Planning Succession Planting: Heavy Feeders, Moderate Feeders, and Light Feeders

What Is Succession Planting?

Succession Planting refers to the practice of growing different crops on the same plot of land within a single growing season. For example, if you harvest potatoes in the spring and then immediately sow spinach in the same bed, that is succession planting. A well-thought-out plan helps you make the most of your growing space throughout the entire growing season.

With the right planning, it’s entirely possible to harvest fresh vegetables from your own garden almost all year round. Still, nature remains unpredictable: while good planning is the foundation, flexibility is key in gardening. It can always happen that plants grow poorly, get sick, or die. In such cases, even the best planning is of little help—you have to learn to adapt to the circumstances.

In addition to succession planting, you should also aim to make your garden beds as varied as possible over several years. The rotation of different crops over several years is called crop rotation. You can find more information on crop rotation in the vegetable garden here.

The Changing Face of European Gardening: Longer Seasons, New Challenges

Across Central Europe, the growing season traditionally spans from April to November—but its duration has been increasing for decades. While it lasted fewer than 200 days in the 1960s, it rose to over 220 days by the 2010s. In 2024, it reached a record 248 days (Statista, 2025). Similar trends are visible in the United Kingdom, where the growing season has extended by nearly a month compared to the mid-20th century.

While these extra growing days seem encouraging at first glance, they are a direct consequence of climate change. This trend brings a suite of new challenges to the modern gardener:

• Increased Volatility: Heavier rainfall and unpredictable late frosts.
• Environmental Stress: Extreme droughts, resource scarcity (particularly water), and a decline in native pollinator species.

Regional Nuances: From the North Sea to the Mediterranean

While Northern and Central Europe benefit from a longer warmth window, the shift in Southern Europe is more complex. In regions like Spain or Italy, extreme summer heat often causes plant growth to stall in July and August. Gardeners there are increasingly relying on "shoulder seasons"—the early spring and mild autumn—to secure their harvests and avoid the peak summer droughts.

Strategic Planning for a Resilient Garden

Despite these challenges, the current window offers a prime opportunity to cultivate a diverse range of crops. During the peak summer months, conditions are now reliably warm enough for heat-loving favorites like tomatoes, eggplants, squash, and peppers. As these are harvested in the fall, the lengthened autumns in the UK and Central Europe provide a stable window for winter crops—such as kale, leeks, or hardy salads—to establish themselves in your succession plan.

To succeed in this changing environment, precision is key. When designing your vegetable garden, you should carefully coordinate the optimal growing times for each cultivar. By planning with foresight, you can turn the challenges of a longer season into a productive, year-round harvest.

Benefits of Succession Planting in the Vegetable Garden

• Maintaining soil fertility: By strategically alternating between heavy-, moderate-, and light-feeding plants, you prevent the soil from becoming depleted.
• Year-round planting in your beds: If you plan a succession plan for the entire year, your beds will never lie fallow. This promotes soil life while protecting the soil from erosion and compaction.
• Maximizing space utilization: There are no unused gaps before or after a main crop. Especially when combined with mixed cropping, this allows you to make the most of your available space. Learn how to plan mixed cropping in your vegetable garden here.

How to Do a Good Succession Plan

For effective succession planting, alternate between different crops in your beds: follow a moderate- or low-nutrient crop with a high-nutrient main crop. The main crop usually stays in the field the longest. Pre- and post-crops have a shorter growing period and must be adapted to the temperatures. After the sequence of pre-, main, and post-crops, the soil benefits from a break. For this, you can sow a cover crop that covers the soil but does not deplete its nutrients. This improves soil health.

The main crop can be either a summer or winter crop. In our climate, we usually plant a heat-loving main crop like tomatoes or zucchini in our home gardens during the summer and plan around that. To grow your own vegetables year-round, you can also plant winter main crops like cabbage. You can find more information about growing vegetables in winter here. To keep track of everything, it makes sense to note the sowing dates for the different types of vegetables in a calendar. That way, you’ll always know when to start growing seedlings or sowing seeds in the vegetable bed.

About Heavy Feeder, Medium Feeder, and Light Feeder

These three terms describe a plant’s general nutrient requirements. Of course, the concept of heavy, moderate, and light feeders does not fully capture the needs of individual plants. Many plants have specific requirements regarding the composition of the nutrients they receive from fertilizer. However, the division into these three categories provides a rough overview and also serves as a guide for garden bed planning. Here you will find a table summarizing heavy feeders, moderate feeders, and light feeders.

Heavy Feeders, Moderate Feeders, Light Feeders: Soil Preparation & Fertilization

Depending on the plant’s nutrient needs, you may need to prepare your garden bed so that enough nutrients are available to the plant throughout the growing season. With the no-dig method, you prepare your garden beds once a year with compost to last the entire season. Alternatively, you can also fertilize your garden beds depending on what you’re planting. Here are some tips on soil preparation and fertilization:

• Heavy feeders require the most nutrients and need a balanced soil environment. For them, simply applying liquid fertilizer a few times during the growing season is usually not enough. To achieve optimal results, you should prepare your heavy-feeder bed before planting the plants. Compost or a green manure crop with nutrient-enriching plants works well for this. You can find out how to improve your garden soil easily and naturally in the related article.
• Moderate feeders are not quite as demanding as heavy feeders and do not require any extra bed preparation. They can, for example, be grown in a bed where heavy feeders were planted the previous year. A few applications of liquid fertilizer spread out over the summer are usually sufficient to help these plants reach their full potential.
• Light feeders are generally defined as plants that have no special requirements regarding soil nutrient content and can thrive with very few nutrients. These plants often require no additional fertilization at all.
