Protective personal equipment
- Eye protection if working above waist height
- Sharp clean pair of secateurs. Use alcohol wipe to clean blade as not to transfer disease.
Remove the 3 D’s completely –
After this, you will then remove any crossing or rubbing stems.
Types of roses and pruning needed
Floribunda (lots of stems & many smaller flowers / shrub/patio roses)
light prune to around 4-7 buds, always looking to keep shape. May remove some stems completely to promote better shape and aeration.
Highbred T (usually three larger main stems with less, larger flowers)
Prune down to between 3-4 buds. Only trying to leave the three strongest stems keeping shape in mind as well.
When pruning roses, the desired shape you are looking for is that similar to a chalice or vase with nothing in the centre to allow the plant to air. This is also achieved by always selecting and outward facing bud on each stem.
The cut you will make be ¼ of inch above each bud at a 45% angle away from the bud. This is to allow the rain/water to run away from each bud to prevent rotting.
Almost 2/3 of gardeners don’t fertilise their plants. This is a big issue as plants need your help to get the nutrients they need to grow best!
The science bit
Like us, plants need certain elements to grow, and some elements are more difficult/impossible for plants to obtain.
The main elements needed
- Oxygen (air in the atmosphere/ water)
- Hydrogen (water)
- Carbon (us humans/ air in the atmosphere)
Other elements needed to be introduce to promote plant growth
- Nitrogen (N) = Promotes healthy leaf growth which plants need to create food through photosynthesis.
- Phosphorus (P) = supports the growth of roots, stems, blossoms and fruits
- Potassium (K) = disease resistance, general plant vigour.
Types of fertiliser
There are only two types of fertiliser – organic and synthetic.
My opinion is to always use organic as it is better for the environment. The reason behind this that most synthetic fertilisers kill beneficial micro-organisms, compared to organically-sourced fertiliser which promotes beneficial organisms which help plants grow.
Forms of fertiliser and application
Granular (powder-like substance)
- Scatter on soil around plant, do not get on stems or leaves as this burn them.
- Water in afterwards
- Long-lasting and with immediate effect
Slow release (pellets)
- Easy to use, just mix pellets in to soil
- Really long lasting
Can apply directly to soil even when planting
Water soluble (liquid)
- Diluted with water
- Fast acting
- Must be applied more often due to speed the plant takes the nutrients
- Incorporated into soil
- Add organic matter
- Slow release of nutrients
- Has other benefits such as preventing weeds
