Never keep these plants in your backyard


Oleander is a beautiful, tough, long-blooming ornamental shrub. The plant blooms from early summer to mid-autumn with red, pink, yellow, or white flowers.

Although oleander is highly ornamental, it is poisonous to humans and pets. Every part of the oleander is poisonous. Ingesting even tiny amounts of oleander can kill humans or animals.

Oleander is a high-risk plant for both you and your pets. This plant is not suitable for planting in your garden or near your home.

Foxglove is an attractive plant that is grown everywhere. This plant is often cultivated in private yards or gardens because of its beautiful appearance. Its flowers are bell-shaped and can be white, purple, yellow, or pink.



All parts of Foxglove contain several cardiac glycosides, including digoxin and digoxigenin (these substances are highly toxic). Ingestion of Foxglove may cause heart failure or death in humans or pets.

Do not keep these trees in the backyard or near the house

Trees make your garden look more attractive. Also, animals such as your pets and birds will enjoy having a tree in your garden and they can play near it.

But some trees cause trouble for you and you must eliminate them from your tree list.

However, avoid planting female ginkgo in your yard, as it will drop its fruit in the fall. Some gardeners find it a hassle to clean up these fruits in the fall. And, when these fruits rot, they emit an unforgettable smell. If you are unfortunate enough to step on a ginkgo fruit, the horrible smell will stay with you for the rest of the day.

What gardening tools for your plants and trees?


If your backyard or garden is large enough, you can set up a home greenhouse. Many fruit trees can be grown in a greenhouse. In a greenhouse, you can freely adjust temperature, humidity, light, and other conditions. Through manual control, you can harvest fruits all year round.

Raised garden bed

Garden beds are one of the most convenient gardening tools. You can grow fruits, vegetables, cute succulents, and more in raised garden beds. Many gardeners like to have multiple raised garden beds in their greenhouse to manage their plants. By using raised garden beds, you can prevent pests from damaging your plants. Moreover, plants can be cared for without squatting, which is friendly for gardeners with limited mobility.
