There is no necessity to feed them.

Composts known as Dalefoot are made from sheep’s wool and bracken that has been composted. More recently, comfrey has been added to the mix. Comfrey is said to contain high levels of potassium, phosphorus, and nitrogen. You won’t have to add any additional liquid feed, and when we tested this compost alongside liquid tomato feeds, it scored almost as well as the Best Buy liquid feeds. This means that you won’t have to worry about forgetting to do so. From the beginning to the end of our experiment, our plants remained healthy and produced a total of 7.9 kilogrammes of cucumbers. Garden centres are the places to buy it.

The composition of this compost is quite comparable to that of the Wool Compost for Tomatoes; once again, the primary components consist of wool, composted bracken, and comfrey. It is said that the wool will release nitrogen gradually as it decomposes, and there will be sufficient food for the animal to consume for up to a year. According to Dalefoot, composted bracken is high in potassium content. Because our cucumber plants did not require any additional feeding, they were able to thrive and produce 7.9 kilogrammes of fruits that were of a naturally large size and continued to mature throughout the experiment.

Melcourt now offers a diverse selection of composts, each of which is composed primarily of composted bark, wood fibre, and a touch of coir. The compost used in the feed is also green in colour, and the feed itself is organic (composted garden waste from council collections). In spite of the fact that you might find it more convenient to cultivate your crops with an organic fertiliser, we stuck to our tried-and-true liquid feed for this test. During the course of the experiment, we harvested 7.7 kilogrammes of cucumbers of a high quality from each of the bags.

Instructions for using grow bags

You should start sowing your seeds around the month of March and keep them inside on a sunny windowsill until they have grown to a size where they can be planted in your bag (around 15 centimetres) and the danger of frost has passed.

When you are satisfied with the position of your grow bag, gently roll it to fluff up the compost inside.

You will need to make some cuts in the base of the bag in order to allow any excess water to escape.

In order to properly position your plants, cut along the lines that are marked on the top of the growing bag.

If you only want to put two plants in each bag, you should use the two planting positions that are located on the bag’s outermost edges.

How should plants that are contained in a grow bag be watered?

Be sure to water the bag on a regular basis to prevent it from drying out. In extremely hot weather, you might need to do this as often as three times a day. It is possible to prevent plants from drying out by using an automatic watering system that has a timer. Because the majority of summer vegetables will be stored in the bags for a considerable amount of time, you will need to feed them.

Either add controlled-release fertiliser by mixing it into the compost where you have cut holes before you plant, or once the first fruits have formed, begin giving the plant liquid fertiliser twice a week. Always make sure to administer the medication in accordance with the instructions on the packaging, including the recommended dosage and frequency.
