Go girl. No topping. The guava is the one on the far right and by far the biggest. I can almost hear she growing. The first one on the right is a blackberry, which is also growing really strong and well. Finally the one on the far right is a tropicanna, which is much smaller. The two differences were that the tropicanna was planted directly on soil whilst the other 2 were germinated in pellet, and the soil. For the tropicana is only neutral soil (sphagnum and perlite) whilst the other 2 some organic soil was also added.
