When do you spray apricot trees? A few times a year, starting in the winter. Before the buds on your tree have started to swell, spray it with dormant oil. This will kill off any overwintering eggs before they get a chance to hatch and wreak havoc.
What is the best dormant spray for fruit trees?
Superior oil, also called horticultural oil, is a highly refined miscible oil (up to 99.9 percent pure) that when mixed with water and sprayed on trees will smother overwintering insects and their eggs.
When can I use dormant oil spray?
Dormant oils should be applied in late March or early April before the plants show signs of breaking dormancy (before “bud break”). Dormant oils applied in February or early March are not effective as insects are not actively respiring at this time and, therefore, are not vulnerable to the oil’s suffocating effects.
Why is my apricot tree dropping all its fruit?
Apricot fruit falling off your tree happens because most trees produce significantly more flowers than they need. The odds are that these flowers won’t all be successfully pollinated, so the extras are like insurance for the apricot.

What should I spray my apricot tree with?
The best spray to use is either copper oxychloride or lime sulphur sprayed in alternate years. The first spray should be in late autumn at leaf fall just before the tree enters its dormancy. Spray again at bud swell or bud burst in late winter or early spring.
What is the best fertilizer for apricot trees?
Nitrogen is the nutrient most used by growing apricot trees; it moves throughout the soil, is leached off by normal growth and must be replaced by synthetic or organic compounds. The main source of nitrogen is decaying organic matter.
How do I get my apricot tree to bear fruit?
Since apricots bloom on two year old wood, you have to be really careful how you prune them and realize that any year with heavy pruning may lead to a couple of years without fruit. Leave plenty of old growth to balance the new when you’re pruning apricot trees in the future, but do prune to stimulate fruit production.
What happens if you spray dormant oil too late?
Dormant oil is not named for the dormancy of insects, but for its application during seasons when deciduous trees are leafless. If you apply dormant oil too late in the season — as trees begin budding in spring — you may do more harm than good.
What month do you spray fruit trees?
Spraying fruit trees during the cool seasons, November through March, can help control pests that take up residence in the cracks and crevices, according to Ross Penhallegon, horticulturist with the Oregon State University Extension Service.
Is horticultural oil the same as dormant oil?
Historically, horticultural oils were called “dormant” oils because they were sprayed only when plants, particularly fruit and shade trees, were in a dormant stage of growth before buds opened in the spring. As refining processes improved, “superior” oils were developed.
What month do apricot trees bear fruit?
The blooms appear during early March or the end of February and require dry weather to remain on the tree and produce fruit. Once a tree matures and blooms, it takes between 100 and 120 days for the fruit to be ready for harvest, which usually happens in June or July, depending on your location.
Do you need 2 apricot trees to produce fruit?
Although apricot trees are considered self-fruiting, sometimes it’s best to have more than one tree for pollination purposes. You can even have two different varieties of apricot trees, as having more than one can help if apricot fruiting does not occur.
Do apricot trees produce fruit every year?
Some apricots are also alternate-bearing – meaning, like avocados, they don’t produce fruit every single year. Sometimes they put out every other year, and sometimes every third year. And then, there is the rain equation. Apricots bloom early in February and March – the height of our rainy season in normal years.
What plants should you not use neem oil on?
Neem oil should not be sprayed on herbs such as basil, caraway, cilantro, dill, marjoram, oregano, parsley, or thyme. Care should be taken when spraying neem oil on plants that have delicate or wispy leaves–such as arugula, lettuce, peas, and spinach–since this can result in foliage burns.

How do you make dormant oil spray for fruit trees?
Mix together 1 tablespoon of any lightweight organic oil (again, I used sunflower), a few drops of laundry detergent and a quart of water. Shake well and pour into a spray bottle to use. This mixture controls insects by smothering them, so make sure to use an adequate amount when applying it to your fruit trees.
