I meant that I put Vigoro fertilizer granules in the soil prior to
planting and continue using that compound to re-fertilize. The bag
says it lasts 3 months. My husband just got spikes but I haven't put
them in yet. Located in NJ zone 6-7. The trees are in full sun lining
our driveway. The soil is rather clay-like but we bought screened
topsoil and enriched it when planting. Initially, watering was 1-2
times a week (including rainfall) for the first month or so.


Just guessing, but these are very large trees (20 feet!) and will
need a lot of water until established. If you stopped watering after
a month, they're probably dying of thirst. Try 200 litres per tree
every 15 days. Don't fertilize any more until the survivors are clear,
you'll probably lose some. The good news is they're fairly easy
trees.
