Pruning
Pruning the Pacific strawberry plants is critical for healthy growth and maximum fruit production. In the early spring, the plants should be pruned by removing any damaged or dead leaves. Removing runners that stem from the plant's central stem is beneficial since they can reduce the plant's fruiting capacity. The runners can be replanted to increase the plant's population or removed altogether.
To promote healthy plant growth, it is essential to remove all flowers and runners during the first growing season. In addition, the plant's foliage should be thinned out to allow for good air circulation and sunlight penetration. The dead or diseased foliage and berries need to be removed promptly to prevent the spread of plant diseases.
Propagation of Fragaria Chiloensis (L.) P. Mill. ssp. Pacifica Staudt
Fragaria Chiloensis (L.) P. Mill. ssp. Pacifica Staudt, commonly known as the beach strawberry or Chilean strawberry, is a low-growing perennial plant mainly found near the coastal regions of western North America. It produces small, sweet-tasting edible fruits, and its leaves and stems have medicinal properties.
Propagation by Runners
The most common and easiest way to propagate Fragaria chiloensis is through runners. As the plant spreads to form a mat-like ground cover, it trails small stems from its nodes, which eventually root and develop into individual plants. To propagate from these runners, select healthy ones that have developed roots and leaves at their ends. Using a sharp knife, sever the runner from the mother plant and transplant it to a new location where it can grow independently. It is best to propagate in the spring or fall when the soil is moist and cool.
Propagation by Seed
Another method of propagating Fragaria chiloensis is through seeds. Collect ripe fruits from the plant as they turn red and soften. Remove the seeds by gently squishing the fruit, washing away the flesh with water, and spreading them on a paper towel to dry for a few days. Sow the seeds in a nursery bed or seed tray filled with a mixture of peat moss, sand, and perlite. Keep the soil moist but not waterlogged and maintain a temperature of around 15-20°C. The seedlings will germinate within two to three weeks, and once they develop leaves, they can be transplanted to their permanent location.
Propagation by Division
Fragaria chiloensis can also be propagated by division, typically during the late winter or early spring when the plant is dormant. Carefully lift the plant using a digging fork and separate the roots into small sections with shoots and roots. Plant these sections in a nursery bed or pots with fresh soil and keep them moist until new growth appears. Once the new plants have developed strong roots and leaves, they can be transplanted to their final location.
