March & April Gardening Tips from Barnsdale Gardens

1. Water Houseplants

With houseplants entering their growth phase, you can start increasing watering. However, be cautious—too much water can do more harm than good. Keep the soil moist but not soggy.

2. Prevent Rose Black Spot

To stay ahead of this common fungal disease, begin spraying as soon as new leaves emerge. At Barnsdale, we use an organic mixture of skimmed milk and water (10:1 ratio) to create a protective barrier. Since this method is preventive rather than curative, reapply after rain to maintain effectiveness.

3. Plant Potatoes

Now is the perfect time to get your early potatoes in the ground. To save time, our team prefers to earth up completely at planting rather than returning repeatedly. This method doesn’t seem to affect yield but frees up time for other essential garden tasks.

4. Pot Up Plug Bedding Plants

If you’re not growing bedding plants from seed, plug-grown varieties are an excellent alternative. Pot them into 8cm (3-inch) containers or use them to fill hanging baskets and wall pots. Keep them in a frost-free greenhouse or conservatory until they’re ready to be moved outdoors.

5. Sow French Beans

At Barnsdale, we love extending the growing season, and early French beans are a must! By sowing now, we often enjoy an early crop of tender, juicy beans. Aim to plant them in the ground by the first or second week of May.

6. Feed Roses

As roses begin to burst into growth, ensure they have the nutrients needed for a spectacular summer display. A proprietary rose food works well, or you can apply a couple of handfuls of pelleted chicken manure for a natural boost.

By tackling these tasks now, you’ll set your garden up for success throughout the year. Happy gardening!
