Sow these 8 vegetables in April for a bumper homegrown harvest before it's too late
April is a peak sowing month for vegetables as the soil starts to warm
April is a key moment in the garden and requires a well-thought-out to-do list — particularly when it comes to sowing hardy vegetables.
"In April temperatures are rising, the soil is beginning to warm, and there’s still a valuable window to sow veg varieties that will feed you right through summer and into autumn," Charlotte Denne, an award-winning horticulturist and co-owner of Kent Wildflower Seeds, explains.
"Success now comes down to choosing varieties that establish quickly and make the most of early-season moisture, setting the foundation for a productive growing season ahead."
April is a crucial month for vegetable gardens as the soil begins to warm, allowing for the direct sowing of hardy crops such as beetroot, lettuce, spinach, carrots and radishes.
Tender crops like sweetcorn, runner beans and tomatoes can also be started indoors or under cover.
"Overall, April sowing is about momentum, getting crops underway as the weather begins to improve and setting yourself up for a continuous harvest rather than a single glut later in the season," Charlotte continues.
Here are eight crops to sow in April before things really heat up this spring.
Carrots
"Carrots do best with a soil temperature above 40 degrees, which April provides. Better germination and summer-long care-free harvesting are two of the great benefits of April planting," Matthew Wilson, professional gardener and CEO of Handy Gardeners, tells us.
Tip: Carrots prefer direct sowing into loose, stony-free soil. A consistent moisture level in the seedbed will ensure consistent germination. Thin seedlings early on to prevent misshapen roots due to overcrowding.
Tomatoes
Tomatoes are best for a greenhouse or sunny spots. "April is really your last call for sowing tomatoes from seed if you want a decent crop this summer," Charlotte tells us. "I tend to go for unusual or heritage varieties from She Grows Veg. My favourites are richly coloured and storage tomatoes."
"Make sure you harden off your seedlings well before moving them!" adds Lotte Berendsen, plant expert from PlantIn-plant care app.
Tip: Sow in warmth (around 18–20°C) and don’t rush them outside as they need strong light and protection from late frosts.
Squash
Including courgettes and tromboncino types."These are incredibly productive and perfect for UK summers if started now," Charlotte explains. "Varieties like tromboncino are particularly useful if you have limited space, as they can be grown vertically, saving space."
Tip: Sow seeds on their side in pots to prevent rotting and only start them a few weeks before planting out. Note that they grow fast and hate being checked.
Beetroot
"Consider beetroot for your April planting list to receive a guaranteed crop in a short period of time," Matthew explains. "All parts of beetroot are usable, which furthers versatility."
Charlotte adds: "Beetroot thrives in warming soil and is one of the most dependable crops, even in our unpredictable seasonal conditions. It’s also wonderfully versatile, as both the roots and young leaves can be harvested and eaten."
Tip: For a continuous harvest, use a staggered sowing schedule. Well-spaced seedlings will ensure roots have enough swelling room.
Radishes
"April is the perfect time to plant radishes," Matthew explains. "Their maturation period is extremely fast, and they can be ready to harvest in just a few weeks. This trait is perfect for beginner gardeners, as they can see a quick harvest and result."
Tip: Be sure to harvest at the right time! Leaving radishes in the ground for too long can result in a woodier or spicier radish.
Lettuce and salad leaves
"Lettuce does not like heat and excessive sunlight, which is why April is a great time to sow your Lettuce seeds," Lotte explains. "As Lettuce grows very fast, it can be harvested before summer, which helps to prevent heat stress and bolting, which is common in Lettuce plants."
Charlotte adds: "Salad leaves are one of the easiest wins for April sowing, establishing quickly in mild conditions and providing repeated harvests. To elevate a standard mix, it’s worth weaving in a few wild edibles: salad burnet (Sanguisorba minor), a hardy perennial with a fresh, cucumber-like flavour and nutrient-rich leaves, and kidney vetch (Anthyllis vulneraria), whose young leaves add a subtle citrus note."
Tip: Mix these more unusual edible varieties with conventional salad crops to keep your harvest varied, visually interesting, and more nutrient-dense than standard leaf mixes alone.
Peas
"April is the beginning of the growing season for peas," Matthew explains. "This is the ideal time to plant them because they prefer cooler climates. A strong initial growth before it gets hot is critical to their overall growth. They are great vertical growers."
Tip: Protect the young plants from the elements while they are establishing. Early support is useful for establishing control over the growing area and the vertical growth of the peas.
Purple sprouting broccoli (for next year’s harvest)
"This is a slightly overlooked April sowing, but it’s a brilliant one for forward planning," Charlotte explains. "You’re sowing now for a very early spring crop next year."
Tip: Sow in modules and transplant once sturdy; note that generous spacing is key to good airflow and strong plants.
