I have a beautiful almond tree in the backyard of a house I am renting. Part of the tree has died back this year and I see that it is oozing sap. It looks like a pest may have drilled holes (maybe a woodpecker). The person that owns the house is not interested in caring for the tree. What can I do to care for this tree? I have attached photos.
It doesn't look very good. The dead wood needs to be removed. It may be from tree borers. A large infestation can cripple the tree, leading to its removal. Here is more:

Pink if possible
We don't recommend plant vendors or products but I would think you could find a reputable nursery online.
We had a very rainy winter, I'm assuming it has a fungal problem of some sort, but I am unsure of which fungicide I should use to treat it with? Could I get some insight into the problem my tree has please? Many thanks Neshamah
This appears to be shothole disease. Normally, this is controlled with copper fungicides, but if you intend to eat the almonds, then I would opt for a different treatment.
You can try fungicides that contain sulfur. These can be effective, but good sanitation will be more important.

the leaves are dropping What can we do.
Make sure the new pot size is only one or two sizes up. Any larger and you risk overwatering and root rot. The excess soil holds water inviting root rot.
It also could be shock from the new location and repotting. Did you acclimate it to the brighter light? These articles should help:

I was just reading you entry on almonds. If a tree is self fertile, doesn't that mean it doesn't require cross pollination? I think your entry needs editing.
Which article are you referring to? This article below says most almond trees are incompatible and need at least two varieties. It also says if you only have room for one tree, get a self-fertile variety and it lists three.

This article says there are a few self fertile varieties, but you are better off getting compatible combinations of cultivars.

I didn't see it in those articles, but similar articles mention that even though a tree is self-fertile, you will have a larger yield if you get more than one variety.
Hello, I came across your website after reading an article about growing almond trees. It was very informative and I hope you don't mind me reaching out for some advice. I read in your article that some almond trees are self pollinating, whilst others require atleast 2 planted next to each other. In 2021, I tried to plant my own almond trees - I was very lucky, 2 almonds sprouted roots and have now 18 months later grown into small trees approx 6 foot high! The almonds were from a supermarket packet, so I dont know if they will self pollinate or I need a male/female tree for it to give fruit? I wanted to check with an expert what is the best thing to do - is there a way I can check the leaves to know which variety I have grown? Thank you for reading and I appreciate any advice you have to give. Kind regards.
Almond trees are not self-fruitful. You won't be able to tell male from female till you see the flowers. Your best bet is to buy a commercial variety that blooms at the same time as these do. Here is more:

I have a five year old almond tree. It flowered really well in spring and a lot of fruitlets developed subsequently. However, the tree later dropped almost 95% of the fruitlets when they were pea size, while only the remaining 5% are on their way to maturity, and look fine as such.The tree looks healthy with no major signs of concern by looking at it. What could be the reason for this drastic fruit drop? P.s Same thing happened last year as well. The tree flowered quite well, lot of fuitlets developed but only a small amount of fruit reached maturity. The harvested fruit was quite good, both in size as well as taste, but a very tiny amount, sadly!
This specimen is starting to reach maturity. This happens at about 3 to 5 years. With this being said, your first several harvest will be expected to be small. Every year should see a little more fruit until it is prime age for production.
Here are some articles that will help you with their care:
