Timing Makes All the Difference: Cherokee Purple Tomato Growing

Cherokee Purple Tomatoe Growing

Cherokee Purple represents something increasingly valuable in modern gardening: a properly flavourful tomato with genuine character. Whilst commercial breeding has prioritised shelf life and uniform appearance, heritage varieties like this one have retained the rich, complex taste that tomatoes should actually have. I’ve found the flavour genuinely different from standard varieties, with a smoky sweetness and low acidity that works brilliantly in salads and sandwiches.

Beyond taste, growing this variety connects you to seed-saving traditions and genetic diversity. Cherokee Purple is an heirloom variety, meaning its seeds breed true when saved properly. You’re not dependent on purchasing new seeds each year, and you’re actively maintaining horticultural heritage that might otherwise disappear. The variety dates back over a century, originally grown by Cherokee people in Tennessee before being introduced to wider cultivation. For more on this, see our guide on smart planting partnerships that actually boost your onions.

The fruit itself is distinctive: large, beefsteak-style tomatoes weighing 200-350g when well-grown, with dusky purple-brown shoulders and brick-red flesh. The colour comes from anthocyanins, the same compounds found in blueberries and blackcurrants, which have antioxidant properties. When you slice into a ripe Cherokee Purple, you’ll see greenish gel surrounding deep red flesh, a characteristic that initially surprises new growers but indicates proper ripeness.

From a practical standpoint, these tomatoes yield generously when conditions suit them. A healthy plant in a greenhouse or polytunnel can produce 4-6kg of fruit over the season, with individual trusses carrying 4-6 large tomatoes. That’s substantial enough to justify the space and effort involved, particularly given the premium prices heritage tomatoes command at farmers’ markets if you have surplus to sell.

Getting Started with Cherokee Purple Tomatoe Growing

Seed Starting and Early Care

I start Cherokee Purple seeds in late February or early March, which gives plants sufficient time to mature before our unpredictable summer arrives. This timing is earlier than many gardeners expect, but it’s necessary for a variety that needs 80-90 days from transplanting to first harvest. I use modular trays with peat-free multipurpose compost, sowing seeds individually about 1cm deep and keeping them at 18-21°C until germination occurs, usually within 7-10 days. You might also find timing makes the critical difference with crop rotation helpful.

Once seedlings emerge, temperature management becomes important. They need bright light and slightly cooler conditions around 16-18°C to prevent legginess. I’ve watched too many early-sown tomatoes become stretched and weak because they sat on warm windowsills without adequate light. A heated propagator with a thermostat and supplementary grow lights makes a real difference if you’re serious about getting strong plants established early.

When true leaves appear (the second set, which look like proper tomato leaves rather than the initial seed leaves), I pot up into 9cm pots using good-quality compost. This intermediate stage allows root development without wasting space in larger containers. The plants stay in these pots for 3-4 weeks, receiving liquid feed at half-strength once they’ve established, before moving to their final positions.

Planting Location and Soil Preparation

Cherokee Purple performs best under protection in most British regions. I grow mine in a polytunnel, but greenhouses work equally well. Outdoor cultivation is possible in sheltered southern locations, particularly against south-facing walls, but you’ll face challenges with our variable summers. The variety needs consistent warmth and protection from heavy rain, which can split the ripening fruit and encourage blight.

Soil preparation matters enormously for these vigorous plants. I incorporate well-rotted manure or garden compost at about one bucketful per square metre several weeks before planting. Cherokee Purples are heavy feeders that demand rich soil with good moisture retention, but adequate drainage to prevent waterlogging. The ideal pH sits between 6.0-6.8, slightly acidic to neutral. If you’re growing in containers, use at least 30-litre pots filled with quality compost mixed with additional perlite or vermiculite for drainage.

I don’t rush planting out, even under protection. The soil needs to warm to at least 10°C, which typically occurs in late April or early May in southern regions, later further north. Planting into cold soil shocks the roots and sets plants back significantly. I use a soil thermometer to check before making the move, and I’ve found waiting an extra week produces better results than planting too early.

