Interplanting is the practice of planting a fast-growing crop between a slower-growing one to make the most of your garden space. It is also known as intercropping, which has the same definition of interplanting.
When you Interplant flowers and vegetables, it lets you grow different kinds of crops and minimizes the space where weeds can grow. Intercropping enables you to boost the health of all plants because it can enhance soil fertility and cooperation among different plants. The act of intercropping is an old-fashioned method that modern gardeners have begun to embrace.
An example is to sow a vegetable seed such as lettuce seeds between broccoli plants; the lettuce will grow happily in the space and shade provided by the broccoli plants.
One excellent method is to sow mesclun seeds around tomato seedlings so that it becomes possible to harvest salad greens while waiting for tomato plants to start producing.
Types of Intercropping
Intercropping, which is common in French intensive gardening, can lower the amount of pests in your garden in a few ways. Some are chemical repellents that confuse and dissuade pests from entering the area. Others create a physical barrier so the pest can't get to the other plant. Trap cropping (technically another interplanting) encourages pests to gather. Parasitic wasp host plants give food and shelter to parasitic wasps searching for pests, while predator increase gives beneficial insects food and lets them then seek out pests.
There are a few types of intercropping, by definition:
- Row Planting: When you have at least two types of vegetable with at least one in rows.
- Mixed Intercropping: Otherwise known as basic interplanting, involves mixing crops in any available space when you plant two crops together and do not use rows, such as when you have two different sized plants.
- Relay Planting: When you sow a second crop in time to mature after a first crop has produced.
Considerations for Successful Interplanting
Intercropping does take some planning to execute it successfully. Take a peek at the growing requirements of the plants you are putting in, first of all.
When planning your intercropping, look at the growth rate. Vegetables that root deeply like carrots, tomatoes, and parsnips can go well with more shallow veggies such as lettuce, broccoli, and potatoes.
The shade is another factor to take into consideration when planning to intercrop. Tall and broad-leaf crops can have lettuce, spinach or celery underneath. Alternate spring, summer, and autumn crops so you can successively harvest different veggies.
Certain plants can also help your garden repel pests. Think of cabbage, pumpkins, and marigolds, or basil, asparagus, and tomatoes.
