Size guide - Tray of 40 Plug Plants 

The most economical way to purchase your plants. Securely rooted, strong plants in mini-plugs of compost. Will need to be transplanted and grown on before planting out ready to flower. Tender varieties will need protecting from frost. Compost volume around 2.6cm deep x 1.8cm square. Foliage height 1.5cm-5cm (depending on variety). Full growing instructions are provided.

Using a good quality multi-purpose compost, pot up your plugs into 10cm pots or use the 6 Pack Cell Plant Trays.  Once your Petunia plug plants have been potted on and labelled, water them in well and grow on for 5-6 weeks in a warm well-lit area but out of direct sunlight.

If preferred you can pot on the plugs into hanging baskets, flower bags or containers.  Add a slow release plant food like Miracle-Gro Slow Release All Purpose Plant Food  to your compost which will gradually 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.

Brookside Nursery Top Tip – Deadhead Petunias regularly to encourage more new flowers.   It is quite easy to just pull off the faded flowers but you need to snap off the developing seed pod too so take off the stem just behind the flower using your fingers or a pair of tiny scissors.
