete crop failure, making certified stock a wise investment for any gardener planning their first early potatoes planting time.
Beyond Planting: Care and Early Harvest
Once you've navigated the first early potatoes planting time and your plants are growing, attentive care ensures a successful crop. The key is to support rapid development so you can enjoy those sought-after early potatoes as soon as they are ready.
Watering and Feeding
Early potatoes require consistent moisture, especially during dry spells. While they don't like to sit in waterlogged conditions, which can lead to rot, they do need regular watering to prevent the tubers from becoming hard or developing growth cracks. Aim to keep the soil evenly moist, particularly from the time the plants start to flower, which is when the tubers are actively forming. Avoid letting the soil dry out completely and then watering heavily, as this can shock the plants.
Feeding is generally less critical for first earlies planted in well-prepared soil, especially if compost or manure was added at planting. However, a balanced liquid feed can be beneficial if the plants appear to be struggling or if the soil is poor. Apply a feed specifically formulated for tomatoes or potatoes, following the product's instructions, typically every 2-3 weeks once flowering begins.
Monitoring for Pests and Diseases
While early varieties often escape the worst of potato blight, which tends to strike later in the season, it's still wise to be vigilant. Keep an eye out for signs of blight, such as dark, water-soaked patches on leaves and stems. If detected, affected parts should be removed promptly to prevent spread. Prompt action is also needed against slugs and snails, which can damage young shoots and tubers. Barriers or organic slug pellets can help protect your plants.
Another common issue is potato blight, which can affect the foliage and tubers. While first earlies are typically harvested before the main blight season, adverse weather conditions can sometimes accelerate its appearance. Regularly inspect your potato plants for any unusual spots or wilting. Early detection and removal of affected leaves can help slow the spread.
When preparing soil for planting, consider adding a handful of bone meal to the trench to provide essential phosphorus for tuber development.
When to Harvest Your Early Potatoes
The beauty of first early potatoes is their speed. You can usually expect to harvest your first crop approximately 9 to 12 weeks after planting, depending on the variety and growing conditions. Look for the plants to start flowering; this is a clear indicator that the new potatoes are forming beneath the soil.
To check for readiness, gently scrape away some soil from around the base of a plant with your fingers or a small trowel. If the tubers are of a usable size (often described as 'new potato' size), you can begin harvesting. For an initial light harvest, you can carefully dig up a few of the larger tubers from around the base of the plant, allowing the smaller ones and the rest of the plant to continue growing. This technique is often referred to as 'robbing' the plants and provides a staggered harvest.
Harvesting at the right time ensures the best flavour and texture.
For a full harvest, you can lift the entire plant once the tubers have reached your desired size or when the foliage begins to yellow and die back naturally. This usually signals that the plant's growing energy is shifting from foliage production to tuber maturation. Carefully dig up all the potatoes, taking care not to damage them with your trowel or fork. Allow them to dry briefly on the soil surface (if conditions are dry) before storing them in a cool, dark, and well-ventilated place.
Comparing Planting Times and Methods
Deciding on the precise first early potatoes planting time involves weighing several factors, from regional climate to personal preference for early yields versus convenience. Understanding the nuances between different approaches can help gardeners achieve their best harvest.
Variations in Spring Weather
The UK's spring weather is notoriously unpredictable. While March and April are the typical planting months, a late frost can be devastating to young potato plants. This is where 'earthing up' plays a crucial role, offering some protection. For those planting in early March, especially in colder northern regions or exposed areas, a more cautious approach to soil preparation and covering may be needed. Conversely, in milder southern areas, pushing planting dates slightly earlier, perhaps late February, might be feasible if the soil is warm enough and protection is readily available.
Consider the 'last frost date' for your specific area. While difficult to predict accurately, general knowledge of your microclimate helps. If you've historically experienced frosts into May, you might favour a slightly later planting date or ensure you have robust protection measures in place.
Container vs. Ground Planting
When considering when to plant potatoes, container growing offers a distinct advantage: control. Growing bags for potatoes and large pots can be placed in a sheltered, sunny spot from late February or early March. This offers protection from the worst of the spring chill and allows the soil within the container to warm up faster than the open ground. As the plants emerge, they can be moved slightly if a severe frost is forecast. This ability to manoeuvre pots or bags means you can often achieve an earlier planting and, consequently, an earlier harvest compared to planting directly into the garden soil, which must remain undisturbed until conditions are reliably favourable.
The choice between ground and container planting affects your flexibility.
Impact on Harvest Timing
The timing of your first early potatoes planting time directly influences when you can expect to harvest. Planting in late March might yield potatoes by mid-June, whereas a late April planting could push harvest into July. For gardeners eager for the first taste of new potatoes, the earlier planting window, combined with chitting, is the most effective strategy. However, if convenience or a less demanding gardening schedule is a priority, a slightly later planting is perfectly acceptable and will still yield delicious results, albeit a little later in the season.
It's also worth noting that second early varieties, which take slightly longer to mature (around 12-16 weeks), can be planted a few weeks after the first earlies, extending the harvest period. This allows for a continuous supply of new potatoes throughout the summer months, from late spring through to early autumn.
When to Grow Potatoes: A Broader View
While the focus here is on the first early potatoes planting time, remember that maincrop varieties have a different planting schedule, typically from mid-April to May. These are grown for storage and larger yields, taking longer to mature (16-20 weeks or more). Successfully growing a range of potato types means understanding these distinct planting windows. By planning your planting for first earlies, second earlies, and maincrops, you can ensure a supply of potatoes from early summer right through to the following spring.
