Use a balanced fertilizer with equal proportions of nitrogen, phosphorus, and potassium. Alternatively, you can use a slow-release fertilizer or compost. Do not fertilize the plant during the inactive growth period or in winter.
Pruning Geranium grandistipulatum Hilliard & B.L.Burtt
Geranium grandistipulatum Hilliard & B.L.Burtt requires minimal pruning. Deadhead the spent blooms regularly to encourage the growth of new flowers. If the plant becomes too leggy, it can be trimmed back by one-third to one-half in early spring. Be sure not to prune too late in the growing season, as this can reduce the plant's ability to survive the winter dormancy period.
Propagation of Geranium grandistipulatum Hilliard & B.L.Burtt
Geranium grandistipulatum Hilliard & B.L.Burtt, commonly known as the large stipule geranium, is a perennial plant that can be grown from both seeds and cuttings.
Propagation from Seeds
The seeds of Geranium grandistipulatum Hilliard & B.L.Burtt can be collected from the plant's seed pods, which ripen in late summer to early autumn. Once the seed pods have turned brown, they can be harvested and left to dry before being stored in a cool, dry place until they are ready for planting in the following spring.
To propagate Geranium grandistipulatum Hilliard & B.L.Burtt from seeds, follow these steps:
- Sow the seeds indoors in the early spring, 6-8 weeks before the last frost, in small pots filled with a well-draining potting mix.
- Lightly cover the seeds with soil, water the pots, and cover them with a clear plastic bag or plastic wrap to retain moisture.
- Place the pots in a warm, bright location, and keep the soil consistently moist.
- Once the seedlings have become established and have grown several sets of leaves, they can be transplanted into larger pots or directly into the garden.
- Before planting outdoors, make sure to harden off the plants by gradually exposing them to outdoor conditions over a period of several days.
Propagation from Cuttings
Geranium grandistipulatum Hilliard & B.L.Burtt can also be propagated from stem cuttings taken in the early summer. Follow these steps to propagate the plant using this method:
- Select healthy stems from the parent plant and make cuttings that are 3-4 inches in length.
- Strip the leaves from the bottom half of each cutting, leaving only a few leaves at the top.
- Dip the cut end of each stem in a rooting hormone, and plant the stem in a well-draining potting mix.
- Water the potting mix, and cover the cutting with a clear plastic bag or plastic wrap to retain moisture.
- Place the pot in a warm, bright location, and keep the soil consistently moist.
- After a few weeks, the cuttings should begin to root. Once they have become established and have begun to grow new leaves, they can be transplanted into larger pots or directly into the garden.
Disease Management
Geranium grandistipulatum is generally a hardy plant, and disease problems are minimal, but it is still susceptible to some common diseases. Here are some of the diseases that may affect the plant and ways to manage them:
- Bacterial blight: This disease causes dark spots on the foliage, which can cause the leaves to die. It can be managed by removing and destroying any infected leaves, keeping the plant dry, and avoiding overhead watering. A copper-based fungicide may also be used.
- Botrytis blight: This fungus causes gray mold on the leaves and flowers, which can cause them to rot. It can be managed by removing and destroying any infected foliage, improving air circulation, and avoiding overhead watering.
- Rust: This fungus causes reddish-brown spots on the foliage, which can cause it to drop prematurely. It can be managed by removing and destroying any infected leaves, improving air circulation, and avoiding overhead watering.
Pest Management
Geranium grandistipulatum is also susceptible to a few pests that can affect its health. Here are some of the pests that may infest the plant and ways to manage them:
- Aphids: These small insects suck sap from the plant and can cause yellowing and distortion of the leaves. They can be managed by spraying the plant with water, using insecticidal soap, or introducing natural predators such as ladybugs to the garden.
- Spider mites: These tiny insects also suck sap from the plant, causing yellowing and mottling of the foliage. They can be managed by spraying the plant with water, using insecticidal soap, or introducing natural predators such as predatory mites to the garden.
- Thrips: These small insects feed on the plant's sap and can cause deformation and discoloration of the leaves. They can be managed by spraying the plant with water, using insecticidal soap, or introducing natural predators such as predatory mites to the garden.
