Power feed

[Small Trees]

I would love to know what mixture of power feed people are using on their trees. Also can a to strong mixture harm the trees?

Hey Small trees
yes a to strong mixture can harm your trees , a lot depends on your soil . If it's a water retentive organic soil then maybe it;s better to go with half strength as the fertilizer can build up in the soil but if it's a free draining inorganic soil then full strength as per instructions should be ok as it will flush out the next time you water the tree deeply

Too strong can harm trees. Only use stronger than makers recommendations if you are willing to take a risk.
I use all fert at full strength as recommended. If the label gives different rates use the one for 'shrubs and trees' or 'veges' or 'potted plants'. Bonsai are not weak little babies despite their size.
