Hi, I'm Jene with Jene's Tropicals in St. Petersburg, Florida. Today, I'm going to discuss how to care for olive trees. You'll need a few materials, such as 2-10-10 bloom booster, hydrated lime and 4-6-8 citrus fertilizer, a pair of sharp pruners and Neem oil. The first thing we need to do is test the soil. Olive trees can take a wide range of soils but prefer a calcareous or a very lime and calcium filled soil. So, if your soil is on the acidic side you'll need to add some lime. The trees begin to produce after about four years and most varieties are self fertile. But to give them a boost, the 2-10-10 bloom booster and fruit set is great to give them during the winter months into early spring. For care throughout the year, just a great fertilizer like 4-6-8 with minor elements is terrific. It is formulated for all of your fruit trees including olives. I would give them that at least twice a year, late spring and mid-summer. Then, also if your tree gets too thick, thin it out. You want the sunlight to come in so you'll have an abundance of fruit and then also it keeps the tree disease free. By chance if you do get leaf spot or a little insect on it, Neem Oil is a great cure all. I'm Jene. Have a great day.
