As Spring feed is fast approaching, I thought I would start this thread to both ask opinions of maple growers and share what I am doing now. Over the past couple of years I have used a 'controlled' release feed compared to what I have done for many many years previous in using a 'slow' release feed. First of all I am not knocking the slow release as it has served me well, but it has a drawback in that it releases the feed no matter the weather or if my tree needs it or not. This I thought to myself in 2019 was not good enough, so I started using a controlled slow release granular feed, that although £2 a kg more expensive than the slow release, lasts the whole season, by only feeding my trees when they need it and the weather is right. This then reduces the need to feed twice, so is actually more economical. I know some of you don't feed and have wonderful soil conditions, but a lot of us don't, so have to supplement our growing substrate. This thread is aimed at those who do need to give their trees a little help. I also understand that some do not advise feeding at all, that's OK also. Everyone to their own. I will not advertise the product I use here, but will give a link to anybody who requests it via a PM. Very interested to hear everyone's thoughts, as it may also help new members to the forum.
