Kinda hard to tell plant condition in the pix, but soil does look mighty wet. These aren't water lillies, lol.

With a plant that size, in a pot that size...use your finger. Stick it in about 1" from the edge, up to the second knuckle, or so. If the soil is 'clumpy' wet, no need to water. (grab a handful of soil. If it doesn't clump, it's dry enough to water. If it clumps, it's 'clumpy', and too wet to add more moisture, lol) If just moist, then it's almost time to water. Give it an exrta 12-24 hours, and then water. MG Moisture Control wll hold the moisture for longer, so overwatering is a concern.

If it's taking the soil 4 or 5 days to dry-out, may want to consider just watering around the drip line of the foliage, or build a little soil-berm 2" out from the base, all around the base. (should look like a donut, with a plant growing thru it's hole) This keeps the water closer to the trunk till absorbed, and needs less water for moisture to penetrate deeper down. Careful not to wash-away soil from base while watering, too. Early on, the roots don't seem to extend much beyond the drip line of the leaves, so soaking the soil outside that circle is unnecessary and possibly harmful in the long run.

Best to start 'em in smaller pots, to avoid this situation, but, there's always next time. :thumbsup:
