What supplementary fertilizer should I use?

Spring has definitely sprung and everything in the garden is bursting with growth and potential. Keen gardeners will be sowing seeds and potting them on, and very soon it will be bedding plant time. 

So we all need plenty of good, fresh peat-free compost!

Gardeners will be used to the instruction to apply supplementary feed after the first few weeks. This makes all the difference as composts of all types are typically only supplied with enough fertilizer for the early weeks. SylvaGrow® is no exception. As manufacturers, we cannot add sufficient for the whole season as this would be too strong and plant roots would be scorched. 

There are two ways of adding supplementary feed:

  1. Incorporate controlled release granules at the time of potting. These are readily available in garden centres, also sometimes labelled ‘continuous’ or ‘slow release’.  When added at the recommended rate they will pump out a regular amount of balanced fertilizer, keeping plants well supplied with nutrients, typically for 4 to 5 months. This is a great method for plants destined to stay in the container over the summer. Be aware that the granules do eventually run out and by late summer it’s advisable to commence feeding in order to keep plants looking great well into the autumn.
  2. Liquid feeding is a very useful, quick and easy way of supplementary feeding. There are many brands available in garden centres including those designed for specific purposes such as ericaceous plants or organic growing. Applied at anything from once a week for intensive growing such as tomatoes in growbags to lesser intervals, liquid feeds provide an efficient, immediate source of nutrients. 

As always, be careful with watering and avoid allowing too much run-through of excess water as this will inevitably be taking valuable nutrients with it.

Whichever method you choose, supplementary feeding makes all the difference and your plants will certainly demonstrate this.
