Hello @zillah 

To recharge your in-ground herb garden bed without adding more compost or manure and without risking overflow onto your adjacent driveway you can rely on specific pellet and soluble fertilizers that are effective, easy to apply, and suitable for herbs. Here are product-based recommendations:
 

For pellet (slow release) fertilizer, consider using Osmocote Plus Organics Vegetable, Tomato, Herb & Garden Beds. It’s a well-balanced product with an NPK of around 3:1:5 and includes trace elements and some organic content, but in a compact pellet form that won’t raise the soil level. Apply it by sprinkling evenly over the soil surface use roughly 50 grams per square metre and gently mix it into the top 1 to 2 centimetres of soil. Water in thoroughly afterward. This will provide steady nutrients for up to 6 weeks or longer.
 

As a soluble fertilizer option, you can use PowerFeed All Purpose including Flowers, Fruit & Citrus, which has an NPK of 12:1.4:7 and includes liquid compost and trace elements. It's very suitable for herbs, especially leafy ones like parsley, basil, or coriander. Dilute 50 millilitres of PowerFeed concentrate into 9 litres of water and apply directly to the soil or foliage every two weeks during active growth. This gives a fast boost and improves plant resilience without any bulk.
 

If you’re growing more delicate herbs like thyme or oregano, which prefer leaner soil, use the soluble fertilizer at half-strength to avoid overfeeding. Also consider using Seasol (which is a tonic, not a fertilizer) in conjunction with either product. It’s a seaweed-based liquid that doesn’t feed the plant directly but strengthens roots, boosts plant immunity, and supports stress recovery. Use 30 millilitres per 9 litres of water every 2 to 3 weeks.
 

These products are widely available at the store and can be used individually or together, depending on whether you want a slow, steady release (pellets) or faster nutrient access (liquids). This approach keeps your soil level steady and your garden productive without messy runoff onto nearby hard surfaces.

My best advice is to aerate the soil deeply before you add the fertilizers.
