“ Brand: Phostrogen / Type: Fertilizer „
They are good in so far as they release more feed the hotter the weather, hence you do not get too much green at the wrong time of year. I've used then in my hanging baskets with great success. Sometimes when you buy a new plant you can see the little balls in the soil, no these are not Vine weevil eggs, but slow release feeds. This year I plan to try some on my allotment, see my web page for results.
If you are like me and have loads of plants, in containers, you will know how difficult it can be to fertilize them, using the conventinal method of putting the fertilizer in your watering can then having to water each one seperatly. Well these tablets are so easy, all you have to do is put the tablets into the container, and it releases the fertilizer over a month. If you have a big pot you may have to put about 10 in, but this is a lot quicker that conventional methods. Do they work? In my opinion yes, at the moment all my plants are thriving.
I received a free sample of Phostrogen's slow release plant food. Designed for use in containers and hanging baskets the plant food looks like small green pellets which are mixed into compost. The idea is that they slowing release nutrients into the compost to keep feeding the plants throughout the season. In small areas such as containers and hanging baskets, containing many ornamental and flowering plants, I've found regular feeding is vital to maintain a good display. I put this plant food in a number of hanging baskets and have been very pleased with the result. Without using any other feeds to date the plants are all extremely healthy and flowering profusely - especially the petunias which are in a wall-hung half basket and therefore in a very small amount of compost.
