Prunus Avium...

Hello all

This Prunus Avium was collected about 2 months ago near an abandonned railway station.
I managed to collect it with a very decent root-ball and i planted it in 70% Smashed clay and 30% Pine bark.
The tree started to show signs of growth about a month ago and is now showing lots of buds and some leafs.

But, some of the new leafs are burning at the tips.

What maybe causing this?

additional info:

I´ve started fertilizing a couple of weeks ago when the tree was already clearly growing with organic slow release fertilizer.
Like the substrate is very draining i´m watering twice a day.
This week is beeing unseasonably hot with temperatures reaching 30ºC.
The tree gets about 3/4 hours of direct sunlight in the morning.

Hi Liserd

In my country, avium vant a little chalk in the deep soil.

Hope it helps

Kind regards Yvonne

In my limited experience, Prunus & their relatives are susceptible to sun scorch, especially new leaves. Put it in full shade, and gradually expose it until it is in nearly full sun.
Also, there is a chemical, potassium silicate, that helps plants strengthen their cells. Here it is sold as Pro-TeKt. Inquire at a large garden center or a science supply company.

Hello all

Thanks for your quick replies.

Yvonne - The idea is to have a higher PH in the soil right? That´s an intresting idea, because this tree was actually growing in Lime gravel where the old railway platform used to be. But Prunus Avium is very common in Portugal and you see it growing everywere and in all types of soil.

Iris - I´ve changed the tree to a more shady place, it´s really getting hot in Portugal and the sun is very strong, today temperatures are reaching 30ºC again for almost a week in a row.
