This video shows us how to up-pot mulberry trees that were rooted indoors over winter. Today, we will up-pot a Valdosta and a Callie's Delight mulberry tree. We will also stake the Callie's Delight since its branch structure is weaker due to contortion.
Preparing the Soil
Before up-potting, we need to ensure that the soil is suitable for the plants. We have already put some potting soil into the pot, and we need to make sure that the plant fits into it. We then loosen the root ball to ensure that it comes out in one mass.
Root Bound Plants
We usually put more than one cutting in each pot to save space. Often a cutting will fail but to avoid damage to the root system of the successful cutting, we leave the failed cutting in the pot.
When we move plants from inside to outside, they may experience sunburn or sunscald, which can cause leaves to dry and wilt. The leaves of these mulberry trees show signs of sunburn, but the newer leaves look healthy with a good color.
Staking the Trees
The Callie's Delight tree needs support due to its contorted branch structure. We use a three-foot stake to tie the tree's branch to it. However, this is not enough for the Valdosta tree, which will grow taller during the summer.
Trimming the Branches
After up-potting the mulberry trees, we need to trim the branches. We remove all branches except the main trunk, which will become the tree's primary growth point.
Ready to Grow
After up-potting, staking, and trimming the branches, the mulberry trees are ready to grow. We label them and put them in the hoop house for this year.
Up-potting is essential for a plant's growth and development. By following these steps, you can ensure that your plants have a suitable environment to grow and thrive.
