are avocado roots invasive
Ensure that the plant receives enough sunlight in the winter if planted in cooler locations. Roots can be invasive, so choose a location with ample space to grow. A windbreak will protect young trees planted in windy locations. Once established, avocado trees will need sun to produce flowers and fruits. The avocado (Persea americana) is a fast-growing, dense, evergreen tree that can reach up to 80 feet tall. It has alternate, glossy, elliptic, dark-green leaves that shed in early spring. The West Indian varieties are scentless, while the Guatemalan and Mexican types smell like anise. The avocado is a shallow rooted tree (most of the feeder roots are in the top 6 of soil) which needs good aeration. They do well if mulched with a coarse yard mulch. Current recommendation is to put approx 1/3 cu yd per tree when planting. Avocado trees like warm ground. Ideally, they should go into the ground from March through June. If they go in during the summer there is always the risk of sun damage because the trees can't take up water very well when young. It is possible for an avocado tree to produce 200 to 300 fruit per tree once it is about 5 to 7 years of age. The avocado however, alternate bears. This means that the tree may produce a large crop one year, and then will produce a small crop the following year. There are lots of variables which will influence this. The sooner the roots get out into the bulk soil, the better the tree will do. Planting mix creates a textural difference between the root ball and the bulk soil and causes water movement problems. Remember, there are 5 million acres of tree crops in California planted without planting mix. Avocado roots are not a problem to cinder block walls. The trees will get to about 30 feet tall and almost as wide so you will need to plant them about 15 feed from the wall. If you want regular fruit bearing you should plant both A and B types. Avocado trees do not tolerate wet soggy soil, but prefer regular deep watering, especially during warmer months. Allowing water to drain completely before the next watering helps prevent root rot. Use drip irrigation to provide slow and deep watering to allow water to penetrate so the roots can reach it. Avocados are sensitive to salt water; therefore, keep this in mind if your water has high salt concentration. Mild salt concentration will cause the tips of avocado leaves to burn. The avocado tree is a native understory tree to the humid and semihumid tropics. It seems to do best at moderately warm temperatures (60 - 85F) and moderate humidity. It can tolerate temperatures, once established, to around 32 - 28F with minimal damage. Are Avocado Roots Invasive??? So, I want to plant a row of avocado trees behind a block wall along our property. The wall is part of a landscape easement we granted for a neighboring community, so I want to be sure I don't plant the trees too close to the wall. I don't want invasive roots to ever be a problem to the wall, or the irrigation that runs near it.
Yes, roots can be invasive.
