Some fruit trees, especially apples, need a pollinator for fertilisation and fruit. Can you remember what you ordered so you can check if they were suitable? Another problem may be late frosts killing blossom before it is pollinated or strong winds and cold weather preventing pollinating insects such as bees from flying.
Ants farm aphids which suck sap and produce honeydew which the ants then feed to to their young. Not good for the plants affected. Blast the aphids off with a spray from a hosepipe and put down poison for the ants or else drive them off with a solution of 5 litres of water mixed with one small bottle of essential oil of cloves (health shop) watered all over the base and roots of the tree.
Remove the suckers as they are coming from the root stock and will reduce the supply of nutrients going to the desired grafted tree.
Remove all grass and other plants form around the base of the tree to a diametre of 1 metre. Loosen the exposed soil with a hand fork and apply a generous dollop of slow release fertiliser such as blood, fish and bone then water well and cover with a mulch of well rotted leaf mold or chipped bark. This will remove competition for nutrients and help the tree produce flwoering spurs for next year.
