Even though fig trees (Ficus carica) do best when planted in the ground in planting zones 8 through 10 according to the United States Department of Agriculture, gardeners in colder microclimates have the ability to offer mother nature a helping hand. You should cultivate your figs in pots so that you can move them to the hottest section of the garden and provide them protection from the elements during the colder months. Fig trees, with their glossy leaves, make appealing container plants and even fruit more abundantly when roots are somewhat pot-bound. Fig trees may be grown in a wide variety of container sizes. Choose the right potting soil, container, and additives for your potted fig so that you may get the most out of your plant.
Planting fig trees and other containerized fruit trees is possible in the majority of organic potting mixes that do not include plant food as an ingredient. Make sure the potting soil is sanitary, and the best way to do this is to use material that has just been acquired. It is possible to sterilise used potting soil by placing it in an oven preheated to 250 degrees and doing so in small batches; but, due to the enormous quantity of soil that is needed, it is more practical to buy fresh potting mix.
The University of Florida Extension suggests using a mixture that consists of one part sand, one part peat moss, and one part perlite or crushed bark as an alternative to purchasing commercial potting mix. After the fig has been planted in the container, the website for the magazine “Organic Gardening” suggests adding a layer of completed compost measuring one inch thick on top of the soil mixture. There should be between 1 and 4 inches of space between the completed level of the soil surface and the rim of the pot.
Pot and Drainage
It is recommended by the California Fig Advisory Board that you choose a container that is capable of holding at least 15 gallons of potting mix. It is recommended for coastal areas that the tree be grown next to a south-facing wall that both absorbs and reflects heat. The container should be lightweight enough to move when your climate requires that you move it to the garage for the winter, but heavy enough to prevent the tree from toppling over in the wind. It is essential that the container include holes for drainage in order to prevent the roots of the fig tree from becoming waterlogged. Even though the fig tree requires lots of light to develop and mature fruit, if the pot itself isn’t shaded, the soil might overheat, causing the tree to wilt. This can only happen if the pot isn’t large enough.
Although fertiliser should not be used in the soil mixture, figs grown in containers may benefit from additional nutrients. During the growth season, apply one application of an organic fertiliser such as compost or manure tea once per month. The California Fig Advisory Board suggests commencing the growth season with an application of a granular slow-release, balanced chemical fertiliser for containerized figs. The fertiliser should be provided in a granular form.
Potting soil does not endure forever. According to the recommendations of the majority of publications, the soil mixture in a potted fig should be replenished every three years. You may combine this step with either repotting the fig into a slightly bigger pot or cutting back the roots of the tree to regulate its growth and enable it to be repotted in the same pot using a new soil mixture. Alternatively, you can repot the tree into the same pot using a new soil mixture.
