Overwatering potted tomatoes can lead to yellowing leaves, mottling, and flower drop, according to gardening expert Helen Chesnut. In a recent column, she addressed a reader's concern about heirloom tomatoes planted in two-gallon pots that initially thrived but later developed yellow and mottled leaves, with flowers drying up and falling off.
Signs of Overwatering in Potted Tomatoes
If the soil surface remains constantly damp and the pots feel heavy when lifted, overwatering is likely the issue. Chesnut advises waiting until the top layer of soil has dried before watering again. Compacted soil can exacerbate the problem; gently scuffing the soil surface and poking holes can help dry out the soil and improve air circulation.
Overwatering damages roots, hindering their ability to absorb nutrients like calcium, which is essential for flower retention. Without adequate calcium, flowers dry and drop off. Not all tomato varieties are suited for pots, so checking variety recommendations is also important.
Protecting Prune Plums from Raccoons
In a separate query, a reader asked how to protect prune plums from raccoons. Chesnut recommends wrapping sheet metal around the tree trunk, as raccoons cannot climb it. This simple deterrent works if there is no alternative access from nearby structures or trees.
