Perlka 25kg

Calcium Cynamide

Perlka, (Calcium Cyanamide), helps encourage a large population of useful soil bacteria, which research has shown helps to supress soil borne fungal diseases like CLUBROOT in brassicas, RHIZOCTONIA (Dead Root, Brown Patch) in potatoes and SCELEROTINIA in salads.

Perlka (19.7% Nitrogen, 50% Calcium Oxide (CaO) 1.5% MgO), is known for its evenly balanced, long term nitrogen effect. The reason, unlike other nitrogen fertilizers it remains in a stable ammonium form for 6-8 weeks. This enables the plants to take up more ammonium and less nitrate.

The advantages of this are:-

  • Healthy, balanced growth
  • Stronger root growth.
  • Lower nitrate levels in the plant
  • Reduced risk of leaching

If used correctly, Perlka can also help reduce germinating seeds, slugs and wireworms.

How To Use

Rake into the planting area a base dressing of 50g-100g of Perlka per Square Metre during January, February and March.

This rate is ideal for most vegetable crops but you must allow 10 days between applying Perlka and sowing either seeds or transplanting.


Where Brassicas are in a Clubroot infected area, you should apply an additional top-dressing of Perlka at a rate of 50g per square metre 3 to 4 weeks after planting. Ensure that the soil is moist and the plants leaves are dry. Avoid direct contact with the foliage.

Our Approach

In terms of delivery methods and costs, we aim to be as transparent as possible with our costs and be as honest as possible with the timescales that we can get your orders out to you. We do not boast about being the cheapest or the quickest but aim to provide you with quality products at as cost effective price that we can, delivered within reasonable timescales aimed at building long term customer satisfaction.

How Quickly Will My Order Be Dispatched?

We aim to collate and dispatch your order within 5 working days of us receiving it.  Our various delivery partners aim to deliver your order within three working days of us dispatching it. We will always aim to meet this deadline but during extended holiday periods or times of inclement weather this time frame may be extended.

Who Will Deliver My Order?

Due to the complex amount of products, sizes, weights and quantities it is impossible for us to use one delivery partner. Therefore, we aim to use the following delivery channels depending on your orders weight:-

For orders under 2kg will usually be delivered by Royal Mail. Unless they are items like weedkillers and pesticides that will be delivered by DHL*

For orders between 2.1kg and 100kg will be delivered by either Parcelforce or DHL*

For orders over 100kg will be delivered by Pallet Force Network*

*The time it takes to deliver your goods will be down to the delivery partners ability to reach your post code area and them actually being able to deliver the order but if you have not received your goods within 10 days of ordering, please make contact with us immediately in order for us to investigate the problem.

Are There Any Areas That You Cannot Deliver To?

Due to the weight of some of our products, if purchased in large quantities, it would make it financially unviable to deliver to certain Post Code areas. As a matter of course we do not delivery outside of the United Kingdom.

To help you consider if your order can easily be fulfilled we have outlined below where our logistic partners can deliver at a realistic price:-

Up to 2kg we can deliver to all of England, Wales, Scotland & Northern Ireland.

Between 2.1kg and 75kg we can deliver to all of England, Scotland ( exluding Offshore & Scotish Isles) & Northern Ireland. Please note that deliveries to Scotland and Northern Ireland will take between 3 to 4 days and incur additional surcharges. These have been built into the delivery price.

For orders over 75kg we can only realistically deliver to customers in England and Wales.
