I am new to the Magnolia world. I bought a 15 foot tall Brakens Brown Grandlforina. It has been three weeks. I planted during drout but irrigate every other day and water the tree by itself slowly every morning and evening. Here's my problem. Any advise is appreciated. The tree is showing new growth at the end of each limb and also along the trunk. Some limbs have buds which makes me think the limbs will fill out. However, all of the limbs have dead or dying leafs from the trunk to the end - where new growth seems healthy. The leaves are browning in the middle and slowy spreading evenly throughout the whole leaf until it falls off. The limbs themselve appear healthy. I do have some leafs, dead and new growth, that have holes in them which tells me I may need to use a pesticide of some sort. The tree is located in Columbia, Missouri, which is generally considered zone 6. Thanks in advance for any advice!