Support Systems and Training

Cherokee Purple grows as an indeterminate (cordon) variety, meaning it continues growing upwards and producing fruit throughout the season rather than stopping at a predetermined height. This growth habit requires proper support from the outset. I use sturdy bamboo canes at least 1.8m tall, secured to horizontal wires, or purpose-made tomato spirals which make training easier.

Training involves removing side shoots that emerge between the main stem and leaf branches. This process, called pinching out or de-suckering, concentrates the plant’s energy into fruit production rather than excessive foliage. I check plants twice weekly during active growth, as side shoots develop rapidly in warm conditions and become harder to remove cleanly if left too long. Use your fingers to snap them off when small, about 2-5cm long, which creates minimal wound that heals quickly.

As plants grow, I tie the main stem loosely to the support using soft twine or purpose-made clips. The ties need to allow for stem thickening without constricting growth. I maintain one main stem per plant, though some growers successfully run two stems from vigorous plants in large containers. By late July or early August, I stop the plants by pinching out the growing tip above the fourth or fifth truss, which allows existing fruit to ripen properly before autumn arrives.

Advanced Growing Techniques

Watering and Feeding Strategy

Consistent watering makes the difference between mediocre and excellent Cherokee Purples. These plants need regular, even moisture throughout the growing season, but particularly once fruit begins to swell. I water deeply rather than frequently, ensuring moisture reaches the full root zone which extends 30-40cm deep in established plants. Erratic watering causes problems: drought stress followed by heavy watering leads to fruit splitting, whilst constantly saturated soil encourages root diseases.

I’ve found that watering in the morning works best, allowing any splashed foliage to dry during the day and reducing disease risk. Under protection, I aim to keep soil consistently moist but not waterlogged. A simple test involves pushing your finger 5cm into the soil; if it feels dry at that depth, watering is needed. Mulching around plants with well-rotted compost or straw helps retain moisture and reduces watering frequency, particularly valuable during hot spells.

Feeding begins once the first truss sets fruit. I use a high-potash tomato feed (the type formulated for fruiting plants) at the rate recommended on the packaging, typically twice weekly. Cherokee Purples respond well to consistent feeding, producing larger fruit with better flavour. However, excessive nitrogen from inappropriate feeds promotes leafy growth at the expense of fruit and increases disease susceptibility. I’ve occasionally supplemented with foliar feeds containing calcium and magnesium when plants show deficiency symptoms, though well-prepared soil usually provides adequate trace elements.

Pest and Disease Management

Blight remains the primary concern for tomato growers in Britain, and Cherokee Purple shows typical susceptibility. The fungal diseases causing tomato blight (Phytophthora infestans, the same organism affecting potatoes) thrive in warm, humid conditions with leaf wetness. Growing under protection dramatically reduces risk by keeping foliage dry and improving air circulation. I ensure adequate spacing between plants, at least 45cm apart, and remove lower leaves once plants establish to improve airflow around the base.

Preventative measures work better than reactive treatments. I monitor local blight alerts through online services that track weather conditions favouring outbreaks. When conditions turn risky, I reduce overhead watering entirely and ensure maximum ventilation. Some growers use copper-based sprays or biological treatments preventatively, though I’ve found cultural controls adequate under protection.

Whitefly and aphids occasionally colonise plants, particularly in enclosed environments. I introduce biological controls like parasitic wasps early in the season before populations explode. Yellow sticky traps monitor pest numbers and catch some adults. For serious infestations, insecticidal soap sprays work effectively without harming beneficial insects when applied carefully. Regular inspection catches problems early, when they’re manageable with minimal intervention.

Pollination and Fruit Set

Under protection, pollination sometimes needs assistance since natural pollinators have limited access. Cherokee Purple flowers are self-fertile, containing both male and female parts, but pollen transfer still requires movement. I gently tap or shake flowering trusses mid-morning when conditions are warm and dry, which releases pollen and improves fruit set. Some growers use electric toothbrushes held against the stem behind flowers, mimicking bee vibrations, though I’ve found hand-shaking adequate.

