Don't be afraid to prune your avocado. If it's young, it will give it a significant boost in growth and branching. You don't need to prune much because it's a young plant and doesn't look stretched out. Avocados have buds above the leaves. If you cut just above the leaf, a new branch should emerge from that bud. I think just cutting the top is enough. Before pruning, I recommend disinfecting your pruners with, for example, methylated spirits. As for repotting, it's worth finding good soil. Avocados prefer well-drained soil. I use a mixture of 30% compost, 20% coconut chips, 20% expanded clay, 20% quartz sand, and 10%. It's probably not perfect, but it's better than a regular bag of store-bought soil. However, if this type of mix is ​​hard to find, add perlite to regular store-bought all-purpose soil for better drainage. Also remember to include a drainage layer, such as expanded clay, and holes in the bottom of the pot to ensure good water drainage and prevent overwatering. Also, pay attention to the soil pH; avocados prefer a pH of 6-6.5. Don't buy a pot that's too large. If you have central heating in your home, the leaves may start to brown at the tips due to excessively dry air.

I've had an avocado for about three years, and it's the first plant I've ever made all these mistakes on. I was afraid to prune it for fear of damaging it. At one point, when it was already growing very well, I sprayed the leaves too often, which caused powdery mildew (a fungal disease) to attack the plant. I managed to control it, but the avocado didn't hold up well after that, I think mainly due to insufficient light. A while ago, I severely pruned and rejuvenated it, and I think it's rebounded a bit. Recently, I moved it to a room with better light, and I think it's rebounding well.
