FAQs
<h2>FAQs for the Boursault Catawba Rhododendron</h2>
<ol>
<li>
<strong>How do I plant the Boursault Catawba Rhododendron?</strong>
<p>Planting your rhododendron requires careful attention to soil, location, and timing. Follow these steps:</p>
<ul>
<li><strong>Choose a location</strong> that receives dappled sunlight and has well-draining, acidic soil (pH 4.5-6).</li>
<li><strong>Prepare the soil</strong> by mixing in organic matter like peat moss or compost to improve drainage and acidity.</li>
<li><strong>Plant in spring or fall</strong> when temperatures are mild. Dig a hole as deep as the root ball and twice as wide.</li>
<li><strong>Set the plant</strong> in the hole so the top of the root ball is level with the soil surface, then backfill with soil, gently tamping down.</li>
<li><strong>Water thoroughly</strong> after planting and mulch around the base to retain moisture and regulate soil temperature.</li>
</ul>
</li>
<li>
<strong>How often should I water my rhododendron?</strong>
<p>Watering needs vary based on climate and soil, but here are general guidelines:</p>
<ul>
<li><strong>Weekly watering</strong> is recommended, adjusting for rainfall. The goal is to keep the soil evenly moist, not waterlogged or dry.</li>
<li><strong>Increase frequency</strong> during hot, dry periods. Early morning is the best time to water, allowing leaves to dry during the day.</li>
<li><strong>Reduce watering</strong> in cooler months to prevent root rot. Always check soil moisture before watering.</li>
</ul>
</li>
<li>
<strong>What is the best fertilizer for rhododendrons?</strong>
<p>Choose a fertilizer specifically designed for acid-loving plants like rhododendrons. Here’s how to fertilize:</p>
<ul>
<li><strong>Apply in early spring</strong> before new growth begins, following package instructions for amounts.</li>
<li><strong>Consider a second application</strong> in late spring or early summer if growth seems sluggish, but avoid fertilizing late in the season to prevent new growth from being damaged by frost.</li>
<li><strong>Water the plant</strong> before and after applying fertilizer to prevent root burn and ensure the nutrients are well absorbed.</li>
</ul>
</li>
<li>
<strong>How do I prune rhododendrons?</strong>
<p>Pruning is essential for maintaining shape and encouraging blooms. Here’s how to prune effectively:</p>
<ul>
<li><strong>Prune immediately after flowering</strong> to avoid cutting off next year's buds. Rhododendrons set next year's flower buds shortly after the current season's blooms fade.</li>
<li><strong>Remove dead or diseased branches</strong> first, cutting back to healthy wood.</li>
<li><strong>Shape the plant</strong> as desired, but be cautious not to over-prune, as this can reduce flowering.</li>
</ul>
</li>
<li>
<strong>How do I protect my rhododendron from pests and diseases?</strong>
<p>Preventive care is key to avoiding pests and diseases. Follow these tips:</p>
<ul>
<li><strong>Inspect regularly</strong> for signs of trouble, such as discolored leaves or sticky residues, which can indicate pests or disease.</li>
<li><strong>Practice good sanitation</strong> by removing fallen leaves and debris from around the plant to reduce hiding spots for pests and prevent fungal diseases.</li>
<li><strong>Use appropriate treatments</strong> like insecticidal soap for pests or fungicides for diseases, but always try less toxic methods first and follow label instructions.</li>
<li><strong>Ensure proper planting and care</strong>, as stressed plants are more susceptible to issues. This includes proper watering, fertilization, and pruning practices.</li>