Temperature affects pollination success significantly. When night temperatures drop below 10°C or day temperatures exceed 32°C, pollen viability decreases and fruit set suffers. Our British summers rarely cause heat-related problems, but cold nights in early or late season can prevent proper pollination. I delay planting until stable temperatures arrive and use fleece over plants during unexpected cold snaps to maintain warmth.

Regional and Seasonal Variations

Southern counties from Cornwall to Kent enjoy the longest growing seasons and most reliable sunshine, making Cherokee Purple cultivation more straightforward. Growers in these regions can sometimes succeed with outdoor plants in sheltered positions, particularly when positioned against south-facing walls that radiate stored heat. Even here, protection from rain during ripening improves results and reduces disease pressure.

Midlands and northern English regions need to rely more heavily on protected growing. I’ve spoken with growers in Yorkshire and Lancashire who consistently produce excellent Cherokee Purples in polytunnels, but outdoor attempts rarely ripen more than a few fruits before autumn frosts arrive. The key involves maximising the growing season through early starts under heat and maintaining protection until October.

Scotland, Wales, and Northern Ireland present additional challenges due to shorter seasons and less reliable summer warmth. Growers in these regions should definitely use greenhouse or polytunnel cultivation, potentially with supplementary heating in early and late season. Choosing the sunniest position available and selecting particularly sheltered sites helps compensate for climatic limitations. I’ve heard from Scottish growers who’ve had success by focusing on just 3-4 trusses per plant, stopping earlier to ensure existing fruit ripens properly.

Coastal regions face specific considerations. Whilst benefiting from moderated temperatures that reduce frost risk, salt-laden winds can damage plants and slow growth. Windbreaks, whether natural hedging or artificial screening, make substantial differences in exposed locations. The generally higher humidity in coastal areas also increases blight risk, making vigilant monitoring essential.

Seasonal variations matter enormously in our changeable climate. Cool, wet summers like some we’ve experienced recently delay ripening and increase disease pressure. During challenging seasons, I focus on disease prevention, ensure maximum ventilation, and accept that yields may fall below optimal years. Conversely, rare hot, dry summers require increased attention to watering and may need shading if greenhouse temperatures become excessive.

In Practice: What Actually Works

In practice, many growers find that Cherokee Purple demands more attention than modern hybrid varieties but rewards that investment with superior flavour. The variety seems particularly sensitive to inconsistent growing conditions. Plants subjected to water stress, temperature fluctuations, or inadequate feeding produce acceptable but unremarkable fruit, whilst those receiving consistent care develop the complex, rich flavour the variety is known for.

Harvesting at the right stage makes considerable difference to eating quality. Cherokee Purples should feel slightly soft when gently squeezed and show deep colouration, though the shoulders often remain greenish-purple even when ripe. Many growers initially pick them too early, expecting uniform colour. I’ve learned to wait until fruit yields to gentle pressure, which indicates the flesh has developed full flavour and the proper texture. Underripe Cherokee Purples taste bland and acidic, nothing like the sweet, complex flavour of properly ripened fruit.

Storage presents challenges since these thin-skinned tomatoes don’t keep as long as commercial varieties. Most growers find they last about 5-7 days at room temperature once picked, less in warm conditions. I never refrigerate them, as cold temperatures destroy flavour compounds and create mealy texture. For surplus harvests, making sauce, chutney, or freezing for winter soups works better than attempting long-term fresh storage.

Many growers companion plant Cherokee Purples with basil, marigolds, or nasturtiums, believing these combinations deter pests or improve growth. Whilst hard evidence remains limited, I’ve found basil particularly useful as a sensory indicator. If basil thrives alongside the tomatoes, conditions suit both plants. When basil struggles, it often signals problems with temperature, watering, or soil quality that will soon affect tomatoes as well.

Experienced growers often run comparison trials, growing Cherokee Purple alongside other heritage varieties like Brandywine, Black Krim, or Green Zebra to determine which performs best in their specific conditions. These comparisons reveal that whilst Cherokee Purple generally produces reliably, some gardens or growing environments favour different varieties. There’s no substitute for direct experience in your own location with your particular soil and microclimate.
