Branch out! It’s not too late to plant palms, since they love the heat. Just make sure you start fertilizing them in May and continue to fertilize monthly through September.
Add some golden barrel cactus (Echinocactus grusonii, Zones 9–11) to your landscape. They are extremely hardy, down to 15°F, and those beautiful spines protect them from the harsh desert sun.
Keep your containers watered. This month, as the weather gets hotter, it’s time to pay extra attention to the amount of water your potted plants need.
