Companion Planting With Pumpkin: Good and Bad Companion Plants

Planting Pumpkins in the Garden: Location & Soil

Pumpkins are part of the gourd family (Cucurbitaceae). In addition to Pumpkins, the cucurbitaceae family also includes Cucumbers, melons and zucchinis. However, good and bad plant companions differ within the various species of a family. The zucchini, for example, has different good companions than the pumpkin.

These plants originate from Central and South America, so they are heat-loving crops. Therefore, choose a sunny but sheltered location for your pumpkin plants. The soil should be rich in humus and nutrients, as pumpkins are Heavy Feeders. Whether the soil is loamy, clayey or sandy is relatively unimportant for pumpkin plants. The only important thing is that the soil should not dry out.

Mixed Cultivation With Pumpkin: Good and Bad Companion Plants

Pumpkins are particularly suitable as ground cover in a Mixed Culture. Within one season, they can cover an area of up to three square meters and provide shade with their large leaves. As a result, less water evaporates from the soil and the soil is protected from wind and water erosion.

• Planting nasturtiums and pumpkins together is also a good idea. In general, nasturtiums are ideal for mixed cultivation. It keeps so-called pests away from its companions. Most pests prefer to eat nasturtium plants. This also applies to normal garden cress.
• Kohlrabi also goes well next to pumpkin. Kohlrabi is a medium feeder and therefore goes very well next to the heavy-eating pumpkin. In addition, kohlrabi plants develop deeper roots than pumpkin plants, so there is no competition for nutrients.
• Growing garlic in a mixed crop with pumpkin keeps pests and diseases out of your bed. The intense scent will drive away some hungry insects such as aphids.
• Herbs such as lavender, marjoram, oregano, peppermint and hyssop are good companions for pumpkin plants. The essential oils of most herbs keep pests away, while their flowers attract beneficial insects such as pollinating insects. In this way, they ensure better plant health in the bed. Some herbs are also said to improve the taste of vegetable plants.
• But other flowers such as chamomile and marigolds are also good plant companions. Chamomile plants use up a lot of calcium in the soil. This is good for pumpkin plants, as these tend to like low pH values due to their tropical habitat. Marigolds keep hungry nematodes away from the soil and promote the growth of pumpkin plants.

These Are Bad Companion Plants for Pumpkin Plants:

• Planting onions and pumpkins together can have advantages, as onions keep field mice away. The pumpkin plants are happy about this, as they have very sensitive roots. However, pumpkins and onions have different water requirements, which is why they do not complement each other so well. One possibility, however, would be to place the onions a little away from the pumpkin (about 1.5 m/1 yd away) and plant them as a border.
• Potatoes and pumpkins can be planted next to each other. However, the pumpkin has a very high water requirement and can therefore favor the infestation of the potatoes with brown rot. Depending on whether this is a problem in your garden, you can decide whether you want to plant these crop companions together.
• It is also possible to plant zucchinis and pumpkins together. However, both zucchini and pumpkin plants are susceptible to powdery mildew. If this is already a major problem in your beds, you should not choose this combination. The same applies to cucumbers and melons. In addition, all three plants are shallow-rooted and heavy feeders. This means that the soil is heavily depleted.
• Plants from the shade family, such as tomatoes, peppers and eggplants, should not grow next to pumpkins. These plants are also heavy feeders and susceptible to mildew.
• Cabbage plants are also heavy feeders and should be planted next to plants with lower nutrient requirements.
• Planting dill and pumpkin together is not a good idea. Dill inhibits the growth of your pumpkin plants.

Succession Planting With Pumpkins

Pumpkin plants have a high demand for nutrients. Plant or sow after heavy feeders, medium to light feeders or a green manure. Planning a good succession plan is important to maintain soil and plant health. You can find out How to Plan Succession Planting in this article.

Suitable pre- and post-crops for pumpkins are lettuce (lamb's lettuce, Asian lettuce, winter lettuce), radishes, spinach, peas, broad beans, postelein, endive (as young plants), parsley and Jerusalem artichokes.

Crop Rotation With Pumpkin Plants

As with most vegetable plants, a cultivation break of 4 years on a bed (section) is recommended. This information should be understood as somewhat flexible. If you prepare your beds well, have not previously had any problems with severe pest or disease infestation, sow green manures and plant mixed crops, 2 to 3 years is often sufficient.

Mixed Cultivation With Pumpkin: Planting Plans for a Garden Year

We have prepared a garden year with pumpkin in mixed cultivation with suitable pre- and post-cultivation for you.

Vegetable Patch From January to April: Pre-cultivation for Pumpkin Plants

As pumpkin plants are heat-loving crops, they are only planted in the bed after the last frosts. To use your bed all year round, you can sow some cold-resistant plants in early spring: spinach, lettuce, radishes and kohlrabi . While the other crops are harvested by mid-May, the kohlrabi can remain in the bed. ,Superschmelz' is a kohlrabi variety with a relatively long growth phase. The tubers can then be harvested from July.

Planting Plan for May to September With Heat-Loving Summer Crops

Summer crops can then be planted in the bed from May. Pumpkin plants are usually grown on the windowsill and planted as young plants, as are nasturtiums, oregano and sunflowers. You can harvest earlier if you plant young plants. You can find out how to Grow and Sow Your Pumpkin Plants in this article. You can sow runner beans directly into the bed. Sunflowers that have been pre-grown and have a head start on growth will serve as a stable climbing aid. You can also sow daikon such as 'Easter greetings pink' in April/May. Daikon also grow relatively quickly and are ready to be harvested after 2 to 3 months.

Bed in winter - October to December

When the temperatures drop, the summer crops gradually die off and make room for new ones. As pumpkin plants have a high nutrient requirement, you should either sow a green manure or choose low-yielding crops, as shown here in the plan. You can sow cover crops such as peas, spinach, lettuce such as rocket, radishes and lamb's lettuce.
