How do I know when to repot? My oleander tree is over 35 yrs old. I adopted her spring 2011.
Thank you. Mary AnneAnswer:
Wow.. that's really an old plant! It has obviously been looked after well previously. Repotting will ensure that the plants stays vigorous and healthy.These are signs that your plants needs repotting:
- Plant is not looking healthy
- Little or no sign of new growth
- Roots are coming out at the bottom of the pot
- Some plants are able to burst the pot they are in
- Some plants produce so much root that the rootballs starts rising up in the pot. The whole plant is being pushed up by the roots.
- Only roots are visible when the plant is taken out of the pot.
For repotting plants you need a new plant container that is a good bit wider and deeper than the old one. You should have enough room to fit in a good amount of fresh soil, ideally several inches around the root ball and underneath.
Invest into a good quality potting soil that is suitable for the need of your plant. Enquire at your local garden center for the correct soil.How to repot plants:
Carefully lift the root-ball out of the pot and shake out any loose old soil. Remove any damaged or rotten roots.Replant with fresh soil into the new container:
Fill some good quality potting soil into the bottom of the pot and level it out. Then place the plant into the center and ensure it is at the right hight.
Fill the new soil in around the side making sure there is no air pockets left. Firm down well.
Then water the plant well
until the water runs out at the bottom of the container. This will ensure that the new soil settles down and gets into contact with the roots.
After repotting plants into new soil there is no need for feeding
for a while. Start your normal feeding routine again after 6 weeks.
