April marks the exciting transition when your vegetable garden truly comes to life. As soil temperatures rise and the threat of frost begins to fade in many regions, this month offers the perfect opportunity to get your hands dirty and lay the foundation for a great harvest.

With longer days and warming temperatures, April is prime time for both direct sowing and transplanting a wide variety of vegetables. Whether you’re a seasoned gardener or trying your hand at growing food for the first time, this month’s activities will set the stage for months of fresh, homegrown produce.

Let’s explore what vegetables you can sow and plant in April in your garden and how to give them the best start for a successful growing season.

Seed-starting indoors

If you’re new to seed-starting, you may want to read up and learn about all the necessary steps and equipment. Let’s have a look at what can be sown indoors in April:

Leek

Seed-starting in January: summer leek

Sow winter leek indoors now.  I either sow 2 – 3 seeds per small pot, or I take a larger container and sow them in rows that I will be thinning later.

Brassicas

Although we can plant the first batch of brassicas like broccoli, kohlrabi, cauliflower, white and red cabbage outdoors now, we should still sow a second batch indoors. That way, we can transplant them outdoors several weeks from now and have a continuous harvest of brassicas instead of one overwhelming flood of harvest.

Seeing that those second batches will be outside in summer, we may have to choose late instead of early varieties.

Lettuce

Like with cabbage, the second round of lettuce-starting has begun! Now, however, we want to choose varieties that like warmer weather, like, for example, iceberg and oak leaf lettuce.

Tomatoes

Bush tomatoes: easy for beginners

If you haven’t seed-started tomatoes for outdoor planting already, mid-April is the latest time to do so. Sow several seeds per pot and thin them later.

Cucurbitaceae

Cucumbers

The family of Cucurbitaceae consists of cucumbers, zucchini, melons and pumpkins, and they can all be seed-started indoors in April. None of them, however, takes thinning very well and

Vegetables we can sow outdoors in April

Broad beans

The beginning of April is the latest time to sow broad beans. They are very tolerant of low temperatures and can even withstand light frosts, which is why they don’t need protection against the cold.

Peas / Sugar peas

There are early varieties that can be sown outdoors mid to end of March. Just remember that peas are climbers and therefore install a trellis or net between the rows.

Carrots

Again, we’re talking early varieties here. If you planted onion bulbs in autumn, sow the carrots in the rows between the onions. That way, carrots and onions will protect one another from harmful pests.

Radishes

Carrots need quite some time to germinate, and it’s difficult, therefore, to weed the rows. A trick to still see where the carrots have been sown is to mix radish seeds between the carrot seeds. Radishes need only a few days to germinate and then not only show us the row but are a yummy vegetable for salads or as a ferment.

Lettuce

Contrary to the varieties we start indoors now, lettuce we sow outdoors in April has to be very tolerant against cold temperatures, like Asia lettuce. If we mix the early varieties we sow now and the later varieties we seed-start indoors, we can continually harvest different kinds of leafy greens. This method of sowing vegetables every 3 – 4 weeks is called succession planting which not only ensures a continuous harvest but also that the soil in our patches is always covered.

All lettuce varieties germinate in light only. Do not cover them with soil!

Rocket salad

is an easy one! Sow it, harvest he leaves, and when you let it bloom, it will spread itself.

Spinach

Spinach is almost a no-brainer: sow it, cover it with winter protection fleece and just let it grow. It’s usually quite tolerant of the cold and will grow well under protective cover.

Beetroot

Beetroots

Although you can seed-start beetroot indoors, that’s only advisable when you have a small garden or want to grow just some of them. In our family, we need plenty of beetroot for salads, pickles, fermented or cooked, and that’s why I sow them directly in April.

Salsify

Salsifies need a deep, loose soil to grow long, straight roots. A patch where potatoes grew the year before would therefore be ideal.

Planting outdoors

Before we plant anything outdoors, it’s important to harden the seedlings off by gradually exposing them to outdoor temperatures. Start by putting your plants outside or in the greenhouse for 2 – 3 hours at first and prolong that time over a week before transplanting.

Lettuce

The lettuce that we started in February or March is now ready for transplanting outside. Make sure that the seedlings are not planted too deeply, or they may rot. As a rule of thumb, put them into the soil as deep as they were in the pot.

Brassicas

All early brassica seedlings like kohlrabi, early Savoy cabbage and cauliflower as well as white and red cabbage, can be planted outdoors in April. Leave plenty of space between the seedlings so that you can plant celery in between later. Cabbage and celery are great companions in the patch and repel each other’s pests.

Leek

Plant leeks between the cabbage rows. That way, you not only make the best use of space here, seeing that cabbage grows on the ground and leek on the “first floor”, but they also deter pests from one another. For best protection, however, cover them with a pest protection net.

Garlic

Garlic bulbs

I usually plant garlic bulbs in autumn, but you can still do so now. Hop over here to get a detailed guide on how to best plant garlic.

 Onions / Shallots

Like garlic, onions and shallots can be planted now. Either plant small bulbs you can buy at the nursery or the seedlings you’ve started indoors earlier that year.

Potatoes

In my hardiness zone 7b, I don’t plant potatoes before the end of April. Considering that our last night frosts can happen until mid-May, the end of April is perfect for putting the pre-sprouted potatoes in the ground. When the shoots start looking out of the soil, the worst weather will be over.

The gardening season has officially started! Time to dig in the dirt!
