Some of the gardeners that grow spinach have found that they do not do well when planted together with potatoes.
Some of these farmers believe it is because of the shallow roots of the spinach. Although the potatoes are larger than the spinach, they tend to keep their roots close to the soil.
This increases competition for water and nutrients that are close to the top soil. In addition, since the potatoes are taller they will block the much needed sunlight, making spinach have lower yields.
However, spinach benefits from the nitrogen fixing when grown together with peas and beans. In addition, the spinach will do well when grown together with most cabbage family vegies as well as strawberries.
Eggplant benefits from nitrogen fixation provided by legumes and are also good companions to potato, capsicum, spinach, as well as peeper.
In addition, when you grow beans around eggplant it will repel the Potato beetle which attack it.
To get the maximum yields you should make sure that you keep away black walnuts which are known to interfere with the eggplant growth.
Tomatoes are some of the garden staples that attracts many pests that also affect other nightshade veggies such as pepper, eggplant and potatoes.
So… it is advisable to avoid planting these plants together. When doing crop rotation, you should also remember to substitute with other plants not in this family.
Growing the same family may lead to development of too many disease causing microbes as well as eggs and larvae of common pests. Avoid growing tomatoes with cabbage family veggies as well as corn.
Strawberries are relative heavy feeders and why they appreciate beans planted around them to provide them with the nitrogen.
Since they develop sweet and soft fruits they attract a lot of pests. If you plant them together with onions, sage as well as thyme, they benefit from their pest repellent properties.
The strawberries yields are also lessened when grown together with pest prone cabbages family veggies.
Peas are leguminous plants which benefit many garden plants that require nitrogen. This is makes them good companions to all types of cabbages, carrots as well as corn.
However, peas prefer to be planted away from onions, shallots, garlic and potatoes. The garlic and onions produce chemicals retarding the growth of peas.
Dill is one of the aromatic herbs appreciated by many garden plants because of its ability to repel pests.
This plant does well when planted close to onion, lettuce and cabbage. For various reasons this plant is incompatible with tomato and carrot.
Most farmers think that growing garlic is very beneficial to all the plants because of its pungent smell that repel the pests.
Although this is very true, its ability to repel these pests does not seem be effective when it comes to some plants.
For instance, leguminous plants such as beans do not do well when garlic is around. The snow peas are greatly affected since garlic makes them to have a stunted growth and have very low yields.
However, some farmers have discovered that this can be corrected if you leave a sufficient distance between peas and garlic, allowing their roots to have a breathing space.
However this does not work when the garlic is in a patch of asparagus. The pungent smell however, will do a great job in repelling most of the pests that affect tomatoes, roses and radishes.
Rosemary is not only small and looks great but also do a very good job of attracting pollinators. These pollinators will do a great job in ensuring that the plants are pollinated thus increasing their overall yields.
The plant does well when planted around cruciferous vegetables. However, you should avoid planting them around the cucumbers.
This is because they tend to release some chemicals that hinders the growth of the cucumbers.
27. Brussels Sprouts
Brussel Sprouts are very tasty and good in salads. They have many of the same nutrients requirements as the tomatoes. This makes them compete for the same nutrients and why you should not plant them together.
In addition, they are also incompatible with strawberries. They attract the same kinds of pests. However, planting these close to dill and thyme will benefit from their insect repelling properties.
They also do well when grown together with potatoes.
Allowing enough space between plants is very important since different plants have different nutrition demands.
Remember plants that need more water and fertilizer can easily cause problems to other plants that are less nutrient demanding.
If you want these incompatible plants to do well, provide extra space between them.
Another tip that can assist you in growing incompatible plants together is taking note of the allelopathic plants.
Allelopathic plants tends to impede growth and development of other plants because they release certain chemicals that are harmful to the other plant.
Some of the most common allelopathic plants are weeds although there are many others that produce these effects on the competing plant species.
Although there are many discrepancies between what different farmers find good and bad companions for their plants, we have listed some of the common combinations that have been observed by more than one farmer.
However, you can find incompatible plants doing well depending on weather, soil type, nutrients availability as well as deficiency or even the planting or growing seasons.
For example, when there is a deficiency of certain nutrients some plants with similar needs will compete to get the most of what is available.
This may lower the yields of one of the competitors. This may also apply where the water is limited. If there is plenty of water both plants can coexist happily.
For you to be the best gardener, you must learn to observe your plants closely. Use the planting guidelines we have listed and find what works best for you and your garden.
It is also very important to record your personal experiences as this can help you to discover more beneficial companionships as well as incompatibilities. Source.
