General Growing Advice
Using a good quality multi-purpose compost, pot up your plugs into 10cm pots. Once your plug plants have been potted on and labelled, water them in well and grow on for around 5-6 weeks. Water once the compost starts to dry out but remember.
If preferred you can pot on the plugs into hanging baskets, flower bags or pots. Add a slow release plant food like Miracle-Gro Slow Release All Purpose Plant Food to your compost which will give extra nutrients for strong and healthy plant growth.
Keep plants frost free until mid/late May and then harden off before being placed in their final positions when the risk of frost has passed in your area.
Water as necessary giving a liquid feed such as Neudorff Organic Plant Feed as instructed throughout the growing season.
***For packs of 40 plug plants gently remove the small plugs from the tray by pushing up from the bottom using a pencil.
Mint Specific Advice
Mints are well known to be invasive and will try and take over wherever they are grown. They have underground runners that come up here, there and everywhere, so are often best in a tub or container in garden soil. You can also plant mint into an old plastic pot and sink the pot into the ground. This will help to contain the roots.
