Growing root crops can be challenging in small spaces, especially on paved properties. However, this challenge can be overcome by container gardening. Getting topsoil and buying some river sand with compost or composted manure is a one-off payment. Which can be reused after harvesting is possible. Some growers may use sacks, pots, buckets, drums, Fabric bags or polybags. Each method has its pros and cons.
Sacks
PVC sacks are relatively expensive and may not be reusable as the wear and tear outdoors, especially in summer, makes the sacks brittle and likely to tear. They may look unsightly. They are suitable for growing root plants that can be harvested by cutting through the sacks or overturning them. They may degrade before perennial crops are ready, so use them for annual plants.
Polybags
Polybags are affordable, readily available, and do not require additional cost to transport them to your garden. They come in a wide range of sizes. They can be reused for a long time, and harvesting can be done by softening the soil, pulling out the root crops, or overturning the bags. Be mindful to get good quality weatherproof polybags as they will last longer.
Fabric bags
Fabric bags have the best of all worlds. They are attractive, durable, mobile, and come in various sizes. They allow roots to breathe and prevent the tangling of roots as they get pot-bound. They also offer optimal drainage for root crops. Harvesting is also easier by turning the bag inside out. Unfortunately, they are not readily available and can be quite expensive, especially when imported from other countries.
