the main roots coming out of the bottom of the pot have gone into the soil underneath and are quite thick. the plants tall -2-3mtrs. i want to repot into larger pots but scared they might die. Will cutting the root ball back to much be dangerous? or cutting the roots that have come out of the pot and into the ground safe for the plant?

Thank you for your email. It does sound like your Magnolia Little Gems are growing extremely strongly if the roots have grown out of the bottom of the pot and into the soil beneath. You will need to pot them into a bigger pot if they continue to grow as they are. Before cutting the roots that are coming out of the pot, apply a Yates product called Yates Waterwise DroughtShield. Water the pots well to begin with and then apply the product. You will need to apply the product several hours before transplanting. This product is in liquid form and comes in a ready to use container. Once sprayed onto the foliage Yates Waterwise DroughtShield will improve the survival of the plant by reducing water loss by up to 50%. Gently take the trees out of their existing pots and transplant. Select pots that are larger in diameter and fill with a good quality potting mix. You will need to loosen the soil around the existing root ball so the root are able to establish into the new potting mix. Backfill the potting mix around the root ball and water in well with a seaweed solution. Keep the pots well watered until the roots start to re-establish and you notice new growth appearing. Yates have just release a new product called Yates Dynamic Lifter Liquid Concentrate. It's a organically certified fertiliser, which contains seaweed, blood&bone and fish meal to help developing new roots and restoring healthy growth. I am sure with some tender loving care your Little Gems will respond well and continue to grow and produce some beautiful blooms for you.
