From our perspective, the root system is our lifeline. For foxgloves like us, we primarily have a fibrous root system with a central taproot that is not as dominant as in some other plants. This network is delicate and responsible for absorbing all the water and nutrients we need from the soil. It also forms a symbiotic relationship with mycorrhizal fungi, which vastly extends our reach and efficiency. When you dig us up, you are severing these critical connections and damaging the fine root hairs that do most of the absorption. The goal of any transplant is to minimize this shock and preserve as much of this intricate system as possible.
Timing is everything for a successful move. The ideal moment to transplant us is during our dormant phase or a period of low growth activity. For biennial foxgloves, this is best done in either early autumn, after we have finished flowering and the seeds have set, or in very early spring before new growth begins to surge. During these times, our energy is focused below the soil on root development rather than on supporting flowers or extensive foliage. Cool, cloudy, or drizzly days are perfect, as they reduce the stress of immediate water loss through our leaves (transpiration) after the move.
The physical act of lifting us from the ground is the most critical step. Please water the soil around us thoroughly a day before the operation. This hydrates us and makes the soil more cohesive, helping to keep our root ball intact. Using a sharp spade, dig a wide circle around the base of our rosette of leaves. Aim for a diameter of at least 8-10 inches to ensure you capture the majority of our root mass. Dig down deeply, then gently lever the root ball out of the ground. Avoid pulling on the stem or foliage, as this can shear off the roots from the crown. The objective is to lift the entire plant with a large, undisturbed ball of soil surrounding our roots.
Our new location should be prepared in advance to minimize the time we spend out of the ground. The new hole should be twice as wide as our root ball and of a similar depth. This allows our tender new roots to easily expand into loose, welcoming soil. We appreciate soil that is rich in organic matter and well-draining. Do not plant us too deeply; the crown (where the stems meet the roots) should sit level with the surrounding soil surface. Placing us too deep can lead to rot.
Once we are gently placed in the new hole and the soil is firmed around us, water us deeply and thoroughly. This settles the soil around our roots, eliminates air pockets, and provides essential moisture. Apply a layer of mulch around our base (but not touching the crown) to help retain soil moisture and regulate temperature. Continue to monitor the soil moisture closely for the next several weeks, keeping it consistently moist but not waterlogged. We may appear wilted or shocked for a short period as we redirect our energy to re-establishing our root system in its new environment. With careful aftercare, we will soon settle in and continue our growth.
