Product description
The Petunia Blue Diamond is an aggressive, mat-forming hybrid that produces endless trailing vines covered in sticky, musky-scented leaves and deep-coloured blooms. It is a completely non-hardy plant that requires an acidic soil environment to prevent its foliage from turning a sickly yellow. Because of the deep, tubular shape of its trumpet flowers, it unfortunately provides zero nectar value to the native UK bee population.
For optimal growth and continuous blooming, this incredibly thirsty trailer requires 'normal' soil moisture conditions. Check the hanging basket daily and water it deeply as soon as the top surface of the compost feels dry to the touch. The goal is to keep the root zone consistently moist and spongy, ensuring the fast-growing vines never wilt, while actively avoiding waterlogging the base of the pot.
Please Note: When purchasing plants, please consider that each live item is unique and may therefore differ from the images shown, which are for illustration purposes only. The plant will be supplied in a growers pot. Depending on season, some plants may be pruned back to encourage growth and deciduous plants may arrive without leaves.
Garden Plant Size Guide

Plants in larger pots can be multiple years older than their smaller counterparts with more mature root systems and foliage. This makes them able to thrive as a full size plant in your garden quicker than smaller alternatives.
The most common size of pot that garden plants come in are 9cm/1L/3L/5L this is in reference to the diameter at the top of the pot.
9cm potted plants still remain the most popular cost effective option though, they just may take a little patience to allow them to grow into full maturity once planted in your garden.

Instructions
Top Tip
The sheer speed of growth requires a massive amount of chemical energy to sustain. Apply a liquid feed every single week to replenish the depleted nutrients in the compost. Consistently feeding your Petunia Blue Diamond guarantees it will keep pushing out enormous trumpet-shaped flowers without pausing.
How to Water
You must strike a careful balance to keep these vigorous runners perfectly hydrated. Check the surface daily and water the compost the exact moment the top layer feels dry to the touch. This approach ensures the Petunia Blue Diamond never wilts from thirst or rots from being heavily waterlogged.
How to Plant
Install the young plant near the rim of the container using a slightly acidic multipurpose potting compost. Angle the growing tip slightly downward to encourage the vines to immediately begin their cascade. Giving your Petunia Blue Diamond an edge position allows it to rapidly form a massive curtain of foliage and flowers.
