last february i cleft grafted many varieties. however, the only variety that flowered imediatly was the olinda valencia orange. since it is recently grafted should remove all flowers to encourage new growth or should keep iit as it is to harvest one or two oranges next season?

here are some pictures

The flowering probably stops other new shoot growth, but your plant still needs to grow bigger, and your plants have a lot of flowers, so it may stay at that size if you leave the flowers.
Also if any fruit is set, it will probably be too heavy for newly grafted plants, it may put pressure on the new graft union ? so unless you really want to get fruit, flower, pollen or seed from any newly grafted plants, I would remove the flowers.
