Much the same way as your body requires certain minerals and vitamins to survive, so does your clematis. In order to grow well and produce beautiful flowers, it needs specific nutrients but it needs to also be applied at the right time. In general, feeding should not be done after September as you don’t want to encourage new growth later in the year which can be damaged by frost and always stop feeding when they come into flower if feeding every couple of weeks with a liquid feed such as tomato feed. Mulch in autumn with farm manure and compost to add the feed to the soil, protect the base from frost and as well as helping retain moisture once spring arrives.
if you want a more specific way of feeding then our next section covers this in more detail.
When to feed clematis
The right time to start feeding your clematis is when the leaf buds have started to produce some growth in early spring. You need to understand that your soil temperature will impact the ability to absorb nutrients for your plant so, it won’t do you any good to feed your clematis until the soil temperature is higher than about 12 degrees centigrade. The root growth slows down and it sometimes even stops when the soil temperature drops below this number. Therefore when the root growth has subsided it doesn’t absorb nutrients as effectively. It will be a waste for you to add food to the soil if your clematis cannot absorb that food.
Usually, by starting to apply a feed around the end of February to early Match, it’s usually about the right time.
Clematis love food but they use fertilizers in different ways contingent upon the season.
How to feed your clematis begins with the right plant feed at the right time.
- In the springtime, once the leaf buds have started to shoot, put a handful of bone meal around the base of the plant and dig then water in.
- You can then feed every 2-3 weeks with a feed such as a tomato feed to promote better flowering but make sure you stop this as soon as they start to flower.
- Finally in autumn, put a handful of sulphate if potash around the base along with a good layer of farm manure and compost as a mulch.
- if you have a clematis that is difficult to apply fertiliser around the base, simply push 3 or 4 slow release fertiliser tablets around the base of the plant instead.
With each of these fertilizers, you should apply as instructed on the box. You should continue alternating these fertilizers in the fashion mentioned above until the end of September. Don’t feed after September except for adding the sulphate of potash and mulch in autumn.
Why food is important
The basic material used in these components is that of a hummus base and when you add humus to the soil it naturally breaks up otherwise compact soil and improve the structure there in. Tangentially it increases water conservation because the plant is able to more effectively hold water. This also brings with it five different strains of beneficial microbes each of which improve your plant’s ability to absorb nutrients and improve its immunity to plant diseases.
The main ingredients found in these fertilizers include nitrogen, phosphorus, and potassium. Nitrogen is responsible for stimulating stem and leaf growth while phosphorus improves root growth and the production of flowers and then potassium comes in and increases the disease resistance and general sturdiness of the plant. Your Clematis simply cannot survive without these three elements because it will be unable to produce the things that it needs. That said your clematis requires nitrogen, phosphorus, potassium, and hummus all of which are found in the right food. With this regimen, you will enjoy a much more rewarding flower display.
